Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing optical discs lack the ability for consumers to easily store and identify data, relying on commercial machines for data burning and manual labeling, which is inefficient and limited in functionality.

Innovation Solution

A color former phase comprising a color former, radiation absorber, and acrylic resin, forming an amorphous solid, is used to create a radiation image-able substrate that allows for data storage and graphic displays on optical discs, enabling users to store and identify data using electromagnetic radiation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If commercial machines are used for data burning and screen printing for labeling, then data storage and identification functionality is achieved, but device complexity and manufacturing cost increase

Engineering Contradiction:

Improvedata storage and identification functionalityVSAvoiddevice complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent combines data storage and identification functions into a single integrated layer on the optical disc. The color former composition is applied to the same layer where data is stored, eliminating the need for separate commercial labeling machines and integrating multiple functions into one system.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The optical disc structure is designed to perform multiple functions: data storage through the reflective layer and identification through the color former composition. The same disc structure and manufacturing process enable both data recording and visual identification, making the disc universal for both purposes without requiring additional equipment.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If manual labeling is used for disc identification, then identification functionality is achieved, but productivity and efficiency decrease

Engineering Contradiction:

Improveidentification functionalityVSAvoidproductivity

Core Design Contradiction:

Adaptability or versatilityVSProductivity

Solution Approach 1:

The color former composition enables the disc to identify itself automatically through color changes visible to the user. The composition responds to laser exposure during manufacturing to create visible identifiers without requiring manual intervention, allowing the disc to provide its own identification function.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent replaces manual mechanical labeling processes with an automated optical-chemical system. The color former composition undergoes chemical changes when exposed to laser radiation during manufacturing, automatically creating identification marks without manual writing or screen printing processes.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Quantity of substance

If conventional data storage methods are used, then data storage capability is achieved, but ease of operation and user convenience decrease

Engineering Contradiction:

Improvedata storage capabilityVSAvoiduser convenience

Core Design Contradiction:

Quantity of substanceVSEase of operation

Solution Approach 1:

The color former composition changes color in response to laser exposure, providing visual feedback to users about data storage status. Different colors indicate different states (e.g., written vs. unwritten sectors), making the disc easier to operate and monitor without requiring specialized reading equipment.

Inventive Principle:

Principle #32Color changes

Solution Approach 2:

The color former provides immediate visual feedback to users during the data writing process. As the laser writes data to the disc, the color former changes color to indicate which areas have been written, giving users real-time feedback about the storage process and disc status.

Inventive Principle:

Principle #23Feedback
