Abstract

This study introduces Conceptual Design of Self-Organised USB Charger Cable by using Inventive Problem Solving (TRIZ) as a solution to the problem of clean and neat workspace. This study aims to establish and determine the ideal component conceptual design based on product design criteria, with a focus on the ideal solution to retain the length of the charger cable when in use. This problem occurs when the user had difficulty in maintaining clean and neat workspace. Inventive principles were solved using the TRIZ contradiction matrix and 40 engineering instruments. This research aims to study and analyse design solution of self-organised USB Charger Cable by using TRIZ method. TRIZ technique is effective in assisting in outlining issues with organised solutions, in addition to having the capacity to provide unique ideas and solutions. Few design methods were used during the design and fabrication process such as TRIZ Inventive Principle. Self-organised USB Cable is a built-in charger cable that has space to store the cable by rolling or keeping it in depending on the findings and the final design concept. This method of TRIZ have been used to make new design and concept for the self- Organised cable organiser. 39 Engineering Parameters were included in the study. Besides, to design and fabricate a self-organised USB Cable organiser prototype. Concept generation by using TRIZ 39 Engineering Parameters Method, and weighted rating evaluation method are implemented to build a self-organised USB Charger Cable. In order to construct a solution for the contradiction, a number of general solutions, such as taking out, self-service, segmentation and parameter changes, were picked based on the TRIZ 40 innovative principles. The design of the finalised self-organised USB Charger Cable was designed by using SOLIDWORKS. This study recommend that System Usability Scale consists of 3 main categories, which is Usability, Applicability and Effectiveness. A usability test will be conducted to gather user feedback on the self-organized USB charger cable prototype. Concept design 6 is selected according to the Weighted Rating Evaluation Method results. Based on the result of System Usability Scale, it shows that 84.2% had positive perception toward the design of the prototype and this indicated the conceptual design are relevant for users.
