Bearing Mounted Sensor Assembly Alignment and Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sensor mounting configurations lack a clear indication of proper alignment and are susceptible to loosening during operation, with non-uniform securing forces that can allow contaminant intrusion.
Innovation Solution
A sensor assembly with an insert and tabs that secure the sensor in a desired orientation, using an o-ring for sealing and biasing, and a cap to prevent removal, ensuring uniform securing forces and visual confirmation of proper alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a threaded fastener is used to secure the sensor assembly, then the sensor can be mounted to the fixed structure, but the securing force becomes non-uniform and the assembly is susceptible to loosening during operation
Solution Approach 1:
The mounting clip is segmented into two separate clips instead of using a single threaded fastener. Each clip independently secures the sensor assembly, distributing the securing force uniformly across the mounting interface and preventing loosening during operation.
2Manufacturing precision
If a threaded fastener is used to secure the sensor assembly, then the sensor can be mounted to the fixed structure, but there is no visual indication of proper alignment
Solution Approach 1:
The sensor assembly includes a visual indicator feature that changes color or provides visual feedback when proper alignment is achieved. This allows operators to immediately confirm correct alignment during installation without requiring additional measurement tools.
3Reliability
If a single threaded fastener is used, then the sensor assembly can be secured, but contaminant intrusion is permitted due to non-uniform securing forces
Solution Approach 1:
Using two separate mounting clips creates multiple sealing interfaces instead of a single fastener point. This distributes the sealing force uniformly, ensuring the seal remains intact and prevents contaminant intrusion while maintaining mounting reliability.
4Ease of operation
If the sensor assembly is designed for tool-free mounting, then ease of installation is improved, but secure mounting without loosening becomes more difficult to achieve
Solution Approach 1:
The mounting clips are designed with self-locking features that automatically secure the sensor assembly in place without requiring tools. The clips engage with the sensor housing and lock into position, providing secure mounting that resists loosening while maintaining tool-free installation.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution provides reliable and contamination-free sensor alignment and secure mounting, maintaining uniform biasing forces during operation and preventing improper removal.
Implementation Method 1
An o-ring is disposed between the sensor and the insert to seal the interface
Implementation Method 2
An o-ring is disposed between the sensor and the insert to seal the interface and provide a biasing force to maintain the desired position of the sensor assembly during operation

AI summary
A sensor assembly includes an insert mounted within a fixed structure and tabs that engaged the insert to secure the sensor assembly in a desired orientation. A cap is assembled over the sensor assembly and the interface between the tabs and the insert to prevent undesired removal.
