Solution Overview

Problem

Limited access to healthcare and high costs prevent many individuals from obtaining dry needling services for musculoskeletal pain relief, which are typically administered by clinicians.

Innovation Solution

A handheld device designed for self-administration of dry needling therapy, allowing users to control needle depth and ejection force, equipped with mechanisms for needle storage, deployment, and safety features, enabling at-home treatment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If dry needling is performed by clinicians in healthcare settings, then treatment effectiveness is ensured, but accessibility and cost-effectiveness deteriorate

Engineering Contradiction:

Improvetreatment effectivenessVSAvoidaccessibility

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The device enables patients to perform dry needling therapy themselves at home, eliminating the need for clinician intervention. The handheld device includes automated needle deployment mechanisms and depth control features that allow laypersons to safely administer treatment without medical training.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The device acts as an intermediary between the patient and the therapeutic needle insertion process. It provides automated needle handling, deployment, and depth control, serving as a mediator that transfers the clinical procedure into a home-based self-service format while maintaining treatment integrity.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Device complexity

If manual needle insertion is used, then device complexity is reduced, but insertion precision and safety deteriorate

Engineering Contradiction:

ImprovesimplicityVSAvoidinsertion depth control

Core Design Contradiction:

Device complexityVSMeasurement precision

Solution Approach 1:

The device incorporates adjustable depth control mechanisms that allow dynamic modification of needle insertion depth during use. The system transitions from static manual insertion to dynamic controlled deployment, enabling precise depth adjustment while maintaining relatively simple overall device architecture.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The device replaces manual mechanical needle insertion with an automated deployment mechanism. This substitution provides precise depth control through mechanical guidance systems while keeping the overall device structure relatively simple and manageable for home use.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Quantity of substance

If reusable needles are used, then cost is reduced, but sterility and safety deteriorate

Engineering Contradiction:

ImprovecostVSAvoidinfection risk

Core Design Contradiction:

Quantity of substanceVSObject-affected harmful factors

Solution Approach 1:

The device is designed to work with disposable, single-use needles that are discarded after each use. This approach eliminates infection risks associated with reusable needles while maintaining cost-effectiveness through the use of inexpensive, single-use components. The disposable nature ensures sterility and safety without requiring expensive sterilization processes.

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)
