Switch Product Improvement Design with the Integration of QFD and DFMA Methods at PT Voltama Vista Megah Electric Industry

Introduction

The design process plays a crucial role in switch production, encompassing not only product functions but also manufacturing processes, assembly time, and production costs. In this context, research conducted at PT Voltama Vista Megah Electric Industry aimed to evaluate the design of existing switch products by integrating the concepts of QFD (Quality Function Deployment) and DFMA (Design for Manufacture and Assembly). This study aimed to explore the effectiveness of combining these two methods in improving switch product design.

Understanding QFD and DFMA Methods

Quality Function Deployment (QFD)

QFD is a method that focuses on translating customer needs and expectations into product design aspects. It helps companies to capture customer voices and deploy them into product design, ensuring that the final product meets customer requirements. QFD involves a series of steps, including:

Identifying customer needs and expectations
Translating customer needs into product design aspects
Deploying product design aspects into production processes

Design for Manufacture and Assembly (DFMA)

DFMA is a method that focuses on developing design towards the simplest form, while maintaining market needs and product functionality. It involves a series of steps, including:

Identifying components that do not provide added value
Eliminating or combining these components without reducing product functionality
Optimizing product design for manufacturing and assembly processes

Research Methodology

The research conducted at PT Voltama Vista Megah Electric Industry involved the following steps:

Initial Design Analysis: The initial design of the switch product was identified through the QFD method.
Assembly Time Measurement: Measurements were taken using the Stopwatch Time Study method to get accurate time data.
Design Improvement: The research continued on the improvement of product design to reduce assembly time and component costs.
Assembly Process Chart: The most optimal sequence of assembly was evaluated using the Assembly Process Chart.

Results and Analysis

The results of the research showed a significant decline in assembly time, number of components, and assembly cost. The assembly time was reduced by 17.83%, the number of components was reduced by 11.43%, and the assembly cost was reduced by 17.82%. The integration of QFD and DFMA methods allowed companies to focus on both technical aspects and customer needs and expectations.

Analysis of the Impact of Design Improvement

The application of the QFD and DFMA method has a very positive impact on switch product design. Not only does it increase time efficiency and reduce costs, but it also contributes to better product quality. By reducing the number of components, the possibility of assembly errors can also be minimized, which in turn increases the level of customer satisfaction.

Conclusion

The design of switch product repair at PT Voltama Vista Megah Electric Industry shows that by using the right methodology, companies can achieve better efficiency in production. Through a combination of QFD and DFMA, companies are not only able to reduce production time and costs but also improve product quality and functionality. This approach creates significant added value for companies and customers. The success of the implementation of this design improvement can be a model for other industries that want to improve efficiency and effectiveness in the production process.

Recommendations

Based on the findings of this study, the following recommendations are made:

Companies should consider integrating QFD and DFMA methods in their design process to improve efficiency and effectiveness.
Designers and engineers should focus on simplifying product design while maintaining market needs and product functionality.
Companies should prioritize customer needs and expectations in their design process to ensure that the final product meets customer requirements.

Limitations of the Study

This study has several limitations, including:

The study was conducted in a single company, and the results may not be generalizable to other industries.
The study focused on switch product design, and the results may not be applicable to other product categories.
The study did not consider other factors that may affect design improvement, such as supply chain management and inventory control.

Future Research Directions

Future research should focus on exploring the application of QFD and DFMA methods in other industries and product categories. Additionally, research should be conducted to identify other factors that may affect design improvement and to develop strategies for implementing design improvement in companies.
