Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a physical system is used to measure the electrical consumption of the communicating object, then the measurement precision is improved, but the use of energy by the moving object increases
Solution Approach 1:
The patent applies partial measurement by only measuring energy consumption when functionality activation is detected, rather than continuous measurement. The control unit checks for functionality activation and only initiates measurement in that case, reducing overall energy consumption while maintaining evaluation precision when needed.
Solution Approach 2:
The patent changes the operational parameters of the measurement system by dynamically switching between measurement and non-measurement states based on functionality activation detection. This parameter change allows the system to achieve precise measurements when required while minimizing energy consumption during normal operation.
2Use of energy by moving object
If software systems are used to evaluate the quantity of remaining energy, then the use of energy is reduced, but the measurement precision deteriorates
Solution Approach 1:
The patent introduces a control unit as an intermediary that bridges software detection and physical measurement. The control unit detects functionality activation and triggers physical measurement only when needed, combining the low energy consumption of software with the high precision of physical measurement in a hybrid approach.
3Measurement precision
If continuous measurement of electrical consumption is performed, then the measurement precision is improved, but the duration of action of the moving object decreases
Solution Approach 1:
The patent implements periodic measurement triggered by functionality activation events rather than continuous measurement. The control unit periodically checks for functionality activation and initiates measurement only at these intervals, extending battery service life while maintaining evaluation precision when functionalities are activated.
