Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sensor mounting solutions for machinery, such as motors, face challenges due to vibrations and resonance issues, particularly when sensors are mounted on cooling ribs with varying dimensions and spacings, leading to inaccurate measurements and displacement.
Innovation Solution
A mounting device with a base element featuring multiple clamp elements that securely attach to machinery bodies, including motors, using form-fitting or force-fitting connections to minimize resonance and ensure accurate vibration measurement transmission.

Engineering Contradiction Analysis
1Reliability
If a sensor is mounted directly on cooling ribs of a motor, then the sensor can be positioned close to the machinery body for monitoring, but the sensor may be displaced due to strong vibrations and resonances may occur
Solution Approach 1:
The mounting device is segmented into a base element and multiple clamp elements (at least three) that can independently engage with different ribs. This segmentation allows the mounting device to distribute attachment points across multiple ribs, reducing the impact of vibrations on any single connection point and preventing sensor displacement.
Solution Approach 2:
The mounting device is pre-configured with multiple clamp elements positioned to engage with multiple ribs before the sensor is installed. This preliminary arrangement ensures that the sensor is securely anchored to the machinery body through multiple attachment points, preventing displacement during operation and reducing resonance effects.
2Ease of manufacture
If a mounting solution is designed for specific motor types with fixed rib dimensions, then the mounting can be simple, but the solution lacks universal applicability to different motor types
Solution Approach 1:
The mounting device is designed as a universal solution that can be applied to different motor types with varying rib configurations. The base element incorporates multiple clamp elements that can engage with ribs of different dimensions and spacings, allowing the same mounting device to be used across various motor types without requiring custom designs for each application.
Solution Approach 2:
The clamp elements are designed to be adjustable or flexible in their positioning, allowing them to adapt to different rib configurations dynamically. This enables the mounting device to maintain secure attachment across various motor types while keeping the overall design simple and manufacturable.
3Ease of operation
If a sensor is mounted with a loose connection to the motor, then installation is easy, but resonances may occur and measurements become inaccurate
Solution Approach 1:
The mounting device segments the connection between sensor and motor body into multiple discrete clamp elements distributed across at least three ribs. This segmentation provides secure attachment that eliminates loose connections and resonances, while the modular design keeps installation straightforward through simple attachment mechanisms at each clamp point.
