Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery fastening systems in vehicles are not adaptable to various battery sizes and require multiple designs for different sizes, leading to increased complexity and cost in manufacturing, storage, and installation.
Innovation Solution
A battery fastening system comprising a battery tray with L-shaped corner fastening devices and a slidingly moveable clamping element, allowing for secure attachment of batteries of different sizes by adjusting the clamping element's position along an elongated slot, and enabling secure locking in multiple positions to accommodate various dimensions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single battery fastening system design is used for various battery sizes, then adaptability is improved, but securing reliability may worsen due to size variations
Solution Approach 1:
The fastening system incorporates movable and adjustable components including sliding clamps that can be positioned at different locations along the battery tray, and corner fastening devices that can be adjusted to accommodate different battery dimensions. This dynamic adjustability allows the same fastening system to reliably secure batteries of various sizes while maintaining proper fastening force and security.
2Adaptability or versatility
If multiple fastening positions are provided for different battery sizes, then adaptability is improved, but device complexity worsens
Solution Approach 1:
The fastening system uses universal multi-functional components that can serve multiple positioning requirements. The sliding clamps can move along the battery tray to engage with batteries of different lengths, while the corner fastening devices can be adjusted to accommodate different battery widths and heights. This multi-functionality allows a single fastening system design to handle various battery sizes without requiring multiple specialized fastening devices for each size category.
