Designing a More Durable and Pocket-Friendly Fan: QFD and Value Engineering Integration

In today's fast-paced world, electronic equipment has become an essential part of our daily lives, making various tasks easier and more efficient. However, damage to these devices can hinder the smooth running of our daily activities, prompting consumers to opt for repairs over replacements due to the high cost of electronic equipment. A recent survey and interview conducted with 4 Electronic Workshop SMEs in Medan Helvetia District revealed that fans are one of the most frequently damaged electronic devices. This article will explore the integration of Quality Function Deployment (QFD) and Value Engineering methods to design a more durable and pocket-friendly fan that meets consumer needs.

Identifying Consumer Needs through QFD

Quality Function Deployment (QFD) is a method that helps translate consumer needs into product technical specifications. Through the QFD phase I, several technical characteristics were identified as priorities for improvement, including:

Product resistance: A durable fan that is not easily damaged.
Material standardization: The use of uniform and easy-to-obtain materials.
Component costs: More affordable component costs.
Ease of maintenance: Fans that are easily cared for and repaired.
Product dimensions accuracy: Accurate product dimensions and adherence to standards.

These technical characteristics serve as input for the QFD phase II, where several critical parts were identified as priorities for improvement, including:

Quality of Foot Foot Materials: The buffer foot material must be stronger and more durable.
Motor cover resistance: The motor cover must be stronger and resistant to collisions.
The strength of the support foot: The buffer foot must have better strength to withstand the burden.

Applying Value Engineering for Cost Savings

To obtain the best solution, the critical parts were further analyzed using the value engineering method. Value Engineering focuses on increasing product value by reducing production costs without compromising quality. In this study, a 3-dimensional anthropometric measurement was used to determine the ideal dimensions of fans, ensuring they are ergonomic and comfortable to use.

Value engineering analysis results provided several alternative material improvements that can reduce the cost of fan production, including:

Foot support: Changing the material of the foot pipe from carbon steel to alternative materials that are stronger and more economical.
Motor Cover: Changing the Motor Cover Material from Polypropylene Plastic to Alternative Materials that are more durable and lighter.
Supporting foot: Changing the supporting foot material from synthetic rubber (SBR) to an alternative material that is more durable and has a stronger grip.

Conclusion

The integration of QFD and Value Engineering has proven effective in designing fan products that are more durable, pocket-friendly, and in line with consumer needs. Through analysis of consumer needs and evaluation of critical components, this research has succeeded in obtaining more economical alternative materials without compromising product quality.

This research can serve as a reference for fan manufacturers to improve their product design and achieve a competitive advantage in the market. Additionally, the use of alternative materials that are more environmentally friendly can also support industrial sustainability efforts.
