Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If each LED module is equipped with its own driving chip, then the reliability and ease of operation are improved, but the device complexity and manufacturing cost increase

Engineering Contradiction:

Improvedriving reliabilityVSAvoiddriving chip arrangement complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The driving chip is designed to perform multiple functions by controlling LED arrays across different modules. A single driving chip can drive the LED array of its own module as well as LED arrays of adjacent modules, reducing the total number of driving chips needed while maintaining system reliability through centralized control capability

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Ease of manufacture

If the number of driving chips is reduced, then the manufacturing cost decreases, but the device complexity increases due to optimized arrangement requirements

Engineering Contradiction:

Improvemanufacturing costVSAvoiddriving chip arrangement

Core Design Contradiction:

Ease of manufactureVSDevice complexity

Solution Approach 1:

Adjacent LED modules are merged in terms of driving control, where one driving chip serves multiple modules. This consolidation reduces the total number of driving chips required, lowering manufacturing costs while the systematic arrangement method keeps the complexity manageable through standardized positioning patterns

Inventive Principle:

Principle #5Merging (Combining)

3Quantity of substance

If driving chips are arranged to serve multiple LED modules, then the integration density improves, but the arrangement optimization difficulty increases

Engineering Contradiction:

Improvedriving chip quantityVSAvoidarrangement optimization

Core Design Contradiction:

Quantity of substanceVSDevice complexity

Solution Approach 1:

The display system is segmented into first LED modules with driving chips and second LED modules without driving chips. This segmentation allows clear identification of which modules contain driving chips and which rely on shared driving, simplifying the arrangement optimization by establishing a systematic pattern rather than requiring individual optimization for each module

Inventive Principle:

Principle #1Segmentation
