Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing manufacturing process for thread lifting treatment apparatuses is complex as the thread and cannula are manufactured separately and then coupled, requiring additional installation steps.
Innovation Solution
A method to form a thread with barbs within a cannula, simplifying the manufacturing process by integrating the thread and cannula into a single unit, where the thread is inserted, twisted, and fixed using holders, then sterilized to maintain the barb formation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the thread and cannula are manufactured separately and then coupled, then the manufacturing flexibility is improved, but the manufacturing process complexity increases
Solution Approach 1:
The patent merges the thread and cannula into a single integrated structure where the thread is pre-formed with barbs and then inserted into the cannula during a single manufacturing process. This integration eliminates the need for separate manufacturing and coupling steps, thereby reducing manufacturing process complexity while maintaining flexibility through the modular design of the integrated unit.
Solution Approach 2:
The thread with barbs is pre-formed and prepared before insertion into the cannula. This preliminary action allows the thread to be manufactured with specific barb configurations optimized for skin engagement, while the integration into the cannula is performed as a preliminary step before sterilization, simplifying the overall manufacturing workflow.
2Ease of manufacture
If the thread is inserted through and coupled to the cannula separately, then the sterilization process is simplified, but the manufacturing time increases
Solution Approach 1:
The thread and cannula are integrated into a single assembly before sterilization. This merging allows both components to be sterilized together in one process, eliminating the need for separate sterilization steps and reducing overall manufacturing time while maintaining sterilization effectiveness.
Solution Approach 2:
The thread is pre-inserted into the cannula before the sterilization process. This preliminary assembly ensures that the thread and cannula are positioned correctly before sterilization, allowing the sterilization process to be applied to the complete assembly in a single step, thereby reducing manufacturing time.
3Reliability
If the thread has 3D-shaped barbs formed within the cannula, then the skin lifting effect is improved, but the manufacturing precision requirements increase
Solution Approach 1:
The barb shape is changed from conventional 2D to 3D configuration, which improves skin engagement and lifting effect. The 3D barbs are formed by controlling the thread formation process parameters, allowing the barbs to protrude in multiple directions for enhanced mechanical interlocking with skin tissue.
Solution Approach 2:
The thread with 3D barbs is pre-formed with the barb structures already in place before insertion into the cannula. This preliminary formation of the 3D barbs ensures consistent geometry and positioning, reducing the need for high-precision alignment during insertion while maintaining the enhanced skin lifting effect.
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
This integration simplifies the manufacturing process and enhances the skin lifting effect by providing a thread with 3D-shaped barbs that engage the skin more effectively than conventional 2D-shaped barbs, improving collagen production and lifting efficacy.
Implementation Method 1
a predetermined temperature may be applied to the cannula to maintain a twist of the preform of the thread and to form the plurality of barb preforms into the plurality of barbs

AI summary
A method of manufacturing a treatment apparatus for lifting skin according to the present disclosure and a treatment apparatus for lifting skin manufactured using the same allow a thread for a skin lifting treatment, having a plurality of barbs, to be formed within a cannula for commercial sale SO that separate manufacturing and installation of the thread into the cannula are unnecessary. Therefore, the thread may be sold with the cannula in a configuration formed within the cannula, thereby simplifying the manufacturing process.
