Design for Assembly Integration Approach with Kano Models and Design for Serviceability in Product Design

In today's fast-paced industrial world, the effectiveness of the production process heavily relies on good product design. A prime example of this is the pellet extruder machine, which transforms raw materials such as fish meal, fine bran, mocaf flour, and fresh water into solid pellets or granules. However, a common issue in the production of these machines is the disruption in product assembly due to the sediment of raw materials formed after the operational process. This problem was observed at the Pellet Extruder Machine Production Workshop, highlighting the need for product improvement. To address this issue, an integrated approach combining Design for Assembly (DFA), Kano Models, and Design for Serviceability (DFS) is proposed.

Understanding the Problem Analysis

The primary problem faced by the pellet extruder machine production workshop is the delay in the assembly process due to the presence of raw material deposits. This not only affects the assembly process but also incurs significant costs. Therefore, an integrated approach is necessary to create effective solutions. Design for Assembly focuses on simplifying the assembly process by reducing the number of components needed. In this context, the Kano Model plays a crucial role in identifying product attributes that have the greatest impact on customer satisfaction. The Kano Model categorizes product attributes into three categories: basic attributes, performance attributes, and excitement attributes. By understanding these categories, designers can prioritize product attributes that have the greatest impact on customer satisfaction.

Approach Integration: Design for Assembly, Kano Model, and Design for Serviceability

Integrating Design for Assembly with the Kano Model and Design for Serviceability means not only paying attention to the ease of assembling products but also improving the product aspects after use. The proposed attributes for improvement design include reducing the number of components and improving the quality of the tool. By applying the one-dimensional (O) level in the Kano Model, we can find attributes that have a significant level of satisfaction and customer dissatisfaction. This confirms the importance of paying attention to all aspects of design, from the production process to daily use by customers. Design for Serviceability focuses on improving the product aspects after use, such as maintenance, repair, and replacement. By integrating Design for Serviceability with Design for Assembly and the Kano Model, designers can create products that are not only easy to assemble but also easy to maintain and repair.

Impact of Design Improvement

The results of this approach indicate that the design of the repair for the pellet extruder machine can reduce the assembly time and the costs incurred. By reducing the number of components, efficiency in product design increases, and this also has an impact on the reduction of the time needed for assembly. By optimizing service features and prioritizing user needs, not only customer satisfaction is increasing, but also overall product performance. The integration of Design for Assembly, Kano Model, and Design for Serviceability in product design provides significant benefits in terms of efficiency and effectiveness. For the pellet extruder machine industry, this approach can be a strategic step in overcoming existing problems and creating better products.

Conclusion

The integration between Design for Assembly, Kano Model, and Design for Serviceability in product design provides significant benefits in terms of efficiency and effectiveness. For the pellet extruder machine industry, this approach can be a strategic step in overcoming existing problems and creating better products. By designing products that are easier to assemble and improve after-sales services, companies can increase customer satisfaction while reducing operational costs. This approach is a clear proof that a good design is not only concerned with functions but also overall user experience.
