Battery Frame Packaging With Anti-Noise Member for Thin Battery Packs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Battery packs in electronic devices generate noise due to repeated detachment of adhesive surfaces from the frame, causing inconvenience, especially when the device is bent or deformed.
Innovation Solution
A battery pack design incorporating an anti-noise member attached to the adhesive surface of the packaging member, which includes ridged portions to contact the battery management unit and thermally conductive materials to minimize gaps, along with dented grooves and barriers to reduce noise and weight.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the battery pack is made thin to accommodate miniaturized electronic devices, then the volume and thickness are reduced, but the adhesive surface repeatedly bonds to or separates from the frame causing noise
Solution Approach 1:
An anti-noise member is introduced as an intermediary element between the adhesive surface and the frame. This member absorbs the impact and prevents direct contact between the adhesive and frame during bending, thereby eliminating the noise caused by repeated bonding and separation while maintaining the thin profile of the battery pack
2Strength
If the adhesive surface area is increased to improve fixation, then the bonding strength increases, but the flexibility of the thin battery pack decreases and noise increases
Solution Approach 1:
The anti-noise member is strategically positioned at specific locations where noise is generated during bending, rather than covering the entire adhesive surface. This localized approach maintains the necessary flexibility of the thin battery pack while providing noise reduction at critical points
