Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a physical system is used to measure the electrical consumption of the connected device, then the measurement precision is improved, but the use of energy by the moving object increases
Solution Approach 1:
The patent creates a software model (copy) of the electrical consumption behavior of different device components. Instead of using physical measurement systems, the software system replicates consumption patterns through pre-configured data structures that mirror actual energy usage, thereby achieving measurement without additional physical energy expenditure.
Solution Approach 2:
The patent replaces the physical measurement system with a software-based evaluation system. The mechanical/physical act of measuring electrical consumption is substituted by computational processes that calculate and estimate energy usage based on software-defined parameters and algorithms, eliminating the need for physical measurement hardware.
2Use of energy by moving object
If a software-based system is used to assess the amount of remaining battery energy, then the use of energy is reduced, but the measurement precision deteriorates
Solution Approach 1:
The patent performs preliminary action by pre-configuring consumption data for various device components before runtime. The software system prepares evaluation criteria, consumption profiles, and calculation parameters in advance, allowing accurate real-time assessment without requiring energy-intensive measurement operations during actual battery monitoring.
Solution Approach 2:
The software system serves itself by using the device's existing operational data and built-in components to evaluate its own battery status. The system leverages information already available within the device (component usage patterns, operational states) to self-assess energy consumption without external measurement tools, maintaining precision while minimizing additional energy use.

AI summary
The present invention relates to a method and a device for evaluating the amount of electrical energy consumed by a battery-powered communicating object, the communicating object being capable of performing a plurality of functionalities, according to the invention: - an activation of a function of the communicating object is detected (E30), - a table is checked (E31) to see if an electrical energy consumption is associated with the activated function, - an estimate of the amount of electrical energy consumed by the activated function is ordered (E32) if an electrical energy consumption is associated with the activated function, - a measurement of the amount of electrical energy consumed by the activated function is ordered (E35) if an electrical energy consumption is not associated with the activated function.
