Solution Overview

Problem

Not all purr frequency signals are suitable for therapeutic use in biomechanical stimulation, necessitating a device that can specifically record and reproduce cat purr frequencies as vibrations for human and veterinary medicine.

Innovation Solution

A therapy device equipped with a structure-borne noise microphone to record cat purr frequencies, a filter to limit the bandwidth to 0-700 Hz, and a sound transducer using a permanent magnet and electrical coil to convert these signals into vibrations, embedded in a non-absorptive material for optimal transmission.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a sound transducer is used to reproduce purr frequency signals, then therapeutic vibrations can be transmitted to the human or animal body, but not all purr frequency signals are suitable for therapy use

Engineering Contradiction:
Improvetherapeutic effectivenessVSAvoidsignal selection and processing
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent applies preliminary action by pre-recording authentic cat purr frequency signals in a memory device before therapy sessions. This allows the therapy device to play back pre-validated therapeutic frequencies without requiring real-time cat interaction, ensuring reliable therapeutic effectiveness while simplifying the therapy delivery process.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent uses copying by recording the acoustic structure-borne noise signals from actual cat purrs and storing them digitally in memory. This creates accurate replicas of authentic purr frequencies that can be reproduced consistently through the sound transducer, ensuring therapeutic reliability without needing a live cat during treatment.

Inventive Principle:
Principle #26Copying

2Power

If the sound transducer uses a permanent magnet and electrical coil to generate vibrations, then effective biomechanical stimulation can be achieved, but the device requires precise electromagnetic control

Engineering Contradiction:
Improvevibration outputVSAvoidelectromagnetic control system
Core Design Contradiction:
PowerVSDevice complexity

Solution Approach 1:

The patent replaces complex mechanical vibration generation systems with an electromagnetic approach using a permanent magnet and electrical coil. The amplified purr frequency signals directly control the electromagnetic interaction, producing the required vibrations with simpler control electronics rather than complex mechanical mechanisms.

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

3Reliability

If the sound transducer is embedded in plastic or foam material for optimal transmission, then vibration transmission is improved, but the material must not absorb the purr frequency signals

Engineering Contradiction:
Improvevibration transmission efficiencyVSAvoidmaterial selection constraints
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent applies local quality by carefully selecting specific plastic or foam materials with appropriate acoustic transmission properties for the embedding medium. The material is chosen to have low absorption characteristics for purr frequency signals while providing good mechanical coupling, creating an optimized local environment for vibration transmission without compromising overall device adaptability.

Inventive Principle:
Principle #3Local quality

4Measurement precision

If the purr frequency signals are filtered to a bandwidth of 0-700 Hz, then therapeutic precision is improved, but signal processing complexity increases

Engineering Contradiction:

Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent applies parameter changes by implementing a frequency filter that limits the purr frequency signals to a specific bandwidth of 0-700 Hz. This frequency parameter control ensures that only the therapeutically relevant portion of the purr spectrum is transmitted, improving therapeutic precision while using standard filtering techniques to manage the processing complexity.

Inventive Principle:

AI summary

The apparatus has a sound transducer (8) for directing playback of string frequency signals (7) in a form of vibrations on a human or animal body. An amplifier (5) amplifies the string frequency signals stored in a storage unit (4) i.e. secure digital (SD)-card, forwarding amplified signals to the sound transducer. An impact sound microphone (2) is arranged at a larynx of a cat, and a recording device (3) i.e. computer, stores the string frequency signals in the storage unit. A filter limits the string frequency signals on a bandwidth between 0-700 Hertz.
