Battery Isolation Tab for Remote Control Charge Preservation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Handheld electronic devices often experience premature battery drain due to ongoing contact between batteries and electrical connection terminals during storage, leading to reduced battery life before the device is deployed.
Innovation Solution
The implementation of a battery isolation tab, typically made of flexible plastic, which is positioned between the battery and the electrical connection terminals, preventing premature contact and allowing for easy removal when the device is ready for use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the battery is placed in direct contact with electrical connection terminals during storage, then the device is ready for immediate use upon battery installation, but the battery charge is prematurely drained
Solution Approach 1:
A non-conductive tab is introduced as an intermediary element between the battery terminal and the electrical connection terminal. This tab physically separates the two conductive surfaces during storage, preventing electrical contact and charge drain, while allowing easy removal when battery installation is needed.
Solution Approach 2:
The harmful element (electrical contact pathway) is extracted or removed from the system during storage by introducing the isolation tab. The tab is taken out or removed when the device needs to be activated, allowing the battery to make contact with the terminals.
2Reliability
If a battery isolation tab is introduced to prevent premature discharge, then battery charge is preserved during storage, but the device structure becomes more complex
Solution Approach 1:
The isolation tab is made from a thin, flexible non-conductive material that can be easily integrated into the device structure. This thin-film approach minimizes the added structural complexity while effectively preventing electrical contact between the battery and terminals during storage.
3Ease of operation
If the battery isolation tab is made of flexible plastic, then easy removal is enabled, but electrical insulation effectiveness may be reduced
Solution Approach 1:
The material properties of the tab are optimized by selecting a non-conductive plastic material that provides sufficient electrical insulation while maintaining flexibility for easy removal. The thickness and material composition are adjusted to balance insulation effectiveness with ease of handling and removal.

AI summary
Handheld remote control assemblies with battery isolation tabs are disclosed. An assembly includes a body and a battery pocket formed in the body and defined by a sidewall and a lower surface. An electrical connection terminal is disposed on the lower surface, and a battery is disposed within the battery pocket. The body includes a channel formed therein and extending between the battery pocket and an edge of the body. A battery isolation tab includes a head portion disposed between the battery and the electrical connection terminal, a handle portion disposed external to the body, and a neck portion extending between the head portion and the handle portion, the neck portion at least partially received within the channel formed in the body.
