Three-Axis Position Adjustment for Display Module Alignment

Solution Overview

Problem

In large multi-display devices installed in public places, ensuring precise alignment of adjacent display modules is crucial for maintaining high image quality, as misalignment can lead to a fragmented viewing experience.

Innovation Solution

A position adjustment device comprising multiple direction control modules and controllers allows for precise alignment of display modules in a tiled arrangement by enabling movement in three perpendicular directions, ensuring seamless integration of adjacent screens.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of stationary object

If display modules are arranged in a tile arrangement to form a multi-display device, then the display area and resolution are improved, but the alignment precision between adjacent modules deteriorates

Engineering Contradiction:

Improvedisplay areaVSAvoidalignment precision

Core Design Contradiction:

Area of stationary objectVSManufacturing precision

Solution Approach 1:

The adjustment function is segmented into three independent direction control modules, each responsible for one of the three perpendicular directions. This segmentation allows precise control of alignment in each direction separately, resolving the alignment precision issue while maintaining the large display area achieved through tile arrangement.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

A position adjustment device is introduced as an intermediary mechanism between the display modules and the cabinet. This device includes three direction control modules with controllers that enable precise positioning and alignment of adjacent display modules, thereby improving alignment precision without compromising the overall display area.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Manufacturing precision

If a position adjustment device with three direction control modules is added to improve alignment precision, then the alignment precision is improved, but the device complexity increases

Engineering Contradiction:

Core Design Contradiction:

Manufacturing precisionVSDevice complexity

Solution Approach 1:

The adjustment function is segmented into three independent direction control modules, each responsible for one of the three perpendicular directions. This segmentation allows precise control of alignment in each direction separately, resolving the alignment precision issue while maintaining the large display area achieved through tile arrangement.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Each direction control module is designed as a universal unit that can be coupled to control movement in a specific direction. The modules share a common structure with a stage, controller, and coupling mechanism, allowing them to perform the same positioning function in different spatial directions. This multi-functionality reduces overall system complexity despite adding three-directional control capability.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Ease of operation

If multiple direction control modules with controllers are integrated into the cabinet, then the ease of operation for alignment is improved, but the device complexity increases

Solution Approach 2:

The position adjustment device enables operators to independently adjust each display module's position in three perpendicular directions using separate controllers. This self-service capability allows precise alignment to be achieved through simple operational inputs without requiring complex external adjustment mechanisms, thereby improving ease of operation.

Inventive Principle:

Principle #25Self-service
