Slow-Expanding Piercing Needle for Low-Trauma Jewelry Insertion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional piercing needles cause significant pain, excessive bleeding, susceptibility to infection, slow wound recovery, and require troublesome long-term care due to their thickness and the difficulty in fitting jewelry, often leading to failed piercings and foreign body irritation.
Innovation Solution
A painless slow-expanding piercing needle with a diameter not greater than 0.3 mm, featuring a wire with one end curled into a spiral tube shape, which is separated and curled on both sides of the wound, allowing for gradual expansion and closure of the wound after healing, assisted by a wire curling rod for jewelry insertion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional thick piercing needle (0.8-4 mm) is used, then jewelry can be directly introduced after piercing, but piercing pain is intolerable, excessive bleeding occurs, and infection risk increases
Solution Approach 1:
The piercing process is divided into two separate stages: first creating a small puncture wound with a fine needle (≤0.3mm), then gradually expanding the wound over time. This segmentation allows the initial piercing to be painless while jewelry introduction is achieved through gradual expansion rather than direct insertion.
Solution Approach 2:
The patent performs preliminary action by creating a small puncture wound first, then allowing the wound to heal partially before gradual expansion. This preliminary piercing with a fine needle minimizes initial trauma, and subsequent expansion is done progressively to avoid pain and bleeding.
2Reliability
If a thick piercing needle is used, then jewelry rod can fit the wound, but the wound cannot fit closely with the jewelry rod causing foreign body irritation
Solution Approach 1:
The wound is made dynamic through gradual expansion. Instead of creating a static large opening that may not fit jewelry precisely, the wound starts small and expands progressively to match the jewelry dimensions exactly, ensuring close fit and eliminating foreign body irritation.
Solution Approach 2:
The wound diameter parameter is changed gradually over time through controlled expansion. The wound starts with a small diameter (≤0.3mm) and increases progressively until it matches the jewelry rod diameter, ensuring precise fit and eliminating gaps that cause irritation.
3Productivity
If a thick piercing needle is used, then piercing can be completed quickly, but wound recovery is slow and care is troublesome for several months
Solution Approach 1:
The piercing process is segmented into a quick initial puncture (≤0.3mm needle) followed by gradual expansion phases. The initial puncture is completed quickly, and the expansion is performed in manageable stages, reducing overall recovery time and care requirements compared to creating a large wound in one step.
Solution Approach 2:
The patent applies beforehand cushioning by allowing the initial small wound to heal partially before expansion. This creates a cushion of healed tissue that protects against infection and complications during the expansion process, reducing overall care requirements and recovery time.
4Object-affected harmful factors
If a small diameter needle (≤0.3 mm) is used for piercing, then piercing pain is minimized and bleeding is reduced, but the wound requires gradual expansion to accommodate jewelry
Solution Approach 1:
The expansion process is designed to be self-service, where the user or practitioner can perform the expansion themselves using the same wire instrument. The wire is manipulated to gradually expand the wound in a controlled manner, eliminating the need for additional specialized tools or complex procedures.
Solution Approach 2:
The wire instrument serves multiple functions: it creates the initial puncture wound, acts as a placeholder during healing, and is used to gradually expand the wound. This multi-functionality reduces device complexity by using a single versatile tool rather than multiple specialized instruments.

AI summary
A painless slow-expanding piercing needle and a method for using same are disclosed. The painless slow-expanding piercing needle includes: a piercing needle with a diameter not greater than 0.3 mm; and a wire having a first end and a second end. The first end has a greater diameter than second end, the second end is connected to the piercing needle, and the first end is curled into a spiral tube shape. After piercing from one side to form a wound, the piercing needle is separated from second end, and the second end is curled into a spiral tube shape and curled up at the other side of the wound. After the wound heals, uncurling the first end by a length, moving the wire toward the second end to a proper position and curling the first and the second ends tightly are performed for several times until hole expansion is achieved.
