Solution Overview

Problem

Existing light therapy devices for musculoskeletal pain and tissue healing are inconvenient for self-administration, particularly for hard-to-reach areas, and often require bulky batteries or external power, limiting their portability and ease of use.

Innovation Solution

A dual modality system combining a durable energy subsystem with a replaceable thermal subsystem, featuring a flexible chassis and adhesive surface for secure attachment to the body, allowing for continuous or intermittent energy delivery, including light and thermal therapy.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the device is made self-contained with integral housing and battery pack, then the device is more portable and convenient for home use, but the device becomes heavier and bulkier

Engineering Contradiction:
Improveconvenience for home useVSAvoiddevice weight
Core Design Contradiction:
Ease of operationVSWeight of moving object

Solution Approach 1:

The device is divided into two main segments: a reusable control unit containing the processor and light delivery mechanisms, and a replaceable power unit containing the battery pack. This segmentation allows the user to carry only the lightweight control unit during treatment, while the heavier battery pack remains stationary or is replaced as needed, thus reducing the weight burden during actual use.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The battery pack is extracted from the integral housing and made as a separate replaceable unit. This extraction allows the main device body to be significantly lighter and more portable, while the heavy power source can be kept separately or replaced without carrying it during treatment sessions.

Inventive Principle:
Principle #2Taking out (Extraction)

2Duration of action of moving object

If the device is held in position by the user for extended periods, then the treatment can be administered, but the user experiences discomfort and fatigue

Engineering Contradiction:
Improvetreatment durationVSAvoiduser comfort
Core Design Contradiction:
Duration of action of moving objectVSEase of operation

Solution Approach 1:

The device incorporates self-adjustment mechanisms including automatic positioning aids and feedback systems that allow the device to maintain optimal treatment position without requiring continuous active holding by the user. The system can automatically adjust parameters and maintain contact pressure, enabling hands-free or minimal-touch operation during extended treatment periods.

Inventive Principle:
Principle #25Self-service

3Duration of action of moving object

If the device is strapped to the body for treatment, then the device remains in position, but the user cannot see or access the control display

Engineering Contradiction:
Improvetreatment stabilityVSAvoidaccess to control panel
Core Design Contradiction:
Duration of action of moving objectVSEase of operation

Solution Approach 1:

The control interface is moved from the front face of the device to the rear side or to a remotely accessible location. This dimensional repositioning allows the user to strap the device to any body part including the back, while still being able to access and view the control display from behind or from a distance, eliminating the visibility problem.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

4Area of stationary object

If light therapy is delivered to the entire body surface, then comprehensive coverage is achieved, but the risk of cellular damage and burns increases

Engineering Contradiction:
Improvetreatment area coverageVSAvoidcellular damage and burns
Core Design Contradiction:
Area of stationary objectVSObject-affected harmful factors

Solution Approach 1:

The device incorporates sensors and control mechanisms that detect tissue characteristics and automatically adjust light intensity and duration for each specific treatment location. Different areas of the body receive customized light dosages based on their individual needs and sensitivity, ensuring optimal therapeutic effect while preventing overtreatment and potential damage to any particular region.

Inventive Principle:
Principle #3Local quality
