Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the terminal device is kept in a receiving state all the time to implement functions like expense payment, then the function availability is improved, but the power consumption increases significantly
Solution Approach 1:
The patent implements periodic wake-up detection where the functional module alternates between sleep mode and active detection mode. The module periodically wakes up to detect sensor data (acceleration, gravity, proximity) and only activates the full receiving function when specific conditions are met, such as detecting that the device is in a payment-ready position. This periodic action pattern reduces power consumption while maintaining function availability.
Solution Approach 2:
The patent uses sensor data detection (acceleration, gravity, proximity sensors) as a preliminary action before activating the full functional module. The system pre-detects whether the device is in the correct state for payment (e.g., held at specific angle, near the payment terminal) and only then wakes up the ultrasonic receiving module. This preliminary detection avoids unnecessary full activation and reduces power consumption.
2Use of energy by moving object
If the terminal device is manually processed to turn on a payment interface, then the power consumption is reduced, but the user experience deteriorates
Solution Approach 1:
The patent implements self-service automation where the system automatically detects when payment conditions are met using sensor data (acceleration, gravity, proximity) and autonomously activates the payment interface without requiring manual user input. The device monitors its own state and automatically wakes up the functional module when it detects the device is held in the correct position near a payment terminal, providing both low power consumption and excellent user experience.
Solution Approach 2:
The system continuously monitors sensor data (acceleration, gravity, proximity) as feedback about the device's physical state and environment. When the feedback indicates payment-ready conditions (specific acceleration patterns, proximity to terminal), the system automatically triggers the payment interface activation. This feedback mechanism enables automatic, context-aware operation that improves user experience while avoiding unnecessary power consumption.
3Loss of energy
If the functional module is activated only when preset sensor conditions are met, then the power loss is reduced, but the response time may increase
Solution Approach 1:
The patent performs preliminary detection of sensor conditions (acceleration, gravity, proximity) continuously or at frequent intervals even when the main functional module is in sleep mode. This preliminary action prepares the system by having sensor data already available, so when a payment event occurs, the system can quickly determine if activation conditions are met without waiting for full sensor initialization, thus reducing response time while maintaining low power consumption.
Solution Approach 2:
The system uses periodic wake-up detection at optimized intervals, balancing power consumption and response time. The periodic detection frequency is tuned so that the module wakes up often enough to catch payment events quickly (reducing response time) but not so frequently that power consumption becomes significant. This optimized periodic action resolves the contradiction between power loss and response time.

AI summary
The present disclosure provides a method and apparatus for controlling a functional module, and a storage medium. The method includes: sensor data information of a sensor is acquired (S11); and the functional module is waked up to receive an ultrasonic signal in response to the acquired sensor data information meeting a preset condition (S12). In the method for controlling the functional module provided by the present disclosure, the wake-up condition of the functional module is set, i.e., in a case where the preset condition is met, the corresponding functional module is waked up to be in a working state, thereby reducing the power loss of the terminal and improving the user experience.
