Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If temperature sensors are tested manually and sequentially, then each sensor can be tested individually, but the testing process becomes time-consuming and causes temporary plant shutdowns
Solution Approach 1:
The patent merges multiple individual sensor testing operations into a single simultaneous testing process. The heating device applies thermal stimulus to all sensors on the mold surface at the same time, and the evaluation electronics process all sensor signals concurrently, transforming sequential testing into parallel testing to dramatically reduce total testing time.
Solution Approach 2:
The patent replaces manual mechanical testing procedures with an automated electronic testing system. The heating device provides controlled thermal stimulation, while evaluation electronics automatically capture and analyze temperature signals from all sensors simultaneously, eliminating the need for manual intervention and significantly accelerating the testing process.
2Measurement precision
If temperature sensors are tested manually, then individual sensor functionality can be determined, but the mold cannot be used to produce melt during testing
Solution Approach 1:
The patent replaces time-consuming manual testing with an automated electronic testing system that operates rapidly and concurrently for all sensors. This automation enables the testing process to be completed quickly enough that the mold can be returned to production use almost immediately, thereby maintaining high mold utilization while still ensuring accurate sensor functionality assessment.
3Measurement precision
If temperature sensors are tested sequentially, then each sensor can be evaluated individually, but maintenance costs increase due to prolonged system downtime
Solution Approach 1:
The patent combines individual sensor evaluation capabilities with simultaneous testing of all sensors. The evaluation electronics are configured to process signals from multiple sensors at the same time, maintaining the ability to assess each sensor's measurement characteristics individually while completing the entire testing process in a single operation, thereby minimizing downtime and reducing maintenance costs.
