Rectangular Sensor Fastening Base Plate with Integrated Guide Walls
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for attaching sensors to carrier parts are either overly complex or excessively costly, particularly when dealing with large sensors, as seen in devices for rectangular and circular sensors.
Innovation Solution
A device featuring long guide walls and shorter stop parts, made of sheet metal with a rectangular base plate and hot-melt adhesive, ensures stable and precise fixation of rectangular sensors with minimal material usage, incorporating angled guide sections and centering portions to prevent misalignment and twisting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a device with bracket parts and pins is used to attach a rectangular sensor to a carrier part, then the sensor can be securely fastened, but the device structure becomes relatively complicated
Solution Approach 1:
The patent extracts and eliminates the complex bracket parts and pin mechanisms from the fastening system. Instead, it uses a simplified base plate with integrated guide walls and stop parts that directly guide and secure the sensor in place, removing unnecessary intermediate components while maintaining secure attachment
Solution Approach 2:
Rather than using protruding pins and brackets to hold the sensor, the invention inverts the approach by using recessed guide walls and stop parts formed directly in the base plate to create the positioning and fastening function, simplifying the overall structure
2Reliability
If a device with guide wall and latching lugs is used to attach a large circular sensor to a carrier part, then the sensor can be secured, but the material expenditure becomes relatively high and costly
Solution Approach 1:
The patent segments the fastening function into distinct elements: guide walls for positioning, stop parts for limiting movement, and nose sections for engagement. This segmentation allows each element to be optimized for minimal material usage while performing its specific function efficiently
Solution Approach 2:
The invention applies local quality by making the guide walls long and continuous for stable positioning, while the stop parts are shorter and only where needed for engagement. This localized approach to material distribution ensures stability where required while minimizing material expenditure overall

AI summary
A device for fastening a rectangular sensor to a support part has a base plate (2) in which a receiving recess (3) is made. Guide walls (6, 7) are integrally formed on mutually opposite edge sides (4, 5) of the receiving recess (3), said guide walls extending between two corner regions (18, 20; 19, 21) of the receiving recess (3), which corner regions end an edge side (4, 5). Furthermore, stop parts (10, 11) which are shorter than the length of the guide walls (6, 7) are integrally formed on the other edge sides (8, 9), in each case in the central region thereof, the stop parts each having at least one stop section (26) oriented at right angles to the base plate (2), wherein the guide sections (22) and the stop sections (26) bear against a wall of the sensor when the sensor is fitted. As a result, even sensors of relatively large dimensions can be fastened to the support part in a stable and accurately fitting manner with relatively little expenditure on material.
