Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If user operations on smartphone are used to establish connections between IoT devices, then connection establishment is possible, but operation complexity increases and user operations become cumbersome

Engineering Contradiction:
Improveease of connection establishmentVSAvoidconnection complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

IoT devices automatically perform connection establishment by exchanging description information and autonomously determining device combinations without requiring user operations on a smartphone. The devices self-organize into combinations based on their own capabilities and requirements, eliminating the need for manual intervention.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

Description information acts as an intermediary carrier that enables automated connection establishment. This information package contains application scenario identifiers and performance information that mediate the interaction between devices, allowing them to autonomously determine compatibility and form connections without direct user control.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Adaptability or versatility

If quantity of IoT devices increases, then system functionality improves, but connection complexity increases

Engineering Contradiction:
Improvesystem functionalityVSAvoidconnection complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system segments the overall connection management into autonomous device-level decisions. Each device independently evaluates its own description information against received information from other devices, breaking down the complex global connection problem into simpler local decision-making units that can be handled independently.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Devices exchange parameterized description information including application scenario identifiers and performance metrics. These standardized parameters enable automated comparison and matching, allowing the system to scale to many devices while maintaining manageable complexity through structured data exchange.

Inventive Principle:
Principle #35Parameter changes

3Ease of operation

If automated connection establishment is implemented, then user operations are simplified, but device intelligence requirements increase

Engineering Contradiction:
Improveuser operation simplicityVSAvoiddevice autonomy
Core Design Contradiction:
Ease of operationVSExtent of automation

Solution Approach 1:

Devices autonomously perform connection establishment by processing their own description information and making independent decisions about which devices to connect with. The system transfers intelligence from the user to the devices themselves, which self-manage their connectivity based on predefined criteria.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

Devices provide feedback through exchanged description information about their capabilities and requirements. This feedback mechanism enables automated decision-making where devices respond to each other's characteristics, allowing intelligent connection establishment without user intervention.

Inventive Principle:
Principle #23Feedback
