Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image transmission methods using electromagnetic waves can be uncomfortable for humans due to prolonged exposure and may cause noise, and they are not suitable for scenarios requiring aesthetic or intuitive data transfer.
Innovation Solution
Converting images into sets of feature data and composing music using preset rules to transmit the data through audible sound waves, allowing for intuitive image transmission and aesthetic music generation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If electromagnetic waves (Bluetooth, Wi-Fi, infrared) are used for image transmission, then data transmission can be achieved, but prolonged exposure causes discomfort and potential harm to humans
Solution Approach 1:
The patent replaces electromagnetic wave-based transmission systems with sound wave-based transmission systems. Specifically, it converts images into musical elements (pitch, duration, intensity) that can be transmitted through audible sound waves, thereby substituting the harmful electromagnetic field with a mechanical acoustic field that is more comfortable for human exposure
Solution Approach 2:
The patent changes the physical parameter of the transmission medium from electromagnetic waves to sound waves within the audible frequency range (20Hz-20kHz). By encoding image data into musical parameters such as pitch sequences, note durations, and intensity variations, the system achieves image transmission using a different physical domain that is more benign to human health
2Productivity
If ultrasound or infrasonic waves are used for data transmission, then data can be transmitted, but the sound may be perceived as harsh or rustling causing discomfort
Solution Approach 1:
The patent specifically constrains the sound wave frequency parameter to fall within the audible range (20Hz-20kHz) and encodes image data into musical elements that produce pleasant, aesthetically pleasing sounds. By mapping image features to pitch sequences and musical structures, the system ensures that the transmitted sound is perceived as music rather than harsh noise, thus maintaining productivity while eliminating the harmful auditory effect
3Object-affected harmful factors
If hearable sound waves are used for image transmission, then comfortable and intuitive transmission can be achieved, but transmission speed is limited
Solution Approach 1:
The patent acknowledges that sound wave transmission is suitable for scenarios not requiring high data speed. By applying partial action, the system optimizes the encoding process for aesthetic and comfortable transmission rather than maximum speed, accepting lower transmission rates in exchange for human comfort and intuitive experience in applications like entertainment, education, and advertising

AI summary
Embodiments of the present disclosure relate to a method and apparatus for transmitting an image. The method includes converting, by a first device, an image to be transmitted into a number of sets of feature data according to a preset conversion rule; performing, by the first device, music composition according to preset music composition rules to obtain a music in accordance with musical tone rules through making each set of the number of sets of feature data correspond to one musical element; and playing, by the first device, the music to a second device. An image transmission manner utilizing a sound wave that is hearable to the human ear may be implemented.
