Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If complex sealing structures are used to achieve flush/smooth sealing, then sealing performance is improved, but device complexity and manufacturing difficulty increase
Solution Approach 1:
The sealing profile is divided into distinct functional segments: a hook figure portion for lateral (x-direction) fixation, a pillar portion for vertical positioning, and a sealing portion for dust and liquid prevention. This segmentation allows each component to perform its specific function efficiently without requiring an overly complex integrated structure.
Solution Approach 2:
The hook figure and pillar structures are integrated within the sealing profile cross-section, with the hook figure forming part of the profile body and the pillar portion extending from it. This nested arrangement achieves multiple sealing and fixation functions within a unified structure, reducing overall complexity while maintaining effective sealing performance.
2Reliability
If complex sealing structures are used to achieve flush/smooth sealing, then sealing performance is improved, but manufacturing cost and production difficulty increase
Solution Approach 1:
The invention combines the hook figure for lateral fixation, the pillar for vertical positioning, and the sealing elements into a single integrated sealing profile that can be produced as one piece. This merging of functions into a unified component simplifies manufacturing processes, reduces assembly steps, and lowers production costs while maintaining effective sealing performance.
Solution Approach 2:
The sealing profile serves multiple functions simultaneously: the hook figure provides x-direction fixation, the pillar provides positioning, and the integrated structure provides sealing against dust and liquids. This multi-functionality eliminates the need for separate components, simplifying both manufacturing and assembly processes.
3Stability of the object's composition
If traditional sealing structures are used, then glass fixation is achieved, but flush/smooth surface form cannot be established
Solution Approach 1:
The sealing profile applies different structural characteristics at different locations: the hook figure provides lateral restraint for fixation stability, while the external flush lip creates a smooth outer surface. This local differentiation of structural quality allows simultaneous achievement of glass fixation and flush surface form without compromising either function.
