Engineering Contradiction Analysis
1Volume of moving object
If the telemetry device is integrated directly into the bearing element body, then the system compactness and integration are improved, but the device complexity and interference from rotating components increase
Solution Approach 1:
The bearing element is divided into functional segments: the bearing element body, the telemetry device, and a connecting element. This segmentation allows each component to be optimized independently while maintaining overall integration, reducing the complexity of integrating all functions into a single monolithic structure.
Solution Approach 2:
A connecting element is introduced as an intermediary between the bearing element body and the telemetry device. This mediator facilitates the connection while allowing for material optimization and reducing direct interference between the rotating bearing components and the telemetry device, thus managing device complexity.
2Measurement precision
If the telemetry device is positioned closer to the sensor, then the measurement accuracy is improved, but the interference from rotating components increases
Solution Approach 1:
The connecting element serves as an intermediary that positions the telemetry device in optimal proximity to the sensor for accurate measurement, while simultaneously acting as a shield or barrier that reduces interference from rotating components such as the shaft.
Solution Approach 2:
The telemetry device is extracted from the immediate rotating zone and positioned on the bearing element body, separated by the connecting element. This extraction removes the sensitive telemetry components from the harmful electromagnetic or mechanical interference zone while maintaining measurement capability.
3Ease of operation
If the bearing element requires minimal user-side adaptations, then the ease of installation is improved, but the manufacturing complexity increases
Solution Approach 1:
The bearing element body, sensor, telemetry device, and connecting element are merged into a pre-assembled integrated unit. This combination shifts manufacturing complexity to the production phase where standardized components can be efficiently assembled, while delivering ease of installation during deployment since the system requires minimal user-side adaptations.
Solution Approach 2:
The sensor and telemetry device are preliminarily assembled and tested on the bearing element body before delivery. This preliminary action ensures that the system is ready for installation with minimal user-side work, as the complex integration and testing have already been performed during manufacturing.
