Tailgate Guide Bumper Integrated with Lamp Housing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tailgate guide bumpers require extensive assembly time and additional reinforcing members due to perpendicular fastening directions and suboptimal load distribution, leading to inefficiencies in preventing tailgate movement during vehicle travel.
Innovation Solution
A tailgate guide bumper system where the guide bumper member is fastened to the tailgate inner panel with a single bolt and the supporting part, integrated with the lamp housing, is positioned to align with the maximum load application point, reducing assembly time and reinforcing needs by using a rubber and steel composite guide bumper member and a plastic guide bumper supporting part.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If multiple fastening bolts are used to fasten the first member to the tailgate inner panel and the second member to the vehicle body, then sufficient rigidity is achieved, but assembly time and labor costs increase significantly
Solution Approach 1:
The patent integrates the guide bumper function directly into the lamp housing structure, merging two separate components (guide bumper and lamp housing) into one unified structure. This eliminates the need for separate fastening operations for both the guide bumper and lamp housing, significantly reducing assembly time while maintaining structural rigidity through the integrated design
Solution Approach 2:
The lamp housing is designed to serve multiple functions: it provides illumination (original function) and simultaneously acts as the guide bumper structure (additional function). This multi-functionality reduces the number of separate components and fastening operations required, addressing the time-loss issue while maintaining the necessary mechanical strength
2Stability of the object's composition
If fastening bolts are arranged in perpendicular directions to secure rigidity, then structural stability is improved, but additional reinforcing members are required increasing complexity
Solution Approach 1:
The guide bumper member is integrated into the lamp housing structure, combining the support function with the existing lamp housing. This integration eliminates the need for separate reinforcing members, as the lamp housing itself provides the necessary structural stability through its design that accommodates the guide bumper function
Solution Approach 2:
The guide bumper member uses a composite structure combining rubber and steel materials. The rubber portion provides shock absorption and flexibility, while the steel reinforcement provides structural strength and rigidity. This composite material approach achieves the required structural stability without needing additional separate reinforcing members
3Ease of manufacture
If the guide bumper is installed on the lower end of the tailgate, then installation position is simplified, but it is spaced apart from the maximum load application point reducing effectiveness
Solution Approach 1:
The patent repositions the guide bumper member from the traditional lower end position to an upper position adjacent to the lamp housing. This positional change in the vertical dimension places the guide bumper at the maximum load application point, improving load support effectiveness while the integration with the lamp housing maintains installation simplicity
4Strength
If additional reinforcing members are added to secure rigidity in perpendicular fastening directions, then structural strength is improved, but the overall weight of the assembly increases
Solution Approach 1:
The guide bumper member employs a composite material structure with rubber and steel. The rubber portion provides shock absorption and flexibility, while embedded steel reinforcement provides the necessary rigidity and strength. This composite approach achieves structural strength without adding excessive weight compared to using solid metal reinforcing members
Solution Approach 2:
The guide bumper function is merged with the lamp housing structure, eliminating the need for separate reinforcing members. The lamp housing itself is designed to provide the necessary structural support, reducing the overall weight of the assembly while maintaining required rigidity

AI summary
A tailgate guide bumper is to be installed between a tailgate that opens to a rear of a vehicle and a vehicle body of the vehicle to support the tailgate in a widthwise direction of the vehicle. The tailgate guide bumper includes a guide bumper member fastened to one side of the tailgate and a guide bumper supporting part configured to be in contact with the guide bumper member when the tailgate is closed to support load applied in a widthwise direction of the tailgate. The guide bumper member and the guide bumper supporting part are installed to be adjacent to a lamp installed at the rear of the vehicle.
