Tailgate Warning Triangle Mounting With Integrated Trim Reinforcement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fastening devices for securing warning triangles and first-aid kits in vehicle trunks are complex to manufacture, require additional installation space, and do not prevent uncontrollable movement during accidents.
Innovation Solution
A holding device comprising a tailgate, a holding element connected to the tailgate, and a tailgate trim panel with a recess, allowing for a stable and easy-to-access mounting of the warning triangle without additional fastening elements, using a form-fitting and force-locking mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If additional fastening devices are used to secure the warning triangle, then the stability and reliability of the mounting is improved, but the device complexity and manufacturing cost increase
Solution Approach 1:
The patent integrates the fastening function directly into the tailgate trim panel by forming a recess that receives the warning triangle. The holding element is incorporated into the trim panel structure itself, merging the trim and fastening functions into a single integrated component, thereby eliminating separate fastening devices while maintaining secure mounting
Solution Approach 2:
The tailgate trim panel serves multiple functions: it provides aesthetic coverage of the tailgate base body, structural reinforcement through the holding element, and secure retention of the warning triangle via the recess. This multi-functionality eliminates the need for dedicated fastening devices while maintaining reliability
2Reliability
If additional fastening devices are used to secure the warning triangle, then the stability of the mounting is improved, but the installation space required increases
Solution Approach 1:
The fastening function is merged into the tailgate trim panel structure itself. The holding element is formed as part of the trim panel, eliminating the need for separate fastening devices that would occupy additional installation space in the trunk
3Ease of operation
If the warning triangle is easily accessible in the trunk, then the ease of operation is improved, but the stability during accidents may be compromised
Solution Approach 1:
The tailgate trim panel creates a localized recess with specific geometric features that provide secure retention of the warning triangle. The recess is positioned and dimensioned to ensure the triangle remains stable during accidents while being easily accessible during normal operation
4Ease of manufacture
If simple fastening methods are used, then the ease of manufacture is improved, but the stability and reliability of the mounting deteriorates
Solution Approach 1:
The fastening function is integrated into the tailgate trim panel structure, which is already a necessary component for aesthetic and structural purposes. This merging allows the use of standard trim panel manufacturing processes without requiring additional complex fastening device fabrication
Solution Approach 2:
The tailgate trim panel itself provides the fastening function through its recess structure. The trim panel serves itself by incorporating the holding element, eliminating the need for separate fastening devices and simplifying the overall manufacturing process while maintaining reliable mounting

AI summary
The invention relates to a holding device (40) for a warning triangle (42) in a trunk (36) of a motor vehicle (10). The holding device (40) comprises a tailgate (26), a holding element (44) connected to the tailgate (26), and a tailgate trim (46) which covers a base body (62) of the tailgate (26) on the side of the tailgate (26) facing the trunk (36). A recess (48) is formed in the tailgate trim (46), in which the warning triangle (42) is received. The holding element (44) rests against the tailgate trim (46) in the region of the recess (48) of the tailgate trim (46) or receives the tailgate trim (46) in such a way that the holding element (46) forms a stiffener (50) for the tailgate trim (46).The invention further relates to a motor vehicle (10) having such a holding device (40), wherein the holding device (40) is arranged in a trunk (36) of the motor vehicle (10).
