Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If dataform decoding is performed in existing computing devices, then scanning functionality is added, but processor intensity and battery consumption increase

Engineering Contradiction:

Improvescanning functionalityVSAvoidbattery consumption

Core Design Contradiction:

Adaptability or versatilityVSUse of energy by moving object

Solution Approach 1:

The system performs dataform decoding at periodic intervals rather than continuously, analyzing only specific frames (e.g., every nth frame) of the video stream. This periodic approach maintains scanning functionality while significantly reducing processor activation frequency and battery consumption compared to continuous decoding.

Inventive Principle:

Principle #19Periodic action

Solution Approach 2:

The decoding system dynamically adjusts its operation based on detected conditions, such as motion detection, frame complexity, or user preferences. When motion is detected or a dataform is likely present, decoding intensity increases; otherwise, it reduces processing activity, optimizing the balance between scanning capability and energy consumption.

Inventive Principle:

Principle #15Dynamics

2Adaptability or versatility

If dataform decoding is performed in existing computing devices, then scanning functionality is added, but processor intensity increases

Engineering Contradiction:

Improvescanning functionalityVSAvoidprocessor intensity

Core Design Contradiction:

Adaptability or versatilityVSPower

Solution Approach 1:

The video processing pipeline is segmented into multiple stages: initial video capture, preliminary frame analysis, dataform detection, and detailed decoding. Only frames that pass preliminary analysis and show potential dataform characteristics proceed to full decoding, dividing the processor-intensive task into manageable segments that reduce overall CPU load.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system performs partial decoding operations on all frames (light processing) and full decoding only on selected frames where dataforms are detected. This partial action approach ensures scanning coverage while avoiding the excessive processor intensity of complete decoding on every frame.

Inventive Principle:

Principle #16Partial or excessive action

3Productivity

If video processing modules are applied in parallel, then processing efficiency improves, but device complexity increases

Engineering Contradiction:

Improveprocessing efficiencyVSAvoidsystem architecture

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The parallel processing system is segmented into independent video processing modules, each handling specific tasks (e.g., frame extraction, motion detection, dataform recognition). This modular segmentation enables parallel execution while maintaining manageable complexity through clear module boundaries and standardized interfaces.

Inventive Principle:

Principle #1Segmentation
