Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If a multi-layer heat insulation assembly is used, then heat insulation performance is improved, but formation efficiency is reduced and thickness becomes uneven
Solution Approach 1:
The heat insulation assembly is divided into multiple layers (first heat insulation layer and second heat insulation layer) with different materials and functions. The first layer uses aerogel for high-temperature resistance while the second layer uses foam material for general heat insulation, allowing each layer to be optimized independently for its specific function while maintaining overall formation efficiency
Solution Approach 2:
The patent combines different materials (aerogel and foam material) in a composite heat insulation assembly. Each material is selected for its specific properties - aerogel for high-temperature zones and foam material for lower-temperature zones - creating a composite structure that achieves both excellent heat insulation performance and efficient formation
2Loss of energy
If multi-layer heat insulation is implemented, then heat insulation performance is improved, but thickness uniformity deteriorates
Solution Approach 1:
Different regions of the heat insulation assembly use different materials with appropriate thicknesses. The first heat insulation layer (aerogel) is positioned where high-temperature resistance is needed, while the second heat insulation layer (foam material) is positioned for general insulation, allowing each region to have optimal local properties without compromising overall thickness uniformity
Solution Approach 2:
By segmenting the heat insulation into distinct layers with different materials, the patent allows independent optimization of each layer's thickness and properties. This segmentation prevents thickness uniformity issues that would arise from using a single material throughout, as each layer can be manufactured to its optimal thickness
3Ease of manufacture
If existing heat insulation materials are used, then ease of manufacture is maintained, but heat resistance temperature is insufficient
Solution Approach 1:
The patent employs a composite material structure where aerogel is used in the first heat insulation layer for high-temperature resistance and foam material is used in the second layer for general insulation. This composite approach maintains ease of manufacture by using readily available materials while significantly improving heat resistance temperature performance
Solution Approach 2:
The patent changes the material parameters (thermal conductivity, heat resistance temperature) by selecting aerogel with superior heat resistance properties for the first layer. This parameter change enables the system to withstand higher temperatures while maintaining ease of manufacture through standard manufacturing processes

Function Achieved in This Case
The dual-layer heat insulation assembly ensures even thickness and stable formation, preventing overheating and reducing energy consumption while maintaining a comfortable user experience.
Implementation Method 1
a heat insulation assembly arranged on a periphery of the heating assembly and including a first heat insulation layer and a second heat insulation layer
Implementation Method 2
the first heat insulation layer includes a first aerogel, and the second heat insulation layer includes a second aerogel; and a fire retardant in the first aerogel is different from a fire retardant in the second aerogel, so as to enable a heat-resistance temperature of the first heat insulation layer to be higher than a heat-resistance temperature of the second heat insulation layer
