Integrated Circuit Substrate Battery with Sealed Electrodes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing portable electronic devices face challenges in reliable electricity supply due to the need for precise alignment of battery tabs and contacts, which increases manufacturing costs and limits flexibility, and the separate packaging of batteries and functional modules leads to material and manufacturing inefficiencies, as well as potential electrolyte leakage and moisture intake.
Innovation Solution
A system integrating a first and second conversion unit with a separator portion on a circuit substrate, where the separator includes through holes greater than 10 microns and insulators with holes less than 10 microns, formed from materials like PI, PET, and glass fiber, to prevent short circuits and allow ion flow, while a packaging unit surrounds the conversion units to prevent leakage and moisture intake.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If tabs protrude from package to perform interface functions, then electrical connection is enabled, but gaps at junctions cause electrolyte leakage and moisture intake
Solution Approach 1:
The patent merges the package and tabs into a single integrated structure where tabs are formed as extensions of the package body rather than separate components. This integration eliminates gaps at junctions, preventing electrolyte leakage and moisture intake while maintaining electrical connection functionality.
Solution Approach 2:
The package structure serves multiple functions simultaneously: it provides mechanical enclosure, electrical connection through integrated tabs, and sealing protection. The unified structure combines packaging and electrical interface functions into one component, eliminating the need for separate sealing at tab junctions.
2Reliability
If separate packages are used for battery and functional module, then component protection is achieved, but manufacturing and material costs increase
Solution Approach 1:
The patent combines the battery package and functional module package into a single integrated package structure. This unified packaging approach reduces manufacturing steps, eliminates the need for separate packaging processes, and lowers material costs while still providing adequate protection for both components.
3Adaptability or versatility
If conductive wires are implemented between contacts and tabs, then flexibility is provided, but alignment requirements increase and manufacturing costs rise
Solution Approach 1:
The patent merges the electrical connection function directly into the package structure through integrated tabs that extend from the package body. This eliminates the need for separate conductive wires and reduces alignment requirements, as the tabs are precisely positioned during package formation rather than requiring post-assembly alignment.
4Adaptability or versatility
If conductive wires are used to provide flexibility, then device flexibility is improved, but wire durability decreases due to bending damage
Solution Approach 1:
The patent extracts the conductive wire component entirely from the system by integrating electrical connections directly into the package structure. This eliminates the durability issues associated with bent wires while maintaining flexibility through the integrated tab design that can accommodate device movement without mechanical stress concentration.
