Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If full power is provided to each terminal device, then device functionality is improved, but system power consumption increases and power allocation efficiency deteriorates
Solution Approach 1:
The patent implements dynamic power class assignment by changing the power parameters provided to different terminal devices based on their actual needs. The central power supply unit determines appropriate power classes for each device and adjusts power delivery accordingly, rather than providing full power to all devices. This resolves the contradiction by enabling full functionality for devices that need it while reducing power consumption for devices with lower requirements.
2Reliability
If power is provided to all terminal devices, then device operation is ensured, but power allocation efficiency and resource utilization deteriorate
Solution Approach 1:
The patent applies local quality by providing different power levels to different terminal devices based on their individual characteristics and requirements. Each device receives a customized power allocation determined by the central power supply unit, which assesses device needs and assigns appropriate power classes. This ensures reliable operation for all devices while optimizing overall power allocation efficiency.
3Object-affected harmful factors
If minimal power is provided during detection phase, then device safety is improved, but power availability for functionality activation deteriorates
Solution Approach 1:
The patent implements preliminary action by conducting a detection and classification phase before full power delivery. During this initial phase, minimal power is provided to safely detect device presence and determine power class requirements. Once device characteristics are known, the system transitions to providing appropriate power levels, thus preventing device damage while ensuring sufficient power availability for required functionalities.
4Ease of operation
If power classes are strictly enforced, then power management control is improved, but device functionality and energy utilization deteriorate
Solution Approach 1:
The patent applies dynamics by making power class assignment flexible rather than rigid. While the system uses power classes as a framework for power management control, it dynamically adjusts power allocation based on actual device requirements, available power resources, and functional needs. This dynamic approach maintains good power management control while enabling adaptable device functionality.
