Battery Pack with Electrostatic Connector for Safe Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional battery packs in electronic devices are difficult to replace, often requiring device repair or replacement, and existing removal methods like adhesive tapes are inefficient and prone to damage or fire risks.
Innovation Solution
A battery pack design incorporating an electrostatic force load element or temperature cut-off element in the connector system that induces controlled short circuit to swell the battery, allowing easy removal without additional tapes, using connectors and terminals to facilitate detachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a pouch-shaped battery is embedded in an electronic device with ultrasonic welding or laser welding for waterproof and dustproof purposes, then the waterproof and dustproof performance is improved, but the ease of battery replacement deteriorates
Solution Approach 1:
The invention separates the battery pack into a battery cell and a separate case that can be easily detached. The case includes a connection portion with engagement protrusions that can snap into engagement recesses, allowing the battery pack to be divided into replaceable segments without compromising the sealing of the main device.
Solution Approach 2:
The invention introduces a separate battery pack case as an intermediary component between the battery cell and the electronic device. This case includes a connection portion with engagement protrusions that interface with engagement recesses in the device, providing a removable interface that maintains sealing while enabling easy replacement.
2Stability of the object's composition
If adhesive or string-shaped adhesive tape is added to one surface of the pouch-shaped battery for internal fixing, then the battery fixation is improved, but the ease of battery separation deteriorates and fire risk increases
Solution Approach 1:
The invention extracts the adhesive and string-shaped adhesive tape from the battery fixation system. Instead, it uses a mechanical engagement system where engagement protrusions on the connection portion fit into engagement recesses, eliminating the need for adhesive materials that are difficult to remove and pose fire risks.
Solution Approach 2:
The invention replaces the chemical bonding method (adhesive) with a mechanical engagement system. The connection portion includes engagement protrusions that mechanically interlock with engagement recesses, providing secure fixation during use while allowing easy separation without the fire risks associated with adhesive materials.
3Ease of operation
If a separate tape for removal is attached to the battery pack, then the ease of battery removal is improved, but the device complexity increases
Solution Approach 1:
The invention merges the removal function into the battery pack case itself. The connection portion includes engagement protrusions that integrate the attachment and release mechanisms within the existing battery pack structure, eliminating the need for separate removal tapes or additional components.
Solution Approach 2:
The connection portion serves multiple functions: it provides mechanical engagement for secure mounting, enables easy separation through the engagement protrusion-recess interface, and eliminates the need for separate removal aids. This multi-functional design simplifies the overall system while maintaining ease of removal.
