Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If preset threshold levels are set high to prevent sudden voltage drops and device shutdowns, then device reliability is improved, but system efficiency deteriorates due to excessive voltage levels
Solution Approach 1:
The system continuously monitors electrical consumption and uses this feedback to dynamically adjust voltage levels. The controller receives real-time consumption data and adjusts the transformer tap position accordingly, creating a closed-loop control system that responds to actual load conditions rather than relying on fixed high thresholds.
Solution Approach 2:
The patent transitions from static preset threshold levels to dynamic voltage adjustment based on real-time consumption monitoring. The system adapts voltage levels continuously according to varying electrical load conditions, allowing optimal voltage maintenance without the energy losses associated with consistently high voltage settings.
2Stability of the object's composition
If frequent tap changes are implemented to maintain voltage levels, then voltage stability is improved, but tap mechanism reliability deteriorates due to increased failure rate
Solution Approach 1:
The continuous monitoring of electrical consumption provides feedback that enables proactive voltage management. The system detects consumption trends and adjusts tap positions before voltage instability occurs, reducing the frequency of reactive tap changes and thereby extending tap mechanism life while maintaining voltage stability.
Solution Approach 2:
The system performs preliminary voltage adjustments based on consumption patterns before actual voltage deviations occur. By monitoring electrical consumption continuously, the controller can anticipate voltage changes and adjust tap positions in advance, preventing the need for frequent corrective tap changes.
3Device complexity
If preset threshold levels are used for voltage control, then system simplicity is maintained, but adaptability to changing electrical loading deteriorates
Solution Approach 1:
The system incorporates continuous consumption monitoring that provides real-time feedback to the controller. This feedback mechanism enables the system to automatically adapt to changing electrical load conditions without requiring complex manual reconfiguration, achieving adaptability through automated responsive control based on actual consumption data.
Data Source
AI summary
A method and apparatus for controlling electric power supplied to one or more electrical devices from a power source are disclosed. Measurements of the supplied electricity are detected. Estimated deviant voltage levels that the supplied electricity will not drop below or exceed as a result of varying electrical consumption by the one or more electrical devices is computed based on a predetermined confidence level and the detected measurements. A voltage level output of the electricity supplied to the electrical device is adjusted based on the computed deviant voltage level.
