Battery Compartment Heaped Bale Structure for Thickness Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery accommodating devices for handheld electronic devices, such as small-sized video cameras, face challenges in reducing thickness due to the high stacking height of dry batteries when arranged in a heaped bale structure, which increases the device's thickness and allows for rattling.
Innovation Solution
The electronic device incorporates a battery accommodating portion with support recess portions that allow dry batteries to be stacked in a heaped bale structure with intervals between adjacent batteries, reducing the overlapping width and height, and using a rechargeable battery to maintain compactness and suppress rattling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If dry batteries are arranged in contact with each other on the upper tier in a heaped bale structure, then the battery accommodating device can accommodate multiple dry batteries, but the height in the stacking direction becomes high, increasing the thickness of the device
Solution Approach 1:
The patent changes the arrangement pattern of dry batteries from a conventional stacked configuration to a heaped bale structure where batteries are arranged in an interlocking pattern. This dimensional rearrangement allows batteries to nestle into each other's spaces, reducing the overall height in the stacking direction while maintaining the quantity of accommodated batteries, thereby reducing device thickness
2Length of stationary object
If dry batteries are arranged in contact with each other on each tier, then the height in the stacking direction is reduced, but the dry batteries can rattle and move, reducing stability
Solution Approach 1:
The patent utilizes the cylindrical shape of dry batteries and arranges them in a heaped bale structure where the curved surfaces of adjacent batteries interlock. This curvature-based arrangement creates natural mechanical interlocking that prevents rattling and movement, enhancing stability while maintaining a compact height in the stacking direction

AI summary
The disclosure discloses an electronic device comprising a battery accommodating portion. The battery accommodating portion is configured to alternatively accommodate a plural of cylindrical dry batteries or a cuboid rechargeable battery. The battery accommodating portion, when a plurality of the dry batteries are arranged by being stacked in two tiers or more into a heaped bale structure when the dry batteries are accommodated, comprises a plurality of support recess portions configured to support a plurality of the dry batteries in a bottom tier, respectively. An interval between axes of the support recess portions adjacent to each other is larger than an outer diameter of each of the dry batteries and is smaller than twice of the outer diameter of each of the dry batteries.
