Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If grommets are newly developed and applied for each vehicle layout change, then the grommet can be perfectly matched to the specific vehicle layout, but investment costs and product development costs increase
Solution Approach 1:
The grommet is designed with a deformable part that can change its shape and length to adapt to different vehicle layouts. The hollow body part can be deformed to various configurations, allowing a single grommet design to serve multiple vehicle types and layouts, thereby eliminating the need for separate grommet developments for each vehicle model and reducing manufacturing costs.
Solution Approach 2:
The grommet incorporates a deformable part that can dynamically change its shape and dimensions. This dynamic characteristic allows the grommet to adapt to different installation requirements and vehicle layouts after manufacturing, providing versatility without requiring multiple fixed designs.
2Adaptability or versatility
If grommets are newly developed and applied for each vehicle layout change, then the grommet can be perfectly matched to the specific vehicle layout, but mold costs increase
Solution Approach 1:
A single mold can produce grommets with the deformable part structure, which then can be configured for different vehicle layouts. This universal mold design reduces the number of molds needed compared to traditional approaches requiring separate molds for each vehicle type.
Solution Approach 2:
The deformable part structure allows the grommet to achieve multiple configurations from a single molded piece, reducing mold complexity while maintaining adaptability to various layouts.
3Ease of manufacture
If a fixed-length grommet is used, then the manufacturing process is simple, but the grommet cannot be applied to various vehicle layouts
Solution Approach 1:
The grommet incorporates a deformable part that can change length and shape after manufacturing. This dynamic feature is integrated into the manufacturing process through a single mold that produces the deformable structure, maintaining manufacturing simplicity while enabling adaptability to various vehicle layouts.
Solution Approach 2:
The grommet's length and shape parameters can be changed by deforming the hollow body part after manufacturing. This allows a single manufacturing process to produce grommets that can subsequently be adjusted to different dimensions suitable for various vehicle layouts.
