Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If connected devices are pre-configured to automatically connect to a given pre-defined network, then connection establishment is simplified and automatic, but the device is limited to communicate with only that given network and cannot switch to other networks

Engineering Contradiction:
Improveautomatic connection establishmentVSAvoidnetwork switching capability
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The patent introduces a cloud switch server as an intermediary between connected devices and multiple cloud networks. The cloud switch server receives switching requests from connected devices, evaluates multiple available clouds based on specified criteria (security, cost, latency, SLA), and directs the device to the most suitable cloud. This intermediary enables automatic connection management while providing adaptability across multiple networks, resolving the contradiction between ease of operation and adaptability.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If connected devices are locked to a given pre-defined network, then configuration is simple and secure, but the device depends on the availability of that single network and cannot optimize based on different network characteristics

Engineering Contradiction:
Improveconnection availabilityVSAvoidnetwork optimization capability
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent implements dynamic network selection by continuously monitoring multiple cloud networks and their characteristics (security level, cost, communication latency, SLA). The cloud switch server dynamically evaluates available clouds against device requirements and switching criteria, enabling the device to adaptively switch between networks based on real-time conditions. This dynamic approach maintains reliability through multiple backup options while providing optimization capability based on current network states.

Inventive Principle:
Principle #15Dynamics

3Adaptability or versatility

If connected devices can connect to multiple networks with different characteristics, then adaptability and optimization are improved, but the complexity of managing connections and authentication increases

Engineering Contradiction:
Improvemulti-network connection capabilityVSAvoidconnection management complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The cloud switch server acts as a centralized management intermediary that handles all complexity associated with multi-network connections. It maintains authentication credentials, manages connection states, evaluates multiple clouds based on criteria, and handles switching logic. The connected device itself remains simple, issuing only high-level switching requests without needing to understand or manage the underlying complexity of multiple network connections, authentication mechanisms, or evaluation criteria.

Inventive Principle:
Principle #24Intermediary (Mediator)

4Adaptability or versatility

If manual configuration is used for each network connection, then connection control is precise, but seamless configuration and automatic switching between networks is impossible

Engineering Contradiction:
Improvenetwork switching flexibilityVSAvoidconfiguration automation
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The system implements automatic network switching through feedback mechanisms. The cloud switch server continuously monitors network characteristics (security, cost, latency, SLA) and device operational status, compares current performance against switching criteria and device requirements, and automatically initiates cloud switching when optimization opportunities are detected. This closed-loop feedback system enables seamless configuration and automatic switching without manual intervention, while maintaining precise control over switching decisions based on evaluated criteria.

Inventive Principle:
Principle #23Feedback
