Solution Overview

Problem

Existing display devices lack the ability to freely adjust the angle or height of the display panel, and do not provide various motion operations.

Innovation Solution

A display device with a support arm system comprising an inner and outer arm, connected by a supporter with an elastic member, allowing for adjustable tilt and height adjustment, and a rotatable connector for pivoting the display panel.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a fixed support structure is used for the display panel, then the structure is simple and stable, but the display panel cannot be adjusted in angle or height

Engineering Contradiction:
Improveadjustability of display panel angle and heightVSAvoidcomplexity of support structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The support arm is divided into multiple segments (first support arm, second support arm, third support arm) connected by rotation units, allowing each segment to be independently adjusted. This segmentation enables the display panel to achieve multiple positions and angles while keeping each individual component relatively simple in structure.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The support structure transitions from a fixed rigid structure to a dynamic adjustable structure through the incorporation of rotation units with elastic members. These rotation units allow the support arms to rotate and adjust angles dynamically, providing adaptability while the elastic members maintain structural stability during adjustments.

Inventive Principle:
Principle #15Dynamics

2Ease of operation

If a support arm system with multiple arms and rotation units is used, then the display panel can be adjusted freely, but the device complexity increases

Engineering Contradiction:
Improveease of adjusting display panel position and angleVSAvoidnumber of components in support arm system
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

Multiple functions are merged into the rotation units, which combine rotation capability, elastic member for maintaining position, and connection between support arms. This merging reduces the total number of separate components needed while maintaining ease of operation for adjusting the display panel.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The elastic members in the rotation units automatically maintain the display panel at adjusted positions without requiring additional locking mechanisms or complex control systems. The elastic force naturally holds the arms in their adjusted positions, making the system easy to operate while reducing component complexity.

Inventive Principle:
Principle #25Self-service

3Reliability

If an elastic member is added to the support arm, then the display panel can maintain adjusted positions stably, but the device complexity increases

Engineering Contradiction:
Improvestability of adjusted display panel positionVSAvoidcomplexity of support arm components
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The elastic members change the mechanical parameters of the support arm system by introducing elastic force that can be compressed or extended. This parameter change allows the system to maintain stable adjusted positions through elastic resistance, while the elastic members themselves remain relatively simple components that integrate into the existing support arm structure.

Inventive Principle:
Principle #35Parameter changes
