Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If 2/3/4G mobile communication technology is used for MTC, then existing communication infrastructure can be utilized, but system complexity and power consumption increase significantly

Engineering Contradiction:

Improvecompatibility with existing infrastructureVSAvoidsystem complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent segments MTC devices into different groups based on their communication requirements and resource needs. By dividing the large-scale MTC device population into smaller manageable groups, the system reduces overall complexity while maintaining infrastructure compatibility. Each group can be managed with simplified procedures rather than treating all devices uniformly.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent implements preliminary actions by pre-configuring access resources and establishing registration procedures before MTC devices need to communicate. Base stations pre-allocate resources and devices perform preliminary registration, which simplifies subsequent communication operations and reduces real-time processing complexity.

Inventive Principle:

Principle #10Preliminary action

2Adaptability or versatility

If 2/3/4G mobile communication technology is used for MTC, then existing communication infrastructure can be utilized, but power consumption increases significantly

Engineering Contradiction:

Improvecompatibility with existing infrastructureVSAvoidpower consumption

Core Design Contradiction:

Adaptability or versatilityVSUse of energy by moving object

Solution Approach 1:

The patent implements periodic action through scheduled polling instructions and periodic registration opportunities. Instead of continuous communication operations, MTC devices wake up at predetermined intervals to receive polling instructions and perform registrations only when needed. This periodic operation pattern dramatically reduces power consumption compared to continuous operation in 2/3/4G systems.

Inventive Principle:

Principle #19Periodic action

Solution Approach 2:

MTC devices autonomously monitor for polling instructions and self-manage their registration processes without requiring continuous network control signaling. The devices can independently determine when to wake up, what resources to use, and how to complete registration, reducing the energy overhead associated with network-controlled operations.

Inventive Principle:

Principle #25Self-service

3Productivity

If machine communication devices are grouped for resource sharing, then resource utilization improves, but system deployment flexibility decreases

Engineering Contradiction:

Improveresource utilization efficiencyVSAvoidsystem deployment flexibility

Core Design Contradiction:

ProductivityVSAdaptability or versatility

Solution Approach 1:

The patent implements dynamic grouping where MTC device groups are not fixed but can be reconfigured based on current network conditions, device requirements, and resource availability. Base stations can dynamically adjust group compositions and resource allocations, maintaining both high resource utilization and deployment flexibility. The grouping structure adapts to changing conditions rather than being static.

Inventive Principle:

Principle #15Dynamics

4Productivity

If machine communication devices are grouped for resource sharing, then resource utilization improves, but battery life reduction rate increases

Engineering Contradiction:

Improveresource utilization efficiencyVSAvoidbattery life

Core Design Contradiction:

ProductivityVSDuration of action of moving object

Solution Approach 1:

The patent uses periodic polling instructions to notify MTC devices of resource sharing opportunities only when necessary. Devices remain in low-power states between polling intervals and only activate to share resources when explicitly instructed. This periodic resource sharing approach maintains high resource utilization efficiency while minimizing the frequency of device activations, thereby extending battery life.

Inventive Principle:

Principle #19Periodic action
