Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing insulating materials for surface temperature control devices, such as underfloor heating, do not provide a secure fastening mechanism for temperature-controlled lines due to their fiber structure, leading to instability and potential fire hazards.
Innovation Solution
A fire-retardant and non-combustible insulating board with a glass fiber fabric or glass fiber fabric cover layer, combined with an aluminum foil and a protective layer, which securely holds fastening elements and prevents moisture penetration, ensuring stable and safe attachment of temperature-controlled lines.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If fibrous insulating material is used for thermal and sound insulation, then insulation performance is improved, but fastening capability deteriorates
Solution Approach 1:
The patent applies composite materials by combining fibrous insulating material with a separate covering layer that has fastening capability. The covering layer is made of materials suitable for securing fastening elements, while the underlying fibrous material provides thermal and sound insulation. This composite structure allows both insulation performance and fastening capability to coexist without compromising either function.
2Strength
If conventional covering layers are used, then fastening capability is improved, but fire resistance deteriorates
Solution Approach 1:
The patent changes the material parameters of the covering layer by specifying that it must be made of fire-retardant or non-combustible materials. This parameter change ensures that the covering layer maintains fastening capability while simultaneously providing fire resistance, thereby eliminating the contradiction between these two requirements.
3Strength
If barbed fastening elements are driven through the cover layer, then fastening capability is improved, but moisture protection deteriorates
Solution Approach 1:
The patent applies local quality by allowing the covering layer to have different properties in different locations. The material is designed to be penetrable by fastening elements where needed, while maintaining moisture protection in other areas. The covering layer's composition and structure are optimized to provide both fastening capability and moisture resistance simultaneously.
