Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If steel reinforcements are used for seismic reinforcement, then structural resistance is improved, but weight increases and aesthetic integration deteriorates
Solution Approach 1:
The patent uses composite materials consisting of flax fiber reinforced with biodegradable polymer matrix to replace steel reinforcements. This composite material provides comparable structural resistance while significantly reducing weight and improving aesthetic integration with wooden constructions.
2Strength
If steel reinforcements are used for seismic reinforcement, then structural resistance is improved, but aesthetic integration deteriorates
Solution Approach 1:
The patent employs flax fiber composite materials that can be shaped and finished to match the aesthetic characteristics of wooden constructions, eliminating the visual disparity between metal reinforcements and wooden structure while maintaining structural resistance.
3Weight of moving object
If composite material reinforcements are used, then weight is reduced, but environmental impact increases due to matrix and reinforcement production
Solution Approach 1:
The patent changes the material parameters by using flax fiber instead of traditional synthetic fibers and biodegradable polymer matrix instead of conventional petroleum-based resins. This parameter change reduces environmental impact while maintaining the weight advantage of composite materials.
Solution Approach 2:
The patent develops a composite material system using flax fiber and biodegradable polymer that combines the weight benefits of composites with reduced environmental impact through natural fiber and eco-friendly matrix selection.
4Weight of moving object
If composite material reinforcements are used, then weight is reduced, but recyclability deteriorates
Solution Approach 1:
The patent designs the composite reinforcement system to enable separation and recovery of flax fiber and polymer matrix components at end-of-life, facilitating recycling and reducing waste. The layered composite structure allows for systematic disassembly and material recovery.
