Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery fixation systems in vehicles face issues with excessive loads causing damage to batteries and potential leakage due to vibrations, leading to instability and failure of the fixing system.
Innovation Solution
A fixation system using a cover and levers with compensable length connections and elastic means to provide a stable and compact fixation, avoiding excessive stresses by allowing for adjustable compression loads.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If bolts are tightened to fix batteries in the pack, then batteries are secured against movement, but excessive load stresses damage batteries and cause fluid leakage
Solution Approach 1:
The invention introduces a cushioning element positioned between the battery and the fixing lever. This cushioning element absorbs and distributes the mechanical stress generated during vibration, preventing excessive loads from being transmitted directly to the battery structure. By providing this protective buffer in advance, the system maintains reliable fixation while protecting battery integrity and preventing electrolyte leakage.
2Stability of the object's composition
If rigid fixation is used to secure batteries, then movement is prevented, but vibration stresses cause damage and leakage
Solution Approach 1:
The cushioning element functions as a flexible component that replaces rigid fixation with a compliant connection. This flexible element maintains stable battery positioning while accommodating vibration-induced movements through elastic deformation, thereby preventing the transmission of harmful stress concentrations to the battery structure and eliminating the risk of vibration-induced damage and leakage.
