Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If traditional assembly methods are used for micro polychrome light emitting device, then manufacturing process is simple, but alignment precision between displays deteriorates

Engineering Contradiction:

Improvealignment precisionVSAvoidcorrection process complexity

Core Design Contradiction:

Manufacturing precisionVSDevice complexity

Solution Approach 1:

The patent applies preliminary action by pre-calculating and storing compensation parameters in a look-up table before actual operation. The system determines rotational and shift compensation values in advance for various misalignment scenarios, allowing rapid correction during operation without complex real-time computation, thus improving alignment precision while maintaining operational simplicity

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent segments the image correction process into distinct components: rotational compensation and shift compensation. By dividing the correction task into separate manageable parts with dedicated compensation parameters, the system can address different types of misalignment independently, improving overall alignment precision without requiring a monolithic complex correction mechanism

Inventive Principle:

Principle #1Segmentation

2Manufacturing precision

If rotational compensation is applied to align displays, then imaging quality improves, but computational resource consumption increases

Engineering Contradiction:

Improveimaging qualityVSAvoidcomputational energy consumption

Core Design Contradiction:

Manufacturing precisionVSUse of energy by moving object

Solution Approach 1:

The patent significantly reduces computational energy consumption by performing all complex rotational compensation calculations in advance and storing results in a look-up table. During actual operation, the system only needs to retrieve pre-computed parameters based on measured misalignment values, transforming a computationally intensive real-time operation into a simple table lookup, thus maintaining high imaging quality while minimizing energy usage

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent replaces complex real-time computational mechanisms with a data retrieval mechanism. Instead of performing rotational mathematics operations during operation, the system substitutes computation with look-up table access, effectively replacing a computationally heavy process with a memory access operation that consumes minimal energy while achieving the same alignment correction goal

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Ease of manufacture

If multiple processing parts and curing processes are accumulated during assembly, then assembly steps are completed, but alignment deviation between displays increases

Engineering Contradiction:

Improveassembly completenessVSAvoidalignment accuracy

Core Design Contradiction:

Ease of manufactureVSManufacturing precision

Solution Approach 1:

The patent implements feedback by measuring the actual misalignment values after assembly and using these measurements to retrieve appropriate compensation parameters. The system continuously monitors alignment status and adjusts the correction approach based on actual conditions, allowing complete assembly processes while maintaining alignment accuracy through compensatory adjustments

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The patent compensates for assembly-induced alignment errors by changing the display parameters (rotational angle and shift amount) based on measured misalignment. Instead of modifying the physical assembly process, the system adjusts operational parameters to counteract the effects of accumulated assembly deviations, maintaining alignment accuracy despite multiple processing steps

Inventive Principle:

Principle #35Parameter changes
