Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional charging methods are used without accurate voltage detection, then charging process is simple, but battery charging accuracy deteriorates leading to overcharging or insufficient charging
Solution Approach 1:
The patent applies preliminary action by pre-setting multiple timing reference voltage ranges and their corresponding preset durations before charging begins. The controller stores these reference values in advance, allowing it to quickly compare the initial battery voltage against predetermined thresholds and determine the appropriate charging duration without complex real-time calculations, thus improving charging accuracy while maintaining simple control logic
Solution Approach 2:
The patent implements feedback by continuously monitoring the initial battery voltage and comparing it against stored timing reference voltage ranges. The controller uses this feedback to automatically select the appropriate preset duration for charging, creating a closed-loop control system that adjusts charging parameters based on actual battery state, thereby achieving precise charging control without excessive complexity
2Reliability
If charging duration is extended to ensure full charging, then charging completeness is improved, but risk of overcharging increases reducing battery endurance
Solution Approach 1:
The patent applies parameter changes by dynamically adjusting the charging duration parameter based on the initial battery voltage. Different initial voltage levels correspond to different preset durations stored in the controller. This ensures that batteries at different charge states receive appropriately tailored charging times, guaranteeing full charging while preventing overcharging, thus protecting battery endurance through precise parameter optimization
3Measurement precision
If multiple charging stages are implemented for different voltage ranges, then charging precision is improved, but control complexity increases
Solution Approach 1:
The patent reduces control complexity through preliminary action by pre-configuring multiple timing reference voltage ranges and their corresponding preset durations in the controller's memory before operation. During charging, the controller simply compares the measured initial voltage against these pre-stored thresholds and selects the matching preset duration, avoiding the need for complex multi-stage control logic while maintaining high voltage range detection accuracy
Solution Approach 2:
The patent applies segmentation by dividing the battery voltage range into multiple distinct timing reference voltage ranges, each associated with a specific preset duration. This segmentation allows the controller to handle different voltage scenarios as separate, manageable cases with predetermined solutions, simplifying the overall control process while achieving precise voltage range detection and appropriate charging duration selection

AI summary
An aerosol generation apparatus and a control method. The aerosol generation apparatus comprises a heater (10), a battery cell (20), a charging circuit and a controller, wherein the controller is configured to: acquire an initial voltage of the battery cell (20) when the battery cell starts to be charged; determine whether the initial voltage of the battery cell (20) is in one or more preset timing reference voltage intervals; and if the initial voltage of the battery cell (20) is in one timing reference voltage interval, according to a preset duration corresponding to the timing reference voltage interval, control the charging circuit to charge the battery cell (20), and when the charging duration for the battery cell (20) reaches the preset duration, control the charging circuit to stop charging the battery cell (20). Therefore, it is effectively ensured that a battery is fully charged but is not overcharged, thereby improving the endurance ability of the battery.
