Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the reference voltage circuit uses a fixed configuration with all transistors and resistors connected to power supply terminals, then precise and stable reference voltage output is achieved, but current consumption cannot be reduced in low power modes
Solution Approach 1:
The patent applies dynamics by making the reference voltage circuit configuration changeable through switching elements. The circuit can dynamically reconfigure itself between different operation modes (normal mode with full precision, low current mode with reduced configuration) by controlling the switching elements to connect or disconnect specific transistors and resistors from the power supply terminals, thus resolving the contradiction between maintaining precision and reducing current consumption.
Solution Approach 2:
The patent changes the operational parameters of the circuit by controlling the switching elements to alter which components are active. In normal operation mode, all components operate with full power supply connection for maximum precision. In low current consumption mode, the switching elements disconnect certain transistors and resistors from power supply terminals, changing the circuit parameters to reduce current while maintaining acceptable reference voltage output.
2Stability of the object's composition
If the reference voltage circuit maintains a complete configuration for precise voltage output, then stability is improved, but the circuit cannot adapt to different operation modes requiring different current consumption levels
Solution Approach 1:
The switching elements enable the circuit to dynamically adapt its configuration based on operation mode requirements. The circuit maintains stability in each mode by ensuring proper connection of essential components while allowing adaptability between modes through the controlled connection and disconnection of non-essential components, thus resolving the contradiction between stability and adaptability.
Solution Approach 2:
The reference voltage circuit is designed with multi-functionality to serve different operation modes. The same circuit structure can operate in normal mode with full precision and stability, or in low current consumption mode with reduced configuration, making the circuit universal across different operational requirements without needing separate dedicated circuits for each mode.
