Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a wearer selects configuration parameters from a set of options, then the lens can be customized to meet specific needs, but compatibility issues may arise between lens material, design parameters, and selected frames

Engineering Contradiction:
Improvelens customizationVSAvoidparameter compatibility
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The system provides immediate visual feedback through simulated images showing the lens in the selected frame, allowing the wearer to see compatibility issues before finalizing the configuration. The simulation updates in real-time as parameters are changed, enabling proactive adjustment of incompatible settings.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system performs preliminary compatibility checks and displays simulated images of the lens in the selected frame before the wearer commits to the configuration. This advance visualization allows potential compatibility issues to be identified and resolved beforehand, preventing incompatible combinations from being finalized.

Inventive Principle:
Principle #10Preliminary action

2Adaptability or versatility

If the wearer goes through a detailed parameter selection process, then the lens can be highly personalized, but the selection process becomes time-consuming

Engineering Contradiction:
Improvelens personalizationVSAvoidparameter selection time
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The system creates a visual copy or simulation of the lens in the selected frame, allowing the wearer to evaluate the final appearance and compatibility without needing to physically try on multiple configurations. This virtual representation accelerates the decision-making process while maintaining high personalization.

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The system adds a visual dimension to the parameter selection process by displaying simulated images alongside the configuration options. This graphical interface allows wearers to assess compatibility and appearance simultaneously with parameter selection, reducing the time needed to evaluate different configurations.

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

3Adaptability or versatility

If the system offers multiple configuration options, then the wearer can find the optimal lens, but the complexity of the selection interface increases

Engineering Contradiction:
Improveconfiguration optionsVSAvoidinterface complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system merges the parameter selection interface with a visual simulation display, combining multiple functions into a single integrated view. The configuration parameters and their visual impact are presented together, reducing the need for separate evaluation steps and simplifying the overall interface.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The simulated image display serves multiple functions simultaneously: it shows lens appearance, frame compatibility, and provides visual feedback on parameter changes. This multi-functional element reduces the need for separate interface components, simplifying the overall system while handling multiple configuration aspects.

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