Abstract
This research paper aims to address several challenges associated with the use of walkers, namely, the problem of incorrect posture leading to physical discomfort, increased product requirements, lack of collapsibility affecting portability, and storage issues caused by the walker's large size. To effectively overcome these challenges, a combined approach of Quality Function Deployment (QFD) and the Theory of Inventive Problem Solving (TRIZ) is employed. The House of Quality (HOQ) is utilized as a tool to analyze the relationship matrix within the HOQ and the characteristics of the product. The TRIZ method is applied, leveraging 39 parameters and 40 Inventive Principles, to solve the identified problems. The concept development phase encompasses various techniques such as hand sketches, a sketchbook, Solidworks, and other pertinent tools. Subsequently, a prototype is developed and subjected to a validation survey. The results of the survey demonstrate a high level of satisfaction among the respondents, indicating that the walker successfully fulfills their requirements.
