Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of stationary object

If multiple display panels are arranged with large distances between them, then each panel has sufficient space for supporting structures, but the effective use area is reduced and space utilization becomes inefficient

Engineering Contradiction:

Improveeffective use areaVSAvoidsupporting structure space

Core Design Contradiction:

Area of stationary objectVSDevice complexity

Solution Approach 1:

The patent merges multiple display panels into a spliced configuration where they share common supporting structures (optical film, transparent cover plate, filling structure). This consolidation reduces the total space required for supporting structures while increasing the effective display area, directly resolving the contradiction between area utilization and structural support requirements.

Inventive Principle:

Principle #5Merging (Combining)

2Area of stationary object

If display panels are placed closer together to improve space utilization, then space efficiency increases, but water, oxygen, and dust intrusion becomes more likely, affecting reliability

Engineering Contradiction:

Improvespace utilizationVSAvoidprotection against water, oxygen, and dust intrusion

Core Design Contradiction:

Area of stationary objectVSReliability

Solution Approach 1:

The patent employs a filling structure that acts as a sealing barrier between spliced display panels. This flexible sealing mechanism prevents water, oxygen, and dust from intruding through the gaps between closely placed panels, thereby maintaining reliability while enabling high space utilization.

Inventive Principle:

Principle #30Flexible shells and thin films

3Area of stationary object

If display panels are spliced with minimal distance between them, then space utilization is optimized, but the complexity of preventing harmful factor intrusion increases

Engineering Contradiction:

Improvespace utilizationVSAvoidsealing structure complexity

Core Design Contradiction:

Area of stationary objectVSDevice complexity

Solution Approach 1:

The filling structure uses a flexible sealing design that can adapt to the spliced configuration of display panels. This approach provides effective protection against harmful factors without requiring complex multi-layer sealing systems, thus optimizing space utilization while controlling structural complexity.

Inventive Principle:

Principle #30Flexible shells and thin films

4Area of moving object

If the distance between display panels is reduced, then the overall display area increases, but the risk of environmental contamination increases

Engineering Contradiction:

Improvedisplay areaVSAvoidwater, oxygen, and dust contamination

Core Design Contradiction:

Area of moving objectVSObject-affected harmful factors

Solution Approach 1:

The filling structure creates a protective barrier between closely spaced display panels, preventing water, oxygen, and dust from contaminating the display areas. This enables the system to maintain large display areas with minimal panel spacing while effectively blocking environmental harmful factors.

Inventive Principle:

Principle #30Flexible shells and thin films
