Dual-Part Vehicle Bumper Camera Holder
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing camera mounting solutions for vehicle bumpers fail to meet regulatory requirements, particularly in the event of impact, as they do not provide reliable and stable mounting while ensuring the camera remains undamaged and functional.
Innovation Solution
A holder with an outer and inner part, made of different materials, is designed to securely mount a camera in a through-opening of the bumper, using latch elements and screw fastening to ensure stability and protection, allowing the camera to extend through the opening and withstand impact tests.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the backup camera is positioned in front of a bumper support in the region of direct impact, then the camera can be mounted in a compact space, but the camera will be damaged during pendulum or wall collision impact tests
Solution Approach 1:
The holder is divided into two separate parts: an outer part that mounts on the exterior of the bumper and an inner part that mounts on the interior. This segmentation allows the camera to be positioned in a receiving space between the two parts, away from direct impact zones, while maintaining secure mounting through coordinated attachment of both parts to the bumper.
Solution Approach 2:
The camera is nested within the receiving space formed by the outer and inner parts of the holder. The outer part encompasses the camera from the exterior side, while the inner part provides support from the interior side, creating a protective nested structure that shields the camera during impact tests.
2Reliability
If the backup camera is positioned above the bumper support, then the camera may be protected from direct impact, but the mounting becomes less stable and the field of view is compromised
Solution Approach 1:
The holder design provides different functional qualities at different locations: the outer part provides impact protection and exterior mounting, while the inner part provides interior support and positioning. This local differentiation allows the camera to be optimally positioned for both protection and field of view requirements.
Solution Approach 2:
The dual-part holder structure serves multiple functions simultaneously: it provides impact protection, ensures stable mounting on the bumper, enables proper camera positioning for optimal field of view, and maintains a compact overall structure. The coordinated action of both parts achieves what a single-part design cannot.
3Device complexity
If a single-part holder is used to mount the camera, then the structure is simpler, but the mounting is not reliable enough to meet legal requirements for impact protection
Solution Approach 1:
The holder is segmented into an outer part and an inner part that work together to provide reliable impact protection. The outer part mounts on the exterior of the bumper and provides the primary protective structure, while the inner part mounts on the interior and secures the camera in place, creating a more reliable mounting system than a single-part design.

AI summary
A holder (10) for mounting a camera in a through-opening (12) in the region of a bumper (14) of a vehicle (16) has an outer part (18) that can be mounted on the bumper (14) from an outer face (20) of the bumper and an inner part (22) that can be mounted from an inner face (24) of the bumper (14). A receiving space (26) for receiving the camera is formed between the outer part (18) and the inner part (22) and the outer part (18) is designed for mounting the camera.
