Product Design Improvement of Water Dispenser Tap using Triz Method

To produce the best solution for improving any product design that should be able to satisfy the design requirements (i.e., faster, better and cheaper), there were several stages typically involves the root cause analysis and idea generation activities. In this paper, product design improvement of a water dispenser is demonstrated using Theory of Inventive Problem Solving (TRIZ) method. The objective of this study was to find out the design solution which was able to solve the problem of water spill out that occurred after dispensing water from the dispenser tap. TRIZ Function Model and Engineering Contradiction method were used to model the problem, followed by TRIZ Contradiction Matrix and 40 Inventive Principles to generate potential solutions. The design improvement process based on the TRIZ method generated new concept design of water dispenser tap component which was able to eliminate the water spill out problem, while maintaining the existing dispensing function. In addition, the new dispenser tap conceptual design also required less component to operate compared with the existing design, hence, lowering the product cost

Development of Conceptual Vehicle All-Wheel-Nuts Remover

As the standard of living in Malaysia has increased, most of the families have at least one vehicle, typically, car, to move easily and quickly. With the increment of the number of cars in the road, the number of cars’ problem due to tyre failure has increased. Often, the car is provided with tyre wheel nuts remover and jack for instance spare tyre replacement. Nevertheless, due to the difficulty in applying the required torque to remove the nuts, most of the time, driver rely on the tow truck and available nearest mechanic to solve the problem. This always happen to the elderly or female drivers. Based on the capability of torque application by these drivers, a vehicle all-wheel-nuts remover is designed. The remover is designed to be ergonomic to be used, easy maintenance, easy storage, easy to handle and able to remove all nuts at once. The design of the remover is based on standard pitch circle diameter (PCD) of 100 mm and 4 numbers of nuts for most of the cars available
