Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional vibration sensors are used without self-contained batteries and wireless communication, then device complexity is reduced, but ease of operation and productivity deteriorate due to requiring external sensors and manual mounting
Solution Approach 1:
The patent combines the vibration sensor, battery, wireless communication module, and processing unit into a single integrated vibration analyzer device. This merging eliminates the need for separate external sensors and manual connections, allowing the device to be simply mounted on the vehicle component and automatically collect and transmit vibration data wirelessly, thereby improving ease of operation without significantly increasing perceived complexity.
Solution Approach 2:
The vibration analyzer is designed as a self-contained unit with an integrated battery that provides autonomous power supply, eliminating the need for external power sources or frequent manual intervention. The device independently performs vibration detection, data processing, and wireless transmission, requiring minimal user involvement after initial deployment, thus enhancing ease of operation.
2Measurement precision
If conventional single-axis vibration sensors are used, then device complexity is reduced, but measurement precision deteriorates due to limited vibration detection capability
Solution Approach 1:
The patent employs a 3-axis accelerometer that measures vibration along three perpendicular axes (X, Y, Z) simultaneously. This dimensional expansion from single-axis to three-axis measurement enables comprehensive capture of torsional and multi-directional vibrations, significantly improving measurement precision by detecting vibration components that would be missed by single-axis sensors.
Solution Approach 2:
The multi-axis accelerometer serves multiple functions: it detects vibrations in different directions, identifies torsional vibration patterns, and provides comprehensive vibration characterization. This universal sensing capability improves measurement precision across various vibration types without requiring multiple separate single-axis sensors, thereby managing device complexity effectively.
3Adaptability or versatility
If vibration sensors are mounted on the plane of measured vibration axis only, then ease of operation is improved, but adaptability deteriorates due to limited mounting flexibility
Solution Approach 1:
The 3-axis accelerometer measures vibrations along three perpendicular axes, which means the sensor can detect vibration regardless of its mounting orientation. This dimensional measurement capability allows the device to be mounted on various surfaces and components at different angles, significantly improving adaptability and mounting flexibility without compromising measurement accuracy.
Solution Approach 2:
The vibration analyzer is designed to function effectively regardless of mounting orientation, making it universally applicable to different vehicle components and locations. The device can be mounted on engines, exhaust systems, or other vibrating components with varying surface geometries, enhancing adaptability while maintaining ease of deployment through simple attachment procedures.
4Productivity
If external sensors and multi-channel analyzers are used without network capabilities, then device complexity is reduced, but productivity deteriorates due to inefficient data collection and analysis
Solution Approach 1:
The patent replaces manual data collection and analysis procedures with an automated electronic system. The vibration analyzer continuously monitors vibration parameters, processes the data internally, and wirelessly transmits results to remote devices or cloud platforms. This substitution of manual operations with automated electronic processing significantly improves data collection efficiency and productivity.
Solution Approach 2:
The wireless communication module acts as an intermediary between the vibration sensor and external analysis systems. It enables automatic data transmission from the vehicle-mounted sensor to remote devices, eliminating the need for manual data retrieval and initial analysis steps, thereby improving productivity through automated data flow.
