Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If thermosetting matrix materials are used for fiber-reinforced connecting rods, then manufacturing precision and structural stability are improved, but impact resistance deteriorates
Solution Approach 1:
The patent employs a composite structure combining thermoplastic matrix material with continuous fiber reinforcing filaments. This composite approach allows the material to exhibit both the manufacturing precision and structural stability of thermosetting materials and the impact resistance of thermoplastic materials, resolving the contradiction between these two properties.
2Stability of the object's composition
If thermosetting matrix materials are used for fiber-reinforced profiles, then structural stability is improved, but adaptability deteriorates due to inability to reshaping
Solution Approach 1:
The patent utilizes the thermoplastic matrix material's ability to change state through temperature parameter changes, allowing the structure to be reshaped and adapted to different configurations after manufacturing. This provides both structural stability during operation and adaptability for modification, resolving the contradiction between stability and adaptability.
3Reliability
If thermoplastic matrix materials are used for fiber-reinforced structures, then impact resistance is improved, but production cost increases
Solution Approach 1:
The patent uses a composite material system where the thermoplastic matrix provides impact resistance while the continuous fiber reinforcing filaments provide structural strength. This composite approach achieves the desired mechanical properties without requiring expensive specialized thermoplastic materials alone, thereby controlling production costs while maintaining impact resistance.
4Stability of the object's composition
If thermosetting matrix materials are used for fiber-reinforced profiles, then structural stability is improved, but adaptability deteriorates due to limited profile geometry
Solution Approach 1:
The patent leverages the thermoplastic matrix material's property changes with temperature to enable complex profile geometries and shape modifications. This allows for greater design flexibility and adaptability in profile geometry while maintaining structural stability during service, resolving the contradiction between stability and geometric flexibility.
