Accelerated Deterioration Testing with In-Test Product Collection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing accelerated deterioration test systems discharge products of sample deterioration to the outside, preventing the acquisition of the sample's deterioration state during the test.
Innovation Solution
An apparatus and method that includes a container with an introducer/collector to introduce deterioration factors and collect products of sample deterioration, allowing analysis of the sample's state while maintaining test conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the air and corrosive liquid are discharged to the outside of the test chamber during the accelerated deterioration test, then the test conditions can be maintained, but the products of sample deterioration cannot be collected for analysis
Solution Approach 1:
The invention extracts the harmful discharge function from the test chamber system by introducing a separate exhaust system that removes only the corrosive liquid and air, while the products of deterioration remain in the chamber for collection and analysis. This allows the test conditions to be maintained while preserving the deterioration information.
2Loss of information
If the products of sample deterioration are collected during the test, then the deterioration state can be analyzed, but the test conditions may be affected by the accumulated products
Solution Approach 1:
The invention segments the test chamber into functional zones: a test area where the sample deteriorates under controlled conditions, and a collection area where products are gathered. The exhaust system creates a directional flow that separates the corrosive atmosphere from the product accumulation zone, allowing both functions to occur simultaneously without interference.
Solution Approach 2:
The invention introduces an intermediary collection system that acts as a mediator between the test environment and the analysis system. This collection apparatus captures products of deterioration without disrupting the test conditions, serving as a buffer that allows continuous monitoring without affecting the acceleration process.
3Productivity
If the test chamber is sealed to maintain acceleration conditions, then the deterioration can be accelerated, but the products cannot be collected
Solution Approach 1:
The invention makes the test chamber system dynamic by implementing a controlled flow regime where corrosive liquid and air are continuously circulated to accelerate deterioration, while products are simultaneously removed through a dedicated collection pathway. This dynamic balance allows the chamber to remain effectively sealed for acceleration while enabling product collection.
