Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional thermal insulation materials, particularly those using resin foamed bodies, face challenges in achieving effective thermal insulation performance while maintaining a reduced thickness, and those used in cryogenic techniques require further enhancement in insulation performance without increasing thickness.
Innovation Solution
An aerogel laminate is developed by laminating an aerogel layer with a support having heat ray reflective or absorbing functions, where the aerogel layer is derived from polysiloxane or silica particles, enabling reduced thickness and enhanced thermal insulation properties.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a resin foamed body is used as a thermal insulation material, then the material structure is simple and easy to manufacture, but the thickness must be increased to achieve good thermal insulation performance
Solution Approach 1:
The patent combines aerogel particles (providing exceptional thermal insulation) with a resin matrix (providing structural support and ease of manufacture). This composite structure allows the material to achieve high thermal insulation performance in a thin layer while maintaining manufacturability through conventional composite material processing techniques.
Solution Approach 2:
The patent utilizes aerogel particles which are highly porous materials with extremely low thermal conductivity. The porous structure of aerogel provides superior thermal insulation performance per unit thickness, resolving the contradiction between achieving good insulation and reducing thickness.
2Length of stationary object
If the thickness of thermal insulation material is reduced, then the space for disposing insulation material is reduced and handling is easier, but thermal insulation performance deteriorates
Solution Approach 1:
By creating a composite material combining aerogel particles with resin, the patent achieves high thermal insulation performance in a thin configuration. The aerogel particles provide exceptional insulation properties that compensate for the reduced thickness, while the resin matrix maintains structural integrity.
Solution Approach 2:
The patent changes the material composition parameters by incorporating aerogel particles with specific properties (extremely low thermal conductivity, high porosity) into the insulation material, thereby achieving superior thermal insulation performance at reduced thickness.
3Ease of operation
If conventional thermal insulation materials are used in cryogenic applications, then the material is simple to handle, but thermal insulation performance is insufficient for enhanced energy saving requirements
Solution Approach 1:
The patent develops a composite material combining aerogel particles with resin matrix that provides enhanced thermal insulation performance suitable for cryogenic applications. The composite structure maintains ease of handling while achieving the superior insulation performance required for energy saving in cryogenic environments.
