Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional configuration tools are used for building controllers, then control functionality and reliability are improved, but device complexity and difficulty of operation increase

Engineering Contradiction:
Improvecontrol functionalityVSAvoidprogramming difficulty
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

A mobile device application serves as an intermediary between the user and the building controller configuration process. The application provides an intuitive graphical user interface that guides users through configuration steps, automatically generates control logic, and communicates with the building controller, thereby simplifying the programming process while maintaining reliable control functionality

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The system enables self-service configuration by allowing end-users to program building controllers themselves without requiring specialized training. The configuration tool automatically processes user inputs, generates appropriate control logic, and configures the controller, eliminating the need for professional programmers

Inventive Principle:
Principle #25Self-service

2Manufacturing precision

If specialized professionals are used for configuration, then programming precision and control logic quality are improved, but loss of time and operational efficiency worsen

Engineering Contradiction:
Improvecontrol logic qualityVSAvoidconfiguration time
Core Design Contradiction:
Manufacturing precisionVSLoss of time

Solution Approach 1:

The configuration tool performs preliminary actions by automatically generating control logic and configuration parameters based on user inputs. The system pre-configures standard control scenarios and provides template-based solutions that eliminate the need for manual programming, thereby maintaining high control logic quality while significantly reducing configuration time

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system empowers end-users to independently configure building controllers with professional-quality results. The automated configuration process maintains high precision by incorporating validation rules and best practices directly into the user interface, eliminating the need for specialized professionals while reducing configuration time

Inventive Principle:
Principle #25Self-service

3Adaptability or versatility

If comprehensive configuration options are provided, then adaptability and control capability are improved, but device complexity increases

Engineering Contradiction:
Improveequipment compatibilityVSAvoidconfiguration complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The configuration process is segmented into distinct, manageable steps presented through a structured workflow in the user interface. Users progress through sequential stages such as equipment selection, parameter configuration, and validation, with each step focusing on a specific aspect of configuration. This segmentation makes the system adaptable to various equipment types while keeping the user interface simple and manageable

Inventive Principle:
Principle #1Segmentation
