Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If manual customization process involving multiple professionals is used, then comprehensive design and manufacturing expertise is achieved, but the process becomes cumbersome and time-consuming

Engineering Contradiction:

Improvedesign qualityVSAvoidcustomization time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The system enables self-service automation where the computer automatically coordinates between design constraints, manufacturing feasibility, and ergonomic requirements without human intervention. The automated processing evaluates multiple parameters and generates customized frame proposals independently, eliminating the need for manual coordination between multiple professionals while maintaining comprehensive quality standards.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent replaces the mechanical system of manual professional coordination with an automated computer-based information processing system. The computer automatically performs tasks that previously required human professionals to evaluate constraints, calculate ergonomics, and coordinate manufacturing parameters, thereby dramatically reducing customization time while preserving design reliability.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Adaptability or versatility

If extensive customization modifications are made to meet user preferences, then user satisfaction is improved, but technical feasibility and ergonomics may be compromised

Engineering Contradiction:

Improvecustomization flexibilityVSAvoidergonomic compliance

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The system implements automated feedback loops where the computer continuously evaluates customization proposals against ergonomic constraints and manufacturing feasibility. When user preferences conflict with technical requirements, the system automatically adjusts parameters to maintain ergonomic compliance while maximizing user satisfaction, ensuring that customized frames remain wearable and functional.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The patent utilizes automated parameter optimization where the computer dynamically adjusts frame geometry, material properties, and manufacturing parameters to balance user preferences with ergonomic requirements. By automatically modifying technical parameters within feasible ranges, the system maintains ergonomic compliance while achieving extensive customization flexibility.

Inventive Principle:

Principle #35Parameter changes

3Productivity

If automated processing is implemented for instant customization, then productivity is improved, but device complexity increases

Engineering Contradiction:

Improvecustomization speedVSAvoidsystem complexity

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The patent employs a universal computer-based system that performs multiple functions including constraint evaluation, ergonomic calculation, manufacturing feasibility assessment, and automated design generation. This multi-functional approach consolidates what would otherwise require multiple separate specialized systems, achieving high productivity while managing complexity through integration rather than multiplication of components.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

Providing an eyeglasses frame in a fully automatized manner includes: (d) obtaining a set of data relating to a 3D representation of the frame, from: (a) initial information relating to an initial representation of the frame; and (b) at least one wearer parameter, possibly automatically modified; and (c) at least one frame parameter, possibly automatically modified; and taking account of at least one constraint or automatically modified constraint, relating to geometry of the frame; and automatically providing the 3D representation from the obtained set of data; (e) applying an evaluation criterion to determine whether the 3D representation satisfies the constraint or automatically modified constraint and, if not, (f) iterating obtaining (d) and applying (e) with the automatically modified wearer parameter and/or with the automatically modified frame parameter and/or with the automatically modified constraint, to automatically provide a constraint-compliant set of data relating to a final representation of the frame.
