Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If voltage converter operates continuously to supply DC voltage, then power supply is maintained, but energy consumption increases due to low efficiency operation
Solution Approach 1:
The voltage converter operates periodically rather than continuously. The control unit monitors the charge state of the energy storage element and activates the voltage converter only when the energy storage element's charge drops below a threshold level, creating periodic charging cycles that reduce overall energy consumption while maintaining power supply reliability
Solution Approach 2:
The energy storage element is charged in advance during periods of low demand or high efficiency operation, so that power is already available when needed. This preliminary charging action allows the system to avoid continuous converter operation and reduces peak demand on the voltage converter
2Reliability
If separate power cable and data cable are used, then power and data transmission are reliable, but installation complexity increases
Solution Approach 1:
The patent combines power transmission and data transmission into a single integrated cable system. The voltage converter outputs both DC voltage and data signals through the same cable interface, eliminating the need for separate power cables and data cables, thereby simplifying installation while maintaining reliable power and data transmission
Solution Approach 2:
The single cable serves multiple functions simultaneously - it transmits both electrical power (DC voltage) and data signals between the voltage converter and the electrical appliance. This multi-functional cable replaces what would traditionally require two separate cables, reducing installation complexity
