Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If high-quality video content with increasing resolution and contrast levels is created, then video quality is improved, but computational resources, storage space, and bandwidth requirements increase

Engineering Contradiction:
Improvevideo qualityVSAvoidstorage space
Core Design Contradiction:
Manufacturing precisionVSQuantity of substance

Solution Approach 1:

The patent applies parameter changes by dynamically adjusting the deblocking filtering strength based on the splitting parameter of video blocks. By modifying the filtering intensity according to block characteristics (e.g., larger blocks receive stronger filtering), the system achieves better compression efficiency and reduced storage requirements while maintaining visual quality, thus resolving the contradiction between video quality and storage space.

Principle #35Parameter changes

2Manufacturing precision

If high-quality video content with increasing resolution and contrast levels is created, then video quality is improved, but computational resources for encoding and processing increase

Engineering Contradiction:
Improvevideo qualityVSAvoidcomputational resources
Core Design Contradiction:
Manufacturing precisionVSUse of energy by moving object

Solution Approach 1:

The patent implements local quality by applying deblocking filtering selectively based on the splitting parameter of each video block. Instead of uniformly processing all blocks with the same filtering strength, the system adapts the filtering intensity to local block characteristics (e.g., applying stronger filtering to larger blocks and weaker filtering to smaller blocks). This localized approach reduces overall computational resources while maintaining video quality.

Inventive Principle:
Principle #3Local quality

3Manufacturing precision

If high-quality video content with increasing resolution and contrast levels is created, then video quality is improved, but bandwidth requirements to deliver video content increase

Engineering Contradiction:
Improvevideo qualityVSAvoidbandwidth
Core Design Contradiction:
Manufacturing precisionVSQuantity of substance

Solution Approach 1:

The patent utilizes parameter changes by dynamically adjusting deblocking filtering based on splitting parameters, which improves compression efficiency. By optimizing the filtering strength according to block characteristics, the system reduces the bitrate required to deliver high-quality video content, thereby lowering bandwidth requirements while maintaining video quality.

Inventive Principle:
Principle #35Parameter changes

4Quantity of substance

If deblocking filtering is applied to reduce compressed video size, then storage and bandwidth are saved, but video quality may be degraded due to over-filtering

Engineering Contradiction:
Improvecompressed video sizeVSAvoidvideo quality
Core Design Contradiction:
Quantity of substanceVSManufacturing precision

Solution Approach 1:

The patent resolves this contradiction by dynamically changing the filtering parameter based on the splitting parameter of each video block. By adjusting the deblocking filtering strength adaptively (e.g., stronger filtering for larger blocks, weaker filtering for smaller blocks), the system achieves optimal compression while preserving video quality and avoiding over-filtering artifacts.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent applies local quality by making the deblocking filtering intensity location-dependent based on block splitting characteristics. Different regions of the video are filtered with appropriate strength tailored to their specific block structures, ensuring that compression efficiency is maximized without degrading video quality in any particular region.

Inventive Principle:
Principle #3Local quality
