Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of stationary object

If multiple display panels are assembled in a tiled manner to create ultra-large display apparatus, then the display size can be increased, but visible seams and height discrepancies appear between panels

Engineering Contradiction:
Improvedisplay sizeVSAvoidpanel alignment precision
Core Design Contradiction:
Area of stationary objectVSManufacturing precision

Solution Approach 1:

The coupling structure is divided into multiple independent adjustment elements (height adjustment elements and position adjustment elements) that can be individually adjusted to control each display panel's position, enabling precise alignment while maintaining the ability to assemble large-scale displays from multiple panels

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The coupling structure incorporates adjustable mechanisms that allow dynamic modification of panel positions during assembly and maintenance, with height adjustment elements capable of moving along the vertical direction and position adjustment elements capable of moving along the horizontal direction to achieve seamless alignment

Inventive Principle:
Principle #15Dynamics

2Ease of manufacture

If conventional assembly methods are used to join display panels, then assembly is straightforward, but disassembly and replacement of defective panels is difficult

Engineering Contradiction:
Improveassembly simplicityVSAvoidpanel replacement ease
Core Design Contradiction:
Ease of manufactureVSEase of repair

Solution Approach 1:

The coupling structure replaces traditional mechanical fastening systems (screws, clips, adhesives) with magnetic coupling between the back frame and display panels, allowing panels to be easily attached and detached by simply approaching and separating the panels, significantly improving both assembly simplicity and repair ease

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Manufacturing precision

If display panels are tightly coupled to eliminate gaps, then seam visibility is reduced, but adjustment and alignment become more difficult

Engineering Contradiction:
Improveseam uniformityVSAvoidalignment ease
Core Design Contradiction:
Manufacturing precisionVSEase of operation

Solution Approach 1:

The coupling structure provides dynamic adjustment capabilities through height adjustment elements that move along the vertical direction and position adjustment elements that move along the horizontal direction, allowing operators to first align panels loosely and then precisely adjust positions to eliminate seam visibility while maintaining ease of operation

Inventive Principle:
Principle #15Dynamics
