Solution Overview

Problem

Conventional red hot needles cause burns due to rapid heat transfer to the needle body and inflict pain due to the low abrasion resistance and tension of silver needle bodies.

Innovation Solution

A red hot needle design featuring a heated needle handle with a spiral groove, a silver needle handle, and a gold needle body, where the heat is diffused through the thicker needle handle before reaching the needle body, reducing the risk of burns and minimizing pain due to the higher abrasion resistance and tension of gold.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Temperature

If heat is applied primarily to the needle handle, then the needle body is quickly heated to high temperature, but this causes the patient to be burned

Engineering Contradiction:

Improveneedle body temperatureVSAvoidburn risk

Core Design Contradiction:

TemperatureVSObject-affected harmful factors

Solution Approach 1:

The patent introduces a heated needle handle as an intermediary component between the heat source and the needle body. This heated needle handle absorbs and diffuses the externally applied heat, then gradually transfers it to the needle body, preventing direct and rapid heating of the needle body that would cause burns to the patient.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent divides the needle structure into three distinct segments: the needle body, the needle handle, and the heated needle handle. This segmentation allows each part to have different thermal properties and functions, with the heated needle handle serving as a thermal buffer zone that controls the rate of heat transfer to the needle body.

Inventive Principle:

Principle #1Segmentation

2Strength

If the needle body is made of silver, then the manufacturing cost is lower, but the patient experiences pain due to low abrasion resistance and tension

Engineering Contradiction:

Improveabrasion resistance and tensionVSAvoidmanufacturing cost

Core Design Contradiction:

StrengthVSEase of manufacture

Solution Approach 1:

The patent applies local quality by using different materials for different parts of the needle. The needle body, which directly contacts the patient's tissue, is made of gold with high abrasion resistance and tension to reduce patient pain. The needle handle and heated needle handle are made of silver for cost-effectiveness, as these parts do not directly contact the patient.

Inventive Principle:

Principle #3Local quality

3Stability of the object's composition

If the needle handle has greater thickness, then the heat diffusion is improved, but the overall device complexity increases

Engineering Contradiction:

Improveheat diffusion stabilityVSAvoidstructural complexity

Core Design Contradiction:

Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The patent employs a nested structure where the heated needle handle is positioned on top of the needle handle, and both are concentrically arranged around the needle body. This nested doll-like structure allows for efficient heat diffusion through the thicker needle handle while maintaining a compact overall form factor, avoiding excessive device complexity.

Inventive Principle:

Principle #7Nested doll (Nesting)

AI summary

A red hot needle and a method for manufacturing the same wherein the red hot needle is provided with a heated needle handle located on top of a needle handle, so that heat applied to the heated needle handle diffuses into the needle handle and is slowly transferred to the needle body, thereby inhibiting a patient from being burned by the heat. The needle body is made of gold having relatively high abrasion resistance and tension, so that pain caused by insertion of the needle body is reduced. The a needle handle has greater thickness than the needle body, and the heated needle handle has lesser thickness than the needle handle. The method for manufacturing includes making the needle body of gold, making the needle handle and the heated needle handle of silver, attaching the needle body to the needle handle, and removing impurities from the needle by means of acidification.
