Aerogel Composite Insulation Sheet for Low-Dust Thermal Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current thermal insulation materials for electronic devices are inadequate due to poor adhesion between fibers and aerogel, leading to dust generation, mechanical weakness, and reduced durability, which can cause equipment damage and heat-related failures.
Innovation Solution
A composite thermal insulation sheet is developed with a sol-impermeable coating layer on one surface and functional layers on the other, using a sol and catalyst to form an aerogel sheet, enhancing mechanical strength and reducing dust generation while maintaining high thermal insulation efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If aerogel is used as a thermal insulation material, then thermal insulation performance is improved, but mechanical strength deteriorates
Solution Approach 1:
The patent combines aerogel particles with a fiber sheet to create a composite thermal insulation sheet. The fiber sheet provides mechanical strength while the aerogel particles provide thermal insulation performance, resolving the contradiction between these two properties.
2Reliability
If aerogel particles are used in processing, then thermal insulation performance is improved, but dust generation increases
Solution Approach 1:
The patent uses a fiber sheet as a flexible matrix that holds and contains the aerogel particles. This fiber sheet structure prevents aerogel particles from becoming loose and generating dust during processing, while still allowing the aerogel to provide thermal insulation performance.
3Reliability
If aerogel composite is used for thermal insulation, then thermal insulation performance is improved, but processing convenience deteriorates
Solution Approach 1:
The fiber sheet component of the composite provides flexibility and processability, making the aerogel-based thermal insulation material easier to handle and install in electronic devices, while the aerogel particles maintain the high thermal insulation performance.
