Current sheet-like materials for moisture absorption and desorption in air-conditioning systems have insufficient moisture release rates and workability issues, particularly in high-humidity environments and during processing into complex structures like honeycombs.
Innovation Solution
A self-heating sheet-like material is developed with a laminate structure comprising a self-heating layer and an adsorption layer connected for heat conduction, using a metallic fiber sintered body with stainless steel fibers and an adhesion layer, which enables rapid moisture release and excellent workability in honeycomb or corrugated structures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional sheet-like materials for moisture absorption are used, then moisture absorption capacity is maintained, but moisture release rate is insufficient
Solution Approach 1:
The sheet-like material is divided into multiple layers with distinct functions: a hydrophobic layer for rapid moisture release and a hydrophilic layer for moisture absorption. This segmentation allows each layer to optimize its specific function, with the hydrophobic layer providing fast moisture release capability that resolves the contradiction between maintaining absorption capacity and improving release rate.
Solution Approach 2:
Different regions of the sheet-like material have different moisture release properties. The hydrophobic layer is positioned to provide rapid moisture release pathways, while the hydrophilic layer maintains absorption capacity. This local differentiation of material properties enables simultaneous optimization of both moisture absorption and release rates.
2Adaptability or versatility
If sheet-like material is processed into complex structures like honeycombs, then functionality is improved, but workability deteriorates
Solution Approach 1:
The sheet-like material exhibits dynamic mechanical properties that allow it to be easily formed into complex structures during manufacturing, then maintain structural integrity during use. The layered construction with hydrophobic and hydrophilic layers provides flexibility during forming operations while maintaining the necessary structural stability for honeycomb and corrugated configurations.
Solution Approach 2:
The combination of hydrophobic and hydrophilic layers creates a composite material structure that balances workability and structural integrity. The hydrophobic layer provides slip and flexibility during forming operations, while the hydrophilic layer maintains structural stability, enabling successful processing into complex honeycomb and corrugated structures.
