Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If point-to-point streaming is used to deliver content to mobile devices, then device compatibility and individual content selection are improved, but network bandwidth consumption and resource demand increase

Engineering Contradiction:

Improvedevice compatibilityVSAvoidnetwork bandwidth

Core Design Contradiction:

Adaptability or versatilityVSQuantity of substance

Solution Approach 1:

The patent segments the delivery mechanism into two parts: broadcast transmission for the actual content stream and point-to-point control channels for device-specific instructions. This allows the content to be efficiently distributed to multiple devices simultaneously via broadcast while maintaining individual device compatibility through targeted control messages.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent merges broadcast transmission (for efficient multi-device content delivery) with point-to-point control channels (for individual device compatibility and selection). This combination allows the system to leverage the bandwidth efficiency of broadcast while maintaining the adaptability of point-to-point communication for device-specific requirements.

Inventive Principle:

Principle #5Merging (Combining)

2Quantity of substance

If broadcast transmission is used to deliver content, then network bandwidth efficiency is improved, but device compatibility and individual content selection capability deteriorate

Engineering Contradiction:

Improvenetwork bandwidth efficiencyVSAvoidindividual content selection

Core Design Contradiction:

Quantity of substanceVSAdaptability or versatility

Solution Approach 1:

The patent introduces point-to-point control channels as intermediaries between the broadcast content and individual devices. These control channels carry device-specific instructions, content selection information, and compatibility parameters, enabling each device to independently select and process appropriate content from the broadcast stream based on its capabilities.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

Inventive Principle:

Principle #1Segmentation

3Reliability

If network bandwidth is increased to handle all streaming demands, then service quality is improved, but network cost and resource requirements worsen

Engineering Contradiction:

Core Design Contradiction:

ReliabilityVSQuantity of substance

Solution Approach 1:

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The patent implements dynamic switching between broadcast and point-to-point delivery modes based on real-time network conditions, content type, and device characteristics. This dynamic approach allows the system to optimize resource allocation by using broadcast when efficient and switching to point-to-point when individualized delivery is required.

Inventive Principle:

Principle #15Dynamics

4Productivity

If dynamic optimization and analysis of all data streams is implemented, then network resource allocation is improved, but system complexity and computational requirements worsen

Engineering Contradiction:

Improvenetwork resource allocation efficiencyVSAvoidsystem complexity

Core Design Contradiction:

Solution Approach 1:

The patent extracts the complex optimization and analysis functions from the network core and places them in distributed network elements and device-side components. This distribution of computational complexity allows the system to perform dynamic optimization without overburdening any single component, maintaining high productivity while managing system complexity through distributed intelligence.

Inventive Principle:
