Fixation Tape for Guide Member Attachment in Spinning Condenser
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fiber bundle condensing devices face increased costs and complexity due to the need for multiple components and complicated structures for fixing guide members to suction pipes, and the difficulty in replacing worn guide members without damaging the suction pipe or removing adhesive agents.
Innovation Solution
The use of a fixation tape to attach and detach guide members from the suction pipe, eliminating the need for screws or adhesives, allowing for easy replacement and reducing the number of components and operational complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a screw is used to fix the guide member to the suction pipe, then the guide member is securely fixed, but the number of parts increases and the structure becomes complicated
Solution Approach 1:
The invention extracts the fastening function from the main suction pipe structure by introducing a separate fixation tape. The fixation tape is attached to the suction pipe and the guide member is attached to the fixation tape, separating the fixing mechanism from the primary component. This reduces the complexity of the suction pipe structure while maintaining secure fixation.
Solution Approach 2:
The invention uses a fixation tape (a thin film structure) instead of rigid screws or complex fastening mechanisms. The fixation tape provides sufficient holding force while being simple in structure and easy to attach or remove, thereby reducing device complexity while maintaining fixing reliability.
2Reliability
If an adhesive agent is used to fix the guide member to the suction pipe, then the guide member is securely fixed, but replacement becomes troublesome and time-consuming
Solution Approach 1:
The invention extracts the adhesive bonding function and replaces it with a mechanical attachment system using fixation tape. The guide member is attached to the fixation tape which is itself attached to the suction pipe, allowing for easy detachment and replacement without the need to remove adhesive agents, thereby significantly reducing replacement time.
Solution Approach 2:
The fixation system is designed to be dynamically adjustable - the fixation tape can be easily attached and detached as needed. This dynamic characteristic allows for quick replacement of the guide member when wear occurs, eliminating the time-consuming process of removing adhesive agents and enabling rapid maintenance.
3Reliability
If screws are used to fix the guide member, then the guide member is securely fixed, but cotton fly can be caught by the complicated structure
Solution Approach 1:
The invention removes the screw fastening elements from the guide member attachment system. By using a fixation tape without protruding screws or complex mechanical fasteners, the structure becomes smooth and simple, preventing cotton fly from being caught in the fixing mechanism while maintaining secure attachment.
Solution Approach 2:
The fixation tape provides a smooth, flat surface for attachment that does not create protruding elements or complex structures where cotton fly could accumulate. This thin film approach maintains fixing reliability while eliminating the harmful effect of cotton fly entanglement.
