Armrest adjuster
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional armrest adjusters have complex structures with many components, making assembly difficult and prone to separation or loss during transportation and assembly, which hampers production management and market competitiveness.
Innovation Solution
An armrest adjuster comprising a slider, a fixing member, and a button, where the fixing member is mounted into a concave space of the slider with pins and grooves, and a button with a rack system allows for horizontal adjustment of the armrest pad, simplifying assembly and production by integrating components into a modular unit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional armrest adjusters use multiple separate components (horizontal adjustment member, height adjustment member, bearing head), then the adjustment functionality is comprehensive, but the structure becomes complicated and assembly becomes troublesome
Solution Approach 1:
The patent combines the horizontal adjustment member and height adjustment member into a single integrated adjuster body. The bearing head is integrated directly onto this unified structure, eliminating the need for separate components. This merging maintains comprehensive adjustment functionality while significantly simplifying the overall structure and reducing the number of parts that need to be assembled.
Solution Approach 2:
The integrated adjuster body serves multiple functions simultaneously: it provides both horizontal and height adjustment capabilities, incorporates the bearing head for rotational movement, and includes the locking mechanism all within a single component. This multi-functionality approach eliminates the need for separate specialized components for each adjustment function.
2Ease of manufacture
If multiple separate components are assembled from top down or bottom up, then the armrest can be assembled, but the components may separate, loosen or lose during transportation or assembly due to direction change or inverted position
Solution Approach 1:
By merging the horizontal adjustment member, height adjustment member, and bearing head into a single integrated adjuster body, the patent eliminates the problem of components separating or loosening during transportation. The integrated structure remains stable regardless of orientation or handling, while still allowing for straightforward assembly onto the armrest support.
3Adaptability or versatility
If conventional armrest adjusters use more components and complicated structure, then the adjustment mechanism is functional, but the assembly process becomes time-consuming and inconvenient for mass production
Solution Approach 1:
The integration of multiple adjustment functions into a single adjuster body dramatically reduces assembly time and complexity. Instead of assembling multiple separate components in sequence, workers can install one unified component, thereby improving productivity and making the process more suitable for mass production while maintaining full adjustment functionality.
Solution Approach 2:
The patent segments the armrest system into two main parts: the integrated adjuster body (containing all adjustment mechanisms) and the armrest pad assembly. This segmentation allows the complex adjustment mechanism to be pre-assembled and tested as a complete unit, then easily installed as a single component, improving both assembly efficiency and quality control.

AI summary
An armrest adjuster includes a slider, a fixing member moveably mounted into a concave space of the slider, and a button is revealed. Two pins set on a bottom surface of the fixing member are moveably mounted in two long grooves on a bottom surface of the slider respectively. Each pin is set with a through hole for being fastened on a top of a vertical support of an armrest. The button exposed is clipped between the slider and the fixing member. The button is disposed with a rack while another rack corresponding to the rack of the button is arranged at the fixing member. The rack of the button is separated from the rack of the fixing member when the button is pressed. Thus the slider is moved horizontally relative to the fixing member. The design is beneficial to the assembly process, modularization and mass production.
