Solution Overview

Problem

The existing light therapy devices with negative ion functionality face the risk of infection due to the protruding bulge on the patient's body being stabbed by the releasing needle during negative ion therapy, which is formed by the negative-pressure cup's suction.

Innovation Solution

A light therapy device incorporating a negative-pressure cup with a needle protection cap to shield the releasing needle, preventing it from stabbing the patient's bulge and ensuring safe and effective light and negative ion therapy.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a releasing needle is used to release negative ions, then negative ion therapy function is achieved, but the patient's bulge may be stabbed by the needle causing infection risk

Engineering Contradiction:

Improvenegative ion therapy functionVSAvoidinfection risk from needle stabbing

Core Design Contradiction:

Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

A releasing needle cap is introduced as an intermediary component between the releasing needle and the patient's skin. The cap covers the releasing needle when not in use, preventing direct contact with the patient's bulge while allowing negative ion release functionality when needed. This mediator eliminates the harmful stabbing effect while preserving the useful negative ion therapy function.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If the negative-pressure cup creates a bulge on the patient's body, then light therapy and negative ion attachment effectiveness is improved, but the bulge protrudes toward the releasing needle increasing stabbing risk

Engineering Contradiction:

Improvelight therapy and negative ion attachment effectivenessVSAvoidstabbing risk to bulge

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The releasing needle cap is installed in advance before the negative-pressure cup creates the bulge. This preliminary protective action ensures that when the bulge forms and protrudes toward the releasing needle, the needle is already shielded by the cap, preventing stabbing while allowing the bulge to form for effective therapy.

Inventive Principle:

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

The needle protection cap effectively prevents stabbing injuries, enhancing the safety and efficacy of light and negative ion therapy by ensuring the needle does not come into contact with the patient's bulge, thus reducing the risk of infection and improving therapy outcomes.

AI summary

A light therapy device used for a negative-pressure cup is provided. The light therapy device includes a carrier, a light therapy assembly, a negative ion assembly and a needle protection cap. The carrier is disposed in the negative-pressure cup and includes a panel. The light therapy assembly and the negative ion assembly are disposed in the carrier. The negative ion assembly includes a releasing needle. The releasing needle projects out from the panel to release negative ions. The needle protection cap covers the panel corresponding to the releasing needle to shield the releasing needle. Therefore, the light therapy assembly and the negative ion assembly may be associated with the negative-pressure cup for usage, and the needle protection cap may prevent the user from being stabbed.
