Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple electricity consumption meters are installed to monitor individual branch consumptions, then measurement precision is improved, but device complexity and cost increase
Solution Approach 1:
The patent uses a simplified current detection model that copies the measurement function from traditional meters but implements it through software algorithms analyzing voltage and current waveforms instead of hardware meters. This allows individual branch consumption to be determined without installing physical metering devices in each branch.
Solution Approach 2:
The upstream measurement device performs multiple functions: it measures overall consumption, detects individual branch consumption through waveform analysis, and provides monitoring capabilities. This single device replaces what would traditionally require multiple specialized meters, reducing system complexity while maintaining measurement precision.
2Measurement precision
If multiple electricity consumption meters are installed to monitor individual branch consumptions, then measurement precision is improved, but cost increases
Solution Approach 1:
The patent replaces expensive traditional electricity meters with inexpensive current detectors and sensors that can be implemented as simple electronic components. The measurement capability is achieved through software processing rather than expensive hardware, dramatically reducing the cost of the monitoring system while maintaining adequate measurement precision.
Solution Approach 2:
Instead of using expensive dedicated metering hardware in each branch, the system uses a centralized upstream measurement device that copies the measurement function through software algorithms. This approach achieves individual branch measurement capability at a fraction of the cost of installing multiple traditional meters.
3Measurement precision
If multiple electricity consumption meters are installed to monitor individual branch consumptions, then measurement precision is improved, but space requirements increase
Solution Approach 1:
The patent extracts the measurement function from individual branch locations and consolidates it at the upstream position. By taking out the metering function from each branch and implementing it centrally through waveform analysis, the system eliminates the need for physical space in multiple branch panels while maintaining individual consumption measurement capability.
Solution Approach 2:
The upstream measurement device serves multiple purposes: measuring overall consumption, determining individual branch consumption through algorithmic analysis, and providing monitoring functions. This multi-functionality consolidates what would traditionally require multiple separate devices occupying space in various panels into a single upstream device.

AI summary
In order to determine a consumption in a group of branches (4) of individual distribution of electrical energy, a method comprises steps wherein: a) a change in electrical consumption is detected in the branches (4), and b) information relating to an electric current (l2, I3, U) is read in a specific branch (4), then c) using said information, an indication is established according to which said change took place in the specific branch (4), then d) using measurements taken of the overall power supply (I, U) of the group of branches (4) before the change and measurements taken of said overall power supply (I, U) after the change, in addition to said indication, an individual energy consumption of said specific branch (4) is determined.
