Battery Accommodation Structure Using Clamping Spring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery accommodation structures require additional holding members or covers to securely hold batteries, increasing costs and complexity.
Innovation Solution
A battery accommodation structure that uses a clamping spring to securely hold batteries within an accommodation case, eliminating the need for external holding members or covers by clamping the battery's outer peripheral surface, and includes terminal springs to facilitate easy installation and detachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a cover is attached after battery accommodation to support the battery, then the battery can be stably held, but additional holding members or a specially designed cover are required, increasing costs and complexity
Solution Approach 1:
The patent combines the battery holding function with the terminal structure by integrating a clamping spring into the terminal assembly. The terminal includes both electrical contact functionality and mechanical clamping functionality, eliminating the need for separate holding members or covers. This merging of functions reduces structural complexity while maintaining reliable battery retention.
2Reliability
If a cover is attached after battery accommodation to support the battery, then the battery can be stably held, but additional holding members or a specially designed cover are required, increasing costs
Solution Approach 1:
The terminal structure is designed to perform both electrical connection and mechanical retention functions simultaneously. The clamping spring is integrated into the terminal assembly, allowing a single component to replace what would traditionally require multiple separate parts (terminal + holding member/cover), thereby reducing manufacturing costs.
Solution Approach 2:
The terminal is designed as a multi-functional component that provides both electrical contact and mechanical clamping. This universal design allows one component to fulfill multiple roles, eliminating the need for additional specialized holding members or covers, thus reducing overall manufacturing costs.
3Ease of operation
If terminal springs are used to facilitate easy installation and detachment, then battery installation is simplified, but the terminal structure becomes more complex
Solution Approach 1:
The terminal incorporates a spring mechanism that provides dynamic, flexible contact rather than rigid fixed contact. The spring allows the terminal to automatically adjust to battery position variations and provides easy installation through spring-loaded engagement, while the spring itself is a simple, well-understood mechanical element that doesn't significantly increase overall complexity.

AI summary
A battery accommodation structure includes, in an accommodation case configured to accommodating a battery, a positive electrode terminal, a negative electrode terminal, and a clamping spring. The positive electrode terminal is connected to a positive electrode of the battery. The negative electrode terminal is connected to a negative electrode of the battery. The clamping spring is provided between the positive electrode terminal and the negative electrode terminal and clamps a part of an outer peripheral surface of the battery. Thus, it is possible to accommodate the battery without supporting the battery with a cover to be attached after the accommodation of the battery, using a holding member or the like.
