Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional barrier-wall structures are constructed using conventional materials and methods, then structural integrity and border security are achieved, but construction costs become prohibitively high
Solution Approach 1:
The patent changes the material parameters by using processed municipal solid waste as fill material instead of conventional compacted soil or gravel. The waste material is processed to achieve specific density ranges (115-130 pounds per cubic foot) and friction angles (20-34 degrees) that meet structural requirements while significantly reducing material costs.
Solution Approach 2:
The patent creates a composite fill material by combining processed municipal solid waste with geosynthetic reinforcement grids and stabilizing additives. This composite structure maintains the structural integrity needed for border walls while utilizing low-cost waste materials, thereby reducing overall construction costs without compromising reliability.
2Productivity
If municipal solid waste is disposed of in traditional landfills, then waste removal is achieved, but landfill space becomes scarce and disposal costs increase
Solution Approach 1:
The patent converts municipal solid waste, which is typically a harmful burden requiring expensive landfill disposal, into a beneficial structural fill material. By processing the waste to achieve appropriate density and stability characteristics, and reinforcing it with geosynthetic grids, the waste becomes a valuable resource that reduces both landfill需求的 and construction material costs.
Solution Approach 2:
The patent gives municipal solid waste a new function beyond disposal - it becomes a structural engineering material suitable for use as backfill in barrier walls. This multi-functional utilization transforms waste from a problem requiring space-consuming disposal into a resource that can contribute to infrastructure construction, thereby addressing both waste management and construction material needs simultaneously.
3Ease of manufacture
If processed solid waste is used as fill-material in barrier-wall structures, then construction costs are reduced and waste management is improved, but the stability and reliability of the wall structure may be compromised
Solution Approach 1:
The patent introduces geosynthetic reinforcement grids as an intermediary element between the processed waste fill material and the retaining walls. These grids provide tensile strength and structural stability to the waste material, ensuring that the barrier wall meets reliability requirements while maintaining the cost benefits of using processed waste as fill.
Solution Approach 2:
The patent carefully controls the physical parameters of the processed waste material, specifically targeting density ranges of 115-130 pounds per cubic foot and friction angles of 20-34 degrees. By optimizing these parameters and combining them with geosynthetic reinforcement, the waste material achieves the structural stability necessary for reliable barrier wall construction.
