Transducer Magnet Assembly with Coupling Ring for Shifting Rail
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional path sensor arrangements face challenges in securely coupling transducer elements to shifting rails, leading to issues with air-gap tolerance and increased assembly complexity and cost.
Innovation Solution
A transducer magnet assembly featuring a coupling ring and magnet support, where the coupling ring encloses the shifting rail, and the magnet support locks the ring via a snap-on connection, with optional spring elements for tolerance compensation, allowing for simplified assembly and reduced air-gap problems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a sensor and transducer element are mounted separately on different components, then the assembly structure is simple, but the air-gap tolerance between sensor element and transducer element increases
Solution Approach 1:
The patent combines the sensor element and transducer element into a single integrated assembly unit. The sensor element is mounted on a sensor carrier that is rigidly connected to the transducer element, ensuring fixed relative positioning. This merging eliminates air-gap tolerance issues while maintaining assembly simplicity through the unified structure.
2Reliability
If a complex fastening device with spring elements and holding elements is used to fix the transducer element, then the coupling security is improved, but the assembly effort and cost increase
Solution Approach 1:
The sensor carrier and transducer element are merged into a single rigid assembly unit that moves together as one piece. This integration provides inherent coupling security without requiring additional complex fastening devices, spring elements, or holding elements, thereby reducing assembly effort and cost.
Solution Approach 2:
The sensor carrier serves multiple functions simultaneously: it mounts the sensor element, rigidly connects to the transducer element, provides structural support, and ensures proper positioning. This multi-functionality eliminates the need for separate fastening components while maintaining coupling security.
3Reliability
If the sensor carriage is securely connected to the sensor housing as an inseparable assembly, then the assembly reliability is improved, but the device complexity increases
Solution Approach 1:
The sensor element and transducer element are merged into a single inseparable assembly unit through rigid connection. This ensures they always move together with fixed relative positioning, improving assembly reliability. The simplicity of the rigid connection structure avoids increasing device complexity.
