Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional PVC side enclosing strip is used, then manufacturing simplicity is maintained, but tensile strength and elasticity are insufficient leading to deformation and misalignment
Solution Approach 1:
The side enclosing strip is constructed as a composite material combining PVC coating layer with a mesh layer containing inclined warp and weft yarns. This composite structure provides both the flexibility of PVC and the tensile strength of the mesh framework, resolving the contradiction between maintaining manufacturing simplicity and achieving sufficient tensile strength.
Solution Approach 2:
The invention changes the structural parameters of the side enclosing strip by introducing inclined yarns at specific angles (30°-60°) relative to the longitudinal direction. This parameter change enables the strip to achieve both strength and elasticity without requiring complex multi-component assemblies, thus resolving the contradiction between strength improvement and structural complexity.
2Strength
If conventional PVC side enclosing strip is used, then material simplicity is maintained, but elasticity is limited causing buckling and gapping at corners
Solution Approach 1:
The mesh layer with inclined warp and weft yarns forms a composite elastic structure that works synergistically with the PVC coating. The inclined yarn arrangement provides elasticity and conformability to curved surfaces, while the PVC layer provides structural integrity, resolving the contradiction between achieving elasticity and avoiding excessive structural complexity.
Solution Approach 2:
The inclined yarn arrangement at 30°-60° angles enables the side enclosing strip to naturally conform to curved contours and tapered ends of the board body. This curvature-adaptive design eliminates buckling and gapping at corners without requiring complex adjustment mechanisms, thus resolving the contradiction between elasticity improvement and structural simplicity.
3Shape
If manual stretching and positioning is performed, then strip conformability is improved, but production time increases and productivity decreases
Solution Approach 1:
The side enclosing strip is pre-formed with inclined yarns and appropriate dimensions before assembly. This preliminary preparation enables the strip to automatically conform to the board body contours during assembly without requiring extensive manual stretching and positioning, thus improving conformability while maintaining high production speed.
Solution Approach 2:
The inclined yarn arrangement and optimized strip dimensions are designed to match the curvature parameters of the board body. This parameter matching allows the strip to self-conform during assembly, eliminating the need for time-consuming manual adjustment and thereby resolving the contradiction between improved conformability and maintained productivity.
4Manufacturing precision
If conventional strip with poor conformability is used, then manufacturing simplicity is maintained, but adhesion quality deteriorates due to misalignment and uneven adhesive distribution
Solution Approach 1:
The composite structure of PVC coating combined with mesh layer provides both structural stability and surface conformability. This enables uniform adhesive distribution and reliable bonding to the board body, resolving the contradiction between improved adhesion quality and avoided excessive design complexity.
Solution Approach 2:
The side enclosing strip is pre-formed with precise dimensions and inclined yarn arrangement that match the board body contours. This preliminary precision ensures proper alignment and uniform adhesive distribution during assembly, achieving high manufacturing precision without requiring complex adjustment devices or procedures.

The solution allows for seamless wrapping around curved contours, reduces stress concentration, and enhances the board's structural integrity, ensuring consistent quality and durability under dynamic loads.
Implementation Method 1
a mesh layer of the side sealing strip comprises inclined warp yarns and weft yarns, so that biaxial stretch and mechanical elasticity is introduced to the side sealing strip
Implementation Method 2
The angled orientation of the two connecting threads of the present invention resists horizontal shearing and torsion. The triangle inherently provides geometric bracing, making the board more rigid under lateral stress
