Battery Disconnect Unit With Movable Plate for Part Size Variations
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional battery disconnect units require new housings when electric parts of varying sizes are used, leading to increased development expenses and reduced profitability.
Innovation Solution
A battery disconnect unit with a movable moving plate that can be positioned flexibly within a housing to accommodate electric parts of different sizes, using a housing with insertion and fastening portions to secure the moving plate and electric parts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the position of the insert bolt is fixed in the housing, then the structure is simple, but a new housing must be developed when the size of electric parts is changed, increasing development expenses
Solution Approach 1:
The housing structure is segmented into a fixed housing body and a movable plate that can be repositioned. The insert bolt is attached to the movable plate rather than being fixed to the housing body, allowing the plate to be moved to different positions to accommodate different electric part sizes while keeping the main housing structure simple and reusable
Solution Approach 2:
The insert bolt position is made dynamic through the movable plate mechanism. The plate can be moved to different positions within the housing and fixed at each position, transforming the static bolt position into a dynamic, adjustable position that adapts to different electric part sizes without requiring a new housing design
2Adaptability or versatility
If a new housing is developed for each electric part size, then the electric part can be properly mounted, but development expenses are increased and profitability is reduced
Solution Approach 1:
A single housing design serves multiple functions by accommodating different electric part sizes through the movable plate mechanism. The housing itself remains universal and reusable, while the movable plate provides the adaptability needed for different configurations, eliminating the need to develop new housings for each electric part size and reducing manufacturing costs
