Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a control device obtains measured values based on clock time to control physical parameter application units, then the control effectiveness is improved, but the device complexity increases due to the need for timer integration and mathematical relation determination
Solution Approach 1:
The patent combines the timer function and processing unit into an integrated control device. The timer and processing unit work together as a unified system to sense clock time, generate sense signals, and determine mathematical relations between measured values and application ranges, thereby improving control effectiveness while managing device complexity through functional integration
Solution Approach 2:
The control device is designed with multi-functionality to handle various physical parameter application units (motors, relays, energy converters). The processing unit can determine different mathematical relations for different application ranges, and the device can control different types of physical parameters, making it a universal control solution that addresses multiple control scenarios
2Measurement precision
If the processing unit determines the current clock time application interval by checking mathematical relations, then the measurement precision is improved, but the loss of time increases due to the computational processing required
Solution Approach 1:
The timer is configured to sense clock time and generate sense signals in advance, preparing the data before it is needed for control decisions. The processing unit determines mathematical relations between measured values and application ranges beforehand, so when control actions are required, the precise measurements are already available, reducing the time loss during actual control operations
