Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If multiple streams are transmitted separately over wireline-wireless connections, then each stream can be managed independently, but bandwidth utilization is inefficient and interference increases

Engineering Contradiction:

Improvebandwidth utilizationVSAvoidinterference

Core Design Contradiction:

ProductivityVSObject-affected harmful factors

Solution Approach 1:

The patent combines multiple independent data streams into a single multiplexed stream for transmission over the wireline-wireless connection. This merging approach improves bandwidth utilization by efficiently packing multiple streams into available capacity while reducing the number of separate transmissions that cause interference. The multiplexing is achieved through packetization and interleaving techniques that integrate multiple streams into a unified transmission channel.

Inventive Principle:

Principle #5Merging (Combining)

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The patent segments data into packets with specific structures including headers and payloads, allowing for systematic multiplexing and management of multiple streams. This segmentation enables efficient bandwidth utilization and quality of service management while maintaining manageable system complexity through standardized packet formats and processing procedures.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent introduces a multiplexing layer as an intermediary between the data source and the wireline-wireless transmission medium. This intermediary performs packetization, multiplexing, and interleaving operations that improve data rate and quality of service while isolating the complexity of these operations from both the data sources and the transmission medium, making the overall system more manageable.

Inventive Principle:

Solution Approach 1:

The patent employs interleaving techniques that periodically distribute data from multiple streams across transmission time slots. This periodic structure allows the system to adapt to varying channel conditions by spreading data transmission over time, reducing the impact of signal degradation and interference while maintaining extended coverage capability.
