Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle seat tracks with position sensors are bulky, costly, and prone to damage or interference from external elements, compromising safety and ease of manufacturing.
Innovation Solution
A vehicle seat track design featuring a female rail surrounding a male rail with a position sensor housed within a case that is partially or fully integrated into the male rail, allowing for reduced dimensions and simplified assembly, while ensuring the sensor is protected from external interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the position sensor is exposed externally in conventional track designs, then the sensor can detect position, but the track becomes bulky, costly, and vulnerable to damage from external elements
Solution Approach 1:
The position sensor is nested within the case that is integrated into the male rail structure. The case acts as a protective housing that contains the sensor while utilizing the existing rail volume, thereby protecting the sensor from external damage without significantly increasing the overall track dimensions.
Solution Approach 2:
The case housing the position sensor is merged with the male rail structure, forming an integrated assembly. This combination eliminates the need for separate external sensor mounting structures, reducing overall track volume while maintaining sensor protection and functionality.
2Ease of manufacture
If the position sensor is housed within an integrated case in the male rail, then the track dimensions are reduced and manufacturing is simplified, but the sensor must be protected from interference
Solution Approach 1:
The case is integrated with the male rail as a unified structure, simplifying manufacturing by reducing the number of separate components. The integrated design allows for easier assembly while the case structure inherently provides protection against external interference to the sensor.
Solution Approach 2:
The case acts as an intermediary structure between the external environment and the position sensor. It mediates by providing physical protection and isolation from harmful external factors while allowing the sensor to function properly within the protected enclosure.
3Device complexity
If conventional external sensor mounting is used, then installation is straightforward, but the track structure becomes more complex and expensive
Solution Approach 1:
The sensor housing case is merged with the male rail structure, eliminating the need for separate external mounting brackets, supports, or attachment mechanisms. This integration reduces device complexity by consolidating components and lowers manufacturing costs through reduced part count and simplified production processes.
Solution Approach 2:
The male rail structure serves multiple functions: it provides the sliding mechanism for seat adjustment and simultaneously houses the position sensor within its integrated case. This multi-functionality reduces overall device complexity by making the rail structure serve dual purposes rather than requiring separate dedicated sensor mounting structures.

AI summary
A track for a vehicle seat comprising: a female rail; a male rail, mounted sliding relative to the female rail where the female rail comes to surround the male rail with a substantially flat wall of the female rail located across from a substantially flat wall of the male rail; a position sensor for the male rail relative to the female rail, received inside a case. The case is fixed to the male rail at least partially extending into the volume of the male rail, such that the position sensor is located across from the substantially flat wall of the female rail, after having been inserted and slid through at least one opening arranged in the substantially flat wall of the male rail.
