Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If image processing operations are performed on digital images captured in varying conditions, then image enhancement capabilities are improved, but computational complexity increases

Engineering Contradiction:

Improveimage processing capabilityVSAvoidcomputational complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system performs preliminary actions by capturing metadata during the image capture phase that describes processing operations to be applied later. This includes pre-defining processing parameters, filters, and effects that will be applied in post-capture stages, thereby reducing the computational burden during actual processing by having preparation work done in advance.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent segments the image processing workflow into distinct stages: capture phase (metadata generation), transmission phase (sending original image and metadata), and post-processing phase (applying operations). This segmentation allows each stage to be optimized independently, reducing overall computational complexity while maintaining enhancement capabilities.

Inventive Principle:

Principle #1Segmentation

2Manufacturing precision

If post-capture image processing is performed with changing scales, noises, lighting, and geometric distortions, then image quality enhancement is improved, but processing time increases

Engineering Contradiction:

Improveimage qualityVSAvoidprocessing time

Core Design Contradiction:

Manufacturing precisionVSLoss of time

Solution Approach 1:

Processing parameters and metadata are prepared in advance during image capture, including information about expected transformations for handling scales, noises, lighting, and geometric distortions. This preliminary preparation reduces the time required during actual post-capture processing by having a predefined processing plan ready.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent replaces complex real-time mechanical image processing with a streamlined system that uses pre-defined processing operations and metadata-driven transformations. This substitution reduces processing time by avoiding complex iterative adjustments during post-capture stages.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Ease of operation

If media overlays are applied in post-processing stages, then user experience is improved, but system latency is reduced only with optimized pipelines

Engineering Contradiction:

Core Design Contradiction:

Ease of operationVSLoss of time

Solution Approach 1:

The system implements a universal extensible graphical rendering pipeline that handles multiple functions including media overlay application, image processing, and effect rendering through a single optimized architecture. This multi-functional pipeline reduces latency by avoiding multiple separate processing passes and enables efficient media overlay application in post-processing stages.

Inventive Principle:

Principle #6Universality (Multi-functionality)
