Combinatorial innovation and lifecycle analysis of low-carbon energy technologies in China

Measuring the lifecycle of low-carbon energy technologies is critical to better understanding the innovation pattern. However, previous studies on lifecycle either focus on technical details or just provide a general overview, due to the lack of connection with innovation theories. This article attempts to fill this gap by analyzing the lifecycle from a combinatorial innovation perspective, based on patent data of ten low-carbon energy technologies in China from 1999 to 2018. The problem of estimating lifecycle stages can be transformed into analyzing the rise of fall of knowledge combinations. By building the IPC co-occurrence matrix, this paper demonstrates the lifecycle evolution of technologies graphically constructs an efficient quantitative index to divide lifecycle stages. The mathematical measurement can effectively reflect the evolutionary pattern of technologies. Additionally, this article relates the macro evolution of lifecycle to the micro dynamic mechanism of technology paradigms. The sign of technology maturity is that new inventions tend to follow the patterns established by prior ones. Following this logic, this paper identifies different trends of paradigms in each technology field and analyze their transition. Furthermore, catching-up literature shows that drastic transformation of technology paradigms may open “windows of opportunity” for laggard regions. From the results of this paper, it is clear to see that latecomers can catch up with pioneers especially when there is a radical change in paradigms. Therefore, it is important for policy makers to capture such opportunities during the technology lifecycle and coordinate regional innovation resources.

A Self-Adaptive Neighborhood Search Differential Evolution Algorithm for Planning Sustainable Sequential Cyber–Physical Production Systems

Although Cyber–Physical Systems (CPSs) provide a flexible architecture for enterprises to deal with changing demand, an effective method to organize and allocate resources while considering sustainability factors is required to meet customers’ order requirements and mitigate negative impacts on the environment. The planning of processes to achieve sustainable CPSs becomes an important issue to meet demand timely in a dynamic environment. The problem with planning processes in sustainable CPSs is the determination of the configuration of workflows/resources to compose processes with desirable properties, taking into account time and energy consumption factors. The planning problem in sustainable CPSs can be formulated as an integer programming problem with constraints, and this poses a challenge due to computational complexity. Furthermore, the ever-shrinking life cycle of technologies leads to frequent changes in processes and makes the planning of processes a challenging task. To plan processes in a changing environment, an effective planning method must be developed to automate the planning task. To tackle computational complexity, evolutionary computation approaches such as bio-inspired computing and metaheuristics have been adopted extensively in solving complex optimization problems. This paper aims to propose a solution methodology and an effective evolutionary algorithm with a local search mechanism to support the planning of processes in sustainable CPSs based on an auction mechanism. To achieve this goal, we focus on developing a self-adaptive neighborhood search-based Differential Evolution method. An effective planning method should be robust in terms of performance with respect to algorithmic parameters. We assess the performance and robustness of this approach by performing experiments for several cases. By comparing the results of these experiments, it shows that the proposed method outperforms several other algorithms in the literature. To illustrate the robustness of the proposed self-adaptive algorithm, experiments with different settings of algorithmic parameters were conducted. The results show that the proposed self-adaptive algorithm is robust with respect to algorithmic parameters.

Exploring Electric Vehicle Patent Trends through Technology Life Cycle and Social Network Analysis

In response to environmental and energy challenges, electric vehicles (EVs) have re-emerged as a viable alternative to internal combustion engines. However, existing research lacks a comprehensive analysis of the technology life cycle of EVs in both global and South Korean contexts and offers limited strategic guidance. This study introduces a novel approach to address these gaps by integrating the S-curve model with social network analysis (SNA), time series analysis, and core applicant layouts. The study specifically utilizes the logistic curve to model technology growth. It applies SNA methods, including International Patent Classification (IPC) co-occurrence analysis and the betweenness centrality metric, to identify the stages of technological development and sustainable research directions for EVs. By analyzing patent data from 2004 to 2023, the study reveals that EV technologies have reached the saturation phase globally and in South Korea, with South Korea maintaining a two-year technological advantage. The research identifies sustainable research directions, including fast charging technology and charging infrastructure, battery monitoring and management, and artificial intelligence (AI) applications. Additionally, the study also determined the sustainability of these research directions by examining the sustainability challenges faced by EVs. These insights offer a clear view of EV technology trends and future directions, guiding stakeholders.

Global Mobile Inventors

The number of Global Mobile Inventors (GMIs), inventors moving across borders during their career, has increased more than tenfold over the past two decades, and the corridors of mobility have shifted towards a growing presence of emerging markets. We document that GMIs that have patented in a given technology before moving are 70% more likely to be among the pioneering inventors in that technology once they arrive at destination, which we interpret as evidence of knowledge diffusion across borders. Returnees, which are typically inventors from emerging markets that go back after having spent some time in the US and other advanced economies, are twice as likely to file pioneering patents once returned than migrants when arriving abroad. Finally, we find that the more central the GMIs in the network of inventors during the early stages of the technology life-cycle at destination, the faster the technology-specific knowledge is absorbed by local inventors.

