Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If ripple control technology is used to manage power transmission, then power distribution control is achieved, but device complexity and investment costs increase due to specialized transmitters/receivers and communication infrastructure
Solution Approach 1:
The patent enables energy consumers and producers to autonomously monitor electrical variables (frequency, voltage) and self-regulate their power transmission without external control signals. The system uses inherent grid parameters as feedback, eliminating the need for specialized ripple control transmitters and receivers, thereby reducing device complexity while maintaining reliable power distribution control
Solution Approach 2:
The patent implements a feedback mechanism where the control unit continuously monitors electrical variables (frequency, voltage) of the power supply network and automatically adjusts power transmission based on detected deviations from nominal values. This inherent feedback loop replaces complex external communication infrastructure by using the grid's own electrical parameters as control signals
2Ease of operation
If charging devices operate without considering network load conditions, then charging simplicity is maintained, but network stability deteriorates during peak loads
Solution Approach 1:
The charging device autonomously monitors network electrical variables and self-regulates its power consumption without requiring external control signals or complex user intervention. The control unit automatically reduces charging power when frequency or voltage deviations indicate peak load conditions, maintaining both operational simplicity and network stability
Solution Approach 2:
The patent implements automatic feedback control where the charging device continuously monitors network frequency and voltage, and adjusts its power consumption accordingly. When deviations from nominal values are detected, the control unit automatically reduces charging power, creating a self-regulating system that maintains network stability without complex external control
3Reliability
If power transmission is continuously adjusted based on electrical variables, then network stability is improved, but control system complexity increases
Solution Approach 1:
The patent uses the power supply network's own electrical variables (frequency, voltage) as feedback signals. The control unit monitors these inherent grid parameters and automatically adjusts power transmission based on detected deviations from nominal values, creating a simple yet effective feedback control system that improves network stability without adding complex control infrastructure
Solution Approach 2:
The patent uses electrical variables (frequency, voltage) as intermediary signals that carry information about network load conditions. These inherent electrical parameters serve as natural mediators between the power network state and the power transmission control, eliminating the need for complex communication systems while enabling automatic stability control
