Battery Terminal Shield Assembly With Movable Snap-Fit Caps
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrified vehicles lack effective protection for battery pack terminals, which are vulnerable to inadvertent contact during servicing, posing safety risks and potential damage.
Innovation Solution
A terminal shield assembly with movable terminal caps and anchoring sections, featuring snap-fit connections and retention systems, provides secure coverage and easy access to battery pack terminals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If terminal caps are made movable to allow easy access to terminals, then ease of operation is improved, but reliability of terminal protection deteriorates
Solution Approach 1:
The terminal caps are designed to be movable rather than fixed, allowing them to transition between a closed protective position and an open accessible position. This dynamic design enables the caps to provide reliable protection when closed while allowing easy access when opened, resolving the contradiction between protection reliability and operational ease.
Solution Approach 2:
The terminal protection system is segmented into separate movable caps for each terminal rather than a single fixed cover. This segmentation allows individual caps to be opened or closed independently, providing easy access to specific terminals when needed while maintaining protection for other terminals, thus balancing reliability and ease of operation.
2Adaptability or versatility
If multiple separate components are used for terminal protection, then adaptability is improved, but device complexity increases
Solution Approach 1:
Multiple terminal cap components are merged into a single integrated assembly that includes the anchoring section and multiple caps working together as one unit. This merging maintains the adaptability of individual caps while reducing overall assembly complexity through integrated design and simplified installation procedures.

AI summary
A battery pack terminal shield assembly includes an anchoring section, a first terminal cap connected to the anchoring section, and a second terminal cap connected to the anchoring section. The anchoring section is configured to secure the first terminal cap and the second terminal cap relative to an array of traction battery pack.
