Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of stationary object

If multiple small-sized display modules are disposed adjacent to one another to create a large-sized screen, then the screen size is increased, but the alignment precision and structural stability deteriorate due to the complexity of assembling multiple modules

Engineering Contradiction:
Improvescreen sizeVSAvoidmodule alignment precision
Core Design Contradiction:
Area of stationary objectVSManufacturing precision

Solution Approach 1:

The large display system is segmented into multiple independent display modules, each with its own frame and support structure. This allows each module to be manufactured and aligned separately, then assembled using the spacer-based positioning system, thereby maintaining alignment precision while achieving large overall screen area.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

A spacer structure serves as an intermediary component between adjacent display modules. The spacer includes positioning protrusions that fit into corresponding recesses on the modules, acting as a mechanical mediator that ensures precise alignment and stable positioning without requiring complex direct coupling between modules.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Area of stationary object

If display modules are assembled adjacent to one another, then the screen area is expanded, but the structural stability deteriorates due to the increased number of connection points and potential misalignment

Engineering Contradiction:
Improvescreen areaVSAvoidstructural stability
Core Design Contradiction:
Area of stationary objectVSStability of the object's composition

Solution Approach 1:

The spacer structures are pre-formed with specific geometric features (protrusions and recesses) that predetermined the alignment and positioning of modules before assembly. This preliminary preparation ensures that when modules are assembled, they automatically achieve correct positioning, maintaining structural stability across the expanded screen area.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The spacer design employs asymmetric geometric features where protrusions on one spacer correspond to recesses on adjacent modules in a non-symmetric arrangement. This asymmetric coupling ensures unique, stable positioning and prevents misalignment, thereby maintaining structural integrity as the screen area expands through additional modules.

Inventive Principle:
Principle #4Asymmetry

3Stability of the object's composition

If a secure mounting system is implemented for display modules, then the structural stability is improved, but the device complexity increases due to additional mounting components and assembly steps

Engineering Contradiction:
Improvestructural stabilityVSAvoidmounting system complexity
Core Design Contradiction:
Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The mounting function is merged with the spacer structure itself. The spacer simultaneously serves as a spacing element and a mounting component, with its protrusions and recesses providing both the gap maintenance and the secure mechanical coupling. This integration eliminates the need for separate mounting hardware, reducing overall system complexity while maintaining stability.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The spacer structure performs multiple functions: it maintains the physical gap between adjacent display modules, provides positioning alignment through its geometric features, and secures the modules together through its protrusion-recess coupling mechanism. This multi-functionality reduces the number of separate components needed, thereby simplifying the overall mounting system while ensuring structural stability.

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

A multi-display device includes a main frame, a plurality of module supporters disposed on the main frame, a plurality of display modules which are hung on the plurality of module supporters, and a spacer positioned between the two adjacent display modules. Each of the plurality of display modules includes a display panel. The spacer includes a base plate extending in a width direction of the display modules, a first protrusion extending from a first surface of the base plate, and a second protrusion extending from a second surface opposite the first surface of the base plate. The base plate includes a portion which protrudes further than the two adjacent display modules in the width direction of the display modules.
