Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the mobile power supply terminal is completely turned on according to the normal turn-on mode, then the terminal can supply power to the to-be-charged device, but the startup time is long and the terminal cannot charge quickly
Solution Approach 1:
The power supply mode is segmented into a complete turn-on mode and a quick charge mode. In the quick charge mode, only the power supply functional module is activated while other functional modules remain inactive, dividing the system operation into independent controllable segments that can be selectively activated based on charging needs.
Solution Approach 2:
Instead of activating all functional modules during charging, the system applies partial action by activating only the necessary power supply module. This reduces the startup time and resource consumption while still achieving the charging function, avoiding the excessive activation of unnecessary modules.
2Power
If the mobile terminal is completely turned on to charge an external device, then power can be supplied, but many power-consuming functional modules are turned on causing large power consumption
Solution Approach 1:
The system segments the functional modules into power supply module and other functional modules (communications, display, etc.). During charging, only the power supply module is activated while other modules remain inactive, allowing independent control of power consumption for each segment.
Solution Approach 2:
The unnecessary functional modules are extracted or removed from the active state during charging operations. The system extracts only the essential power supply function while leaving other modules in a low-power or inactive state, thereby reducing overall power consumption.
3Power
If the mobile terminal charges an external device while in a complete turn-on state, then power can be supplied, but the terminal also consumes electricity itself causing large current and high temperature
Solution Approach 1:
The system extracts and isolates the power supply function from other functional modules during charging. By taking out only the necessary power supply module and keeping other modules inactive, the overall current draw is reduced, which directly lowers heat generation and battery temperature during charging operations.
Solution Approach 2:
The system converts the potential harm of high current and heat generation into a benefit by selectively activating only the power supply module. This controlled activation transforms what would be a harmful high-power state into a controlled, efficient charging state with minimized heat generation.
4Adaptability or versatility
If the mobile terminal supplies power outwards in startup state and turns on another functional module, then additional functions are available, but the current becomes large and power supply becomes unstable
Solution Approach 1:
The system segments functional modules into power supply module and other functional modules, allowing independent control. During charging, only the power supply module is activated to maintain stable power output, while other modules can be selectively activated only when power supply stability is not compromised.
Solution Approach 2:
The system dynamically adjusts the activation state of functional modules based on power supply requirements. When charging is detected, the system dynamically activates only the power supply module to ensure stability, and can dynamically add other modules later if needed and if power stability is maintained.

AI summary
The present invention discloses a mobile power supply terminal and a power supply method thereof, which are designed for solving problems such as a long readiness time from a shutdown state to outward power supply, and large power consumption of the mobile power supply terminal during the power supply, due to that the existing mobile power supply terminal can supply power outwards only in a startup mode. For the mobile power supply terminal, a trigger circuit and a control circuit are added to a conventional device. After a to-be-charged device is connected to the mobile terminal, one end of a power supply interface generates a level signal, to make the trigger circuit generate a trigger signal; and then the control circuit controls, according to the trigger signal, the mobile power supply terminal to enter a power supply mode, and controls a power supply source to charge the to-be-charged device by using the power supply interface. The mobile power supply terminal and the power supply method thereof in the present invention feature simple hardware structure, and easy implementation, and short charging preparation time, which are also beneficial to prolong standby duration and a service life of the power supply source.
