Battery Packaging Body Infant-Proof Cuttable Region Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery packaging configurations are inadequate in preventing infants from accidentally removing batteries, while allowing adults to easily access them, as they either have weak adhesion between components or are easily opened by infants due to shallow cutting parts.
Innovation Solution
A battery packaging design featuring a plate-shaped mount and a blister cover with an accommodating projection, a non-fixed part, and rib parts that are fixed at the peripheral edges, allowing for easy adult access by cutting along a specific region that expands the opening when compressed, while maintaining infant-proof adhesion and rigidity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the blister cover and mount are fixed weakly to allow easy peeling, then a person can easily take out the battery, but an infant can also easily open the packaging and remove the battery
Solution Approach 1:
The packaging is divided into two distinct access methods: a cuttable region for adults that allows battery removal through cutting, and a peeling region that remains sealed to infants. The blister cover and mount are segmented with different fixation characteristics - strong fixation in the peeling region to prevent infant access, and a controlled cuttable region for adult access.
Solution Approach 2:
Different regions of the packaging have different fixation qualities. The peeling region has strong adhesion between the blister cover and mount to prevent infant opening, while the cuttable region has controlled fixation that allows adult access through cutting. This local differentiation of fixation strength resolves the contradiction between easy adult access and infant safety.
2Ease of operation
If a cutting scheduled part is provided in the blister cover, then an adult can cut along the line to open the packaging, but the three-dimensional portion becomes large and may break or peel when bent or twisted
Solution Approach 1:
The packaging structure is segmented into a cuttable region with controlled fixation and a peeling region with strong fixation. This segmentation allows the cuttable region to be opened cleanly without requiring large three-dimensional portions that would compromise structural integrity. The rib part provides localized reinforcement without creating excessive three-dimensionality.
Solution Approach 2:
The fixation parameter is changed locally - reduced fixation strength in the cuttable region to allow clean cutting, while maintaining strong fixation in the peeling region to preserve structural integrity. This parameter change enables easy opening without compromising the strength of the remaining structure.
3Object-affected harmful factors
If the mount and blister cover are fixed strongly to prevent infant opening, then infant safety is improved, but a person cannot easily take out the battery
Solution Approach 1:
The packaging is segmented into regions with different fixation characteristics. The peeling region maintains strong fixation to prevent infant opening, while the cuttable region has controlled fixation that allows adult access through cutting. This segmentation resolves the contradiction by providing different fixation strengths in different regions.
Solution Approach 2:
The cuttable region acts as an intermediary mechanism between the strong fixation required for infant safety and the easy access needed for adult use. Adults can cut through this intermediary region to access the battery, while the strong fixation in other regions continues to protect against infant opening.

AI summary
There is obtained a configuration of a battery packaging body which allows, while infants can hardly take out a battery, a person other than infants can take out the battery. A battery packaging body 1 includes a mount 10, and a blister cover 20 which can accommodate a battery 2 between the same and the mount 10. The mount 10 and the blister cover 20 are fixed to each other at least at their peripheral edge parts. The blister cover 20 has a non-fixed part 32 which is, at a position continuous to an accommodating projection 24, not fixed to the mount 10, and a first rib part 26a provided along the accommodating projection 24. The non-fixed part 32 is positioned on the opposite side to the first rib part 26a across the accommodating projection 24 and constitutes a part of a cuttable region P. The first rib part 26a extends in a direction crossing a direction in which the non-fixed part 32, the accommodating projection 24 and the first rib part 26a line up.
