Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If the system uses a fixed power source configuration, then the system structure is simple, but the power consumption is high during mode transitions
Solution Approach 1:
The patent implements dynamic power source switching by providing multiple power sources (first power source for normal mode, second power source for sleep mode) and using a control module to dynamically select between them based on operational mode. The power switch module dynamically connects or disconnects power sources, ensuring the system uses appropriate power sources for each operational state, thereby reducing power consumption during transitions while maintaining manageable system complexity through structured control.
2Loss of energy
If the system switches between different power sources, then the power conversion efficiency is improved, but the transition process consumes excessive power
Solution Approach 1:
The control module detects the operational mode in advance and proactively switches the power source configuration before the actual mode transition occurs. By using the operational mode signal to preemptively activate the appropriate power source, the system avoids high power consumption during the transition period, as the power switch module is already in the correct state when the mode change is initiated.
Solution Approach 2:
The system uses feedback from the operational mode signal to control the power switching process. The control module continuously monitors the operational mode and adjusts the power source configuration accordingly, creating a closed-loop control system that optimizes power consumption by responding to real-time operational conditions and ensuring efficient power source selection.
3Use of energy by moving object
If the system uses adaptive power source switching, then the power consumption is reduced, but the control system complexity increases
Solution Approach 1:
The patent segments the power control system into distinct functional modules: a power supply module with multiple power sources, a control module for detecting operational mode, and a power switch module for executing switching operations. This segmentation allows each module to perform its specific function independently, reducing overall control complexity while achieving adaptive power source switching and reduced power consumption through coordinated module operation.
