Solution Overview

Problem

Current optical devices for image and sound association are limited to projecting images without the capability to generate or associate specific sounds with graphic elements, such as lines, shapes, or colors, and do not account for the space and time dynamics of drawing or image creation.

Innovation Solution

A hardware and software system that acquires and processes images on a transparent glass surface, using a camera with LED lighting and a CMOS sensor, to convert the visual spectrum into an acoustic spectrum, allowing real-time sound generation based on RGB values, saturation, and brightness, enabling additive sound synthesis from the spatial and temporal variations of user-drawn images.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If conventional image projection devices are used, then images can be projected, but sound association capability is lacking

Engineering Contradiction:

Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent combines image projection and sound generation capabilities into a single integrated device. The projector includes both optical components for image projection and acoustic components for sound generation, allowing simultaneous projection of images and association of sounds with graphic elements, thereby resolving the contradiction between versatility and device complexity

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The device is designed to perform multiple functions: projecting images, generating sounds, and associating sounds with specific graphic elements. This multi-functional approach enables the single device to replace what would traditionally require separate projection and audio systems, enhancing adaptability while managing complexity through integration

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

Solution Approach 1:

The system transitions from static image projection to dynamic real-time processing. The device continuously captures drawing actions, processes spatial and temporal variations of user input, and generates corresponding sounds in real-time. This dynamic capability enables productivity in sound generation while the processing complexity is managed through dedicated software algorithms

Inventive Principle:
