Solution Overview

Problem

Existing portable devices for relieving pains and spasms through electrical pulses often suffer from untimely static electricity discharges, which are painful and deter users due to uncontrolled voltage and discharge arcs, especially when used on the skin or through fabrics.

Innovation Solution

A relief device with adjustable static electricity discharge elements and an activation triggering mechanism that ensures electrical pulses are delivered only when the device is applied to the skin, using capacitors and sensors to manage discharge voltage and prevent parasitic discharges, thereby adapting to user sensitivity.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the relief device is applied onto the user before starting alternating back-and-forth movement, then the device is ready to deliver electrical pulses, but static electricity discharges occur causing pain and discomfort

Engineering Contradiction:

Improvedevice readinessVSAvoidstatic electricity discharges

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The device performs preliminary action by accumulating static electricity on the electrodes during handling and transport, but the harmful discharge is prevented by the triggering mechanism that requires actual application to the user's body before pulse delivery begins. The static charge builds up in advance but remains harmless until the proper activation condition is met.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The device uses feedback from the application condition to control pulse delivery. The triggering mechanism detects when the device is actually applied to the user's body and only then activates the electrical pulse delivery, preventing premature discharges. This feedback loop ensures that static electricity is discharged safely only when the device is properly positioned on the user.

Inventive Principle:

Principle #23Feedback

2Reliability

If the voltage of electrical pulses is increased to improve relief effectiveness, then pain relief is enhanced, but static electricity discharges become more violent and painful

Engineering Contradiction:

Improvepain relief effectivenessVSAvoiddischarge voltage

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The device changes the parameter of voltage delivery by using a triggering mechanism that activates pulse delivery only after the device is applied to the user's body. This temporal parameter change ensures that high voltage pulses are delivered at the appropriate moment when the device is in contact with the skin, maximizing pain relief effectiveness while preventing premature or violent discharges.

Inventive Principle:

Principle #35Parameter changes

3Ease of operation

If the relief device is brought towards the user's skin without contact, then the device appears to be activated, but electric arcs are generated causing pain

Engineering Contradiction:

Improveactivation detectionVSAvoidelectric arcs

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The triggering mechanism provides feedback that distinguishes between mere proximity and actual contact application. It detects the specific condition of the device being applied to the user's body and only then activates pulse delivery, preventing electric arc generation that occurs when the device is merely brought close to the skin without proper contact.

Inventive Principle:

Principle #23Feedback

AI summary

A device for relieving pains and spasms by applying electrical pulses which makes it possible to render the electrical pulses easier to tolerate by limiting or preventing the painful or untimely discharges which hamper the use of the relief device. The relief device delivers electrical pulses only when it bears or rolls in a back-and-forth movement on the skin or clothing of a user. The relief device comprises means for limiting the maximum voltage delivered to the user, one or more means of triggering the pulses delivered by the electrodes, an activation delayer and a system for progressively launching the potential delivered by the electrodes.
