Suture Dispensing Package With Interlocking Carrier Plates
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing suture packaging is structurally complex, costly to produce, and makes it difficult to easily remove needles from within the winding channel, with elastic sutures prone to springing out and knotting during removal.
Innovation Solution
A dispensing package comprising a thread carrier with two interlocking oval or ring-like plates and an outer packaging that allows easy assembly and fixation of needles outside the channel, using paper or cardboard for the outer packaging and plastic for the carrier, with opposing elevations to reduce friction and facilitate needle removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If needles are fixed inside the winding channel, then the packaging is compact, but needle removal becomes difficult and complex
Solution Approach 1:
The packaging is divided into two functional zones: the winding channel for suture material and a separate needle storage element. This segmentation allows needles to be stored externally where they can be easily accessed and removed, while maintaining compact packaging through the integrated design of the two zones.
Solution Approach 2:
The needle storage function is extracted from the winding channel and placed in a separate needle storage element. This extraction allows needles to be easily removed without disturbing the suture material winding, solving the problem of difficult needle removal while maintaining packaging compactness.
2Volume of moving object
If elastic suture material is wound in a tight channel, then the packaging is compact, but the suture is prone to springing out and knotting during removal
Solution Approach 1:
The packaging provides different structural characteristics in different zones: the winding channel has specific wall properties to control suture winding tension, while the needle storage element provides a separate compartment. This local quality differentiation prevents suture springing by maintaining appropriate tension distribution while allowing compact packaging.
Solution Approach 2:
The packaging design incorporates structural elements that preemptively prevent suture springing and knotting by maintaining controlled tension during the entire process, from winding to needle removal, eliminating harmful effects before they occur.
3Ease of operation
If complex multi-part packaging is used, then needle removal can be facilitated, but production cost and device complexity increase
Solution Approach 1:
The packaging merges the winding channel and needle storage element into a single integrated structure that can be manufactured as one piece or pre-assembled units. This merging reduces the number of separate components and simplifies production while maintaining easy needle removal capability.
Solution Approach 2:
The packaging structure serves multiple functions simultaneously: it winds and secures the suture material, stores and positions the needle, and provides a user interface for easy needle removal. This multi-functionality reduces overall complexity by eliminating the need for separate specialized components.
