Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional smooth pad surface is used, then the pad is easy to manufacture and clean, but the loading target part can move bidirectionally during transportation
Solution Approach 1:
The pad surface is segmented into multiple flow prevention patterns (protrusions) arranged in a grid pattern. Each protrusion creates individual flow barriers that collectively prevent bidirectional movement of the loading target part, transforming a smooth surface into a segmented anti-slip structure.
Solution Approach 2:
The pad incorporates localized protrusions with specific dimensions (height of 0.15-0.25mm, width of 3-5mm, spacing of 3-5mm) at strategic positions on the surface. These localized features create asymmetric flow resistance that prevents movement in both directions while maintaining overall pad simplicity.
2Reliability
If the loading target part is securely held, then movement is prevented, but the part becomes difficult to detach
Solution Approach 1:
The protrusions are designed with specific height (0.15-0.25mm) and spacing (3-5mm) parameters that create dynamic interaction with the loading target part. During normal transport, the geometry provides sufficient friction to prevent movement, but during intentional detachment, the part can be easily removed without permanent adhesion.
Solution Approach 2:
The pad uses controlled parameters for protrusion dimensions (height, width, spacing) that optimize the balance between holding strength and detachment ease. The specific parameter ranges ensure adequate friction for security while allowing simple removal when needed.
3Reliability
If the tray module is designed for secure transport, then movement prevention is improved, but the manufacturing process becomes more complex
Solution Approach 1:
The manufacturing process is segmented into forming the base pad and then adding the protrusion patterns. This segmentation allows the use of standard pad manufacturing methods while incorporating the anti-slip features through additional processing steps that create the flow prevention patterns.
Solution Approach 2:
The protrusions are created as localized features on the pad surface with specific dimensions. This local quality approach allows the majority of the pad to be manufactured using conventional methods, while only the surface patterns require additional processing, minimizing overall manufacturing complexity.
