Single-Piece Battery Packaging with Integrated Partition and Lid
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery packaging solutions require multiple parts and assembly steps, leading to increased complexity and potential for damage during handling and transportation.
Innovation Solution
A single-piece battery packaging container formed from a single paper template, featuring integrated walls and flaps that support and secure the battery, reducing the number of parts and assembly steps while providing stable storage and protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple parts (exterior box, cover plate, lid plate) are used to package batteries, then the packaging structure provides adequate protection and support, but the number of assembling steps and number of parts increases
Solution Approach 1:
The patent combines multiple separate packaging components (exterior box, cover plate, lid plate) into a single integrated packaging structure. The battery pack case is formed as one piece that incorporates both the container walls and the cover function, eliminating the need for separate assembly of multiple parts while maintaining protective functionality.
Solution Approach 2:
The single-piece battery pack case serves multiple functions simultaneously: it acts as the container walls, the cover, and the structural support element. This multi-functional design replaces the need for separate exterior box and lid plate components, reducing part count while maintaining all necessary protective and structural functions.
2Reliability
If multiple parts (exterior box, cover plate) are used to package batteries, then adequate protection is provided, but the number of assembling steps increases
Solution Approach 1:
The patent merges the cover function and container function into a single integrated piece. The battery pack case is formed as one component that eliminates the need for separate assembly steps of attaching cover plates and lid plates, thereby reducing assembly time and steps while maintaining protective functionality.
3Device complexity
If a single-piece structure is used, then the number of parts and assembling steps is reduced, but the structural support and protection capability may be compromised
Solution Approach 1:
The single-piece battery pack case incorporates integrated support structures including side support portions and end support portions that are formed as integral parts of the case walls. These support structures are strategically positioned to provide adequate structural support and battery stabilization without requiring separate components, thus maintaining reliability while using a single-piece construction.

AI summary
A battery packaging container (10) of the present invention includes: a plate-shaped bottom wall (20); a first lateral wall (31) formed integrally with the bottom wall and extending upward from a first edge (21) that is part of a contour of the bottom wall; a second lateral wall (32) formed integrally with the bottom wall and extending upward from a second edge (22) that is a portion opposing to the first edge in the contour of the bottom wall; a partition wall (40) formed integrally with the first lateral wall and extending diagonally from an upper end (31b) of the first lateral wall toward the second edge of the bottom wall; and a lid (60) formed integrally with the second lateral wall and extending from an upper end (32b) of the second lateral wall to cover the partition wall from above. The partition wall includes a storage hole (41) to store a battery, the storage hole (41) being defined by an end portion (42) of the partition wall, a root portion (43) located on an opposite side of the end portion, and a pair of lateral portions (44, 45) connecting the end portion and the root portion.