Usability Checklists for Health Technology: Case Study and Experts' Opinions.

Application of usability evaluations throughout the health technology lifecycle is necessary to improve the efficiency, safety, and effectiveness of health service delivery. Unfortunately, technology vendors and healthcare organizations may not have funding, time or expertise to conduct usability studies. In this paper, we describe how usability checklists can potentially fill this gap. First, we introduce a case study using a checklist to identify usability issues with a primary care dashboard. Then we provide an expert summary of the strengths and limitations of usability checklists. Findings suggest that checklists are efficient to identify important usability issues. They can be used effectively by project team members - including clinicians - without formal usability training. However, checklists should complement rather than replace usability evaluations with representative users.

A Data Analytics and Machine Learning Approach to Develop a Technology Roadmap for Next-Generation Logistics Utilizing Underground Systems

The increasing density of urban populations has spurred interest in utilizing underground space. Underground logistics systems (ULS) are gaining traction due to their effective utilization of this space to enhance urban spatial efficiency. However, research on technological advancements in related fields remains limited. To address this gap, we applied a data-driven approach using patent data related to the ULS to develop a technology roadmap for the field. We employed Latent Dirichlet Allocation (LDA), a machine learning-based topic modeling technique, to categorize and identify six specific technology areas within the ULS domain. Subsequently, we conducted portfolio analytics to pinpoint technology areas with high technological value and to identify the major patent applicants in these areas. Finally, we assessed the technology market potential by mapping the technology life cycle for the identified high-value areas. Among the six technology areas identified, Topic 1 (Underground Material Handling System) and Topic 4 (Underground Transportation System) showed significant patent activity from companies and research institutions in China, the United States, South Korea, and Germany compared to other countries. These areas have the top 10 patent applicants, accounting for 20.8% and 13.6% of all patent applications, respectively. Additionally, technology life cycle analytics revealed a growth trajectory for these identified areas, indicating their rapid expansion and high innovation potential. This study provides a data-driven methodology to develop a technology roadmap that offers valuable insights for researchers, engineers, and policymakers in the ULS industry and supports informed decision-making regarding the field’s future direction.

The Technology Innovation of Hybrid Electric Vehicles: A Patent-Based Study

A hybrid electric vehicle (HEV) is a relatively practical technology that has emerged as electric vehicle technology has gradually matured. The analysis of the HEV patent lifecycle is crucial for understanding its impact on the development of this technology. This lifecycle tracks the progress of HEV technologies from their inception and patenting, through their market adoption, and to the expiration of their patent protection. In this study, we aimed to evaluate the technology lifecycle of the HEV industry using the growth S-curve method. The purpose of this study is to describe the technological lifecycle trajectory and current stage of the HEV industry, as well as the technical stages of each sub-technology, to facilitate better decision making. As part of this study, we used patent family data collected from the Derwent Innovation Index database from 1975 to 2022 and established an S-curve model for HEVs and their sub-technologies using logistic regression. In 2022, the technological maturity of HEVs reached 44%. The sub-technologies with the most substantial diffusion capabilities are energy management, propulsion systems, and cooling circuits. According to predictions, the saturation period for the patent family quantity related to HEVs is estimated to be around 53 years.

Nasal Drug Delivery and Nose-to-Brain Delivery Technology Development Status and Trend Analysis: Based on Questionnaire Survey and Patent Analysis.

Nasal administration is a non-invasive method of drug delivery that offers several advantages, including rapid onset of action, ease of use, no first-pass effect, and fewer side effects. On this basis, nose-to-brain delivery technology offers a new method for drug delivery to the brain and central nervous system, which has attracted widespread attention. In this paper, the development status and trends of nasal drug delivery and nose-to-brain delivery technology are deeply analyzed through multiple dimensions: literature research, questionnaire surveys, and patent analysis. First, FDA-approved nasal formulations for nose-to-brain delivery were combed. Second, we collected a large amount of relevant information about nasal drug delivery through a questionnaire survey of 165 pharmaceutical industry practitioners in 28 provinces and 161 different organizations in China. Third, and most importantly, we conducted a patent analysis of approximately 700+ patents related to nose-to-brain delivery, both domestically and internationally. This analysis was conducted in terms of patent application trends, technology life cycle, technology composition, and technology evolution. The LDA topic model was employed to identify technological topics in each time window (1990-2023), and the five key major evolution paths were extracted. The research results in this paper will provide useful references for relevant researchers and enterprises in the pharmaceutical industry, promoting the further development and application of nasal drug delivery and nose-to-brain delivery technology.

