Paper Battery Package Corner Layout to Prevent Drop Detachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional battery packages made from a single sheet of paperboard are prone to damage when dropped due to their design, which can lead to adhesive failure and batteries being dislodged, and they also face production issues with loose folds causing interference during manufacturing.
Innovation Solution
A battery package design where the margins around the battery compartment are shaped to not overlap with the mount at the lower corner, with set-back portions acting as shock absorbers and improved folding techniques to prevent interference during production.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If the margins overlap with the mount at the lower corner to form a compact shape, then the battery package has a neat appearance and complete coverage, but the adhesive strength decreases when dropped causing batteries to pop out
Solution Approach 1:
The patent extracts the problematic overlapping portion at the lower corner by introducing a set-back portion that removes the margin overlap with the mount at this specific location. This extraction eliminates the source of adhesive failure while preserving the compact shape and complete coverage in other areas.
Solution Approach 2:
The patent applies local quality by making the margin shape different at the lower corner compared to other areas. The set-back portion creates a localized modification where the margin does not overlap the mount, while other portions maintain their traditional overlapping configuration for neat appearance and coverage.
2Ease of manufacture
If the margins are folded outside the three surfaces to simplify manufacturing, then the production process is easier, but the fold may become loose and cause interference during subsequent folding steps
Solution Approach 1:
The patent applies preliminary anti-action by pre-configuring the margin shape with the set-back portion before folding. This preliminary design prevents the margin from becoming loose during the folding process, as the set-back geometry inherently maintains fold tightness without requiring additional corrective measures during manufacturing.

AI summary
This battery package has a paper board part formed of paper and a battery storage part formed by folding a paper, wherein: the battery storage part has a bottom portion coupled to the paper board part; three surfaces around the battery storage part are adhered to the paper board part by a sticking margin portion; and the sticking margin portion has a shape which does not overlap the paper board part in a lower corner portion of the battery package.
