Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional yarn winding devices face issues with excessive vibration during high-speed operation, leading to potential damage of electronic components and reduced productivity due to the limitations of vibration detection systems, which are often affected by noise and time lags in signal processing.
Innovation Solution
A circuit board with a vibration detecting chip and signal processing section is integrated into the yarn winding device, allowing for immediate detection and control of vibrations, reducing the risk of component damage and enabling efficient operation by decreasing winding speed or interrupting the process if necessary.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the winding speed is increased to improve productivity, then the production efficiency is improved, but the vibration on the unit frame is excessively increased causing electronic component damage
Solution Approach 1:
The vibration detecting sensor detects abnormal vibrations before they cause damage to electronic components. The control board receives the detection signal and preemptively adjusts the winding speed or stops the operation to prevent component damage, rather than waiting for damage to occur.
Solution Approach 2:
The vibration detecting sensor continuously monitors the unit frame and provides feedback signals to the control board. Based on this feedback, the control board automatically adjusts the winding speed to maintain optimal operation while preventing excessive vibration that could damage electronic components.
2Measurement precision
If the vibration detecting sensor is provided in the cradle to detect abnormal vibrations, then the vibration detection capability is improved, but the sensor itself is damaged by the abnormal vibration it detects
Solution Approach 1:
The vibration detecting sensor is placed on the unit frame rather than directly on the cradle. The unit frame serves as an intermediary that transmits vibration information from the cradle to the sensor, allowing the sensor to detect abnormal vibrations without being directly exposed to the intense mechanical stresses and impacts of the cradle's abnormal vibrations.
Solution Approach 2:
The vibration detection function is extracted from the cradle structure and placed on the unit frame. This separates the sensing function from the mechanically stressed cradle, allowing the sensor to operate in a more stable environment while still detecting cradle vibrations through the frame's structural transmission.
3Ease of operation
If a long signal wire is used to connect the vibration detecting sensor to the control board, then the installation flexibility is improved, but the signal processing time is delayed
Solution Approach 1:
The long signal wire connection is replaced with a wireless communication system between the vibration detecting sensor and the control board. This eliminates the signal transmission delay caused by long wires while maintaining installation flexibility, as the sensor can communicate vibration detection signals without physical wire constraints.
