Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If abundant resource is allocated for communication at all times, then communication reliability is improved, but resource usage efficiency deteriorates

Engineering Contradiction:

Improvecommunication reliabilityVSAvoidresource usage efficiency

Core Design Contradiction:

ReliabilityVSLoss of energy

Solution Approach 1:

The patent implements dynamic channel switching where the communication device transitions between first channel (e.g., licensed spectrum) and second channel (e.g., unlicensed spectrum) based on real-time conditions including interference levels, temporal constraints, and network indications. This dynamic adaptation allows the system to maintain communication reliability by having fallback channels available while improving resource efficiency by actively using only the necessary channel resources at any given time.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system changes operational parameters by switching between different channel configurations based on detected conditions. When interference conditions worsen or temporal constraints change, the device modifies its communication parameters by transitioning to alternative channels, thereby maintaining reliability without permanently allocating abundant resources across all channels.

Inventive Principle:

Principle #35Parameter changes

2Device complexity

If single channel is used for communication, then device complexity is reduced, but adaptability to different conditions deteriorates

Engineering Contradiction:

Improvechannel management complexityVSAvoidchannel adaptability

Core Design Contradiction:

Device complexityVSAdaptability or versatility

Solution Approach 1:

The patent segments the communication spectrum into multiple distinct channels (first channel and second channel with different characteristics such as licensed vs. unlicensed spectrum). Each channel is managed with specific protocols and rules, allowing the device to adapt to different communication conditions by selecting appropriate segments while keeping individual channel management relatively simple.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The communication device is designed with multi-functional capability to operate on both first and second channels, making it universally adaptable to different communication scenarios. The device can perform the same communication functions across multiple channel types, enhancing versatility without proportionally increasing complexity through standardized multi-channel operation procedures.

Inventive Principle:

Principle #6Universality (Multi-functionality)
