Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If level measuring devices are powered via cables, then reliable power supply and data transmission are ensured, but wiring effort is considerable and application range is limited
Solution Approach 1:
The patent extracts the power supply and data transmission functions from cable connections by implementing a battery-powered autonomous measuring device. The device includes a battery (102) for power supply and a radio module (106) for wireless data transmission, eliminating the need for physical cable connections while maintaining reliable operation.
Solution Approach 2:
The patent introduces a radio module (106) as an intermediary for wireless communication between the measuring device and external systems. This radio interface enables data transmission without physical cable connections, resolving the contradiction between reliability and ease of installation.
2Ease of operation
If battery-operated mode is used, then wiring effort is reduced and application range is expanded, but battery life is limited and requires monitoring
Solution Approach 1:
The patent implements preliminary monitoring of battery status through a remaining service life determination unit (109) that continuously tracks battery charge level and calculates expected remaining operational time. This allows proactive management of battery life before depletion occurs, enabling planned maintenance intervals and preventing unexpected device failure.
Solution Approach 2:
The patent establishes a feedback loop where the remaining service life determination unit (109) continuously monitors battery status and provides information about remaining operational time. This feedback enables adaptive adjustment of measurement intervals and transmission frequency to optimize battery consumption while maintaining required functionality.
3Measurement precision
If frequent measurements and transmissions are performed, then measurement accuracy and data availability are improved, but energy consumption increases
Solution Approach 1:
The patent implements dynamic adjustment of measurement and transmission parameters based on battery status. The remaining service life determination unit (109) adapts the measurement sequence and radio transmission frequency according to available battery capacity, allowing high measurement frequency when battery charge is充足 and reducing frequency when battery level decreases, thus optimizing the balance between measurement precision and energy consumption.
