Solution Overview
Problem
Existing mounting arrangements for sensor elements on vehicle windshields occupy significant structural space, impairing the view of other traffic participants and increasing the risk of accidents.
Innovation Solution
A circular-segment-shaped mounting arrangement with a main support and receptacle, allowing for adhesive bonding to the windshield, simplified installation, and reduced space usage, along with features like a deformable installation edge and lens shade for protection and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a conventional ring-shaped frame mounting arrangement is used, then the sensor element can be securely fastened to the windshield, but the structural space occupied is large, impairing the view of other traffic participants
Solution Approach 1:
The mounting arrangement is divided into a main support structure and a separate receptacle that can be attached afterward. This segmentation allows the sensor element to be installed in a compact circular-segment-shaped receptacle rather than requiring a large ring-shaped frame, thereby reducing the occupied area while maintaining secure fastening capability
Solution Approach 2:
The receptacle is designed with a circular-segment-shaped configuration that conforms to the curved surface of the windshield. This curved geometry allows the sensor element to be mounted in a compact space while maintaining stability and proper orientation, reducing the linear dimensions needed compared to conventional flat or ring-shaped mounts
2Ease of manufacture
If the sensor element is introduced before the main support is attached to the windshield, then the installation process is simpler, but the sensor element is more vulnerable to mechanical damage
Solution Approach 1:
The receptacle is pre-formed with a protective deformable coating on its installation edge before the sensor element is introduced. This preliminary protective measure allows the sensor element to be safely pushed into the receptacle even after the main support is attached to the windshield, as the deformable coating cushions the sensor during insertion and prevents mechanical damage
3Strength
If the installation edge is rigid, then the structural strength is higher, but the sensor element surface may be damaged during insertion
Solution Approach 1:
The installation edge of the receptacle is provided with a deformable coating that is localized only at the contact point where the sensor element is inserted. This local modification provides cushioning and protection for the sensor surface during insertion, while the rest of the receptacle structure maintains its rigid strength for secure mounting
Solution Approach 2:
The deformable coating is applied in advance to the installation edge of the receptacle before the sensor element is introduced. This beforehand cushioning creates a protective barrier that absorbs mechanical shocks and prevents damage to the sensor element surface during the insertion process, while maintaining the overall structural integrity

AI summary
A mounting arrangement for fastening a sensor element to a windscreen of a motor vehicle includes a main support, which has a receptacle for the sensor element. The sensor element has a cross-section in the shape of a segment of a circle. The receptacle of the main support has a clear receptacle opening which is likewise in the shape of a segment of a circle and the dimensions of which match the sensor element.
