Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If wood-based materials are used for building structures, then cost-effectiveness and workability are improved, but fire resistance deteriorates
Solution Approach 1:
The patent applies composite materials by combining wood shavings with cement and calcium chloride to create a new material that retains the workability of wood while achieving fire resistance through the cement-based composition
Solution Approach 2:
The patent changes the chemical composition parameters by incorporating calcium chloride and cement into the wood shavings, fundamentally altering the material's fire properties while maintaining manufacturing ease
2Object-affected harmful factors
If composite materials are used to achieve fire safety, then fire resistance is improved, but toxicity worsens
Solution Approach 1:
The patent uses natural, biodegradable materials like wood shavings and calcium chloride that decompose safely rather than producing toxic gases, replacing synthetic fire-resistant materials
Solution Approach 2:
The calcium chloride and cement create a chemically stable environment that prevents toxic chemical reactions during combustion, producing inert or benign decomposition products
3Object-affected harmful factors
If composite materials are used to achieve fire resistance, then fire safety is improved, but cost worsens
Solution Approach 1:
The patent employs inexpensive materials including wood shavings (a byproduct), cement, and calcium chloride to achieve fire resistance at low cost, avoiding expensive specialized fire-resistant materials
Solution Approach 2:
The patent utilizes wood shavings, a waste byproduct from lumber production, transforming discarded material into a valuable fire-resistant building component
4Object-affected harmful factors
If wood shavings are mixed with cement and calcium chloride, then fire resistance is improved, but shrinkage and cracking worsen
Solution Approach 1:
The patent optimizes the mix ratio parameters of wood shavings, cement, and calcium chloride to achieve a balance between fire resistance and dimensional stability, preventing shrinkage and cracking through proper composition control
