Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If wireless terminals perform complex processing to meet high-performance wireless transmission requirements, then transmission rate, delay, throughput and reliability are improved, but power consumption increases

Engineering Contradiction:

Improvetransmission rateVSAvoidpower consumption

Core Design Contradiction:

ProductivityVSUse of energy by moving object

Solution Approach 1:

The patent introduces multiple UE processing time parameters (first UE processing time, second UE processing time, third UE processing time) that can be selected based on UE capability and configuration. This allows the system to change the processing time parameter to match different UE performance levels, enabling power-saving mode for devices with limited processing capabilities while maintaining high performance for capable devices

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent makes the UE processing time dynamic by allowing network nodes to determine which processing time to apply based on real-time conditions including UE capability information, configuration information, and channel conditions. This dynamic adaptation enables the system to optimize between performance and power consumption based on current operational context

Inventive Principle:

Principle #15Dynamics

2Productivity

Engineering Contradiction:

ImprovethroughputVSAvoidprocessing complexity

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The patent provides multiple discrete processing time options (first, second, and third UE processing times) that correspond to different processing complexity levels. This parameterization allows terminals with varying hardware capabilities to select appropriate processing time without requiring complex adaptive algorithms, simplifying the device complexity management

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent segments the processing time into distinct categories (first UE processing time for high performance, second UE processing time for balanced performance, third UE processing time for power saving) based on UE capability. This segmentation allows devices to be designed for specific capability levels rather than requiring all devices to support the full range of processing complexities

Inventive Principle:

Principle #1Segmentation

3Use of energy by moving object

If extended processing times are used for power saving, then power consumption is reduced, but transmission delay increases

Engineering Contradiction:

Improvepower savingVSAvoidprocessing delay

Core Design Contradiction:

Use of energy by moving objectVSLoss of time

Solution Approach 1:

The patent introduces multiple processing time parameters that can be selected based on service requirements. For services where low latency is critical (e.g., real-time communication), the first UE processing time can be applied. For services where power saving is more important (e.g., background data transfer), the third UE processing time can be applied, thus optimizing the trade-off between delay and power consumption per service type

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent enables dynamic selection of processing time based on service type, channel conditions, and UE capability. The network node can adaptively choose which processing time to apply based on current operational context, allowing the system to minimize delay when needed while maximizing power saving when appropriate

Inventive Principle:

Principle #15Dynamics
