Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If internal voltage generators are continuously enabled to maintain stable internal voltages, then voltage stability is improved, but current consumption increases
Solution Approach 1:
The patent applies periodic action by enabling the internal voltage generator only during specific periods when internal voltages are actually needed, rather than keeping it continuously enabled. The controller activates the voltage generator in response to detecting that an internal voltage is needed, and disables it when not needed, creating a periodic on/off pattern that reduces current consumption while maintaining voltage stability during active periods
Solution Approach 2:
The patent implements self-service through the voltage detection mechanism that automatically determines when internal voltages are needed. The controller monitors the internal voltage status and autonomously activates or deactivates the voltage generator based on actual demand, eliminating the need for continuous operation while ensuring voltage stability is maintained when required
2Use of energy by moving object
If internal voltage generators are disabled to reduce current consumption, then power consumption decreases, but voltage stability deteriorates
Solution Approach 1:
The patent employs feedback through the voltage detection mechanism that continuously monitors whether internal voltages are needed. This feedback loop allows the controller to make informed decisions about when to activate or deactivate the voltage generator, ensuring that voltage stability is maintained during periods when voltages are needed while allowing power consumption to decrease during periods when voltages are not required
3Reliability
If voltage generation circuit operates continuously to ensure reliable voltage supply, then voltage availability is improved, but overall power consumption increases
Solution Approach 1:
The patent applies periodic action by operating the voltage generation circuit only during specific periods when internal voltages are actually needed. The controller activates the voltage generator in response to detecting voltage needs and disables it when not needed, creating a periodic operation pattern that ensures voltage availability during active periods while reducing energy loss during inactive periods
Solution Approach 2:
The patent implements dynamics by making the voltage generation circuit's operation state variable rather than fixed. The controller dynamically adjusts the voltage generator's enabled/disabled state based on real-time detection of internal voltage needs, allowing the system to adapt its power consumption level to actual operational requirements while maintaining voltage availability when needed

AI summary
A voltage generation circuit includes: a periodic wave generator that generates an on/off signal that is periodically enabled/disabled, where at least one between a period and a duty cycle of the on/off signal is controlled based on at least one information among temperature information, capacitance information, leakage current information, speed information, and voltage level information; and an internal voltage generator that is enabled/disabled in response to the on/off signal and generates an internal voltage.
