Solution Overview
Problem
Existing rotation detection devices for vehicle pedals lack protection from impacts and dust, and are not robust enough to maintain the integrity of the moving parts during assembly, handling, transport, and storage.
Innovation Solution
A rotation detection device with a cover that protects the movable part from impacts and dust, and guides and retains it within a housing, ensuring axial and radial alignment, thereby enhancing the device's compactness and robustness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the movable first part is left exposed without a cover, then the device structure remains simple and compact, but the first part is vulnerable to impacts and dust during assembly, handling, transport, and storage
Solution Approach 1:
A cover is introduced to protect the movable first part from impacts and dust during assembly, handling, transport, and storage. The cover acts as a protective shell that can be coupled to the stationary second part, enclosing the vulnerable movable components while allowing the device to remain relatively compact.
2Manufacturing precision
If guide grooves are added to the cover for guiding the first part, then the alignment precision between first and second parts is improved, but the manufacturing complexity of the cover increases
Solution Approach 1:
The cover incorporates guide grooves that cooperate with guide protrusions on the movable first part. These grooves provide mechanical guidance during assembly, ensuring proper alignment between the movable and stationary parts. The grooves are integrated into the cover structure, providing guidance functionality without requiring separate guiding components.
3Stability of the object's composition
If the cover is designed to retain the first part in the housing, then the stability of the device during handling and transport is improved, but the device complexity increases
Solution Approach 1:
The cover serves multiple functions: it protects the movable first part from impacts, provides dust protection, guides the first part during assembly through integrated guide grooves, and retains the first part within the housing of the stationary second part. This multi-functional design improves stability during handling and transport while minimizing the increase in device complexity by combining multiple functions into a single component.

Function Achieved in This Case
The solution provides a more compact and robust rotation detection device that effectively protects the moving parts from damage and maintains their alignment, ensuring reliable operation and ease of assembly, handling, and storage.
Implementation Method 1
a magnetic field sensing component arranged in the first or in the second part and a magnetic element arranged in that part of the first or the second part that does not comprise the magnetic field sensing component. The magnetic field sensing component generates an electric signal originated from the magnetic interaction between the first and the second part when the first and the second part are moving in relation to each other.
