Bent Battery Structure for Higher Capacity in Compact Electronics
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge is to design an electronic device with a high-capacity battery that maintains a compact size, as increasing the battery size to accommodate higher capacity reduces user convenience and makes it difficult to downsize the device.
Innovation Solution
The solution involves a battery design with a first surface facing the display, a second surface opposite to the first surface, and a side surface between them, featuring a first attachment member on the first surface to fix the battery to a supporting member and a second attachment member with portions surrounding the side surface, including bending areas that extend towards the display, allowing for increased capacity without increasing the external dimensions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the battery size is increased to accommodate higher capacity, then the battery capacity is improved, but the device size increases and user convenience deteriorates
Solution Approach 1:
The battery is designed with a bending area that extends from the first surface toward the display, utilizing the third dimension (depth/thickness) to increase capacity. The battery main body has a first surface facing the display and a second surface opposite to it, with a bending area extending from the first surface. This dimensional approach allows the battery to occupy vertical space within the device housing rather than only horizontal space, thereby increasing capacity without increasing the device's external footprint.
Solution Approach 2:
The battery incorporates a bending area with a curved surface that extends from the first surface of the battery main body toward the display. This curved configuration allows the battery to fit into the available space more efficiently, utilizing the vertical dimension within the device housing. The curvature enables the battery to increase its volume and capacity while maintaining a compact device form factor, as the bent portion fits into the space between the battery main body and the display assembly.
2Quantity of substance
If the battery size is increased to accommodate higher capacity, then the battery capacity is improved, but the ease of operation deteriorates
Solution Approach 1:
The battery utilizes the vertical dimension within the device housing by extending a bending area from the first surface toward the display. This allows the battery capacity to be increased without increasing the device's external dimensions, thereby maintaining user portability and convenience. The battery fits within the existing device footprint while providing higher capacity through optimized internal space utilization in the vertical direction.
3Reliability
If the battery is fixed securely to the supporting member, then the reliability is improved, but the device complexity increases
Solution Approach 1:
The attachment structure is divided into two distinct attachment members: a first attachment member disposed on a first area of the first surface to fix the battery to the supporting member, and a second attachment member with a first portion on a second area of the first surface and a second portion surrounding at least a portion of the side surface. This segmentation allows each attachment member to perform a specific function - the first attachment member provides primary fixation while the second attachment member provides additional securing through the side surface. The divided approach simplifies the overall design compared to a single complex attachment mechanism, as each segment can be independently optimized and manufactured.
Solution Approach 2:
The second attachment member serves multiple functions: its first portion is disposed on the first surface to provide attachment, while its second portion surrounds at least a portion of the side surface to provide additional securing. This multi-functional design allows a single attachment component to perform both surface mounting and side surface securing, reducing the total number of separate parts needed and simplifying the overall attachment structure while maintaining reliable battery fixation.
