Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional cobbles are made from mortar, ceramic, or concrete, then they achieve sufficient structural strength, but they become heavy and difficult to replace
Solution Approach 1:
The cobble is divided into two separable pieces: an inner block made from recycled polymer waste and a coating cover that encapsulates it. This segmentation allows the heavy conventional materials to be replaced with lighter polymer materials while maintaining structural integrity through the combined design of the two components.
Solution Approach 2:
The invention uses composite construction by combining recycled polymer material for the inner block with a coating cover, creating a composite structure that achieves sufficient strength while reducing weight compared to conventional monolithic mortar, ceramic, or concrete cobbles.
2Strength
If conventional cobbles are made as single-piece structures, then they achieve structural integrity, but they become difficult to repair or replace when damaged
Solution Approach 1:
By dividing the cobble into separable inner block and coating cover components, the invention enables easy replacement of only the damaged part. The embedding system with tabs and holes allows the pieces to be assembled and disassembled readily, facilitating repair without replacing the entire cobble structure.
Solution Approach 2:
The cobble structure transitions from a static single-piece design to a dynamic separable design, where the inner block and coating cover can be independently replaced. This dynamic characteristic allows the structure to adapt to repair needs while maintaining structural integrity during use.
3Object-affected harmful factors
If polymeric waste is accumulated in landfills, then it causes environmental pollution, but recycling it requires complex processing
Solution Approach 1:
The invention changes the physical state and properties of recycled polymer waste by using compression molding to transform mixed polymeric waste into a compact, homogeneous inner block. This parameter change allows diverse polymer waste to be converted into a usable construction material without complex sorting or processing.
Solution Approach 2:
The invention converts harmful polymeric waste that would otherwise pollute the environment into a beneficial construction material. By incorporating mixed polymer waste into the inner block structure, the invention transforms an environmental problem into a resource for sustainable construction.
4Ease of manufacture
If cobbles are made with uniform material throughout, then they achieve simplicity in manufacturing, but they lack customization options for aesthetics and functionality
Solution Approach 1:
By separating the cobble into inner block and coating cover, the invention allows independent customization of each component. The inner block can be manufactured with uniform recycled polymer material for simplicity, while the coating cover can be customized with different colors, textures, and properties to meet aesthetic and functional requirements.
Solution Approach 2:
The coating cover can have different properties in different areas or layers, allowing local customization for specific aesthetic or functional requirements while the inner block maintains uniform construction for manufacturing simplicity. This local quality differentiation enables versatility without compromising ease of manufacture.
