Testing Machine Liquid Collecting Device for Automated Moist Specimen Testing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing testing machines face challenges in maintaining automated operation over long periods without human intervention, particularly when testing moist or wet specimens, as liquid can escape and cause contamination or damage, especially in automated procedures.
Innovation Solution
A collecting device is integrated under the test specimen to collect any liquids that may drip during the testing process, which can be detachably connected to the lower clamping device and equipped with a drain line for continuous drainage, ensuring the testing machine operates safely and efficiently without operator intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If automated testing is performed over long periods without human supervision, then productivity increases, but liquid escaping from test specimens causes contamination and damage to the testing machine
Solution Approach 1:
A collecting device is introduced as an intermediary element between the test specimen and the testing machine environment. This device captures liquids escaping from the test specimen, preventing direct contact with and contamination of the testing machine components. The collecting device acts as a buffer zone that isolates the harmful liquid discharge from the sensitive testing environment.
Solution Approach 2:
The harmful liquid escaping from the test specimen is redirected into a useful function by channeling it into the collecting device. Instead of allowing the liquid to damage the testing machine, the system captures and contains it, potentially for measurement, analysis, or controlled disposal. The harmful discharge is transformed into a contained flow that serves the testing process.
2Reliability
If operator inspection and intervention are required to prevent contamination, then machine safety is maintained, but productivity decreases due to frequent interruptions
Solution Approach 1:
The testing system incorporates a self-service mechanism through the automatically operating collecting device that continuously prevents liquid contamination without requiring operator intervention. The device autonomously captures escaping liquids throughout the testing process, allowing the system to protect itself from damage while maintaining continuous operation and high productivity.
3Reliability
If a collecting device is added to prevent liquid contamination, then machine protection is improved, but device complexity increases
Solution Approach 1:
The collecting device is designed as a separate, modular component that can be independently installed and removed from the testing machine. This segmentation allows the protection function to be added without fundamentally redesigning the entire testing system. The modular nature enables easy integration while maintaining the simplicity of the core testing apparatus.
Solution Approach 2:
The collecting device serves multiple functions: it collects escaping liquids, prevents contamination of the testing machine, and can potentially measure or analyze the liquid properties. This multi-functionality justifies the added complexity by providing several benefits from a single added component rather than requiring separate systems for each function.
