Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If fossil-based materials and conventional manufacturing processes are used, then structural strength and durability are achieved, but environmental impact and greenhouse gas emissions increase
Solution Approach 1:
The patent employs composite materials consisting of recycled sand particles combined with binding agents to create construction components that maintain structural strength while reducing environmental impact. The composite structure integrates different material properties to achieve both mechanical performance and sustainability goals
Solution Approach 2:
The invention recovers and reuses sand particles from demolished structures and construction waste, transforming discarded materials into valuable construction resources. This circular approach reduces the need for virgin materials and minimizes waste sent to landfills
2Use of energy by stationary object
If conventional manufacturing processes are used, then production efficiency is maintained, but energy consumption and water usage increase
Solution Approach 1:
The patent modifies manufacturing parameters by using low-energy mixing and curing processes for the sand-based composites. The composition and curing conditions are optimized to achieve adequate material strength without requiring excessive energy input or prolonged processing times
3Loss of substance
If recycled sand composition is used, then sustainability is improved, but material consistency and manufacturing precision may deteriorate
Solution Approach 1:
The patent applies different binding agents and additives to specific regions or batches of recycled sand based on their particle characteristics. This localized adjustment ensures that variations in recycled material properties do not compromise the overall dimensional accuracy and quality of the final product
