Battery Outer Case Display Integration for Lower Device Volume
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The integration of a display panel with a lithium secondary battery increases the volume of portable electronic devices due to the additional space required for both the battery and the display panel, necessitating a design that minimizes overall volume.
Innovation Solution
A lithium secondary battery with an integrated display panel, where at least one surface of the outer case serves as the display panel, incorporating a circuit structure electrically connected to the electrode assembly and a sealing case to drive the display panel without an external circuit, thereby reducing the need for a separate display panel and enhancing space efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a separate display panel is attached to the lithium secondary battery, then the display functionality is achieved, but the volume of the portable electronic device increases
Solution Approach 1:
The patent merges the display panel with the outer case of the lithium secondary battery by making the outer case itself serve as the display panel. This integration eliminates the need for a separate display component, thereby achieving display functionality while minimizing device volume.
Solution Approach 2:
The outer case of the battery is designed to serve multiple functions: it provides structural protection for the battery components and simultaneously functions as a display panel. This multi-functionality reduces the overall number of components needed and decreases device volume.
2Adaptability or versatility
If a separate display panel and battery are included, then both functions are achieved, but space efficiency is reduced
Solution Approach 1:
The display panel and battery are merged into a single integrated structure where the outer case serves dual purposes. This merging eliminates wasted space between separate components and maximizes space efficiency while maintaining both display and power storage functions.
3Adaptability or versatility
If the outer case is designed to accommodate both battery and display, then functionality is maintained, but the volume increases
Solution Approach 1:
The outer case is designed as a multi-functional component that simultaneously serves as the battery housing and the display panel. This eliminates the need for additional volume to accommodate a separate display unit, thereby reducing overall battery pack volume while maintaining integrated functionality.

AI summary
A lithium secondary battery with an integrated display panel may include an electrode assembly including a cathode and an anode disposed to face the cathode, and an outer case which accommodates the electrode assembly and has at least one surface provided as a display panel. By providing at least one surface of the outer case as the display panel, a secondary battery having the reduced volume may be provided when designing the secondary battery with the same capacity.
