Solution Overview

Problem

Current treatments for chronic back pain, such as analgesics, injections, and electrical stimulation, provide inadequate long-term relief, are invasive, associated with side effects, and fail to address central pain sensitization.

Innovation Solution

An electrical stimulation device with percutaneous electrodes and a pulse generator activates peripheral nerves to stimulate paraspinal muscles, generating neurally encoded signals that modulate central pain processing, providing sustained pain relief without requiring muscle strengthening or mechanical stabilization.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If electrical stimulation is applied to activate muscles for pain relief, then pain relief is achieved, but muscle strengthening and mechanical stabilization are required which increases treatment complexity

Engineering Contradiction:

Improvepain reliefVSAvoidtreatment complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent extracts and isolates the essential therapeutic mechanism (afferent nerve signal generation) from the secondary effects (muscle strengthening, mechanical stabilization). By focusing solely on activating afferent nerves to modulate central pain processing, the treatment eliminates the need for complex muscle strengthening protocols and mechanical stabilization devices, reducing overall treatment complexity while maintaining pain relief effectiveness

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent replaces mechanical stabilization approaches with a neurological mechanism. Instead of using mechanical devices to stabilize the spine and support structures, the invention uses electrical stimulation to generate afferent nerve signals that modulate central pain processing, substituting a mechanical system with a neurological one that achieves the same therapeutic goal with less complexity

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Reliability

If invasive procedures are used to deliver electrical stimulation, then effective pain relief is achieved, but patient discomfort and side effects increase

Engineering Contradiction:

Improvepain relief effectivenessVSAvoidpatient discomfort

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent changes the parameter of stimulation delivery from invasive to non-invasive. By using surface electrodes or transdermal delivery methods instead of implanted electrodes, the treatment maintains effective electrical stimulation capability while eliminating surgical risks, infection concerns, and patient discomfort associated with invasive procedures. This parameter change allows the same therapeutic mechanism to be delivered without harmful factors

Inventive Principle:

Principle #35Parameter changes

3Duration of action of stationary object

If continuous therapy is administered to maintain pain relief, then sustained pain relief is achieved, but treatment duration and patient burden increase

Engineering Contradiction:

Improvepain relief durationVSAvoidtreatment time

Core Design Contradiction:

Duration of action of stationary objectVSLoss of time

Solution Approach 1:

The patent applies preliminary action by using brief, intermittent electrical stimulation sessions that generate afferent nerve signals to modulate central pain processing in advance. These short treatment sessions create lasting neurological changes that provide sustained pain relief without requiring continuous therapy. The preliminary stimulation action resets or modulates central pain processing mechanisms, resulting in prolonged therapeutic effects that reduce overall treatment time and patient burden
