Solution Overview

Problem

Existing timekeeping devices are disruptive and impractical in environments where minimal distraction is desired, such as meditation, yoga, and therapy, due to ticking sounds and alarms.

Innovation Solution

A timer with a sound generator, comprising a rotating disc and a drive mechanism, uses a sound-generating element held in position by a detent surface, which is deflected to produce a sound at a defined interval without ticking noise, suitable for blind or visually impaired users.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a mechanical clockwork or alarm device is used for interval time measurement, then time measurement function is achieved, but ticking noise and disruptive alarm sounds are generated

Engineering Contradiction:
Improvetime measurement functionVSAvoidticking noise and disruptive alarm sounds
Core Design Contradiction:
ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The patent extracts and eliminates the ticking mechanism and disruptive alarm components from traditional timekeeping devices. Instead of using mechanical clocks or electronic alarms that produce disturbing sounds, the invention uses a quiet rotary dial mechanism combined with a gentle acoustic signal (ping pong ball dropping into a cup) to indicate time intervals, thereby removing the harmful noise factors while preserving the time measurement function

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent employs simple, inexpensive components such as a ping pong ball and a cup to generate the alarm signal. These are transient, low-cost elements that produce a single gentle sound when the ball drops, replacing complex and expensive alarm mechanisms while achieving the desired non-disruptive alert function

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

2Reliability

If traditional alarm devices are used, then time interval indication is achieved, but the alarm sound is disruptive and unpleasant

Engineering Contradiction:
Improvetime interval indicationVSAvoidunpleasant alarm sound
Core Design Contradiction:
ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The patent converts what could be a harmful disruptive alarm into a beneficial gentle acoustic signal. By using a ping pong ball dropping into a cup, the invention transforms the alarm function into a soft, pleasant sound that is easily distinguishable but not disturbing, thereby converting a potential harm (disruptive sound) into a benefit (gentle, pleasant indication)

Inventive Principle:
Principle #22Blessing in disguise (Convert harm into benefit)

3Loss of information

If visual displays are used on timers, then time information is clearly shown, but the device becomes less accessible to blind or visually impaired users

Engineering Contradiction:
Improvetime information displayVSAvoidaccessibility to visually impaired users
Core Design Contradiction:
Loss of informationVSAdaptability or versatility

Solution Approach 1:

The patent segments the time measurement function into tactile and acoustic components rather than relying on visual displays. The rotary dial provides tactile feedback for setting time intervals, and the acoustic signal (ball dropping sound) provides clear indication of time elapsed, thereby segmenting the information delivery channels to accommodate users with visual impairments while maintaining clear time information communication

Inventive Principle:
Principle #1Segmentation

4Measurement precision

If electronic timers are used, then precise time measurement is achieved, but the device produces electromagnetic radiation and technical distractions

Engineering Contradiction:
Improvetime measurement precisionVSAvoidelectromagnetic radiation and technical distractions
Core Design Contradiction:
Measurement precisionVSObject-generated harmful factors

Solution Approach 1:

The patent replaces electronic and digital components with a simple mechanical rotary dial system for time measurement. The mechanical rotation of the dial, combined with a quiet drive mechanism, achieves precise interval timing without generating electromagnetic radiation or technical distractions, thereby substituting mechanical simplicity for electronic complexity

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

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

Provides a non-disruptive, intuitive, and pleasant alarm tone for interval time measurement, suitable for various environments and user groups, including visually impaired individuals.

Implementation Method 1

the deflecting mechanism exerts a force – be it a mechanical force, a magnetic force, or something similar – on at least one sound-generating element at a specific point in time

Methodology Applied
Scientific EffectMechanical force: Mechanical Force

Implementation Method 2

the deflecting mechanism exerts a force – be it a mechanical force, a magnetic force, or something similar – on at least one sound-generating element at a specific point in time

Methodology Applied
Scientific EffectMagnetic force: Magnetic Field

Implementation Method 3

the sound-stimulating element is thus deflected from its position in the resting surface by the deflection device after a defined period of time and moved towards the sound generator, preferably by gravity

Methodology Applied
Scientific EffectGravity: Gravitation

AI summary

Timer comprising a sound generator, at least one sound-stimulating element, a drive and a disk moved by it, wherein the moving disk has at least one detent surface for temporarily holding the at least one sound-stimulating element in position, wherein the timer has at least one deflection element relative to which the disk moves, such that the deflection element exerts a force on the at least one sound-stimulating element at a certain time, which sets the sound-stimulating element in motion towards the sound generator and finally causes it to sound.
