Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a primary-side electric power line is branched into multiple secondary-side electric power lines for vehicle charging, then the ability to supply power to multiple targets is improved, but the capability for remote monitoring and efficient control deteriorates
Solution Approach 1:
The patent divides the monitoring and control functions into separate modules: secondary-side measurement means for each branched line, primary-side measurement means for the main line, and a management apparatus that centrally processes data. This segmentation enables scalable monitoring of multiple targets while maintaining centralized control capability.
Solution Approach 2:
The management apparatus acts as an intermediary between the branched power lines and the control system. It receives measurement data from all secondary-side lines and primary-side lines, processes this information, and generates appropriate control commands, thereby enabling remote monitoring and control without requiring direct connection to each individual line.
2Adaptability or versatility
If multiple secondary-side energy supply paths are created from a single primary-side path, then energy distribution flexibility is improved, but the complexity of monitoring and controlling each path increases
Solution Approach 1:
The management apparatus performs multiple functions: it collects measurement data from all secondary-side lines, monitors primary-side power availability, makes control decisions based on power supply status, and sends control commands to opening/closing means. This multi-functional design reduces the need for separate specialized devices for each function, thereby managing complexity while maintaining distribution flexibility.
Solution Approach 2:
The system implements feedback loops where measurement data from secondary-side lines and primary-side lines continuously flows to the management apparatus, which then adjusts control commands based on the current power supply status. This feedback mechanism enables automatic adaptation to changing conditions without requiring complex manual intervention for each path.
3Productivity
If remote monitoring and control of energy supply is implemented across multiple branched paths, then energy supply efficiency is improved, but the risk of power supply cutoff due to threshold exceeding increases
Solution Approach 1:
The management apparatus monitors the primary-side power supply status in real-time and takes preliminary actions by controlling the opening/closing means of secondary-side lines before the power threshold is exceeded. When the primary-side power supply status indicates approaching threshold limits, the system proactively adjusts or stops power supply to secondary lines, preventing power cutoffs while maintaining efficient energy utilization.

AI summary
In case of branching a primary-side energy supply path into a plurality of secondary-side energy supply paths to supply energy to a plurality of supply targets, the energy supply to the plurality of supply targets is remotely monitored and efficiently controlled. A branch apparatus branches the primary-side energy supply path into the plurality of secondary-side energy supply paths. The branch apparatus is provided with secondary-side measurement means for measuring an energy supply status in each of the plurality of secondary-side energy supply paths, opening/closing means for opening and closing each of the plurality of secondary-side energy supply paths, and control means for transmitting information of measurement results of the secondary-side measurement means to a management apparatus and controlling the opening/closing means to individually open and close each of the plurality of secondary-side energy supply paths based on the control information received from the management apparatus.
