Solution Overview
Problem
Rechargeable batteries in portable electronic devices face challenges in integrating additional functions like antenna assemblies without occupying additional space, especially as devices become smaller and more spatially restricted.
Innovation Solution
Incorporating a line antenna assembly within the rechargeable battery's design, which includes a substrate, metal plate, and adhesive layer, integrated with the battery's outer case and can, allowing for RF signal reception without requiring extra space, and utilizing a barrier wall for secure attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If an antenna assembly is integrated into the rechargeable battery, then RF signal reception capability is added, but the battery structure becomes more complex
Solution Approach 1:
The antenna assembly is merged with the battery structure by integrating it into the outer case. The outer case serves dual purposes: protecting the battery and housing the antenna assembly, thereby adding RF reception capability without requiring a completely separate antenna structure.
Solution Approach 2:
The outer case is designed to perform multiple functions: it protects the battery cell and circuit, provides structural support, and houses the antenna assembly for RF signal reception. This multi-functionality reduces the need for additional separate components.
2Adaptability or versatility
If the antenna assembly is added to the battery, then additional functions are provided, but the available space in portable devices is reduced
Solution Approach 1:
The antenna assembly is combined with the battery's outer case structure, allowing the antenna to occupy space that would otherwise be structural or protective space in the battery housing. This integration ensures that the antenna functionality is achieved without requiring additional volume beyond what is already allocated for the battery housing.
3Volume of moving object
If the antenna assembly is integrated into the battery, then space efficiency is improved, but the antenna design freedom is restricted
Solution Approach 1:
The outer case is designed with specific local features to accommodate the antenna assembly, such as dedicated cavities or regions within the case structure. This allows the antenna to be positioned and configured optimally for RF performance while maintaining overall space efficiency. The local modification of the case structure provides design freedom for the antenna without compromising the compact overall design.
