Parallel Measurement Device with Pre-Driven Detectors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing measurement devices face increased measurement time when simultaneously measuring electrical resistance and other physical properties, as the operation of the second measurement unit is delayed relative to the first unit, leading to prolonged overall measurement time.
Innovation Solution
A measurement device configuration where the second measurement unit starts its detector driving before the first unit, and both units execute measurements in parallel with the resistance measurement unit, with the control unit managing these operations to reduce noise influence and optimize measurement timing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the detector in the second measurement unit is started after the detector in the first measurement unit, then the operation sequence is simplified, but the measurement time increases
Solution Approach 1:
The detector in the second measurement unit is started before the actual measurement begins, performing preliminary initialization and warm-up. This preliminary action ensures that when the measurement starts, both detectors are already in a ready state, allowing parallel measurement operations and reducing total measurement time while maintaining operational simplicity.
2Productivity
If both measurement units operate in parallel with the resistance measurement unit, then measurement efficiency improves, but measurement time may increase due to coordination complexity
Solution Approach 1:
The second measurement unit performs preliminary detector startup and initialization before the parallel measurement operation begins. This ensures that when all units operate in parallel, the detectors are already calibrated and ready, avoiding delays in coordination and maximizing measurement efficiency without increasing total measurement time.
Solution Approach 2:
The measurement system maintains continuous useful action by having the second measurement unit's detector already operational and ready before the parallel measurement starts. This continuity eliminates idle waiting periods and ensures that all measurement operations proceed simultaneously without interruption, optimizing both productivity and time efficiency.
3Loss of time
If the second measurement unit starts detector driving before the first unit, then measurement time is reduced, but noise interference may increase
Solution Approach 1:
The second measurement unit's detector is started in advance for preliminary initialization, but the actual measurement operation is triggered only after the first measurement unit begins. This timing coordination ensures that noise from the resistance measurement unit does not interfere with the second measurement unit's detector, while still allowing both units to operate in parallel and reduce total measurement time.
Solution Approach 2:
The control unit monitors the operational status of both measurement units and coordinates their startup sequences. It uses feedback information about when each detector is ready and when noise levels are acceptable to optimize the timing of measurement operations, reducing noise interference while maintaining parallel operation efficiency.
