Bendable Nose Stud Needle Tip for Tissue Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing nose studs with needle tips cause pain and wound bleeding due to the needle tip's larger diameter and inability to completely seal the wound, leading to tissue damage in the nasal cavity.
Innovation Solution
A nose stud with a needle tip connected to a needle bar featuring a bendable portion at the joint that bends when subjected to resistance, preventing tissue damage and ensuring the stud remains in place.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the needle tip diameter is made larger than the needle bar diameter to prevent the nose stud from falling off, then the nose stud remains in place, but the needle tip pricks tissues in the nasal cavity causing pain and the wound cannot be completely sealed leading to bleeding
Solution Approach 1:
The needle tip is designed with a bendable portion that allows it to dynamically change its configuration. During perforation, the needle tip is straight to penetrate the tissue. After perforation, when resistance is encountered, the bendable portion allows the needle tip to bend at an angle, creating a retention mechanism without requiring the tip to be permanently larger than the needle bar.
Solution Approach 2:
The needle tip's geometric parameters change during the perforation process. The bendable portion allows the needle tip to transition from a straight configuration during insertion to a bent configuration for retention. This dynamic parameter change enables the needle tip to be smaller than the needle bar while still achieving effective retention after bending.
2Object-affected harmful factors
If the needle tip diameter is made smaller to avoid tissue damage, then tissue irritation is reduced, but the nose stud may fall off after perforation
Solution Approach 1:
The needle tip transitions from a straight state during insertion to a bent state after perforation. This dynamic transformation allows a smaller needle tip to achieve retention functionality that would otherwise require a larger diameter, thereby reducing tissue irritation while preventing the stud from falling off.
Solution Approach 2:
The bendable portion is pre-designed to bend in a specific direction when resistance is encountered. This preliminary design of the bending behavior ensures that the needle tip will automatically form a retention hook after perforation, preventing the stud from falling off without requiring a larger initial tip diameter.
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 bendable joint reduces tissue irritation and prevents the nose stud from falling off, effectively minimizing pain and wound bleeding during and after the perforation process.
Implementation Method 1
a bendable portion, which bends when the needle tip is subjected to a resistance force under a force applied by the needle bar, is provided at a joint

AI summary
The present application provides a nose stud used for perforating and a perforating apparatus. The nose stud used for perforating comprises a needle tip and a needle bar, wherein the needle tip is connected to one end of the needle bar, and an easily bendable portion, which bends when the needle tip is subjected to a resistance force under a force applied by the needle bar, is provided at a joint. As a bendable structure is provided at the joint between the needle tip and the needle bar, the needle tip can bend relative to the needle bar after perforating the nose to avoid damaging tissues in the nasal cavity.
