Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If connector brackets are made from solid polymer structure, then production cost is reduced, but rigidity and stability are insufficient
Solution Approach 1:
The connector bracket employs a double-walled hollow structure with polymer material, creating an internal cavity that reduces material consumption and production cost while maintaining structural rigidity through the distributed wall configuration
Solution Approach 2:
The connector bracket combines polymer material with a double-walled structural configuration, creating a composite system where the hollow geometry enhances rigidity relative to solid material usage, achieving both cost reduction and mechanical performance
2Stability of the object's composition
If connector brackets are made with complex structure to increase rigidity, then stability is improved, but production cost increases
Solution Approach 1:
The double-walled hollow structure provides enhanced stability through geometric configuration rather than material complexity, using the cavity space to distribute stresses and improve rigidity without requiring complex external geometries or additional components
Solution Approach 2:
The double-walled structure utilizes the third dimension by creating an internal cavity, transforming a potentially complex surface geometry into a simpler volumetric configuration that achieves rigidity through spatial distribution rather than surface complexity
3Reliability
If supporting rails are made with complex cross-sectional shape to accommodate connector brackets, then connection stability is improved, but manufacturing complexity increases
Solution Approach 1:
Instead of making the supporting rail complex to accommodate the connector bracket, the invention inverts the approach by making the connector bracket complex (double-walled hollow structure) to accommodate a simple rail cross-section, thereby simplifying rail manufacturing while achieving stable connection
Solution Approach 2:
The complex structural features are extracted from the supporting rail and concentrated in the connector bracket, allowing the rail to maintain a simple cross-sectional shape for easy manufacturing while the bracket provides the necessary connection stability through its double-walled hollow configuration
