Innovation Solution

Faster and more efficient methods and interfaces for providing auditory features, reducing the number of inputs required and conserving power by using improved visual feedback and conditional operations without additional user input.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If video content is displayed on a screen, then visual information is transmitted to users, but users with visual impairments cannot access this information

Engineering Contradiction:
ImproveAccessibility to visual informationVSAvoidVisual impairment limitation
Core Design Contradiction:
Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The patent introduces an intermediary system consisting of audio spectrum analysis software and audio output devices that convert visual video content into audible spectral representations. This intermediary translates the visual information into an alternative sensory modality, enabling users with visual impairments to access video content through sound frequency analysis and visualization.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent replaces the visual-mechanical display system with an auditory-based system. Instead of relying on visual perception of screen content, the system substitutes visual information with audio signals that represent the spectral composition of video content, allowing users to perceive visual information through hearing rather than sight.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Loss of information

If audio spectrum analysis software is used to analyze video content, then spectral information is extracted and made accessible, but the software requires significant processing resources

Engineering Contradiction:
ImproveRetention of spectral informationVSAvoidProcessing resource consumption
Core Design Contradiction:
Loss of informationVSUse of energy by moving object

Solution Approach 1:

The patent extracts only the essential spectral information from video content that is relevant to user perception, rather than processing and transmitting all visual data. By identifying and extracting key frequency components that represent the visual content's spectral characteristics, the system reduces processing requirements while maintaining information fidelity for users with visual impairments.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent transforms video content from the visual domain into the auditory domain by changing the representation parameters. Instead of processing visual pixels and colors, the system converts content into audio frequency spectra, utilizing different physical parameters (sound frequencies) to represent the same informational content, thereby reducing processing complexity.

Inventive Principle:
Principle #35Parameter changes

3Adaptability or versatility

If video content is converted to audio spectrum representation, then accessibility is improved for visually impaired users, but the original visual information is lost

Engineering Contradiction:
ImproveAccessibility for visually impaired usersVSAvoidLoss of visual content
Core Design Contradiction:
Adaptability or versatilityVSLoss of information

Solution Approach 1:

The patent creates an auditory copy or representation of visual video content rather than replacing the original. The audio spectrum analysis generates a parallel representation of the video's spectral characteristics that can be perceived through hearing, preserving the informational content in an alternative format without destroying the source material.

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The patent makes the video content accessible through multiple sensory channels by creating both visual and auditory representations. The system enables the same content to be accessed through different modalities (sight and sound), providing universal access for users with different sensory capabilities while maintaining the original visual format for those who can see.

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