Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing synthetic yarn splicers face issues with yarns jumping out from the passage during the splicing operation due to the influence of injected fluid, leading to inefficiencies in the splicing process.
Innovation Solution
A synthetic yarn splicer design featuring a yarn splicing portion with a passage, injection hole, first and second clamping portions, and a shutter mechanism that closes the passage from either side to prevent yarns from jumping out, utilizing a cam mechanism and motor-driven shutter cam to control fluid flow and clamping actions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If fluid is injected from the injection hole to entangle the yarns, then the yarns are bound together, but the yarns jump out from the passage due to fluid influence
Solution Approach 1:
The shutter portion is positioned to close the passage before fluid injection occurs, preventing the harmful effect of yarn jumping out. By establishing this protective barrier in advance, the system counteracts the potential adverse effect of fluid-induced yarn displacement before it can occur.
Solution Approach 2:
The shutter portion acts as an intermediary element between the fluid injection system and the yarns. It controls and mediates the interaction by selectively opening to allow fluid flow for entanglement and closing to prevent yarn displacement, thus managing the harmful effects of fluid injection.
2Reliability
If the passage is closed by the shutter portion to prevent yarn jumping, then yarn stability is improved, but the fluid flow control mechanism becomes more complex
Solution Approach 1:
The shutter portion is designed to be movable and self-operating through the existing fluid injection system. The shutter opens when fluid pressure is applied and closes when pressure is released, allowing the system to control its own operation without requiring additional complex external actuation mechanisms.
Solution Approach 2:
The shutter portion transitions from a static closure to a dynamic, movable component that responds to fluid pressure changes. This dynamic design allows the shutter to automatically open during injection and close during non-injection periods, providing adaptive control without complex mechanical systems.
3Object-generated harmful factors
If the shutter portion closes the passage from one side, then yarn jumping is prevented, but the clamping portions must be positioned asymmetrically
Solution Approach 1:
The system intentionally employs asymmetric positioning of the shutter portion relative to the clamping portions. The shutter is positioned to close from one specific side of the passage, creating an asymmetric configuration that effectively prevents yarn jumping while maintaining functional simplicity through deliberate asymmetric design rather than complex symmetric mechanisms.
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
Effectively prevents yarns from jumping out during the splicing operation by actively managing fluid flow and clamping actions, ensuring stable entanglement and improved splicing efficiency.
Implementation Method 1
an injection hole opening to the passage and injecting a fluid and entangles the one yarn and the other yarn inserted through the passage
Implementation Method 2
the shutter portion closes the passage either from the one side with the first clamping portion being farther from the yarn splicing portion than the second clamping portion, or from the other side with the second clamping portion being farther from the yarn splicing portion than the first clamping portion when entangling the one yarn and the other yarn

AI summary
A splicer (66) includes a yarn splicing portion (66a), a first clamping portion (123), a second clamping portion (133), and a shutter mechanism (140). The yarn splicing portion (66a) includes a chamber (114) and an injection hole (116a) and entangles a first yarn (YA) and a second yarn (YB) inserted through the chamber (114). The first clamping portion (123) clamp the first yarn (YA) and the second yarn (YB). The second clamping portion (133) clamp the first yarn (YA) and the second yarn (YB). The shutter mechanism (140) can close at least a part of the chamber (114) and closes one side or a side far from the yarn splicing portion (66a) of the first clamping portion (123) and the second clamping portion (133) in the chamber (114) when entangling the first yarn (YA) and the second yarn (YB) using the yarn splicing portion (66a).
