Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current dry room systems for manufacturing environments, such as those used for all-solid-state batteries, require large amounts of dry air to maintain a low dew point, leading to increased costs and time to establish and restore a dry environment, which is inefficient and costly.
Innovation Solution
A dry space creation system utilizing a hollow treatment tank with an inflatable balloon member and a dry air supply unit, where the inflatable balloon member is inflated with either inflation air or dry air to create a controlled dry environment within a smaller space, reducing the need for extensive dry air supply and shortening the time to achieve the desired dew point.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a wide dry room is used to house the entire manufacturing facility, then the dry environment can cover the predetermined area, but a large amount of dry air is necessary to maintain the dew point, increasing cost for air conditioning facility and supply of dry air
Solution Approach 1:
The patent applies local quality by creating a localized dry space (dry booth) rather than maintaining a wide dry room. The dry environment is concentrated in the specific area where the sulfide-based solid electrolyte is handled, using a dehumidification apparatus positioned within the dry booth to maintain low dew point only where needed, rather than throughout the entire manufacturing facility.
Solution Approach 2:
The patent segments the manufacturing facility into a localized dry space (dry booth) separated from the rest of the facility. This segmentation allows the dry environment to be maintained only in the necessary area, reducing the overall volume requiring dehumidification and thereby reducing the quantity of dry air needed while still providing adequate coverage for the specific manufacturing process.
2Area of stationary object
If a wide dry room is used to house the entire manufacturing facility, then the dry environment can cover the predetermined area, but it takes time to bring the inside of the dry room into the dry environment
Solution Approach 1:
By concentrating the dry environment in a localized dry booth rather than a wide dry room, the volume of air that needs to be dehumidified is significantly reduced. This allows the dehumidification apparatus to quickly bring the enclosed space to the target dew point, reducing the time loss while maintaining adequate coverage for the specific manufacturing area.
Solution Approach 2:
The patent employs a dehumidification apparatus with high dehumidifying capacity that can dynamically adjust to quickly establish the dry environment when needed. The system is designed to rapidly remove moisture from the localized dry space, minimizing the time required to reach and maintain the target dew point, especially important for quick restoration after maintenance or when workers enter the space.
3Area of stationary object
If a wide dry room is used to house the entire manufacturing facility, then the dry environment can cover the predetermined area, but workers perform operations in the wide dry room requiring further enhancement of dehumidifying capacity
Solution Approach 1:
The patent creates a localized dry space that provides sufficient coverage for worker operations on sulfide-based solid electrolyte without requiring a wide dry room. The dehumidification apparatus is positioned within this compact dry booth, providing concentrated dehumidification capacity exactly where workers need it, thereby maintaining the dry environment with minimal dry air consumption while still accommodating necessary operational space.
