Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a generic detection model is deployed on IoT devices, then device compatibility is improved, but detection performance deteriorates

Engineering Contradiction:
Improvedevice compatibilityVSAvoiddetection performance
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The patent segments IoT devices into different clusters based on their capability parameters (processing power, memory, sensors). Each cluster receives a tailored detection model optimized for its specific capabilities, rather than using a single generic model for all devices. This segmentation allows the system to maintain high detection performance for each device type while ensuring broad compatibility across the IoT ecosystem.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent applies local quality by customizing detection models for specific device clusters rather than using a uniform approach. Each cluster's detection model is locally optimized based on the specific capability parameters of devices in that cluster, ensuring that each device receives a model with appropriate complexity and resource requirements for its hardware characteristics.

Inventive Principle:
Principle #3Local quality

2Reliability

If a detection model is optimized for specific device capabilities, then detection performance is improved, but device complexity increases

Engineering Contradiction:
Improvedetection performanceVSAvoidmodel deployment complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent implements a dynamic model deployment system where detection models are automatically selected and configured based on real-time assessment of device capability parameters. The system dynamically clusters devices and assigns appropriate models without requiring manual intervention, reducing deployment complexity while maintaining optimized performance for each device type.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system enables self-service by allowing IoT devices to automatically report their capability parameters and receive appropriately configured detection models without manual configuration. The automated clustering and model assignment process eliminates the need for complex manual deployment procedures, reducing the perceived complexity for end users while maintaining high detection performance.

Inventive Principle:
Principle #25Self-service

3Reliability

If detection models are customized for each device, then detection performance is improved, but resource consumption increases

Engineering Contradiction:
Improvedetection performanceVSAvoidcomputational resources
Core Design Contradiction:
ReliabilityVSUse of energy by moving object

Solution Approach 1:

The patent changes key parameters such as model size, complexity, and architecture based on the capability parameters of each device cluster. By adjusting these parameters according to device resources (processing power, memory, battery capacity), the system achieves optimized detection performance while preventing excessive resource consumption. Devices with limited resources receive lighter models, while more powerful devices can handle more complex models.

Inventive Principle:
Principle #35Parameter changes
