Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fastening arrangements for vehicle headrests are complex and expensive, with a high risk of incorrect assembly leading to potential injury due to the use of multiple individual parts and locking bolts.
Innovation Solution
A fastening arrangement with a base body and integrally connected fastening element, such as a pivoting fastening strap, that simplifies assembly by eliminating the need for separate fastening elements and ensures correct positioning, reducing the risk of incorrect assembly and manufacturing costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple individual parts and locking bolts are used to fasten the base body to the retaining rod, then the fastening can be achieved, but the assembly becomes complex and expensive
Solution Approach 1:
The patent combines multiple separate fastening components (base body, fastening element, locking mechanism) into a single integrally connected base body. The fastening element is formed as one piece with the base body, eliminating the need for separate locking bolts and reducing assembly complexity while maintaining fastening security.
Solution Approach 2:
The base body is functionally segmented into distinct regions: a base body region for structural support and a fastening element region for securing the retaining rod. This functional segmentation allows each region to be optimized for its specific purpose while being manufactured as a single integrated component.
2Reliability
If multiple individual parts and locking bolts are used, then the fastening can be achieved, but the risk of incorrect assembly increases
Solution Approach 1:
The fastening element is pre-positioned and integrally connected to the base body during manufacturing, ensuring correct alignment and positioning before assembly. This preliminary action eliminates the risk of incorrect assembly of separate fastening components and ensures precise positioning during the assembly process.
3Reliability
If separate fastening elements are manufactured and assembled, then the fastening can be achieved, but the manufacturing costs increase
Solution Approach 1:
The base body and fastening element are manufactured as a single integrated component, eliminating the need for separate manufacturing processes and assembly operations. This merging of components reduces manufacturing costs while ensuring reliable fastening security through the integral connection.
