Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If traditional thermally insulating materials are used in facade attachment systems, then thermal insulation performance is improved, but fire resistance deteriorates
Solution Approach 1:
The invention uses a composite material consisting of glass fiber reinforced plastic (GFRP) for the spacer plate and aluminum alloy for the angle bracket. The GFRP provides both thermal insulation properties and fire resistance, while the aluminum alloy contributes to structural strength. This composite construction resolves the contradiction by combining materials that individually have complementary properties to achieve both good thermal insulation and fire resistance simultaneously.
2Reliability
If fireproof materials are used in facade attachment systems, then fire resistance is improved, but thermal insulation performance deteriorates
Solution Approach 1:
The GFRP material serves dual purposes: it provides fire resistance comparable to traditional fireproof materials while simultaneously offering thermal insulation properties that metal materials cannot provide. The glass fiber reinforcement maintains structural integrity at high temperatures, while the plastic matrix provides thermal insulation, thus resolving the contradiction between fire resistance and thermal insulation performance.
3Strength
If metal materials are used for angle bracket and spacer plate, then structural strength is improved, but thermal insulation performance deteriorates
Solution Approach 1:
The invention replaces the traditionally all-metal construction (metal angle bracket + metal spacer plate) with a composite construction (aluminum alloy angle bracket + GFRP spacer plate). The aluminum alloy angle bracket maintains structural strength and load-bearing capacity, while the GFRP spacer plate provides both structural support and thermal insulation, thus resolving the contradiction between structural strength and thermal insulation performance.
