Solution Overview
Problem
Existing devices for transporting plastic preforms are inflexible and prone to errors due to fixed parameterization, which can lead to issues like sticking or misalignment caused by temperature changes, requiring frequent adjustments and potentially resulting in operational failures.
Innovation Solution
A method and device that utilize two measuring devices to continuously monitor the occupancy state of plastic preforms and adjust manipulated variables such as feed speed, roller speed, and distance between rollers, allowing for adaptive control to handle both gradual and short-term changes, including the use of a self-learning control system that reacts to environmental conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If fixed parameterization is used for transport speed, then device complexity is reduced, but adaptability to environmental changes deteriorates
Solution Approach 1:
The control system transitions from static fixed parameterization to dynamic adaptation by continuously measuring occupancy states and automatically adjusting transport parameters. The system adapts its speed and operational parameters in real-time based on measured occupancy values, enabling responsiveness to environmental changes while maintaining manageable complexity through automated feedback control.
Solution Approach 2:
The system performs self-adjustment by automatically regulating its own transport parameters based on occupancy measurements. The control system monitors the occupancy state and autonomously modifies transport speed and other parameters without external intervention, allowing the device to self-adapt to changing conditions such as temperature variations and occupancy fluctuations.
2Adaptability or versatility
If manual adjustment of parameters is implemented, then adaptability to changes improves, but loss of time increases
Solution Approach 1:
The system implements continuous feedback control by measuring occupancy states with measuring devices and automatically adjusting transport parameters based on these measurements. The control system receives real-time occupancy data and responds by modifying transport speed and other parameters, eliminating the need for manual adjustments and reducing time loss while maintaining high adaptability to occupancy changes.
Solution Approach 2:
The manual mechanical adjustment process is replaced with an automated electronic control system. The system uses electronic sensors to measure occupancy states and electronic actuators to adjust transport parameters, substituting the time-consuming manual adjustment process with rapid automated control that responds instantly to occupancy changes.
3Device complexity
If fixed speed transport is used, then device complexity is reduced, but reliability under varying conditions deteriorates
Solution Approach 1:
The transport system transitions from fixed speed to dynamic speed adjustment based on occupancy measurements. The control system automatically adapts transport parameters to current occupancy conditions, preventing sticking and misalignment issues that occur with fixed parameterization. This dynamic adaptation maintains reliability across varying environmental conditions while keeping the control mechanism manageable through automated feedback.
Solution Approach 2:
The system implements continuous feedback control where occupancy measurements inform real-time adjustments to transport speed and parameters. This feedback loop ensures the system responds to changing conditions such as temperature variations and occupancy fluctuations, maintaining reliable operation without requiring complex manual intervention or overly complicated control mechanisms.
