Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If separate components (sheet-like acoustic insulation member, apparatus, transmission member) are installed individually into the vehicle body, then each component can be independently selected and installed, but the incorporation process becomes complex and time-consuming
Solution Approach 1:
The patent combines the sheet-like acoustic insulation member, apparatus, and transmission member into a single integrated assembly. The transmission member is embedded within the acoustic insulation member, and the apparatus is mounted on the acoustic insulation member, creating a unified structure that simplifies installation while maintaining independent functionality of each component.
Solution Approach 2:
The acoustic insulation member serves multiple functions simultaneously: it provides acoustic insulation, supports the apparatus, and contains the embedded transmission member. This multi-functional design eliminates the need for separate installation processes for each component, reducing overall complexity.
2Productivity
If multiple separate components are installed into the vehicle body, then each component can be optimized independently, but the installation time and labor increase
Solution Approach 1:
The transmission member is pre-embedded into the acoustic insulation member during manufacturing, and the apparatus is pre-mounted on the acoustic insulation member. This preliminary assembly eliminates the need for time-consuming on-site installation of each component separately, significantly reducing incorporation time.
Solution Approach 2:
By combining multiple components into a single pre-assembled unit, the patent enables installation as one integrated component rather than multiple separate operations, directly improving productivity and reducing labor time.
3Ease of manufacture
If the transmission member is routed separately from the acoustic insulation member, then electrical connections can be made independently, but the overall assembly process becomes more difficult
Solution Approach 1:
The transmission member is nested within the acoustic insulation member, with the transmission member embedded in the sheet structure. This nesting arrangement simplifies assembly by integrating the electrical connection pathway within the insulation structure itself, eliminating separate routing operations.
