Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a main system interface uses a lower transmission rate to communicate with low-speed work stations, then communication compatibility is improved, but communication time increases and network efficiency deteriorates

Engineering Contradiction:

Improvecommunication compatibilityVSAvoidcommunication time

Core Design Contradiction:

Adaptability or versatilityVSLoss of time

Solution Approach 1:

The patent implements dynamic transmission rate adjustment by monitoring packet receipt status and adapting the transmission rate in real-time. The system transitions from static rate selection to dynamic rate adaptation, where the transmission rate is continuously adjusted based on the receiving device's buffer status and packet acknowledgment patterns, thereby reducing communication time while maintaining compatibility.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system employs feedback mechanisms by examining packet receipt status information from remote devices and using this information to evaluate packet receipt characteristics. This feedback loop enables the main system interface to adjust transmission parameters based on actual receiving conditions, optimizing communication efficiency without sacrificing compatibility.

Inventive Principle:

Principle #23Feedback

2Productivity

If the main system interface maintains high transmission rates, then network productivity is improved, but communication reliability with low-speed devices deteriorates

Engineering Contradiction:

Improvenetwork efficiencyVSAvoidcommunication reliability

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The system dynamically adjusts transmission rates based on real-time evaluation of packet receipt characteristics. Rather than maintaining a fixed high transmission rate, the system adapts its rate to match the receiving device's capabilities, ensuring reliable communication while maximizing network productivity through optimized rate selection.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent changes transmission parameters (rate, timing) based on evaluated packet receipt characteristics. By monitoring and responding to changes in packet acknowledgment patterns and buffer status, the system adjusts transmission parameters to maintain reliability across devices with varying speeds while preserving overall network efficiency.

Inventive Principle:

Principle #35Parameter changes

3Speed

If transmission rate is increased for high-speed devices, then data transfer speed is improved, but network congestion increases due to buffer overflow in low-speed devices

Engineering Contradiction:

Improvedata transfer speedVSAvoidnetwork congestion

Core Design Contradiction:

SpeedVSObject-generated harmful factors

Solution Approach 1:

The system uses feedback from packet receipt status information to detect buffer congestion conditions. By examining acknowledgment patterns and receipt characteristics, the system identifies when low-speed devices are experiencing buffer overflow and adjusts transmission rates accordingly, preventing network congestion while maintaining high data transfer speeds where possible.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The patent applies different transmission qualities (rates) to different receiving devices based on their individual characteristics. Rather than using a uniform transmission rate, the system tailors the transmission rate to each device's buffer capacity and processing speed, allowing high-speed devices to receive data at higher rates while protecting low-speed devices from congestion.

Inventive Principle:

AI summary

A communication device may include a transmitting circuit for transmitting packets from a first communication device to a second communication device and a processor in the first communication device and coupled with the transmitting circuit. The processor may evaluate the packet receipt status information to identify a packet receipt characteristic associated with the second communication device and control data packet transmission from the first communication device to the second communication device based on the packet receipt characteristic associated with the second communication device.
