Solution Overview

Problem

Conventional eyewear is often mass-produced with a uniform shape and angle, failing to fit various facial shapes and sizes, leading to discomfort and inefficiency in production for both users and manufacturers, especially when prescription lenses are involved.

Innovation Solution

Eyewear with a nose support system that allows adjustable angles through a coupling portion with coupling shafts and an adjustment tip, enabling vertical and horizontal movement to fit different face shapes and secure the angle post-adjustment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If eyewear is mass-produced with a uniform shape and angle, then manufacturing cost and efficiency are improved, but fit and comfort for various facial shapes deteriorate

Engineering Contradiction:

Improvemanufacturing efficiencyVSAvoidfit for various facial shapes

Core Design Contradiction:

ProductivityVSAdaptability or versatility

Solution Approach 1:

The nose support angle is made adjustable through a hinge mechanism that allows the nose support arm to rotate relative to the frame, transforming a static uniform structure into a dynamic adjustable one that can adapt to different facial shapes while maintaining mass production benefits

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The angle parameter of the nose support is made changeable through the hinge mechanism, allowing users to adjust the angle according to their facial shape, thereby resolving the contradiction between uniform mass production and individualized fit

Inventive Principle:

Principle #35Parameter changes

2Device complexity

If eyewear is mass-produced with a uniform shape and angle, then manufacturing complexity is reduced, but user comfort and customization deteriorate

Engineering Contradiction:

Improvemanufacturing complexityVSAvoiduser comfort

Core Design Contradiction:

Device complexityVSEase of operation

Solution Approach 1:

The hinge mechanism introduces minimal complexity to the manufacturing process while enabling significant user comfort improvements through adjustable nose support angle, balancing device complexity with ease of operation

Inventive Principle:

Principle #15Dynamics

3Adaptability or versatility

If the nose support angle is made adjustable, then adaptability to various facial shapes is improved, but device complexity increases

Engineering Contradiction:

Improveadjustability to facial shapesVSAvoidstructure complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The nose support system is segmented into the frame, hinge mechanism, and nose support arm as separate components, allowing the adjustability function to be added through the hinge while keeping the overall structure relatively simple and manageable

Inventive Principle:

Principle #1Segmentation