PHANTOM CHAINS TONTOR OF BIONIC OBJECT'S MOVEMENTS OF AUTOMATED SYSTEMS. Part 1

This presented work results provides an understanding of how phantom life cycle diagrams of abstract objects can be formed based on the conditions of their existence. Thus, an essential feature of the action of these objects is their possibility of application in automated systems, which is an important aspect of the development of technical bionic means and systems. The problem of using a phantom for modeling actions, movements of objects in space, features of the obtained results is quite widely used in various fields of scientific research. However, there remain tasks related to understanding how the main actions of robotic working bodies of automated systems take place. Thus, it becomes possible to create formalized models of the processes of performing actions of experimental objects in medicine, industry, astronomy, based on phantom constituents of chain and step geometric elements. Thus, it is possible to present similar bionic objects in medical automated systems, which refers to the design of bionic prostheses, exoskeleton systems, as well as systems for scientific research of biomechanical properties of objects. At the same time, we analyze the peculiarities of motor movements, for which we create and analyze phantom models of TONTOR steps and their combination into phantom chains. Prospects for further research, which will be presented in the next part of this work, are the creation of analytical models of phantom features of the existence of various bionic technical means in view of their connection between the volume of the abstract object and the phantom. Similar analytical approaches make it possible to determine the phantom matrix model of the life cycle of a bionic abstract object in automated systems.

RECYCLING OF PHOTOVOLTAIC CELLS – A REVIEW

The growth of solar energy has been remarkable between 2013 and 2022, with a doubling of capacity from 80 GW to 197 GW. To recover valuable materials and mitigate environmental impact, it is imperative to have effective waste management practices in place. While recycling technologies are still in the experimental phase, the EU has put in place legal frameworks for manufacturer liability. There are continuous efforts being made to develop commercially viable technologies for the management of end-of-life PV module waste. An important part of the system of renewable sources is the establishment of a high-quality and efficient waste management system, which is contained within the concept of the circular economy. PV modules will at some point reach the end of their life cycle, which is estimated to be around 25 years, and become waste, therefore a lot of effort is currently being put into research and development of different waste treatment technologies of PV modules. They are still in the experimental phase, and few technologies become commercially available. Also, the management of waste generated at the end of the life cycle of photovoltaic technology is not yet fully regulated. However, at the level of the European Union, there is a legal framework for the liability of PV module manufacturers according to Directive on electric waste and electronic equipment. This paper is a detailed review of recycling technologies based on existing literature.

A circular economy roadmap for solar photovoltaics

Solar photovoltaics (PV) and other clean energy technologies are increasingly being deployed as an environmentally responsible and economic approach to energy system decarbonization. The shift from fossil fuel-centric to material-centric equipment has also shifted the consideration and management of environmental and societal impacts across the technology life cycle. Societal desire to reduce raw material needs, mitigate supply chain social and governance challenges, and take advantage of the reuse and recycling capabilities of materials has enhanced interest in regenerative economic models, called circular economies (CEs). A recent critical review documented that solar PV is on a “path towards increased circularity,” but the need remains to expand activities beyond recycling to a broader set of environmental and policy activities to fully realize the benefits [1,2]. Thus, the goal of this research roadmap is to facilitate and accelerate the transition to a solar PV CE by 1) highlighting current opportunities for PV value chain stakeholders to adopt circular strategies and 2) assessing research and development (R&D) needs that can be addressed in the short term to advance a CE for the solar industry.

Exploratory and exploitative linkages and innovative activity in the offshore renewable energy sector

PurposeThis paper examines the relationship between open innovation (measured by exploratory and exploitative linkages) and firm-level innovative activity in the offshore renewable energy (ORE) sector.Design/methodology/approachA unique, purpose-built survey that targeted firms operating in the ORE sector and its supply chain was used. The data provides novel insights into the research activities and networking capabilities of an industry in its infant stages of development. Regression models are used to estimate the relationship between firm-level external linkages and innovative activity.FindingsExploratory linkages are positively related to more innovative activity. This relationship is subject to diminishing returns, distinguishing the ORE sector from other sectors. Collaborating with suppliers and accessing scientific journals are conducive to research and development (R&D) activity and process innovation, whilst collaborating with customers is associated with the decision to introduce new products and processes.Originality/valueThis study provides evidence of a positive, but curvilinear, relationship between external knowledge linkages and innovative activity, adding novel insights into the relationship between open innovation (OI) strategies, research and innovation outcomes for firms predominantly in the introductory stages of the technological life cycle with limited commercialisation experience. The nuanced finding that specific linkages matter for certain research and innovation (R&I) outcomes adds deeper complexity to March’s (1991) framework, where tailoring certain exploratory or exploitative linkages to specific innovation activities is important.

