Vehicle Headrest Mounting Structure With Integrated Holding Tube
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing headrests for vehicle seats are complex to assemble and heavy due to separate holding and connecting means, which increases manufacturing costs and weight.
Innovation Solution
Integration of holding and connecting means into a single piece, with the connecting means being formed from the holding means, preferably in a tubular form, and manufactured from metal, allowing for a unified structure that simplifies assembly and reduces weight by eliminating the need for additional components and enhancing the connection through angled regions and laser welding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If holding means and connecting means are provided as separate components, then assembly flexibility and ease of repair are improved, but device complexity and weight increase
Solution Approach 1:
The patent combines the holding means and connecting means into a single integrated component made from one piece of metal. This merging eliminates the need for separate parts and their associated fastening operations, directly reducing device complexity while maintaining assembly functionality through the unified structure's ability to perform both holding and connecting functions simultaneously
2Ease of repair
If multiple separate components are used, then ease of repair and replacement are improved, but weight and manufacturing cost increase
Solution Approach 1:
The integrated design merges holding means and connecting means into one piece, eliminating redundant material and fastening hardware. This reduces overall weight while the unified structure can still be replaced as a single unit, maintaining repairability through simplified part inventory and installation
Solution Approach 2:
The single integrated component performs multiple functions simultaneously - it holds the holding rod and connects to the vehicle frame. This multi-functionality eliminates the need for separate specialized components, reducing total weight while maintaining all necessary functions in one universal part
3Device complexity
If holding means and connecting means are integrated in one piece, then weight and assembly complexity are reduced, but manufacturing precision requirements increase
Solution Approach 1:
The patent employs laser welding technology to join sections of the integrated component with high precision. This manufacturing parameter change enables accurate integration of holding and connecting functions in one piece, achieving the required manufacturing precision through advanced joining methods that maintain tight tolerances for proper headrest operation
4Reliability
If separate connecting means are used, then connection strength and reliability are improved, but weight and assembly time increase
Solution Approach 1:
By merging holding means and connecting means into one integrated component, the patent eliminates the time required to separately install and fasten connecting means. The unified structure is installed as a single unit, reducing assembly time while maintaining connection reliability through the continuous metal structure and laser-welded joints that provide robust attachment to the vehicle frame
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The integrated design streamlines assembly, reduces weight, and strengthens the connection between the headrest and the vehicle seat frame, resulting in a lighter and easier-to-assemble headrest with improved structural integrity.
Implementation Method 1
The laser beam in this case is preferably directed at the angled region 3.1 (cf. FIG. 2) of the connecting means 3
