Pivotable Radar Sensor Mounting Device for Vehicle Spare Wheel Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing emergency braking assistance systems for motor vehicles face challenges in mounting radar sensor devices centrally on the front due to obstructions, such as spare wheels, which hinders optimal operation.
Innovation Solution
A foldable holding device is designed to attach to the motor vehicle, allowing the radar sensor device to be positioned adjacent to the spare wheel's exit opening, with a pivotable and adjustable mechanism that ensures secure mounting and easy access for spare wheel removal, utilizing screw connections and latching elements for precise positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the radar sensor device is mounted centrally on the front of the motor vehicle, then the sensor operation is optimal, but the spare wheel cannot be removed due to obstruction by the holding device
Solution Approach 1:
The holding device for the radar sensor device is designed to be pivotable about a pivot axis, allowing it to change position between blocking and non-blocking the exit opening. This dynamic positioning enables the holding device to maintain central sensor mounting while periodically clearing the path for spare wheel removal.
Solution Approach 2:
The holding device is divided into a support section mounted on the motor vehicle and a pivotable holding section that can be positioned independently. This segmentation allows the sensor mounting function to be separated from the spare wheel access path, resolving the spatial conflict between central mounting and wheel removal.
2Manufacturing precision
If the holding device blocks the exit opening to secure the sensor position, then the sensor remains correctly positioned, but the spare wheel cannot be removed
Solution Approach 1:
The holding device incorporates a pivotable mechanism that allows temporary repositioning during spare wheel removal operations. The device can be rotated out of the way to clear the exit opening, then returned to its blocking position to maintain precise sensor alignment during normal operation.
Solution Approach 2:
Before removing the spare wheel, the holding device is preliminarily repositioned to clear the exit opening. This preliminary action prevents obstruction during the wheel removal process while maintaining precise sensor positioning during normal vehicle operation.
3Adaptability or versatility
If the holding device is made adjustable to accommodate both sensor mounting and spare wheel removal, then both functions can be performed, but the device complexity increases
Solution Approach 1:
The holding device uses a relatively simple pivotable mechanism with a pivot axis and connecting elements to achieve dual functionality. The pivotable design provides the necessary adaptability for both sensor mounting and spare wheel removal without requiring complex adjustable mechanisms.
Solution Approach 2:
The holding device is designed as a multi-functional component that serves both to mount the radar sensor device centrally and to allow spare wheel removal. The pivotable mechanism enables a single device structure to perform multiple functions that would otherwise require separate systems.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables the central mounting of radar sensor devices while allowing convenient removal of spare wheels, ensuring the sensor's optimal operation and positioning without the need for re-adjustment, ensuring the sensor remains correctly positioned even if connections are unintentionally released.
Implementation Method 1
The snap or detent element preferably comprises a biasing element, for example a spring, by means of which it can be automatically brought into the fixed state.

AI summary
The invention relates to a holding device (1) for attachment to a motor vehicle, preferably to the front of the vehicle (B). The holding device (1) comprises a support section (2), preferably two longitudinal members, for mounting to the motor vehicle and a holding section (3) for holding a functional element (S), in particular a sensor device, and for positioning it adjacent to an outlet opening (A) for a fastening device (10) for a spare wheel (R) for the motor vehicle. The holding section (3) is pivotable about a pivot axis (4) from a first state in which it at least partially closes the outlet opening (A) to a second state in which it releases the outlet opening (A) so that the spare wheel (R) can be removed.
