Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing facade construction systems are either thermally insulating but not fire-resistant, or fire-resistant but offer little thermal insulation.
Innovation Solution
A thermally insulating bracket comprising a foot section with a base and a spacer plate holder, where the spacer plate is made of a laminate material consisting of muscovite mica paper layers bonded with silicone resin, providing both thermal insulation and fire resistance, and can be easily adapted to different distances and facade systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a thermally insulating material is used for the spacer plate, then thermal insulation performance is improved, but fire resistance deteriorates
Solution Approach 1:
The spacer plate is constructed as a composite material consisting of multiple layers: an outer layer of fire-resistant mineral wool, an inner layer of thermally insulating foam material, and a bonding layer of fire-resistant adhesive. This composite structure combines the fire resistance of mineral wool with the thermal insulation properties of foam, resolving the contradiction between thermal insulation and fire resistance.
2Reliability
If a fire-resistant material is used for the spacer plate, then fire resistance is improved, but thermal insulation performance deteriorates
Solution Approach 1:
The spacer plate uses a composite construction where mineral wool provides fire resistance and thermal insulation, foam material provides additional thermal insulation, and fire-resistant adhesive bonds the layers. This composite approach ensures both fire resistance and thermal insulation performance simultaneously.
3Strength
If the bracket is designed for high mechanical strength, then mechanical resilience is improved, but device complexity increases
Solution Approach 1:
The bracket integrates multiple functions into a single unified structure: the spacer plate serves as both thermal insulation and fire protection, while the bonding layer simultaneously adheres the insulation layers and provides fire resistance. This merging of functions reduces the number of separate components needed, thereby reducing overall device complexity while maintaining mechanical strength.
Applied Scientific Principles
