Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If manual configuration of machine learning models is used to process IoT sensor data, then the system can handle complex data processing requirements, but the training time becomes very long (weeks)

Engineering Contradiction:
Improvedata processing qualityVSAvoidtraining time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The LwM2M server automatically categorizes sensor parameters by controllability without human intervention. The server analyzes parameter identifiers, determines whether each parameter is controllable or uncontrollable, and annotates the data accordingly, enabling the machine learning model to self-configure and train rapidly without manual setup

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system performs preliminary categorization of parameters before the machine learning training process begins. By pre-annotating each sensor parameter with its controllability status using LwM2M resource identifiers and annotations, the system prepares the data structure in advance, eliminating the need for time-consuming manual configuration during model training

Inventive Principle:
Principle #10Preliminary action

2Measurement precision

If comprehensive sensor data from multiple IoT devices is collected to improve model accuracy, then the quality of machine learning output improves, but the complexity of data management and processing increases

Engineering Contradiction:
Improvemodel accuracyVSAvoiddata management complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The system segments the vast IoT sensor data into manageable categories based on controllability. Each parameter is individually identified, categorized as controllable or uncontrollable, and annotated separately. This segmentation allows the machine learning model to process different types of parameters systematically, reducing the complexity of managing comprehensive sensor data from multiple devices

Inventive Principle:
Principle #1Segmentation

3Reliability

If traditional simulation platforms are used to train machine learning models, then the models can be trained with detailed 3D environmental data, but the setup time becomes very long (1-2 weeks) and scalability is poor

Engineering Contradiction:

Core Design Contradiction:

Solution Approach 1:

The system replaces the mechanical 3D simulation platform approach with a data-driven LwM2M protocol-based system. Instead of using complex simulation environments that require detailed 3D models and lengthy setup, the invention uses standardized LwM2M resource identifiers and automated categorization to directly train machine learning models on real IoT sensor data, achieving both accuracy and speed

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

4Adaptability or versatility

If machine learning models are trained without automatic parameter categorization, then the models can process all sensor data uniformly, but the distinction between controllable and uncontrollable parameters is lost, requiring careful manual design

Engineering Contradiction:
Improvemodel flexibilityVSAvoidconfiguration complexity
Core Design Contradiction:

Solution Approach 1:

The LwM2M server performs self-service by automatically analyzing parameter identifiers, determining controllability status, and annotating data without human intervention. This automation maintains model flexibility while eliminating the need for careful manual design and configuration of parameter categories

Inventive Principle:
Principle #25Self-service
