Three-Layer Leak-Proof Packaging for Wet Batteries
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current packaging for damaged or leaking batteries with corrosive liquids is inadequate, as it often requires additional supplies for inspection, is not suitable for irregular shapes, and does not ensure leak-proof transport, potentially leading to safety issues and regulatory non-compliance.
Innovation Solution
A three-layer packaging system comprising an inner absorbent container, a fluid-impermeable intermediate plastic bag with a secure lock, and a sturdy outer container made of corrugated cardboard, designed for easy assembly, re-closure, and protection against punctures, with absorbent pads and buffers for added safety and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional packaging is used for damaged or leaking batteries, then the packaging may be fully sealed with adhesive or adhesive tape, but it requires additional supplies for reassembly during inspection and is not suitable for irregular shapes
Solution Approach 1:
The packaging is divided into multiple separable components: an inner container with removable lid, an intermediate container, and an outer container. This segmentation allows the inner container to be opened for inspection without requiring tools or additional supplies, while maintaining leak-proof capability through the design of the components.
Solution Approach 2:
The packaging uses a nested structure where the inner container is placed within the intermediate container, which is then placed within the outer container. This nested design provides multiple layers of protection while allowing easy access to the inner container for inspection, resolving the contradiction between leak-proof sealing and ease of inspection.
2Reliability
If traditional packaging is used for damaged or leaking batteries, then the packaging may be fully sealed, but it takes much extra space and is not suitable for irregular shapes
Solution Approach 1:
The segmented design with removable lids and separable containers allows the packaging to be configured to fit irregularly shaped batteries more efficiently, reducing wasted space while maintaining the leak-proof barrier through the multi-layer structure.
Solution Approach 2:
The packaging incorporates flexible elements such as the removable inner container lid and the ability to open/close the intermediate container, allowing the packaging to adapt to different battery shapes and sizes, improving space efficiency while maintaining protection.
3Reliability
If traditional packaging is used for damaged or leaking batteries, then the packaging may be fully sealed with adhesive, but it requires breakage to open for inspection
Solution Approach 1:
The packaging uses mechanical connections (removable lids, snap-fit components) instead of adhesive bonding, allowing the container to be opened for inspection without breaking or damaging any components, while still providing effective leak-proof sealing when closed.
Solution Approach 2:
The inner container lid is designed as a removable component that can be easily taken off and replaced if needed, eliminating the need for adhesive and allowing inspection without damaging the packaging structure.

AI summary
A leak-proof package for at least one defective battery containing corrosive liquid. The inventive package has at least three layers and includes an inner container configured to accept the battery therewithin, a fluid-impermeable intermediate container sealing the inner container therewithin, and an outer container enclosing the intermediate container such that the liquid-containing defective battery is protectively packaged for leak-free transportation. Another aspect of the present invention is a method for packaging at least one battery containing corrosive liquid by loading the battery into the inner container which is sealed within the intermediate container inside the locked outer container such that the liquid-containing defective battery is protectively packaged for leak-free transportation.
