Vehicle Seat Backrest Carrier With Integrated Positioning and Latching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle seat backrests are heavy, require multiple components, and have complex assembly processes due to the use of screw connections, rivet connections, and material-bonded connections.
Innovation Solution
A carrier structure for a vehicle seat backrest featuring a positioning element on the carrier top side with openings for a headrest holder and latching elements on the carrier underside or lateral sides, allowing for a simplified assembly process without separate fastening elements like screws, rivets, or welding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional screw connections and separate fastening elements are used to attach the carrier structure to the backrest frame, then the connection strength and reliability are improved, but the weight of the backrest increases and the assembly process becomes more complex
Solution Approach 1:
The patent integrates the positioning element and latching element directly into the carrier structure as integral components, merging the functions of positioning, orientation, and fastening into a single unified structure. This eliminates the need for separate screws and fastening elements, reducing weight while maintaining connection reliability through the combined mechanical action of the integrated elements
Solution Approach 2:
The latching element acts as an intermediary mechanism between the carrier structure and the backrest frame, providing a reliable connection through a simplified interface. The latching element engages with the frame to secure the carrier structure, achieving strong connection reliability without requiring traditional screw fastening
2Reliability
If multiple separate connecting elements such as screws and fastening elements are used, then the connection reliability is improved, but the number of components increases and assembly time increases
Solution Approach 1:
The patent combines multiple functions (positioning, orientation, and fastening) into integrated elements that are part of the carrier structure itself. The positioning element and latching element are formed as integral parts of the carrier structure, eliminating the need for multiple separate connecting elements and reducing overall component complexity while maintaining connection reliability
Solution Approach 2:
The carrier structure is designed with multi-functional integrated elements that simultaneously perform positioning, orientation, and fastening functions. The positioning element provides both positioning and structural support, while the latching element provides both connection and securing functions, reducing the need for specialized separate components
3Strength
If traditional mounting methods with separate fastening elements are used, then the connection strength is improved, but the assembly time and manufacturing complexity increase
Solution Approach 1:
The positioning element and latching element are pre-integrated into the carrier structure during manufacturing, so that no additional fastening elements need to be installed during assembly. The carrier structure arrives at the assembly site already prepared with its positioning and latching functions built-in, eliminating time-consuming fastening operations while maintaining connection strength
Solution Approach 2:
By merging the positioning and fastening functions into integral elements of the carrier structure, the patent eliminates the need for separate assembly steps involving screws and fastening elements. The integrated design allows for quicker installation while maintaining the necessary connection strength through the combined mechanical action of the integrated elements
