Battery Packaging Interleaf Structure to Protect Recognition Codes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The recognition codes on cylindrical secondary batteries frequently get damaged due to friction during transportation, leading to difficulties in tracking and managing the batteries during manufacturing, distribution, and recycling processes.
Innovation Solution
A secondary battery packaging box and interleaf with a partition wall that includes a contact prevention portion, such as a perforated or recessed portion, designed to avoid contact with the recognition codes, ensuring they remain intact during transport.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If interleaves are provided inside the packaging box to separate and accommodate individual secondary batteries, then the batteries can be safely accommodated and moved, but the recognition code printed on the outer surface of the battery frequently contacts the interleaf during transport, causing damage to the recognition code
Solution Approach 1:
The patent introduces a protective film as an intermediary layer between the recognition code on the battery surface and the interleaf. This protective film prevents direct contact and friction between the recognition code and the interleaf, thereby protecting the recognition code from damage while maintaining the battery separation function of the interleaf.
Solution Approach 2:
The patent adds a new dimensional layer (the protective film) on top of the existing battery surface. This creates a protective barrier in a new dimension that prevents the recognition code from contacting the interleaf, effectively separating the protective function from the structural interleaf function.
2Loss of information
If the recognition code is printed on the outer surface of the cylindrical secondary battery for identification and tracking, then the battery can be identified and tracked during manufacturing, distribution, use, and recycling processes, but the recognition code is vulnerable to damage from contact and friction with the interleaf during transport
Solution Approach 1:
The protective film is applied to the battery surface before the battery is placed in the packaging box with the interleaf. This preliminary protective action ensures that the recognition code is already protected before any contact with the interleaf can occur during transport and handling.
Solution Approach 2:
The protective film serves as a mediator that allows the recognition code to maintain its identification function while being physically isolated from the harmful contact with the interleaf. The film transmits no information barrier, allowing the recognition code to function while providing mechanical protection.
3Ease of operation
If multiple cylindrical secondary batteries are accommodated in a packaging box with interleaves for separation, then the batteries can be individually accommodated and transferred, but friction between the interleaf and battery outer surface causes detachment or damage of the recognition code
Solution Approach 1:
The protective film acts as an intermediary layer that eliminates direct friction between the interleaf and the battery surface. This allows the interleaf to continue providing separation and handling functionality while the protective film absorbs the friction, preventing damage to the battery surface and recognition code.
