Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If nerve impulses are converted into audio signals for sound perception enhancement, then auditory perception is improved, but device complexity increases due to the need for impulse-sound mapping and processing systems

Engineering Contradiction:
Improveauditory perception accuracyVSAvoidprocessing system complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent introduces a processing device as an intermediary between the auditory nerve and the brain. This device converts nerve impulses into audio signals through impulse-sound mapping, acting as a mediator that translates neural signals into perceptible sound. The processing device includes components for signal acquisition, conversion, and output, thereby resolving the contradiction by providing a structured intermediary system that enables accurate auditory perception while managing the inherent complexity through modular architecture.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Productivity

If audio signals are converted into nerve impulses for direct brain transmission, then sound transmission efficiency is improved, but reliability decreases due to potential signal loss or distortion in the conversion process

Engineering Contradiction:
Improvesound transmission efficiencyVSAvoidsignal transmission reliability
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The patent implements feedback mechanisms in the conversion process from audio signals to nerve impulses. The processing device monitors the converted signals and adjusts the conversion parameters to maintain signal integrity. This feedback loop ensures that the converted nerve impulses accurately represent the original audio signals, thereby maintaining reliability while achieving efficient sound transmission to the brain.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The patent employs error correction and signal protection mechanisms before the conversion process. By preparing and protecting the audio signals in advance through encoding and validation, the system cushions against potential signal loss or distortion during conversion. This preemptive approach ensures reliable signal transmission even when efficiency optimizations are applied.

Inventive Principle:
Principle #11Beforehand cushioning (Prior cushioning)

3Adaptability or versatility

If signal modification operations are performed on audio signals, then auditory experience augmentation is improved, but loss of information increases due to potential distortion or alteration of original sound characteristics

Engineering Contradiction:
Improveauditory experience customizationVSAvoidoriginal sound fidelity
Core Design Contradiction:
Adaptability or versatilityVSLoss of information

Solution Approach 1:

The patent implements dynamic signal modification where the processing device adjusts signal parameters in real-time based on user preferences and environmental conditions. The impulse-sound mapping is not static but adapts dynamically, allowing customization of auditory experiences while preserving essential sound characteristics. This dynamic approach enables versatility in auditory enhancement while minimizing information loss through adaptive rather than fixed modifications.

Inventive Principle:
Principle #15Dynamics

AI summary

A processing device is interfaced with an auditory region of the brain of a subject that is responsible for auditory perception. The processing device receives signals associated with nerve impulses that are transmitted to the auditory region of the brain of the subject in response to sound collected by an ear of the subject. The processing device processes the received signals and generates at least one audio signal that is representative of the auditory perception, by the subject, of the sound collected by the ear. In certain embodiments, the processing device processes at least one audio signal that is representative of at least one sound to convert the at least one audio signal to a sequence of nerve impulses, and selectively provides the sequence of nerve impulses to the auditory region of the brain of the subject such that the subject audially perceives the at least one sound.
