Battery Disconnect Unit Moving Plate for Flexible Part Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional battery disconnect units require new housing development when electric part sizes change, leading to increased development expenses and reduced profitability due to fixed insert bolt positions.
Innovation Solution
A battery disconnect unit with a moving plate that allows adjustable positioning within a housing, enabling the same housing to accommodate electric parts of varying sizes by using a housing with an insertion portion and multiple fastening holes for flexible mounting of relays and sensors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the position of the insert bolt is fixed in the housing, then the housing structure is simple and easy to manufacture, but the housing cannot accommodate electric parts of different sizes, requiring new housing development
Solution Approach 1:
The insert bolt is designed to be movable along the housing wall rather than fixed at a single position. The housing includes multiple insertion portions at different locations, allowing the insert bolt to be positioned flexibly depending on the size of the electric part being mounted. This dynamic positioning capability enables the same housing to accommodate various sized electric parts without requiring new housing designs.
2Ease of manufacture
If new housing is developed for each electric part size, then the housing can perfectly fit the specific electric part, but development expenses increase and profitability decreases
Solution Approach 1:
The housing is designed as a universal structure with multiple insertion portions that can accommodate different sizes of electric parts (relays, sensors, etc.). Instead of developing separate housings for each electric part size, a single housing design with multiple positioning options serves multiple functions. This universality reduces the number of housing variants needed, thereby reducing development expenses and improving manufacturing efficiency.
3Adaptability or versatility
If multiple insert bolts are provided at different positions, then electric parts of different sizes can be mounted, but the housing structure becomes more complex
Solution Approach 1:
The housing wall is segmented into multiple insertion portions at different locations. Each insertion portion can independently receive an insert bolt. This segmentation allows the housing to provide multiple mounting positions without requiring a completely complex redesign, as each insertion portion is a relatively simple structural element that can be independently configured.
