Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a hybrid broadcasting/communication system is implemented, then system functionality and adaptability are improved, but component selection complexity at the reception side increases

Engineering Contradiction:
Improvesystem functionalityVSAvoidcomponent selection complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system segments media content into atomic components that can be independently selected and assembled. The component structure table divides the media stream into discrete, manageable units with specific attributes, allowing the reception device to selectively assemble components based on capabilities and preferences without being overwhelmed by the entire system complexity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces a new dimensional approach by creating a multi-layered component selection model (adaptive layer, composite layer, selective layer) that adds structural organization to the selection process. This dimensional framework transforms the complex selection problem into a hierarchical decision-making process across multiple levels.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Ease of operation

If component selection flexibility is increased, then user preference accommodation is improved, but system complexity increases

Engineering Contradiction:
Improvecomponent selection flexibilityVSAvoidsystem complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

By segmenting the media stream into atomic components with well-defined attributes, the system enables flexible component selection while maintaining manageable complexity. Each component can be independently evaluated and selected based on user preferences and device capabilities, avoiding the need to manage complex interdependencies.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system implements dynamic component selection through adaptive layers that can adjust component assembly based on real-time device capabilities, network conditions, and user preferences. This dynamic approach allows the system to adapt to different scenarios without requiring a completely different selection mechanism for each case.

Inventive Principle:
Principle #15Dynamics

3Measurement precision

If atomic components are defined with detailed attributes, then component selection precision is improved, but information processing load increases

Engineering Contradiction:
Improvecomponent selection precisionVSAvoidinformation processing load
Core Design Contradiction:
Measurement precisionVSUse of energy by moving object

Solution Approach 1:

The component structure table segments media information into atomic components with essential attributes, providing sufficient precision for selection while avoiding unnecessary detailed processing. Each component contains only the critical attributes needed for selection and assembly, reducing the overall information processing load compared to analyzing entire media streams.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system applies partial action by processing and analyzing only the essential attributes of atomic components rather than complete media content. This selective processing approach provides sufficient precision for component selection while significantly reducing the information processing load compared to comprehensive analysis.

Inventive Principle:
Principle #16Partial or excessive action
