Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing textile machines with sensors cannot detect the position or movement of components between operational and non-operational states, leading to potential collisions during maintenance and impaired spinning processes.
Innovation Solution
Incorporating an inertial measuring unit with MEMS elements, such as yaw rate sensors and gyroscopes, to detect changes in position and movement between layers, allowing for precise monitoring of component positions and movements, including rotations and linear accelerations, and integrating these measurements to determine the component's position at any time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional sensors are used to detect component positions, then end positions can be detected, but positions and movements between end positions cannot be detected
Solution Approach 1:
The patent replaces traditional mechanical sensors (which can only detect end positions) with an inertial measuring unit containing MEMS elements. This inertial sensor system measures acceleration, velocity, and position changes through physical principles (acceleration integration), enabling continuous position tracking between end positions rather than discrete detection.
Solution Approach 2:
The invention changes the detection parameter from discrete position states (end positions only) to continuous motion parameters (acceleration, velocity, displacement). By measuring acceleration and integrating it over time, the system derives continuous position information, transforming the detection capability from static to dynamic.
2Ease of repair
If components are moved between layers for maintenance access, then maintenance facilities can access spinning stations, but collisions between components and maintenance devices may occur
Solution Approach 1:
The system implements continuous feedback by using the inertial measuring unit to monitor component position in real-time. When a component is moved to a position that may obstruct maintenance facilities, the system detects this through acceleration measurements and provides feedback signals to control systems, enabling preventive action before collisions occur.
Solution Approach 2:
The inertial sensor detects position changes before they result in collision hazards. By continuously monitoring acceleration and calculating position, the system can predict when a component will enter a maintenance facility's path and trigger preliminary actions (such as stopping the maintenance device or returning the component to a safe position) before the collision occurs.
3Productivity
If components remain in operational positions, then spinning processes continue, but maintenance access is blocked
Solution Approach 1:
The system enables dynamic position control of components by using inertial measurement to track movement between operational and maintenance positions. This allows the component to be moved to maintenance positions only when and where needed, rather than remaining statically in either operational or maintenance position, thus dynamically balancing productivity and maintainability.
