Multi-Directional Adjustable Armrest Pad for Hand Posture Adaptability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional armrests in chairs primarily offer height adjustments, which are insufficient for user comfort, as they do not account for varying hand postures and actions, necessitating a more comprehensive adjustment mechanism for optimal hand placement.
Innovation Solution
A multi-directional adjustable armrest pad with a base plate, pad body, and slide control assembly that allows longitudinal, lateral, and rotational adjustments, utilizing a locking pin, press control member, and horizontal sliding shaft set to enable precise positioning and movement of the pad body relative to the chair armrest.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If only height adjustment is provided for armrests, then the structure remains simple, but user comfort for different hand postures and actions is insufficient
Solution Approach 1:
The armrest pad is designed with multi-directional adjustability including longitudinal movement, lateral movement, and rotational capability. The slide control assembly enables the pad to dynamically adapt to different hand positions and postures, transforming a static armrest into a dynamic positioning system that responds to user needs.
Solution Approach 2:
The invention adds multiple adjustment dimensions beyond simple height adjustment. The pad can move longitudinally along the armrest, laterally across the armrest surface, and rotate to accommodate various hand orientations. This multi-dimensional adjustment capability comprehensively addresses different hand postures and actions.
2Adaptability or versatility
If longitudinal and lateral adjustment of pad is provided, then different arm lengths are accommodated, but various hand postures due to different operating actions cannot be satisfied
Solution Approach 1:
The rotational adjustment capability allows the pad to dynamically change its orientation angle, enabling users to position their hands in various postures required by different operating actions. This dynamic angular adjustment complements the longitudinal and lateral movements to provide comprehensive hand posture support.
3Ease of operation
If multi-directional adjustment mechanism is added to armrest pad, then user comfort for various hand postures is improved, but device complexity increases
Solution Approach 1:
The slide control assembly is designed to be user-operated through intuitive controls, allowing users to independently adjust the pad to their preferred position and posture without requiring complex manual intervention or professional installation. The mechanism serves itself by providing self-contained adjustment capabilities within easy reach of the user.
