Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Desulfurizers used in battery packs with sulfide-based batteries face significant stress during transportation due to vertical vibrations, which can compromise their structural integrity and hydrogen sulfide removal efficiency.
Innovation Solution
A hydrogen sulfide removal unit with baffle plates angled within 10° from the vertical direction, forming a meandering flow passage, and a distribution port at the lower part of the baffle plates, enhancing structural strength and hydrogen sulfide removal efficacy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional partition plates joined to top or bottom surfaces are used, then the desulfurizer structure is simple, but the strength against vertical stress during transport is insufficient
Solution Approach 1:
The baffle plate is rotated from a horizontal configuration (joined to top/bottom surfaces) to a vertical configuration (connecting side surfaces), changing the dimensional orientation of the structural element to better resist vertical stress during transport
2Productivity
If baffle plates are oriented horizontally, then manufacturing is simple, but hydrogen sulfide removal efficiency is reduced under vibrational conditions
Solution Approach 1:
The baffle plate orientation is changed from horizontal to vertical, creating a meandering flow passage that maintains desulfurization efficiency under vibrational conditions by preventing direct gas flow paths
Solution Approach 2:
The vertical baffle plate configuration creates a curved/meandering flow path for the gas, replacing straight horizontal flow with a more complex three-dimensional flow pattern that enhances contact time and removal efficiency
