Abstract

Computer mouse has been a staple in the world of computers since its introduction in the 1960s. In fact, it is one of the two most important devices in the computer’s graphical user interface other than the keyboard. Computer mouse has gone through a series of evolution. As of now, the design of the computer mouse has been expanded indefinitely. From the trackball mice to the current laser and light-emitting diode mice, and from the regular horizontal mice to the exceptional ergonomic mice, computer mouse indeed has come a long way since its invention. The ultimate purpose of this project is to develop a new conceptual design of an ergonomic mouse with the purpose of achieving a healthy workstation among the users. The relative knowledge of the topic is sourced from the past studies. In specific, there are three objectives in this project and all are converging towards the same ultimate goal. The first of which is to generate the conceptual designs for the new ergonomic mouse. Five conceptual designs were presented via TRIZ-PDS-morphological chart approach. The second objective is to select the best material for the mouse. Literatures related to the potential ergonomic mouse material were studied and information were extracted where necessary. Then, the best material was determined after utilising the analytic hierarchy process, one of the multiple criteria decision-making technique. The third objective for this project is to select the best design concept of the mouse. The analytic hierarchy process was also applied in fulfilling this objective. The results showed that the best material and design concept for the new ergonomic mouse is the man-made cellulose/PLA and Concept 2 respectively. The best material had scored a priority of 0.4251 (42.5%) and the best design concept had scored a priority of 0.4220 (42.2%). This report has provided an insight on designing a new product in concurrent engineering perspective and has the potential for further research.
