Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional biodegradable thread manufacturing apparatuses have low productivity due to the use of single-bladed parts, leading to a lengthy process for forming cogs on biodegradable threads, which are used in thread lifting surgeries for wrinkle removal, and require a more rapid and simpler method to enhance production efficiency and coupling force with skin tissues.
Innovation Solution
A biodegradable thread manufacturing apparatus with a multi-bladed part that forms cogs with two or more separated peaks on the thread through a one-time operation, utilizing a cog formation unit with multiple blade members to improve production efficiency and enhance the coupling force with skin tissues.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a single-bladed part is used to form cogs on the biodegradable thread, then the structure is simple, but the production efficiency is low due to the lengthy process
Solution Approach 1:
The single blade is divided into multiple blade members (first blade member, second blade member, third blade member) arranged in sequence. Each blade member forms a portion of the cog structure, allowing the cog to be created in a single pass through the thread rather than requiring sequential processing with a single blade, thereby improving production efficiency while maintaining structural manageability
Solution Approach 2:
Multiple blade members are combined into a single integrated blade part structure that operates simultaneously. The blade members are positioned at different angles and locations to collectively form the complete cog geometry in one operation, merging multiple cutting actions into a single coordinated process that enhances productivity without excessive complexity
2Loss of time
If a single-bladed part is used to form cogs, then the device complexity is low, but the process time is lengthy
Solution Approach 1:
The cog formation process is segmented into multiple simultaneous cutting actions performed by different blade members. The first blade member creates the initial groove, the second blade member forms the peak, and the third blade member completes the cog structure, all occurring in parallel during a single thread pass, significantly reducing process time compared to sequential single-blade operations
Solution Approach 2:
The blade members are pre-positioned at specific angles and locations before the thread passes through. The first blade member is positioned to create the groove at the correct angle, the second blade member is pre-set to form the peak at the appropriate position, and the third blade member is arranged to complete the cog shape, ensuring all cutting actions occur in optimal sequence without adjustment during operation
3Strength
If conventional single-blade manufacturing is used, then the manufacturing process is simple, but the coupling force with skin tissues is insufficient
Solution Approach 1:
The cog structure is segmented into multiple peaks and grooves formed by separate blade members. This segmentation creates a more complex cog geometry with multiple contact points (peaks) that can engage with skin tissues at different locations, increasing the overall coupling force and mechanical interlocking effect compared to simpler single-peak cogs from conventional single-blade processes
Solution Approach 2:
Different blade members create different local features on the cog structure. The first blade member forms the groove with specific depth and angle for tissue engagement, the second blade member creates the peak with optimized curvature for skin contact, and the third blade member refines the cog shape. This local optimization of each cog feature enhances the overall coupling force with skin tissues while maintaining manufacturability through a systematic multi-blade approach
