Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cabling machines face difficulties in quickly and conveniently feeding creel yarn due to the use of movable platforms that hinder accessibility and increase workplace load, making it challenging to rectify yarn breakages and maintain a stable yarn path.
Innovation Solution
A creel yarn feed apparatus with a tubular body and compressed air device that guides the yarn through a channel with controlled air flow, allowing easy access and reliable feeding without the need for step elevations, and optionally eliminating the need for yarn brakes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If movable platforms are used to access bobbin creels, then yarn feeding becomes easier, but machine accessibility and workplace safety deteriorate
Solution Approach 1:
The patent replaces the mechanical movable platform system with a pneumatic air flow system. Compressed air is directed through nozzles positioned near the bobbin creels to propel yarn along a defined path, eliminating the need for physical platforms while maintaining ease of yarn feeding operation.
Solution Approach 2:
The invention uses compressed air as a pneumatic medium to transport yarn from the bobbin creels to the cabling apparatus. Air nozzles positioned at strategic locations create controlled air streams that guide yarn through the workspace, replacing mechanical access methods with a fluid-based transport system.
2Ease of operation
If step elevations are installed for yarn access, then yarn feeding is facilitated, but workplace load and accessibility worsen
Solution Approach 1:
The patent replaces mechanical step elevations with a pneumatic yarn propulsion system. Compressed air streams directed through nozzles positioned at ergonomic heights propel yarn horizontally and vertically without requiring physical elevation structures, eliminating workplace load while maintaining ease of yarn access.
Solution Approach 2:
The invention transitions from vertical mechanical elevation (steps/platforms) to horizontal pneumatic propulsion. Yarn is transported through three-dimensional air streams that can reach elevated positions without requiring physical staircases or platforms, solving the workplace load problem while maintaining accessibility.
3Stability of the object's composition
If rigid creels are used, then structural stability improves, but yarn feeding complexity increases
Solution Approach 1:
The patent introduces a pneumatic air flow system that works with rigid creels to simplify yarn feeding. Compressed air directed through positioned nozzles propels yarn from rigid creels along defined paths, eliminating the need for complex manual threading procedures while maintaining the structural stability of rigid creel installations.
