Engineering Contradiction Analysis
1Loss of energy
If the hybrid generator uses both battery and generator power output, then the engine output can be reduced, but the user cannot easily ascertain the maximum amount of electric power that can be output
Solution Approach 1:
The system implements feedback by detecting the remaining battery amount and the generator's electric power generation capability, then notifying the user of the maximum output power. This closed-loop information feedback enables users to make informed decisions about power supply while the system optimizes engine operation based on actual power needs.
Solution Approach 2:
The hybrid generator automatically manages its own power distribution by detecting battery status and generator capability, calculating the maximum output power without requiring manual intervention. The system serves itself by autonomously determining optimal power allocation between battery and generator while providing users with relevant information.
2Adaptability or versatility
If the maximum electric power output varies according to battery capacity, then power supply flexibility is improved, but user convenience deteriorates due to inability to ascertain available power
Solution Approach 1:
The notification unit provides real-time feedback to users about the maximum electric power that can be output based on current battery capacity and generator status. This information feedback transforms the variable power output from an opaque parameter into transparent, actionable information for users.
Solution Approach 2:
The system performs preliminary detection of battery remaining amount and generator power capability before power supply operations. By calculating and notifying the maximum output power in advance, users can plan their power needs without uncertainty about available capacity.
