Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional tailgates face challenges in maintaining the closed position during and after an accident due to breakage in the region around the tailgate lock, which can lead to safety and mechanical issues.
Innovation Solution
A tailgate with a main body made from injection-molded fiber-reinforced plastics material and at least one fiber-reinforced plastics material tape embedded or disposed on the main body, featuring a loop around a connection portion of an additional component for enhanced load-transmitting and load-distributing properties, ensuring secure anchoring and reinforcement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional assemblies of various components and materials are used to construct tailgates, then diverse construction features and functions (lights, brake lights, joints, rear window, safety properties) can be combined, but the construction becomes complex and the region around the tailgate lock becomes critical for breakage
Solution Approach 1:
The patent combines multiple construction features into a single integrated tailgate component made from fiber-reinforced plastics material. The tailgate lock region is integrated directly into the molded structure with reinforcement elements, eliminating the need for separate components and assemblies, thereby reducing construction complexity while maintaining diverse functions
Solution Approach 2:
The patent uses fiber-reinforced plastics material with integrated reinforcement elements to create a tailgate that maintains structural integrity and safety properties. The composite material structure provides the necessary strength and rigidity in the tailgate lock region while allowing integration of multiple construction features
2Stability of the object's composition
If the tailgate is made from fiber-reinforced plastics material with integrated reinforcement, then the structure becomes lighter and more stable, but the manufacturing process becomes more specialized
Solution Approach 1:
The reinforcement elements are pre-positioned and integrated into the mold cavity before the fiber-reinforced plastics material is injected. This preliminary action ensures proper placement and orientation of reinforcement elements, achieving structural stability while simplifying the manufacturing process by eliminating post-assembly steps
Solution Approach 2:
The patent merges the reinforcement elements with the tailgate body in a single integrated molding process. The reinforcement elements are embedded within the fiber-reinforced plastics material during injection molding, creating a unified structure that is both stable and manufacturable in one process step
3Strength
If additional components are embedded in the main body with fiber-reinforced tapes guided around connection portions, then load-transmitting and load-distributing properties improve, but the number of components and assembly steps increases
Solution Approach 1:
The patent integrates additional components and fiber-reinforced tapes directly into the molded tailgate structure. The tapes are positioned and embedded during the injection molding process, creating load-transmitting pathways that are built-in rather than assembled, thereby improving strength without increasing the number of separate components
Solution Approach 2:
The patent uses fiber-reinforced plastics material with embedded additional components to create integrated load-transmitting structures. The fiber reinforcement and additional components work together as a composite system within the molded structure, improving load distribution while maintaining a unified component design

AI summary
A tailgate, for a motor vehicle, has a main body made from an injection-molded fiber-reinforced plastics material, and at least one fiber-reinforced plastics material tape that is disposed on the main body. In order for a tailgate having improved load transmission and load distribution properties to be provided, the tailgate has at least one additional component which is at least partially embedded in the main body and which has at least one connection portion around which a loop of the fiber-reinforced plastics material tape is guided.
