Removable Coin Battery Board for Closed-Housing Exchange
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery exchange systems require opening the housing of an electronic device to exchange batteries, which can lead to mechanical damage.
Innovation Solution
A battery exchange system that includes a dummy battery unit and a battery board unit that can be attached to a circuit board of an electronic device, with a battery board battery holder that is a battery holder for a button-type battery, and a battery board that is disposed in the electronic device so as to be insertable and removable from the outside of the housing of the electronic device.

Engineering Contradiction Analysis
1Ease of operation
If the housing is opened to exchange the battery, then the battery can be replaced, but the housing may suffer mechanical damage
Solution Approach 1:
The battery holder is divided into two separate components: a circuit board battery holder that remains permanently attached to the circuit board inside the housing, and a removable battery board that can be detached and reattached through the housing opening. This segmentation allows battery replacement without permanently opening the housing, thus preventing mechanical damage while maintaining ease of operation.
2Ease of operation
If a removable battery board is added, then battery exchange is enabled without opening the housing, but the device complexity increases
Solution Approach 1:
The battery holder structure is merged with the circuit board by permanently attaching the circuit board battery holder to the circuit board. This integration eliminates the need for a separate, complex removable battery compartment structure, reducing overall device complexity while still enabling easy battery replacement through the removable battery board.
