Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If different image capture conditions are set for different regions, then imaging quality is improved, but device complexity increases

Engineering Contradiction:
Improveimaging qualityVSAvoiddevice complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The imaging device divides the imaging element into multiple blocks, where each block can be independently controlled with different image capture conditions. This segmentation allows region-specific optimization without requiring complete system redesign, thus improving imaging quality while managing complexity through modular organization.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Different image capture conditions (exposure, gain, integration time) are applied to different blocks based on local scene requirements. This local quality approach ensures that each region is captured with optimal settings for its specific characteristics, improving overall imaging quality without uniformly increasing complexity across the entire device.

Inventive Principle:
Principle #3Local quality

2Measurement precision

If region-specific image processing is performed, then image accuracy is improved, but processing time increases

Engineering Contradiction:
Improveimage accuracyVSAvoidprocessing time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The image processing is segmented by block, with each block processed independently using its specific capture conditions. This allows parallel processing of different regions, improving image accuracy through localized optimization while minimizing processing time through concurrent execution rather than sequential handling.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Image capture conditions are determined and set for each block before the actual image capture. This preliminary action allows the processing pipeline to be pre-configured for each region, reducing real-time processing complexity and time while maintaining high image accuracy through region-specific parameters.

Inventive Principle:
Principle #10Preliminary action

3Adaptability or versatility

If multiple image capture conditions are applied, then adaptability is improved, but control complexity increases

Engineering Contradiction:
ImproveadaptabilityVSAvoidcontrol complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The control system is segmented to manage image capture conditions at the block level rather than requiring global control. Each block can be independently configured with appropriate conditions, improving adaptability to different scene regions while simplifying control complexity through decentralized, modular management of capture parameters.

Inventive Principle:
Principle #1Segmentation
