Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If sensing units are used to detect light-emitting unit performance, then measurement precision is improved, but abnormal sensing values cause harmful effects on display quality

Engineering Contradiction:

Improvesensing precisionVSAvoidabnormal sensing values impact

Core Design Contradiction:

Measurement precisionVSObject-generated harmful factors

Solution Approach 1:

The patent identifies abnormal sensing values and converts them from harmful factors into beneficial information by using them as criteria for rearrangement. The control assembly rearranges light-emitting units based on sensing values, specifically placing units with abnormal sensing values away from each other, thereby transforming the harmful effect of abnormal values into a useful mechanism for improving display uniformity.

Inventive Principle:

Principle #22Blessing in disguise (Convert harm into benefit)

2Manufacturing precision

If light-emitting units with abnormal sensing values are adjusted individually, then manufacturing precision is improved, but device complexity increases

Engineering Contradiction:

Improvedisplay uniformityVSAvoidcontrol complexity

Core Design Contradiction:

Manufacturing precisionVSDevice complexity

Solution Approach 1:

The patent segments the adjustment process into two stages: first, identifying abnormal sensing values; second, rearranging light-emitting units based on these values. This segmentation allows the complex problem of display uniformity adjustment to be broken down into manageable steps, reducing control complexity while maintaining manufacturing precision.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The control assembly performs preliminary identification of abnormal sensing values before the rearrangement process. This preliminary action allows the system to prepare rearrangement strategies in advance, simplifying the actual adjustment process and reducing real-time control complexity while ensuring precise display uniformity.

Inventive Principle:

Principle #10Preliminary action
