Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multi-point textile machines face functional and quality issues due to contamination from dust, fluff, and dirt, which are not optimally addressed by current cleaning systems that require manual input of cleaning parameters, leading to suboptimal or excessive cleaning.
Innovation Solution
The integration of sensors at critical contamination points that detect contamination levels and automatically control suction or compressed air applications through a central control device, allowing for targeted and objective cleaning without operator intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual cleaning parameters are used in existing cleaning systems, then the cleaning process can be controlled, but the cleaning effectiveness is suboptimal and energy waste occurs due to lack of objective contamination detection
Solution Approach 1:
The patent implements a feedback mechanism where sensors continuously monitor contamination levels at work stations and automatically adjust cleaning parameters. The control device receives contamination data from sensors and regulates the traveling unit's cleaning actions accordingly, creating a closed-loop system that prevents both insufficient cleaning and energy waste from excessive cleaning.
Solution Approach 2:
The cleaning system performs self-service by automatically detecting contamination and initiating cleaning operations without manual intervention. The sensors and control device enable the system to monitor and clean itself based on actual contamination levels, eliminating the need for operator input and optimizing energy usage.
2Measurement precision
If sensors and automatic control are integrated into the cleaning system, then cleaning precision and energy efficiency improve, but device complexity increases
Solution Approach 1:
The traveling unit serves multiple functions: it transports cleaning tools along the machine, houses sensors for contamination detection, contains the control device for automatic regulation, and executes cleaning operations. This multi-functionality reduces the need for separate dedicated components, thereby limiting the increase in device complexity while achieving precise contamination monitoring and control.
3Reliability
If continuous monitoring and automatic cleaning is implemented, then functional problems and quality issues are prevented, but the system requires more complex control mechanisms
Solution Approach 1:
The control device continuously receives feedback from sensors monitoring contamination at critical points such as the thread cleaner's measuring head and the paraffining device. Based on this feedback, the control device automatically regulates cleaning operations, ensuring functional reliability is maintained while using a relatively simple control architecture that processes sensor data and triggers appropriate cleaning actions.
