Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If traditional development platforms and interfaces are used for safety relay programming, then comprehensive configuration capabilities are achieved, but the programming complexity increases and becomes difficult to interpret

Engineering Contradiction:
Improveprogramming easeVSAvoidconfiguration complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The configuration process is divided into sequential steps (e.g., step 302, 304, 306, 308) that guide users through configuration in manageable portions. Each step presents only the necessary parameters for that specific stage, preventing users from being overwhelmed by the entire configuration scope at once.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system performs preliminary organization of configuration parameters and presents them in a predetermined sequence. Default values and pre-configured options are provided in advance, allowing users to proceed without having to plan or understand the entire configuration structure beforehand.

Inventive Principle:
Principle #10Preliminary action

2Adaptability or versatility

If comprehensive configuration options are provided for safety relay terminals, then system versatility is improved, but the interface becomes more difficult to navigate and interpret

Engineering Contradiction:
Improveconfiguration flexibilityVSAvoidinterface usability
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The interface dynamically adapts to user progress through the configuration steps. Parameters and options are displayed contextually based on the current step, and the interface updates automatically as users proceed, providing relevant information only when needed rather than presenting all options simultaneously.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The configuration interface adds a temporal dimension to parameter presentation by organizing options sequentially across multiple steps. This transforms the static, overwhelming display of all parameters into a dynamic, time-based progression where users encounter parameters in a logical sequence, reducing cognitive load.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Loss of information

If detailed configuration parameters are displayed simultaneously, then complete information availability is achieved, but user comprehension and interpretation become difficult

Engineering Contradiction:
Improveinformation completenessVSAvoidparameter interpretability
Core Design Contradiction:
Loss of informationVSDifficulty of detecting and measuring

Solution Approach 1:

Configuration parameters are segmented and presented in discrete steps rather than displayed all at once. Each step focuses on a specific aspect of the configuration (e.g., basic settings, advanced parameters, validation), allowing users to comprehend and interpret parameters in context without being overwhelmed by the complete set of options.

Inventive Principle:
Principle #1Segmentation
