Solution Overview

Problem

Existing eyewear may not be adequately adapted for specific activities or features beyond its original intent, such as outdoor or sports use, and lacks the ability to incorporate additional features like improved sun protection or electronic components.

Innovation Solution

A method to generate modified eyeglass frame manufacturing data based on an existing frame and a target activity or feature, using a processor to automate the customization of parameters like pantoscopic angle, temple shape, and base curve while preserving the frame's aesthetics and functionality.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If an existing eyeglass frame is modified to adapt it for specific activities (e.g., sports, outdoor use), then the adaptability and functionality for the target activity are improved, but the original aesthetic design and spirit of the frame may be compromised

Engineering Contradiction:
Improveadaptability for specific activityVSAvoidaesthetic design
Core Design Contradiction:
Adaptability or versatilityVSShape

Solution Approach 1:

The modification process is segmented into distinct steps: selecting the original frame, determining target activity requirements, modifying specific parameters (pantoscopic angle, face form angle, wrap angle, temple shape), and generating new manufacturing data. This segmentation allows selective modification of only necessary parameters while preserving the overall aesthetic design.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent applies local quality by modifying specific local parameters (angles, temple shape) rather than the entire frame structure. This enables targeted adaptations for specific activities while maintaining the global aesthetic characteristics of the original frame design.

Inventive Principle:
Principle #3Local quality

2Adaptability or versatility

If multiple parameters of the eyeglass frame are modified to suit specific activities, then the functionality for the target activity is improved, but the complexity of the modification process increases

Engineering Contradiction:
Improvefunctionality for target activityVSAvoidmodification process complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent creates a universal modification method that can adapt any existing eyeglass frame for multiple different activities (sports, outdoor use, driving, etc.). The systematic approach using standardized parameters and conception rules makes the process reusable across different frame types and activity requirements, reducing overall complexity.

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

Solution Approach 2:

The patent systematically changes specific geometric parameters (pantoscopic angle, face form angle, wrap angle, temple shape) based on activity requirements. This parameter-based approach provides a structured method for modification, making the process more manageable and less complex than redesigning the entire frame structure.

Inventive Principle:
Principle #35Parameter changes

3Reliability

If the eyeglass frame is customized for specific activities with modified parameters, then the performance for the intended activity is improved, but the manufacturing complexity and data processing requirements increase

Engineering Contradiction:
Improveperformance for intended activityVSAvoidmanufacturing data complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent performs preliminary actions by automatically determining and calculating all necessary modification parameters before manufacturing. The system pre-computes the modified pantoscopic angle, face form angle, wrap angle, and temple shape parameters, and prepares complete manufacturing data in advance, simplifying the actual manufacturing process.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent replaces manual measurement and modification processes with automated computational methods. The system uses processors to automatically calculate modified parameters and generate manufacturing data, substituting complex manual mechanical processes with automated digital computation.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)
