Engineering Contradiction Analysis
1Measurement precision
If semiconductor integrated circuits are used to control safety voltage, then voltage control precision is improved, but device complexity and instability increase
Solution Approach 1:
The patent extracts the essential function of voltage control from complex semiconductor integrated circuits and implements it using a simple resistor divider circuit. By taking out only the necessary voltage division function and implementing it with passive components (resistors), the solution achieves voltage control without the complexity and instability of integrated circuits.
Solution Approach 2:
The patent replaces expensive and complex semiconductor integrated circuits with inexpensive, simple resistor components. Although resistors have limited functional capability compared to integrated circuits, they provide sufficient voltage control for safety functions while being much simpler, more reliable, and cost-effective.
2Adaptability or versatility
If complex control algorithms are used to set safety voltage, then voltage level adjustment flexibility is improved, but system stability and ease of manufacture worsen
Solution Approach 1:
The patent achieves voltage level adjustment by changing physical parameters of the resistor divider circuit (resistance values) rather than using complex control algorithms. By selecting different resistance values, the safety voltage level can be adjusted to meet different standards while maintaining system simplicity and stability.
3Extent of automation
If integrated circuits are used for safety voltage control, then automation is improved, but power loss and system burden increase
Solution Approach 1:
The resistor divider circuit operates passively without requiring active control or additional power input. The circuit automatically provides the safety voltage through passive voltage division, eliminating the power consumption and heat generation associated with active semiconductor control circuits.
