Mobile Drawing-In Machine Unit for Weaving Accessories Handling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drawing-in machines require significant space and are cumbersome to maintain due to fixed components, making it difficult to exchange or refit weaving accessories trolleys, which hinders efficient and space-saving operation.
Innovation Solution
A mobile unit with movable holding means for a reed, healds, drop wires, and thread sheets, allowing for automated drawing-in and easy removal or insertion, utilizing hollow profiles for enhanced rigidity and connectivity, and eliminating the need for stationary machine components on the unloading side.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the holding means for the reed is fixed immovably to the drawing-in machine, then the machine structure is stable, but the weaving accessories trolley cannot be removed from the machine and requires huge installation space
Solution Approach 1:
The patent divides the holding means for the reed into a separate, movable component that can be detached from the drawing-in machine. This segmentation allows the weaving accessories trolley to be removed independently without affecting the stability of the main machine structure, resolving the contradiction between ease of operation and device complexity.
Solution Approach 2:
The holding means for the reed is designed to be movable rather than fixed, enabling dynamic reconfiguration of the system. This allows the trolley to be easily removed and reinstalled while maintaining structural stability during operation, addressing both the removability requirement and the structural integrity need.
2Ease of manufacture
If the holding means for the reed is fixed immovably to the drawing-in machine, then the machine structure is stable, but it is difficult and time-consuming to exchange or refit the weaving accessories trolley
Solution Approach 1:
By segmenting the holding means into a detachable component, the patent enables quick exchange of the trolley without requiring complex disassembly of the entire machine structure. This reduces both the difficulty and time associated with refitting operations.
Solution Approach 2:
The holding means is pre-designed with attachment and detachment mechanisms that facilitate rapid exchange. This preliminary preparation of the connection interface allows for quick refitting operations without requiring extensive setup or adjustment time.
3Area of stationary object
If the holding means for the reed is fixed immovably to the drawing-in machine, then the machine structure is stable, but the amount of space required for the machine is huge
Solution Approach 1:
The movable holding means allows the system to be reconfigured in a compact arrangement when the trolley is not in use. The trolley can be removed and placed beside the machine rather than requiring dedicated space within the machine structure, significantly reducing the overall installation footprint.
Solution Approach 2:
By separating the holding means from the main machine structure, the patent allows for more flexible space utilization. The trolley can be positioned externally when not needed, reducing the space requirements of the stationary machine while maintaining structural stability during operation.
