Battery Unit Escape Section for Slim Housing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional battery units for portable computers struggle to reduce the thickness of the housing while increasing battery capacity, as the extended portion and thin wall portion layout does not effectively utilize space to slim down the device.
Innovation Solution
The battery unit incorporates an escape section with a thin wall portion and recessed design that allows the pointing device and its holding part to be layered within the case, enabling the battery unit to be placed in a way that reduces the overall thickness of the portable computer housing.

Engineering Contradiction Analysis
1Quantity of substance
If the extended portion layout is used to increase battery capacity, then the battery capacity is improved, but the thickness of the housing cannot be decreased
Solution Approach 1:
The patent transitions from a two-dimensional planar layout (extended portion adjacent to thin wall portion) to a three-dimensional stacked layout (escape section positioned above/below the case). This dimensional change allows the battery unit to achieve increased capacity while reducing housing thickness by utilizing vertical space rather than horizontal extension.
Solution Approach 2:
The escape section is nested within the space above or below the case, similar to a nested doll structure. This allows the battery unit components to be arranged in a compact, space-efficient manner that maximizes battery capacity while minimizing the overall housing thickness.
2Volume of stationary object
If the extended portion is formed by cutting off the end portion, then the substrate can be housed to maximize cell space, but the device cannot be made slimmer
Solution Approach 1:
Instead of extending the case horizontally to accommodate the substrate and maximize cell space, the patent positions the escape section vertically above or below the case. This dimensional shift allows full utilization of cell space while reducing the horizontal footprint and overall housing thickness.
Solution Approach 2:
The battery unit is segmented into distinct functional sections: the case for cell accommodation, the escape section for substrate housing, and the thin wall portion for structural integration. This segmentation allows each component to be optimized independently for its specific function while contributing to the overall compact design.
