Infusion Tag With Slit Pattern For Knotless Thread Fixation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for attaching a tag to a cotton thread for infusion products require complex and costly equipment, such as needles or aspirating elements, which are prone to damage and require frequent maintenance due to the need for knotting the thread.
Innovation Solution
A tag design featuring three slits, including a first slit and two additional slits that converge towards a straight line perpendicular to the first slit, allowing the thread to be passed through without knotting, providing stable fixation by resisting unthreading.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a knot is made in the thread to fix the tag to the thread, then the tag can be securely attached, but the equipment complexity and maintenance requirements increase
Solution Approach 1:
The tag is divided into multiple parts including a head portion and a body portion, with the head portion containing multiple holes arranged in a specific pattern. This segmentation allows the thread to be threaded through multiple holes to create a secure attachment without requiring complex knotting equipment.
Solution Approach 2:
The head portion of the tag acts as an intermediary element between the thread and the bag. The multiple holes in the head portion provide a structured interface that simplifies the thread attachment process, eliminating the need for complex needles or aspirating elements while ensuring reliable fixation.
2Ease of manufacture
If complex equipment such as needles or aspirating elements is used to attach the tag, then the tag can be fixed to the thread, but the equipment requires frequent maintenance and replacement
Solution Approach 1:
The tag design enables self-service attachment without requiring external complex equipment. The multiple holes in the tag's head portion allow the thread to be directly threaded and secured through simple manual or automated insertion, eliminating the need for maintenance-prone needles or aspirating elements.
Solution Approach 2:
The tag with its integrated hole pattern replaces expensive, maintenance-intensive equipment like needles and aspirating elements. The tag itself becomes a disposable or replaceable component that simplifies the overall system, eliminating the need for costly equipment maintenance and replacement.
3Reliability
If the thread is threaded through multiple holes and folded to make a knot, then the tag is secured to the thread, but the process time increases
Solution Approach 1:
The holes are pre-positioned in the tag's head portion in an optimal pattern that facilitates quick thread insertion and secure attachment. This preliminary arrangement of holes eliminates the need for complex threading patterns and lengthy knot-tying processes, reducing attachment time while maintaining fixation stability.

AI summary
A tag to be fixed to a connecting thread to a filter bag for infusion products has a flat body delimited by a perimeter edge; a first slit, starting from a first point of a side of the perimeter edge; a second slit and a third slit, starting from respective points of such side of the perimeter edge arranged on opposite sides with respect to the first starting point of the first slit. At least one of the second and third slits exhibits, starting from the respective starting point on said side, a progression and a development directed towards a point of a straight line in the plane of the body of the tag and perpendicular to said side at the first starting point of the first slit; the first slit, the second slit and the third slit being such as to enable passage there-through of a connecting thread, for fixing the tag to the thread.
