Spinning Machine Master Terminals for Multi-Station Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing spinning or winding machines with multiple work stations require operators to be present at each station for manual control, which is inefficient and prone to issues like battery-dependent wireless terminal failures and interference.
Innovation Solution
Implementing multiple input terminals that can function as master terminals, allowing operators to control all work stations individually and remotely, with priority inputs sent to a central or decentralized control unit, and display devices for real-time feedback, eliminating the need for constant operator presence and addressing wireless connectivity issues.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If operators control work stations from individual locations, then operator presence is required at each station, but this reduces operational efficiency and increases time loss
Solution Approach 1:
The patent implements master terminals that can be located at different positions along the spinning or winding machine, with each master terminal capable of controlling multiple work stations. This multi-functional design allows a single operator to control multiple stations from one location, eliminating the need for operators to physically present at each workstation while maintaining full control capability.
Solution Approach 2:
The patent introduces master terminals as intermediary devices between operators and work stations. These master terminals serve as control interfaces that mediate the interaction between operators and multiple work stations, allowing remote control without requiring direct physical presence at each station. The master terminal acts as a mediator that transmits control signals to multiple work stations simultaneously.
2Ease of operation
If wireless hand-held terminal devices are used, then operator mobility is improved, but battery dependency and wireless transmission issues arise
Solution Approach 1:
The patent segments the control system into multiple fixed master terminals distributed along the machine, each serving specific work stations. This segmentation replaces the need for a single mobile wireless terminal with multiple localized control points, eliminating battery dependency and wireless transmission issues while maintaining operator accessibility to all work stations.
3Adaptability or versatility
If multiple input terminals are designed to serve as master terminals, then control flexibility is improved, but device complexity increases
Solution Approach 1:
The patent combines the functionality of multiple master terminals into a unified control system where each terminal can serve as a master terminal for different work stations. This merging of functions allows any terminal to take on the master role as needed, providing control flexibility without requiring entirely separate systems for each control point. The terminals share common control logic and communication protocols, managing complexity through standardization.
