Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Precise positioning and assembly of vision sensors on a vehicle's roof is challenging, impacting ergonomics in the assembly line, and accessing sensors for service events is cumbersome.
Innovation Solution
A sensor mounting assembly comprising a cover coupled to the glass roof and a bracket secured to the roof rail from the interior cabin, allowing for precise sensor positioning and assembly without climbing onto the roof, with the bracket being removable for easy service access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If vision sensors are positioned on the roof of the vehicle to facilitate optimal field-of-view, then the sensing capability is improved, but the difficulty of positioning and assembly increases
Solution Approach 1:
The sensor mounting system is divided into separate modular components: a sensor holder that attaches to the roof rail and a sensor assembly that can be independently positioned. This segmentation allows the sensor to be precisely positioned on the holder while the holder itself is easily attached to the roof rail, resolving the contradiction between precise positioning and ease of assembly.
Solution Approach 2:
A sensor holder acts as an intermediary component between the roof rail and the vision sensor. The holder provides a standardized mounting interface that simplifies assembly while enabling precise positioning of the sensor relative to the vehicle body, thus facilitating both optimal field-of-view and ease of manufacture.
2Measurement precision
If the sensor is mounted on the roof to achieve optimal field-of-view, then the sensing performance is improved, but the ergonomics in the assembly line deteriorates
Solution Approach 1:
Instead of mounting the sensor directly from above the roof, the mounting structure is inverted to be accessible from the interior cabin. The sensor holder attaches to the roof rail from below, allowing assembly workers to perform positioning and assembly operations from a comfortable standing position inside the vehicle rather than climbing onto the roof.
Solution Approach 2:
The sensor holder serves as an intermediary that enables access to the sensor mounting location from the interior cabin. By attaching the holder to the roof rail from below and extending it upward, the system allows workers to assemble sensors from a ergonomically favorable position while still achieving optimal sensor placement on the roof.
3Reliability
If the sensor is securely mounted on the roof for stable operation, then the reliability is improved, but the ease of service and repair deteriorates
Solution Approach 1:
The mounting system incorporates dynamic characteristics that allow it to be rigid during normal operation for stable sensor performance, but becomes easily detachable when service is required. The sensor holder can be quickly removed from the roof rail and reattached, enabling rapid sensor replacement while maintaining reliable mounting during vehicle operation.
Solution Approach 2:
The sensor mounting system is segmented into detachable components: the sensor holder that attaches to the roof rail and the sensor assembly. This segmentation allows the sensor to be easily removed and replaced by simply detaching it from the holder, while the holder remains securely mounted to the roof rail, thus maintaining both reliable operation and ease of service.

AI summary
A sensor mounting assembly is provided. The sensor mounting assembly includes a cover coupled to a glass roof of a vehicle. The cover encloses a sensor that is disposed proximate to the glass roof of the vehicle. The sensor mounting assembly further includes a bracket coupled to a roof rail that may be located beneath the glass roof of the vehicle. The bracket is secured to the roof rail from an interior cabin of the vehicle, to hold the sensor proximate to the glass roof of the vehicle.
