Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a central data processing unit is used to process sensor data, then the system can be simplified and easier to manage, but the system becomes vulnerable to disruptions and single points of failure

Engineering Contradiction:
Improvecentralized controlVSAvoidsystem vulnerability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent divides the centralized data processing function into distributed network nodes. Each node independently processes sensor data and communicates with other nodes, eliminating the single point of failure. The system segments the control architecture into autonomous units that can operate independently while maintaining coordinated functionality through peer-to-peer communication.

Inventive Principle:
Principle #1Segmentation

2Reliability

If decentralized processing is implemented across multiple network nodes, then system reliability and security are improved, but the device complexity increases

Engineering Contradiction:
Improvesystem robustnessVSAvoidnetwork node architecture
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent implements universal node designs where each network node can perform multiple functions: sensing, data processing, communication, and coordination. This multi-functionality reduces the need for specialized components at each node, simplifying the overall architecture while maintaining decentralized processing benefits. Each node is designed as a self-sufficient unit that can operate independently or in coordination with others.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Ease of manufacture

If existing power and network infrastructure is relied upon, then the sensor system can be easily deployed, but the system loses flexibility and independence in complex environments

Engineering Contradiction:
Improvedeployment simplicityVSAvoidenvironmental flexibility
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The patent enables network nodes to be self-sufficient by integrating power generation capabilities (such as energy harvesting from environmental sources) and autonomous operation. Each node can generate its own power, process its own data, and communicate independently, eliminating dependence on external infrastructure. This self-service capability allows deployment in remote or complex environments where traditional power and network infrastructure is unavailable.

Inventive Principle:
Principle #25Self-service
