Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a sealing member is provided to easily open and close the dust collecting device, then the ease of operation is improved, but the sealing effect deteriorates causing dust leakage
Solution Approach 1:
The sealing member is divided into multiple sealing portions (first sealing portion, second sealing portion, third sealing portion) that contact different surfaces. This segmentation allows each portion to contribute to the sealing effect independently, maintaining reliable sealing while enabling easy operation through coordinated deformation of multiple segments.
Solution Approach 2:
The sealing member is designed to dynamically change its shape and position based on operational state. During normal operation, it deforms to contact sealing surfaces; during opening/closing, it can be pulled back. This dynamic behavior resolves the contradiction between maintaining strong sealing and enabling easy operation.
2Reliability
If a sealing member is provided to maintain sealing state under external shocks, then the reliability is improved, but the device complexity increases
Solution Approach 1:
The sealing member is designed as a flexible elastic body that can deform under external shocks to maintain contact with sealing surfaces. This flexibility allows it to adapt to shock forces without requiring complex mechanical shock-absorbing mechanisms, thus improving reliability while minimizing added complexity.
Solution Approach 2:
The sealing member automatically adjusts its shape and position in response to external shocks through its elastic properties, maintaining sealing without requiring external control systems or complex mechanisms. This self-adjusting capability improves reliability while avoiding additional device complexity.
3Reliability
If the sealing member extends from inner surface to coupling surface, then the sealing effect is improved, but the ease of operation deteriorates
Solution Approach 1:
The sealing member extending from the inner surface to the coupling surface is divided into multiple sealing portions, each contacting different surfaces. This segmentation allows the sealing function to be distributed across multiple contact points, maintaining strong sealing while enabling easier operation through coordinated deformation of segments.
Solution Approach 2:
The sealing member is designed to dynamically adjust its shape and position. During operation, it extends to contact both the inner surface and coupling surface for strong sealing. During opening/closing, it can be pulled back or deformed to reduce contact resistance, resolving the contradiction between extended sealing coverage and ease of operation.
