Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing generator systems face issues with unnecessary power consumption and potential battery damage due to continuous external power supply when the generator operates in low or no-energy conditions, requiring a solution to efficiently wake up the microprocessor with minimal power usage.
Innovation Solution
A wake-up judgment apparatus is installed between the generator and microprocessor, utilizing a current-sensing element and electric charge processing element to determine if the microprocessor should be woken up, powered by an auxiliary micro power source that is significantly less than the main supply power, reducing power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the controller is continually supplied by external power to provide real-time response, then the controller can convert unstable energy into stable energy, but the controller accumulates unnecessary consumed power and may cause battery over-discharge or damage
Solution Approach 1:
The patent implements dynamic power supply mode switching, where the controller can operate in either full-power mode or wake-up judgment mode depending on system conditions. This allows the system to adapt its power consumption characteristics to actual operational needs, reducing unnecessary power usage while maintaining reliability when needed.
Solution Approach 2:
The patent introduces periodic wake-up judgment cycles where the microprocessor periodically wakes up to assess whether full operation is necessary. During intervals between wake-ups, the system operates in a low-power state, thereby reducing cumulative power consumption while still maintaining system reliability through periodic monitoring.
2Ease of operation
If the controller is operated in no-wind condition, no-water flow condition, or idle state for a long time with external power supply, then the controller can maintain readiness, but the battery might be over discharged or damaged
Solution Approach 1:
The patent implements preliminary wake-up judgment before full controller operation. The microprocessor performs preliminary assessments of system conditions (such as checking for no-wind or no-water flow conditions) and only activates full controller operation when necessary. This preliminary action prevents unnecessary battery power consumption during extended idle periods while maintaining the ability to quickly respond when conditions change.
3Adaptability or versatility
If the generator is operated from stationary condition to momentary condition and vice versa, then the generator can respond to changing energy conditions, but the controller cannot control to convert unstable energy into stable energy without continuous external power
Solution Approach 1:
The patent implements dynamic power supply adjustment that matches the generator's operational state. When the generator transitions between stationary and momentary conditions, the power supply to the controller is dynamically adjusted accordingly. Full external power is supplied only when the generator is actively producing energy that requires conversion, while reducing or eliminating power supply during stationary periods, thereby maintaining adaptability without continuous power consumption.
4Speed
If the generated mechanical energy from the generator suddenly occurs when the external energy is suddenly occurred, then the system can respond to energy availability, but the generated mechanical energy would damage the whole system or the controller
Solution Approach 1:
The patent implements preliminary wake-up judgment and system state assessment before allowing full operation. When external energy suddenly occurs, the microprocessor first wakes up to assess whether the generator is ready to produce mechanical energy and whether the controller is prepared to handle the energy conversion. This preliminary action prevents sudden energy surges from damaging the system by ensuring all components are in the appropriate state before energy transfer begins.
