Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If traditional folding structures are used to enable screen flexibility, then the screen can be folded and transported, but gaps appear between adjacent unit modules affecting display quality

Engineering Contradiction:
Improvefolding capabilityVSAvoidsplicing precision
Core Design Contradiction:
Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The screen is divided into independent unit modules that can be separately assembled and disassembled. Each module contains LED components and structural elements, allowing the screen to be segmented for folding while maintaining precise edges for gapless splicing when assembled

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

A splicing structure with positioning elements acts as an intermediary between adjacent unit modules. This intermediary component ensures precise alignment and contact between modules, eliminating gaps while allowing the overall structure to be folded for transport

Inventive Principle:
Principle #24Intermediary (Mediator)

2Stability of the object's composition

If complex connecting mechanisms are used to join unit modules, then the screen can be assembled, but the connecting operability becomes complicated and time-consuming

Engineering Contradiction:
Improvemodule connection stabilityVSAvoidassembly convenience
Core Design Contradiction:
Stability of the object's compositionVSEase of operation

Solution Approach 1:

The connection system is segmented into simple positioning elements and corresponding receptacles on each module. This segmentation allows modules to be joined through simple alignment and engagement rather than complex mechanisms, improving assembly convenience while maintaining stability

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The splicing structure incorporates self-positioning elements that automatically align modules during assembly. The modules self-align through geometric constraints and positioning features, eliminating the need for complex alignment procedures or specialized tools

Inventive Principle:
Principle #25Self-service

3Manufacturing precision

If unit modules are tightly connected to eliminate gaps, then display effect is improved, but maintenance and replacement of damaged modules becomes difficult

Engineering Contradiction:
Improvesplicing precisionVSAvoidmodule replacement ease
Core Design Contradiction:
Manufacturing precisionVSEase of repair

Solution Approach 1:

The screen is segmented into independently connected modules with standardized interfaces. This segmentation allows individual modules to be removed and replaced without affecting the integrity of adjacent modules, facilitating maintenance while maintaining precise splicing through the standardized connection structure

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The connection structure is designed with preliminary positioning features that guide module alignment during assembly and disassembly. The positioning elements are pre-configured to ensure precise splicing is automatically achieved when modules are connected, making replacement simple while maintaining display quality

Inventive Principle:
Principle #10Preliminary action
