Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If a bridge part is provided to form a thermal barrier, then heat transfer is reduced, but mechanical bond strength and installation reliability deteriorate
Solution Approach 1:
The bridge part is made from a composite material consisting of a plastic matrix and fibrous reinforcement (e.g., glass fibers, carbon fibers, or basalt fibers). This composite structure provides both thermal insulation properties and enhanced mechanical strength, allowing the bridge part to simultaneously reduce heat transfer and maintain reliable mechanical bonding between the wall part and facade part.
Solution Approach 2:
The invention changes the material parameters of the bridge part by using fiber-reinforced plastic with specific fiber content (10-60% by weight), fiber length (5-50 mm), and fiber orientation (0-90 degrees relative to the longitudinal axis). These parameter adjustments optimize both thermal insulation performance and mechanical bond strength.
2Loss of energy
If a bridge part is provided to form a thermal barrier, then heat transfer is reduced, but mechanical strength deteriorates
Solution Approach 1:
The bridge part utilizes fiber-reinforced composite materials where the fibrous reinforcement (glass, carbon, or basalt fibers) provides tensile and flexural strength while the plastic matrix provides thermal insulation. This composite approach enables the bridge part to simultaneously achieve thermal barrier functionality and sufficient mechanical strength to withstand facade loads.
Solution Approach 2:
The invention implements local quality by orienting fibers in specific directions within the bridge part. Fibers can be oriented at 0-90 degrees relative to the longitudinal axis, with higher fiber concentration and different orientation patterns in regions experiencing different stress levels, thereby optimizing mechanical strength where needed while maintaining thermal insulation throughout.
3Ease of manufacture
If conventional materials are used for the bridge part, then production is simpler, but mechanical and thermal properties are insufficient
Solution Approach 1:
The invention employs fiber-reinforced plastic composite materials that can be processed using conventional injection molding techniques. The composite pellets are fed into standard injection molding machines, and the bridge part is formed in a single-shot process, maintaining production simplicity while achieving superior mechanical and thermal properties compared to conventional homogeneous plastics.
Solution Approach 2:
The invention optimizes manufacturing parameters including fiber content (10-60% by weight), fiber length (5-50 mm), injection temperature, and mold design to ensure proper fiber distribution and orientation during injection molding. These parameter adjustments enable the production of fiber-reinforced bridge parts with consistent quality using conventional manufacturing equipment.
