Laminated Insulation Composite with CFC Screws for Low Heat Loss
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing thermal insulation composites for high-temperature applications suffer from reduced insulating properties due to connecting elements that penetrate the material, leading to heat conduction and structural instability.
Innovation Solution
A composite using CFC screws with a core diameter of 6-10 mm and a specific thread design that displaces material upon insertion, minimizing heat loss and providing enhanced stability through secure engagement without protruding elements, allowing for easy replacement and re-bonding of layers.

Engineering Contradiction Analysis
1Stability of the object's composition
If connecting elements penetrate the insulating material to secure layers, then structural stability is improved, but heat conduction increases and insulating properties deteriorate
Solution Approach 1:
The harmful function of the connecting elements (heat conduction) is separated from the useful function (structural stability). The connecting elements are extracted from the insulating material by creating blind holes, so they only extend partway through the layers rather than penetrating completely. This removes the heat conduction path to the exterior while maintaining the mechanical connection between layers.
Solution Approach 2:
The connecting elements have different properties in different regions: they provide mechanical engagement (threads) in the local region where they contact the layers, but they do not extend through the entire structure. The blind hole configuration creates a local connection zone that provides stability without creating a continuous heat conduction path through the insulating material.
2Stability of the object's composition
If connecting elements protrude on both sides of the insulating material, then structural stability is improved, but dimensional stability deteriorates
Solution Approach 1:
The protruding portions of the connecting elements that cause dimensional instability are removed. By using blind holes instead of through-holes, the connecting elements are extracted from the exterior surfaces, eliminating the protrusions that compromise dimensional stability while retaining the structural connection function within the insulating material.
3Stability of the object's composition
If conventional connecting elements are used, then structural stability is improved, but ease of repair deteriorates
Solution Approach 1:
The connecting elements transform from a static, permanent fixation method to a dynamic, reversible system. The threaded blind holes allow connecting elements to be easily inserted and removed, enabling layers to be replaced or adjusted without permanent damage to the insulating material structure.
