Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If content is shared in a distributed storage environment with multiple candidate devices, then content availability and sharing flexibility are improved, but selecting an optimal source device becomes complex due to varying channel quality, hardware performance, and resource availability

Engineering Contradiction:

Improvecontent sharing flexibilityVSAvoidsource device selection complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent introduces a central management device as an intermediary that collects channel quality information, hardware performance data, and resource availability from multiple candidate devices. This mediator consolidates the complex selection criteria and provides structured information to the request device, simplifying the source device selection process while maintaining the benefits of distributed storage flexibility

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The system performs preliminary actions by having candidate devices pre-report their channel quality, hardware performance, and resource availability to the central management device before actual content sharing occurs. This advance preparation creates a ready-to-use information base that speeds up the source device selection process and reduces real-time decision complexity

Inventive Principle:

Principle #10Preliminary action

2Adaptability or versatility

If multiple transmission paths are available between request device and source device, then routing flexibility is improved, but determining the optimal transmission path becomes difficult due to varying channel qualities

Engineering Contradiction:

Improvetransmission path flexibilityVSAvoidoptimal path detection difficulty

Core Design Contradiction:

Adaptability or versatilityVSDifficulty of detecting and measuring

Solution Approach 1:

The patent implements feedback mechanisms where channel quality information is continuously collected and reported to the central management device. This feedback loop enables the system to monitor transmission path qualities and dynamically adjust path selection, making it easier to identify optimal paths while maintaining routing flexibility

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The central management device acts as an intermediary that collects and processes channel quality information for multiple transmission paths. By consolidating this information centrally, the system simplifies the complexity of evaluating multiple paths with varying qualities, enabling more efficient path selection

Inventive Principle:

Principle #24Intermediary (Mediator)

3Productivity

If source device selection considers multiple factors including channel quality, hardware performance, and resource availability, then content sharing optimization is improved, but measurement and information collection overhead increases

Engineering Contradiction:

Improvecontent sharing efficiencyVSAvoidinformation collection overhead

Core Design Contradiction:

ProductivityVSLoss of time

Solution Approach 1:

The system performs preliminary information collection where candidate devices report their hardware performance and resource availability to the central management device in advance. This pre-collection of data reduces the time and overhead required during actual content sharing operations, as the selection criteria are already gathered and organized

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The central management device performs multiple functions including collecting channel quality information, gathering hardware performance data, monitoring resource availability, and facilitating source device selection. By consolidating these diverse functions into a single multi-functional entity, the system reduces overall measurement and information collection overhead compared to having separate mechanisms for each function

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A method for determining a source and a transmission path to provide content includes receiving a message comprising at least one of channel information of a link between a request device which requests content download and a central management device, available resource amount information of a candidate device, channel information of a link between the candidate device and the central management device, and channel information of a link between the request device and one candidate device. The method also includes determining a source device and the transmission path for providing the content to the request device using an available resource amount of the candidate device, a data rate of the link between the request device and the central management device, a data rate of the link between the request device and the candidate device, and a data rate of the link between the candidate device and the central management device.
