Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sensors are limited to fastening in T-shaped grooves and are prone to electrical or electronic failures due to potential insulation issues between the sensor and fastening body, affecting their electromagnetic compatibility.
Innovation Solution
A sensor with a metallic clamping body connected to a defined electrical potential, such as ground potential, which eliminates insulation between the clamping and fastening bodies, using expandable elements like threaded pins or pins to secure the sensor in various groove geometries without undercuts, ensuring reliable and stable attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If sensors are fastened in T-shaped grooves using prior art methods, then the sensor can be securely attached, but the sensor is limited to specific groove geometries and requires complex fastening devices with multiple components
Solution Approach 1:
The clamping body is designed with a universal geometry that can accommodate various groove shapes (T-shaped, U-shaped, rectangular) without requiring different fastening devices. The clamping body's expandable design allows it to adapt to different groove geometries while maintaining a consistent fastening mechanism across all applications.
Solution Approach 2:
The fastening system is divided into separate functional components: the clamping body that provides the expanding force and the groove that provides the mounting interface. This segmentation allows the clamping body to be designed independently to work with various groove geometries, increasing versatility while keeping the overall system simple.
2Reliability
If the clamping body is made of metal and connected to a defined electrical potential, then electromagnetic compatibility is improved and electrical failures are reduced, but the manufacturing process becomes more complex
Solution Approach 1:
The electrical connection function is merged into the clamping body itself by making it metallic and connecting it to a defined electrical potential. This eliminates the need for separate insulation components or additional electrical connection elements, thereby improving reliability while keeping the manufacturing process simple.
Solution Approach 2:
The clamping body is made of homogeneous metallic material that provides both mechanical clamping function and electrical connection function. This material homogeneity simplifies manufacturing compared to composite structures that would require multiple materials and joining processes.
3Strength
If an expanding threaded pin is used to actuate the clamping body, then secure fastening is achieved, but the fastening process requires threading operations which increase manufacturing complexity
Solution Approach 1:
The threaded pin mechanism replaces a complex multi-component fastening system with a simple screw-thread actuation system. The threading provides mechanical advantage to generate strong clamping forces while requiring minimal manufacturing complexity, as threading is a standard, well-established manufacturing process.
4Reliability
If the sensor housing protrudes into the fastening groove, then the sensor can be securely attached, but the sensor design becomes more complex and requires precise dimensional matching
Solution Approach 1:
The clamping body is designed to be dynamically expandable and contractible, allowing the sensor housing to protrude into the groove during operation while maintaining secure attachment. The dynamic expansion capability provides reliable fastening without requiring precise static dimensional matching between the housing and groove.
