Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional delay circuits are used without voltage stabilization, then the circuit structure is simple, but the delay accuracy deteriorates due to temperature and voltage fluctuations
Solution Approach 1:
A linear voltage stabilization unit is introduced as an intermediary component between the power supply and the delay unit. This unit receives a reference voltage and generates a stabilized power supply control signal, which is then provided to the delay unit. The intermediary stabilizes the voltage fluctuations that would otherwise affect delay accuracy, resolving the contradiction by adding a dedicated stabilization component rather than attempting to make the entire circuit more complex.
Solution Approach 2:
The invention changes the voltage parameter through the linear voltage stabilization unit, which adjusts and stabilizes the power supply control signal based on a reference voltage. By dynamically adjusting the voltage parameter to remain stable despite external fluctuations, the delay accuracy is maintained without requiring fundamental changes to the overall circuit architecture.
2Measurement precision
If temperature compensation mechanisms are added to delay circuits, then delay accuracy improves, but device complexity increases
Solution Approach 1:
The linear voltage stabilization unit changes the voltage parameter to compensate for temperature effects. By stabilizing the power supply control signal against temperature-induced variations, the delay accuracy is improved without requiring separate temperature sensing or compensation circuits, thus avoiding increased device complexity.
3Measurement precision
If voltage stabilization is implemented in delay circuits, then delay accuracy improves, but power consumption increases
Solution Approach 1:
The linear voltage stabilization unit acts as an intermediary that efficiently manages power consumption. By stabilizing the voltage at the appropriate point in the circuit, it prevents power waste that would occur from voltage fluctuations affecting the delay unit, thereby achieving both improved accuracy and reasonable power consumption management.
Solution Approach 2:
The voltage stabilization unit dynamically adjusts the power supply control signal parameter to maintain optimal operating conditions. This parameter adjustment ensures that the delay unit receives stable voltage without excessive power consumption, as the stabilization is applied only where needed rather than throughout the entire circuit.
