Adjustable Battery Gas Collection Chamber for High-Concentration Sampling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional gas collecting apparatuses face difficulties in efficiently collecting high-concentration gas from batteries with varying specifications due to the need for individual diffusion chambers, which complicates manufacturing, installation, and gas concentration analysis.
Innovation Solution
A gas collecting apparatus comprising a lower jig, an upper jig, a lower housing, and an upper housing, where the jigs are designed to accommodate batteries of different specifications, ensuring a secure and adjustable fit within a closed space, allowing for easy mounting, replacement, and gas collection without gaps, utilizing Teflon materials for low friction and chemical resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If individual diffusion chambers are used for each battery specification, then gas collection accuracy is improved, but device complexity and manufacturing difficulty increase
Solution Approach 1:
The patent employs a universal diffusion chamber that can accommodate multiple battery types and specifications through adjustable positioning mechanisms. The chamber includes a movable platform with clamps that can be adjusted to fit different battery sizes, eliminating the need for separate chambers for each battery specification while maintaining accurate gas collection
2Adaptability or versatility
If diffusion chamber size is increased to accommodate various batteries, then adaptability is improved, but gas concentration decreases
Solution Approach 1:
The diffusion chamber is divided into adjustable segments and zones that can be configured to match the battery size. The movable platform can be positioned at different locations within the chamber, and sealing elements can be adjusted to create an optimal sealed volume around the battery, maintaining high gas concentration while accommodating various battery specifications
3Productivity
If tight sealing is implemented to collect high-concentration gas, then gas collection efficiency is improved, but battery removal difficulty increases
Solution Approach 1:
The sealing system incorporates movable and adjustable components rather than fixed rigid seals. The platform can be dynamically repositioned, and clamps can be adjusted to provide secure sealing during gas collection while allowing easy release and removal of the battery after testing. The sealing force can be modulated to balance between secure sealing and easy removal
