Pivotable Vehicle Armrest with Longitudinal Displacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle armrest designs lack sufficient ergonomic adaptability and flexibility to meet the diverse needs of users, limiting comfort and utilization of passenger compartment space.
Innovation Solution
An armrest arrangement with a pivotable and adjustable design, featuring a mounting fitting and armrest body that can be releasably attached and adjusted in multiple positions, including various angles and displacement paths, equipped with a locking mechanism and coding system to prevent misinstallation, allowing for enhanced ergonomic adaptation and easy removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the armrest body is made fixed and non-adjustable, then the device complexity is reduced, but the ergonomic adaptability and comfort are worsened
Solution Approach 1:
The armrest body is designed with dynamic adjustment capabilities, allowing it to pivot about a pivot axis and displace along the longitudinal direction. This enables the armrest to adapt to different ergonomic requirements while maintaining a relatively simple overall structure through controlled mobility rather than fixed rigidity.
Solution Approach 2:
The armrest arrangement is divided into separable components: the armrest body with trunk and support element, and the mounting fitting. This segmentation allows independent optimization of each component and simplifies the adjustment mechanism by separating the mounting function from the adjustment function.
2Adaptability or versatility
If the armrest body is made removable and adjustable, then the ergonomic adaptability and flexibility are improved, but the device complexity increases
Solution Approach 1:
The mounting fitting serves multiple functions: it provides the pivot axis for rotation, allows longitudinal displacement, and enables removable mounting. This multi-functionality reduces the need for separate mechanisms for each adjustment type, thereby limiting the increase in device complexity despite the high flexibility gained.
Solution Approach 2:
The armrest body is designed to move in multiple dimensions: rotation about a pivot axis (angular dimension) and displacement along the longitudinal direction (linear dimension). This multi-dimensional adjustment capability provides comprehensive ergonomic adaptability while using a integrated mounting fitting rather than separate mechanisms for each degree of freedom.
3Adaptability or versatility
If multiple adjustment positions are provided, then the ergonomic adaptability is improved, but the ease of operation is worsened due to complexity
Solution Approach 1:
The armrest body can pivot continuously or to multiple discrete positions about the pivot axis and displace continuously or to multiple positions along the longitudinal direction. This dynamic design allows users to adjust to precise ergonomic positions while maintaining ease of operation through natural movement rather than complex mechanical locking at each position.

AI summary
An armrest arrangement for a vehicle seat includes a mounting fitting to be mounted on a vehicle seat, and an armrest body having a trunk and a support element having an arm support surface for receiving an arm of a user when using the armrest arrangement. The armrest body having the trunk can be detachably attached to the mounting fitting. When mounted on the mounting fitting, the armrest body is pivotable about an axis of rotation with respect to the mounting fitting. The support element can be displaced with the arm support surface relative to the trunk in a longitudinal extension direction of the trunk.
