Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing eyeglasses frames made of cellulose acetate cannot achieve a superimposed double-color gradation effect or multiple color gradations in non-coinciding directions using conventional techniques.

Innovation Solution

A frame comprising at least two acetate sheets with color gradations, where one sheet has a gradated color and transparency, and the other sheet also has a gradation, coupled together through superimposition via adhesive bonding or other techniques to create a unique, pleasing aesthetic effect with infinite tonalities and orientations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If conventional coloring techniques are used on cellulose acetate, then single color gradation can be achieved, but superimposed double-color gradation or multiple color gradations in non-coinciding directions cannot be obtained

Engineering Contradiction:

Improvecolor gradation capabilityVSAvoidcolor application process

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The frame is divided into multiple acetate sheets, each with its own color gradation pattern. These segmented sheets are then superimposed to create the final multi-color gradation effect, allowing independent design of each sheet's coloring

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The solution transitions from applying color in a single dimension (conventional surface coloring) to multiple dimensions by stacking acetate sheets with different color gradations at different layers, creating superimposed color effects in the vertical dimension

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

2Adaptability or versatility

If multiple acetate sheets with color gradations are superimposed, then unique aesthetic effects with infinite tonalities and directions are achieved, but manufacturing complexity increases

Engineering Contradiction:

Improveaesthetic effect varietyVSAvoidframe assembly process

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The frame construction is segmented into multiple acetate sheets that can be independently manufactured with different color gradations, then assembled through superimposition to create unique aesthetic effects

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The frame utilizes composite construction by combining multiple acetate sheets with different optical properties (transparency, opacity, color gradation) to create a composite material structure with enhanced aesthetic versatility

Inventive Principle:

Principle #40Composite materials
