Movable Battery Receiving Assembly for Portable Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable electronic devices face limitations in battery selection due to the shape and size of the battery compartment and electric terminals, making it impractical to accommodate multiple battery types without cumbersome adapters that can be misplaced.
Innovation Solution
A movable battery receiving assembly with interchangeable contacts for different battery types, allowing the device to be powered by either cylindrical or prismatic shape batteries, with a unitary adapter plate that can be rotated to expose appropriate contacts and spacers for secure fitting and connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate battery adapters are provided for different battery types, then the device can accommodate multiple battery types, but the device complexity increases and the adapters can be misplaced
Solution Approach 1:
The patent combines multiple battery adapter configurations into a single integrated adapter plate that can be rotated to expose different contact arrangements. This merging eliminates the need for multiple separate adapters while maintaining compatibility with different battery types, thus reducing device complexity while preserving adaptability.
Solution Approach 2:
The adapter plate incorporates a rotational mechanism that allows dynamic reconfiguration of the contact arrangement. By rotating the adapter plate, the device can switch between different battery type configurations (e.g., single battery, dual battery, different orientations), providing adaptability without requiring multiple static adapters.
2Adaptability or versatility
If the battery compartment is designed to accommodate multiple battery types, then battery versatility improves, but the battery compartment size and shape must increase to fit all configurations
Solution Approach 1:
The rotational adapter plate enables the battery compartment to dynamically adapt its internal configuration without physically expanding. By rotating the adapter plate to different angular positions, the same compact compartment space can accommodate various battery types and arrangements, eliminating the need for increased compartment volume.
Solution Approach 2:
The single adapter plate serves multiple functions by supporting different battery configurations through rotation. This universal design allows one compact compartment to handle various battery types (e.g., cylindrical, prismatic, different numbers of batteries) without requiring separate compartments for each battery type, thus maintaining compact size while achieving versatility.
3Reliability
If fixed electric terminals are used for a specific battery type, then the connection reliability improves, but the device cannot accommodate different battery types without adapters
Solution Approach 1:
The adapter plate provides reliable electrical connections through fixed contacts for each configuration, while the rotational mechanism enables dynamic switching between different battery types. Each contact arrangement maintains stable electrical connectivity when engaged, yet the system as a whole adapts to different battery types through rotation, combining reliability with flexibility.

AI summary
Described is a portable electronic device which may include a body accommodating electrical components of the device. The body defines a battery chamber and a battery receiving element movably mounted within the battery chamber. The battery receiving element includes a first set of contacts configured for a first battery type and a second contact configured for a second battery type and is movable between a first position in which the first set of contacts is exposed in the battery chamber and a second position in which the second contact is exposed in the battery chamber.
