Battery Housing Merged with Device Structure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional rechargeable batteries with metal housings restrict the design of miniaturized electronic devices due to their size and weight, limiting the freedom of design and compactness of these devices.
Innovation Solution
A battery housing that forms a hollow body, allowing the outer casing to serve as part of the device's housing, enclosing the battery's active components and accommodating device components, thereby reducing the need for separate housings and minimizing weight and volume.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional rechargeable batteries with metal housings are used, then the battery provides sufficient power and reliability, but the device weight and volume increase, restricting design freedom
Solution Approach 1:
The battery housing is merged with the device housing to form a unified structure. The battery's outer casing simultaneously serves as the device's housing, eliminating the need for separate housing components and reducing overall device weight while maintaining structural integrity and power supply reliability
Solution Approach 2:
The battery housing performs multiple functions: it encloses the battery's active components (electrodes, electrolyte), provides structural support, serves as the device's external housing, and creates an accommodation space for device components. This multi-functionality reduces the number of separate components needed
2Reliability
If conventional rechargeable batteries with metal housings are used, then the battery provides sufficient power, but the device volume increases, restricting compact design
Solution Approach 1:
The battery housing and device housing are combined into a single integrated structure. The battery's outer casing forms the device's housing, eliminating redundant housing materials and reducing overall device volume while maintaining sufficient space for battery components and device electronics
Solution Approach 2:
The device components are nested within the accommodation space formed by the battery housing. The battery housing encloses both the battery's active portion and the device components, creating a compact nested arrangement that minimizes device volume
3Reliability
If separate battery housing and device housing are used, then the battery components are protected, but weight and volume increase
Solution Approach 1:
The battery housing and device housing are merged into a single integrated structure. This unified housing simultaneously protects the battery's active components (electrodes, electrolyte) and provides the device's external structure, eliminating the weight of separate housing components while maintaining adequate protection

AI summary
A battery comprises a battery housing and an electrode which is accommodated in the battery housing. Outer faces of the battery housing substantially form the shape of a hollow body which has an accommodation space for accommodating at least a substantial portion of a device which is to be supplied with power by the battery. An outer casing surface of the battery housing can therefore form a portion of a housing of the device. Since the battery housing protects both the active portion of the battery enclosed therein and the components of the device accommodated in the accommodation space of the battery, and a separate device housing and battery housing can therefore be largely avoided, there is a resultant saving in weight and volume. The freedom of design for devices which are provided with batteries is also increased.