Prospective life cycle assessment to support eco-design of solid oxide fuel cells

ABSTRACT Solid oxide fuel cells (SOFCs) could have great application potential and technological development. However, there are no studies that have quantitatively and rigorously estimated the environmental impacts in the future scenario. This study fills this gap through an innovative approach consisting of patent-based technological forecasting and prospective life cycle assessment (LCA). The analysis of the 58 selected patents reveals that future SOFCs could have (on average) +53% specific power which could lead to a 56% mass reduction compared to current SOFC. The prospective LCA shows an average global warming potential (GWP) reduction of 50%. The future tubular layout is more sustainable than planar one by about 15%. GWP decreases with increasing specific power and in cells with smaller sizes and thicknesses. Finally, the ductile future SOFCs, dedicated to mobile applications and dynamic loads, have a GWP greater than future stationary SOFCs, but still equal to half of the current SOFCs. All these results therefore confirm the potential of the patented SOFC developments on environmental sustainability, arguing in favour of their industrial development and a more massive application in the future.

A collaborative approach to manage continuous service innovation

In dynamic market environments, companies look beyond organizational boundaries to pursue competitive advantages. When they collaborate, organizations might develop innovative service offerings and stay relevant in the market over time, enabled by advances in technologies. However, the collaborative dynamics underpinning strategies for continuous service innovation remain underexplored, such that extant research predominantly adopts an organization-centric perspective and fails to offer a comprehensive view of collaborative innovation initiatives that integrate consecutive projects across technology life cycles. To bridge these gaps, the current research applies an action research approach to the supply chain of organizations dedicated to complex technology delivery and maintenance in the maritime industry. The findings specify not just collaborative strategies for continuous service innovation but also the influential factors and operational service attributes crucial to their success. Therefore, this study proposes collaborative strategies for continuous service innovation, with the assertion that collaboration opportunities are integral to developing and managing novel services. Furthermore, this article introduces a technology life cycle perspective to the management of continuous innovation systems, which demand a collective approach to accommodate multiple technology frequencies (e.g., upkeep, update, upgrade), particularly in multi-technology contexts.

Investigating the research and development status and trends of constructed wetlands: A bibliometric and patent analysis

Constructed wetlands (CWs) have been globally studied over the past few decades as promising energy-efficient and cost-effective green technology. As a result, it is critical to monitor the research and development (R&D) trend, research and innovative hotspots, sustainability status, development limitations, and key contributors at the forefront of this green infrastructure. The current study employs bibliometrics of research publications and patent analysis as the most effective carrier of technological information and significant R&D metrics to track the R&D trends in the field. Using the logistic model for S-curve analysis we predicted the technological life cycle of CW. Results from the study showed that (1) scientific publications and patents on CWs have experienced a steady growth at an annual rate of 22.2 % and 17.9 % respectively (2) China had the highest research and patent publications 77.6 % and 84 % respectively. However, the USA stood out as the most international collaborator in the field. (3) The analysis of co-occurrence keywords indicates that the significant hotspot of constructed wetlands research includes: “removal efficiency”, “performance”, and “wetland plants”. Whereas “sedimentation tank”, “inlet water pipe”, and “filter bed” were observed to be the innovative hotspots for CW development. (4) The S-curve analysis from the articles and patents shows technical saturation points of 4706 and 251 respectively with an estimated remaining time, an average of 15 years, which implies that presently the growth of CW is almost stagnant and has barely little potential for further growth. The current limitations of CW development and directions for future studies were outlined.

How does technological value drive 6G development? Explanation from a systematic framework

As a novel form of infrastructure, 6G is poised to become an indispensable component of the future digital economy and serves as a solid guarantee for the development of human society. Given that technological innovation inherently possesses purpose and direction, its progress cannot be divorced from the correct value orientation. However, scholarly attention towards investigating the value proposition of 6G remains limited. Establishing a scientific and rational value system assumes paramount importance in shaping future investments and deployments of 6G and fostering advancements in associated technologies. This paper presents a comprehensive analysis of the value proposition of 6G, examining it from multiple perspectives including economic, social, ecological, cultural, and strategic dimensions. In addition, we explore the four vertical value dimensions of nation, industry, firm and individual. By integrating the technology life cycle framework into our consideration, we elucidate how value is realized and evolves across different stages. The primary objective of this paper is to enhance comprehension regarding the value of 6G and forthcoming technologies while extensively expounding on the potential contributions of 6G towards future economic and social development.
