Solution Overview
Problem
Mobile laboratory safety workbenches require frequent installation tests after changes in location, which are time-consuming and costly, due to the need to check for leaks caused by movement, such as during transportation or exposure to shock loads.
Innovation Solution
A safety workbench with a measuring arrangement that detects impact loads in three spatial directions and compares them to maximum permissible limits, allowing for the reduction of unnecessary installation tests by signaling when the limits are exceeded, thereby saving time and resources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If installation tests are performed after every relocation of the mobile laboratory, then safety and reliability are ensured, but time and cost expenditure increase significantly
Solution Approach 1:
The safety workbench performs self-diagnosis through integrated sensors and evaluation units that automatically monitor impact loads, seal conditions, and operational parameters. The system generates its own diagnostic data and determines when installation tests are necessary, eliminating the need for manual inspection after every relocation and reducing time expenditure while maintaining safety
Solution Approach 2:
The system continuously monitors impact loads, seal conditions, and operational parameters, comparing real-time data against predefined thresholds. When abnormal conditions are detected, the system provides feedback signals to alert operators and automatically schedules necessary installation tests, ensuring safety while minimizing unnecessary test frequency and associated time costs
2Reliability
If installation tests are performed after every relocation of the mobile laboratory, then safety and reliability are ensured, but cost expenditure increases significantly
Solution Approach 1:
The safety workbench autonomously monitors its own condition through integrated sensors and evaluation systems, generating diagnostic data that determines when installation tests are truly necessary. This self-service capability eliminates wasteful spending on routine tests after every relocation while ensuring tests are performed when actually needed for safety, thereby reducing overall cost expenditure
Solution Approach 2:
The system continuously feeds back diagnostic information from sensors monitoring impact loads, seal conditions, and operational parameters. This feedback mechanism enables cost-effective operation by triggering installation tests only when abnormal conditions are detected, rather than performing expensive tests after every relocation, thus optimizing the balance between safety and cost
3Measurement precision
If comprehensive installation tests are performed frequently, then leak detection accuracy is improved, but productivity decreases
Solution Approach 1:
The system performs preliminary monitoring of impact loads, seal conditions, and operational parameters continuously during normal operation. By detecting potential leak conditions in advance through this preliminary action, the system can schedule targeted installation tests only when necessary, maintaining high leak detection accuracy while avoiding the productivity loss associated with frequent comprehensive testing
Solution Approach 2:
The system provides continuous feedback on seal integrity and impact load conditions, enabling early detection of potential leak issues. This feedback mechanism allows for precision leak detection when actually needed while maintaining high productivity by avoiding unnecessary frequent comprehensive tests, as the system only triggers installation tests when abnormal conditions are detected
