Solution Overview

Problem

Conventional console armrests in vehicles either lack height adjustment, leading to inadequate support for passengers of varying physical conditions, or rely on tilting which incompletely supports the arm, causing discomfort.

Innovation Solution

A device with a vertically movable upper body assembly and a linear guide system, including lead screws and rails, allows for adjustable height of the armrest while maintaining a horizontal position, enabling comfortable arm support tailored to individual passenger needs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the armrest is made fixed in height, then the structure is simple, but the passenger's arm cannot be supported comfortably according to different physical conditions

Engineering Contradiction:
Improvearm support comfortVSAvoidstructure complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The armrest is transformed from a fixed structure to a dynamically adjustable one. The upper body assembly can be vertically moved along the lower body assembly through the linear guide mechanism, allowing the armrest height to be adjusted according to different passenger needs while maintaining structural control through guides and lead screws

Inventive Principle:
Principle #15Dynamics

2Ease of operation

If the armrest is tilted to adjust height, then height adjustment is achieved, but the arm cannot be entirely comfortably supported

Engineering Contradiction:
Improvearm support comfortVSAvoidarmrest orientation
Core Design Contradiction:
Ease of operationVSShape

Solution Approach 1:

The armrest transitions from a static tilted position to a dynamically adjustable vertical position. The upper body assembly moves vertically along the lower body assembly while maintaining horizontal orientation through the linear guide system, ensuring the armrest remains level at any height for optimal arm support

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

Instead of adjusting armrest height through tilting (angular adjustment in one dimension), the invention moves the upper body assembly vertically (linear adjustment in a different dimension). This vertical translation along the guide rails maintains the armrest's horizontal orientation while achieving height adjustment, providing better arm support

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Ease of operation

If the upper body assembly is made vertically movable, then height adjustment is achieved while maintaining horizontal state, but the device complexity increases

Engineering Contradiction:
Improvearm support comfortVSAvoidmechanism complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The console is divided into separate assemblies: the lower body assembly (fixed) and the upper body assembly (movable). This segmentation allows the upper body containing the armrest to be independently adjusted vertically while the lower body remains stationary, simplifying the control mechanism compared to moving the entire console

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The linear guide system acts as an intermediary mechanism between the fixed lower body and the movable upper body. The guides and lead screws provide a controlled interface that enables smooth vertical movement while maintaining horizontal alignment, reducing the complexity that would otherwise be required to directly connect and move the upper body

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

Provided herein is a device for adjusting a height of a console in a vehicle. The console is configured with an upper body assembly (10) having an armrest (13), and a lower body assembly (20), and a linear guide is provided between the upper body assembly (10) and the lower body assembly (20), and a motor (50) operates the linear guide, so that the upper body assembly 10 can be vertically moved. Therefore, a height of the armrest 13 can be freely adjusted according to a passenger's physical condition.
