Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current headrest height-adjustable mechanisms for automobile seats without headrest rods are complex, have many parts, and occupy large space, making assembly and disassembly processes complicated and inconvenient.
Innovation Solution
A movable headrest module with a first part and a second part, where the second part is supported by the first part and includes a moving component driven by a driving part, allowing for height adjustment and mounting to a seat frame through simple connecting interfaces, reducing the number of parts and simplifying assembly and disassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a height-adjustable headrest mechanism is integrated into the headrest with headrest rod, then the headrest can be adjusted to different heights, but the structure becomes complex with many parts and occupies large space
Solution Approach 1:
The headrest assembly is divided into separate modules: the headrest body, the moving component with slide rail configuration, and the driving part. This segmentation allows each module to be optimized independently and simplifies the overall structure by eliminating the need for integration into a single complex assembly
Solution Approach 2:
The height-adjustable mechanism is extracted from the traditional headrest rod integration and implemented as a separate moving component with slide rail configuration. This extraction reduces the complexity of the headrest structure while maintaining the height adjustment functionality
2Adaptability or versatility
If a height-adjustable headrest mechanism is integrated into the headrest with headrest rod, then the headrest can be adjusted to different heights, but the assembly process becomes complicated and disassembly is inconvenient
Solution Approach 1:
The modular design with separate first part, second part, and moving component allows for simplified assembly where components can be independently manufactured and then assembled together using standardized connecting interfaces, reducing assembly complexity
Solution Approach 2:
The connecting interfaces are designed to be universal, allowing the same interface structure to be used for both assembly and disassembly operations. This universality simplifies the manufacturing process and makes maintenance easier
3Adaptability or versatility
If a height-adjustable headrest mechanism is integrated into the headrest with headrest rod, then the headrest can be adjusted to different heights, but the space occupied increases
Solution Approach 1:
The moving component is designed to nest within the headrest assembly when not in use, and the slide rail configuration allows compact packaging of the moving parts. This nesting approach minimizes the space occupied while maintaining full height adjustment capability
