Dehumidifying element, dehumidifying device, and a method of manufacturing dehumidifying element
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Dehumidifying elements with layered bodies experience expansion issues when adsorbents absorb moisture, leading to potential breakage due to excessive load from the casing, as the adsorbent expands more easily in the stacking direction than in the direction parallel to the sheets.
Innovation Solution
Incorporating a cushioning member between the casing and the layered body in the stacking direction to absorb and distribute the expansion force, reducing the pressure on the casing and minimizing the risk of breakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the layered body is fitted into the casing and fixed, then the outer shape is fixed and structural stability is improved, but the load applied to the layered body in the stacking direction increases and breakage probability increases
Solution Approach 1:
A cushioning member is introduced as an intermediary element between the casing and the layered body. This cushioning member absorbs and distributes the expansion force when the adsorbent expands, reducing the direct load on the layered body while maintaining the structural stability provided by the casing.
Solution Approach 2:
The cushioning member is pre-installed between the casing and the layered body to provide protective cushioning before expansion occurs. This beforehand cushioning prevents excessive load transmission to the layered body during the expansion process, thereby reducing breakage probability while maintaining structural integrity.
2Quantity of substance
If the adsorbent expands in the stacking direction, then dehumidification capacity is improved, but the load on the layered body increases and may cause breakage
Solution Approach 1:
The cushioning member acts as a mediator that allows the adsorbent to expand freely in the stacking direction to maintain dehumidification capacity, while simultaneously distributing and reducing the expansion load that would otherwise be transmitted to the layered body structure.
3Strength
If the casing material and thickness are adjusted to accommodate expansion, then structural integrity is improved, but device complexity and manufacturing cost increase
Solution Approach 1:
Instead of modifying the casing design to accommodate expansion, a cushioning member is introduced as a simpler intermediary solution. This approach maintains the original casing design while adding a relatively simple component that absorbs expansion forces, thereby avoiding increased device complexity and manufacturing cost.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The cushioning member reduces the load on the layered body during expansion, minimizing the risk of breakage and maintaining dehumidification performance by allowing air to pass through while maintaining contact between the layered body and the casing.
Implementation Method 1
the cushioning member being configured to expand and contract
Implementation Method 2
an adsorbent that adsorbs and desorbs moisture in air

AI summary
A dehumidifying element includes: a layered body in which a plurality of sheets supporting an adsorbent that dehumidifies air are stacked on one another, with gaps provided between adjacent ones of the plurality of sheets, the gaps allowing air to pass therethrough; a casing that holds the layered body; and a cushioning member provided between the casing and the layered body in a stacking direction in which the plurality of sheets are stacked on one another, the cushioning member being configured to expand and contract.
