Dehumidification bag and preparation method thereof
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dehumidification bags suffer from moisture absorption during storage and transportation, leading to dehumidifier deterioration or failure due to their double-layer structure, which results in poor dehumidification effectiveness and shortens the dehumidifier's lifespan.
Innovation Solution
A dehumidification bag design featuring a bag body composed of air-permeability films and a moisture-proof layer, where the air-permeability film is covered with a tearable moisture-proof layer to prevent moisture absorption, allowing for self-standing and easy replacement of the dehumidifier, and is placed at the bottom of a wardrobe for enhanced dehumidification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a double-layer structure (outer bag and inner bag body) is used for dehumidification packaging, then the dehumidifier is protected during storage, but the non-woven fabric with air-permeability allows moisture to pass through and absorb by the dehumidifier, causing deterioration or failure
Solution Approach 1:
The patent divides the protective structure into three distinct layers: an outer bag for mechanical protection, an inner bag made of moisture-proof material to block moisture, and a desiccant layer to absorb any remaining moisture. This segmentation allows each layer to perform its specific function, preventing the dehumidifier from absorbing moisture during storage and transportation while maintaining its effectiveness.
2Ease of operation
If the inner bag body uses non-woven fabric with air-permeability, then breathability is achieved, but the dehumidifier absorbs moisture from the air in the outer bag through the permeable fabric
Solution Approach 1:
The patent introduces a moisture-proof inner bag as an intermediary layer between the breathable outer bag and the dehumidifier. This inner bag made of moisture-proof material blocks moisture transmission while allowing the outer bag to maintain breathability. The desiccant layer acts as a secondary intermediary to capture any moisture that might penetrate, ensuring the dehumidifier remains protected while the packaging maintains its breathability characteristics.

Function Achieved in This Case
The solution effectively prevents moisture absorption, maintains dehumidifier effectiveness during storage and transportation, allows for easy replacement, and improves dehumidification efficiency by placing the bag at the bottom of a wardrobe where humidity accumulates, extending the dehumidifier's lifespan and reducing costs.
Implementation Method 1
a moisture-proof layer, covering an outside of the air-permeability film
Implementation Method 2
the side sheet comprises an air-permeability film and/or a composite film, wherein, part or all of at least one side sheet is the air-permeability film
Implementation Method 3
a storage compartment formed by heat sealing the first side sheet and the second side sheet

AI summary
The present invention relates to a dehumidification bag and a preparation method thereof. The dehumidification bag comprises a bag body including a first side sheet and a second side sheet, the side sheet comprises an air-permeability and/or a composite film, wherein at least all or part of at least one side sheet is an air-permeability film; a moisture-proof layer covers the outside of the air-permeability. The dehumidification bag provided by the present invention provides an air-permeability on the bag body, and adopts heat sealing between the outer surface of the air-permeability layer and the moisture-proof layer, so that the air-permeability and the moisture-proof layer are in close contact without moisture absorption, which effectively prevents damage during transportation and storage. In the process, the air-permeability is in contact with the air in the outer bag and the effect of the dehumidifier becomes poor or invalid; by setting the moisture-proof layer to be tearable, when the buyer uses the dehumidification bag, the moisture-proof layer can be torn off, which is convenient and fast.
