Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional switches, reed contacts, light barriers or pressure sensors are used to monitor component conditions, then the monitoring function is achieved, but the device complexity and installation complexity increase
Solution Approach 1:
The patent integrates multiple sensor functions (acceleration sensing, rotational rate sensing, and determination unit) into a single actuating device. The actuating device combines the acceleration sensor, gyroscope, and determination unit into one integrated unit, eliminating the need for separate monitoring devices and reducing overall system complexity while maintaining comprehensive monitoring capabilities.
Solution Approach 2:
The actuating device is designed to perform multiple functions: it actuates the closing mechanism while simultaneously monitoring component conditions through integrated sensors. The determination unit processes data from both acceleration and rotational rate sensors to determine various states (open, closed, tilted, horizontal) and opening angles, making the device universal in its functionality.
2Measurement precision
If multiple separate sensors are installed to detect position and opening angle, then measurement accuracy is achieved, but the ease of manufacture and installation deteriorates
Solution Approach 1:
The patent combines multiple sensing capabilities (acceleration sensing for position detection and rotational rate sensing for opening angle detection) into a single integrated actuating device. This merger maintains high measurement precision for both position and opening angle while significantly simplifying installation, as only one device needs to be installed rather than multiple separate sensors.
Solution Approach 2:
The determination unit within the actuating device automatically processes sensor data to determine component states and opening angles without requiring external processing equipment. The device performs self-determination of various states (open, closed, tilted, horizontal) and calculates opening angles internally, eliminating the need for additional external units and simplifying both manufacture and installation.
3Reliability
If sensors continuously monitor all states, then detection reliability is improved, but energy consumption increases
Solution Approach 1:
The determination unit dynamically adjusts its monitoring and processing activities based on detected states. It uses acceleration sensor data to determine component states and only activates full monitoring and wireless transmission when state changes occur or when opening angle measurement is required, rather than continuously operating at full capacity. This dynamic operation maintains detection reliability while reducing overall energy consumption.
Solution Approach 2:
The device employs periodic wireless transmission of determined states and opening angles to external units rather than continuous transmission. The determination unit processes sensor data and transmits results periodically when relevant state changes occur, maintaining reliable detection capability while minimizing energy consumption from the wireless communication function.
