Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional building materials (steel, concrete, wood) are used, then structural strength and stability are achieved, but maintenance costs increase and susceptibility to environmental damage occurs
Solution Approach 1:
The patent employs fiberglass reinforced polymer (FRP) composite materials to replace traditional building materials. These composites combine glass fibers with polymer matrices to achieve superior strength-to-weight ratios, corrosion resistance, and durability while eliminating the maintenance issues associated with steel, concrete, and wood structures.
Solution Approach 2:
The invention changes the material parameters by transitioning from metallic and organic materials to polymer-based composites. This parameter change provides resistance to environmental factors such as moisture, insects, and corrosion, thereby reducing maintenance costs while maintaining structural reliability.
2Strength
If traditional building materials are used, then structural strength is achieved, but weight increases leading to higher transportation and installation costs
Solution Approach 1:
The patent utilizes FRP composite materials that provide high structural strength through the reinforcement of glass fibers within the polymer matrix. This composite structure achieves comparable or superior strength to traditional materials while significantly reducing weight, thereby lowering transportation and installation costs.
Solution Approach 2:
The invention changes the density and strength parameters by adopting polymer-based composites instead of metallic materials. The glass fiber reinforcement provides necessary structural strength while the polymer matrix keeps the overall density low, achieving an optimal strength-to-weight ratio that reduces transportation and installation expenses.
3Productivity
If new building materials like PFRP are used, then construction costs and installation time are reduced, but compliance with building codes and engineering standards becomes challenging
Solution Approach 1:
The patent applies preliminary action by pre-engineering and pre-certifying PFRP building systems to meet building codes and engineering standards before deployment. The systems are designed with integrated fire protection, thermal insulation, and structural components that are预先 validated to comply with regulations, enabling rapid installation without compromising code compliance.
Solution Approach 2:
The invention employs multi-functional PFRP components that integrate multiple building requirements into single elements. For example, wall panels combine structural support, fire resistance, thermal insulation, and weather protection, allowing fast installation while meeting various building code requirements simultaneously.
4Temperature
If traditional building materials are used, then fire protection and thermal efficiency standards are met, but energy efficiency and sustainability requirements are not achieved
Solution Approach 1:
The patent employs FRP composite materials with integrated thermal insulation properties. The polymer matrix and air pockets within the composite structure provide excellent thermal insulation, reducing heat transfer and improving energy efficiency while meeting fire protection standards through fire-retardant formulations.
Solution Approach 2:
The invention changes the thermal conductivity parameter by using polymer-based composites with inherently lower thermal conductivity compared to metallic materials. Additionally, the composite structure incorporates air pockets and insulating layers that further reduce heat transfer, achieving superior energy efficiency and sustainability performance.

Implementation Method 1
Pultrusion is a manufacturing process for producing continuous lengths of PFRP structural shapes with constant cross-sections. The process involves pulling these raw materials (rather than pushing, as is the case in extrusion) through a heated steel die using a continuous pulling device.
Implementation Method 2
The process involves pulling these raw materials (rather than pushing, as is the case in extrusion) through a heated steel die using a continuous pulling device. This technique removes all air/gasses from the product
