Reusable Moisture Removal Pouch with Segmented Silica Compartments
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions for moisture removal from electronic devices are inefficient, cumbersome, and costly, often requiring new desiccant for each use and involving complex, expensive airtight containers that are not readily available when needed.
Innovation Solution
A reusable moisture removal pouch with permanently sealed desiccated silica compartments on both sides of the pouch, allowing bi-directional moisture flow and a non-airtight sealable design for easy use and reusability, specifically sized for standard smartphones.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If desiccant is used to remove moisture from electronic devices, then moisture removal effectiveness is improved, but desiccant must be replaced after each use increasing cost and reducing availability
Solution Approach 1:
The pouch is divided into separate compartments: a desiccant compartment containing reusable desiccant beads and a device compartment for the electronic device. This segmentation allows the desiccant to be separated from the device, enabling reuse of the desiccant while maintaining effective moisture removal from the device.
Solution Approach 2:
The system allows recovery and reuse of the desiccant material. After moisture removal, the desiccant can be regenerated by heating to drive off absorbed moisture, allowing it to be used again for subsequent moisture removal events, eliminating the need to discard and replace desiccant after each use.
2Reliability
If an airtight sealed container is used to prevent desiccant from absorbing environmental moisture, then desiccant effectiveness is improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The container is segmented into a desiccant compartment and a device compartment separated by a barrier that is air and moisture permeable to device side but impermeable to desiccant side. This allows the desiccant to be protected from environmental moisture while maintaining simplicity in the sealing mechanism.
Solution Approach 2:
An air and moisture permeable barrier acts as an intermediary between the desiccant compartment and device compartment. This barrier selectively allows moisture vapor to pass from the device side while preventing environmental moisture from reaching the desiccant, achieving protection without complex sealing.
3Ease of manufacture
If desiccant compartment is positioned adjacent to one side of device, then manufacturing simplicity is improved, but moisture removal efficiency decreases requiring longer drying time
Solution Approach 1:
The pouch is segmented with desiccant compartments positioned at both ends of the device compartment. This segmentation allows moisture to be drawn from both sides of the device simultaneously, doubling the effective moisture removal rate while maintaining manufacturing simplicity through modular compartment design.
4Ease of operation
If single-use disposable bags are used for moisture removal, then ease of operation is improved, but cost increases and availability decreases for subsequent emergencies
Solution Approach 1:
The pouch is designed for multiple uses through recovery and regeneration of the desiccant. After use, the desiccant can be regenerated by heating to remove absorbed moisture, allowing the same pouch to be reused for subsequent moisture removal events, eliminating the need for single-use disposable bags.
Solution Approach 2:
The pouch serves multiple functions: it can be used repeatedly for moisture removal from different devices, the desiccant can be regenerated and reused, and the same pouch structure handles both moisture absorption and device protection functions across multiple use cycles.

AI summary
A moisture removal pouch is disclosed with a main pouch body including a front panel portion defining at least one permanently sealed front compartment with desiccated silica permanently sealed therein, a rear panel portion opposite the front panel portion and defining at least one permanently sealed rear compartment with desiccated silica permanently sealed therein, the front and rear panel portions permanently sealed together at a bottom edge and side edges so as to define an electronic device receiving cavity and a main pouch body opening sized to receive an electronic device into the electronic device cavity. The pouch also includes an air-permeable inner liner facilitating a moisture removal operational configuration in which the main pouch body opening is closed in a non-airtight sealable manner and includes a pouch cover disposed to selectively cover the main pouch body opening in the non-airtight sealable manner.
