Battery Connector Layout for Thin Electronic Device Housing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices face challenges in achieving a slim design due to the need for a thick expansion space to accommodate battery expansion, which increases the overall thickness and hinders a light and thin design.
Innovation Solution
The electronic device design includes a battery compartment with a battery body wrapped by a wrapping film, where the electrical connector is positioned to avoid overlapping with the expanded region on the battery surface, allowing for a reduced thickness of the expansion space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the thickness of the electronic device is increased to reserve expansion space for the battery, then the battery expansion damage is avoided, but the electronic device thickness increases and light and thin design is hindered
Solution Approach 1:
The patent relocates the electrical connector from the thickness direction (Z-axis) to the plane direction (X-Y plane) of the battery. By placing the connector on the first surface of the battery body and ensuring it does not overlap with the expanded region, the design utilizes spatial reconfiguration to achieve both battery expansion accommodation and reduced device thickness.
Solution Approach 2:
The patent defines a specific expanded region on the battery body's first surface with precise dimensional parameters (distance d from the peripheral edge, where d≥0mm). The electrical connector is strategically positioned to avoid overlapping with this expanded region, creating localized functional zones that optimize both battery expansion capability and overall device thinness.
2Ease of operation
If the electrical connector is positioned on the battery surface, then the connection functionality is achieved, but the connector may overlap with the expanded region increasing the required expansion space thickness
Solution Approach 1:
The patent transitions the electrical connector's placement from the thickness direction to the battery's surface plane. By positioning the connector on the first surface and ensuring non-overlapping arrangement with the expanded region, the design achieves electrical connection functionality while minimizing the thickness requirement of the expansion space.
Solution Approach 2:
The patent pre-defines the expanded region's boundaries and characteristics on the battery body before final assembly. The electrical connector is then positioned to avoid this predetermined expanded region, ensuring that the connector placement does not interfere with battery expansion while maintaining electrical functionality.
