Tapered Structure Roll Control for Continuous Geometry Accuracy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current control systems for constructing tapered structures, such as wind turbine towers, face challenges in achieving substantially continuous and accurate construction due to additional degrees of freedom involved in forming tapered shapes, leading to errors and inefficiencies in manufacturing.
Innovation Solution
A control system that includes sensors providing feedback to adjust the positions of rolls and the stock material in a machine with a triple roll configuration, using rollette banks and an infeed adjustment mechanism to control the diameter and shape of the tapered structure, ensuring accurate and continuous formation through a controller that sends control signals for precise positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional control systems are used for constructing tapered structures, then the construction process can be completed, but the manufacturing precision and continuity are insufficient due to additional degrees of freedom in forming tapered shapes
Solution Approach 1:
The control system dynamically adjusts the positions of multiple rolls (including at least one bend roll and at least two guide rolls) during the construction process to accommodate the changing geometry of tapered structures. This dynamic adjustment capability enables continuous and accurate formation of tapered shapes by adapting to additional degrees of freedom in real-time
Solution Approach 2:
The control system incorporates feedback mechanisms that continuously monitor the construction process and automatically adjust roll positions and stock material positioning. This feedback loop ensures manufacturing precision by correcting deviations in tapered structure geometry during the formation process
2Manufacturing precision
If manual adjustment of machine parameters is used, then the equipment is simpler to operate, but the manufacturing precision and error reduction are insufficient
Solution Approach 1:
The control system automatically positions the stock material and adjusts roll configurations without requiring manual intervention. The system self-regulates the formation process by receiving feedback and automatically sending control signals to adjustment mechanisms, thereby achieving high manufacturing precision while reducing operational complexity
Solution Approach 2:
The system replaces manual mechanical adjustment with automated control mechanisms that use sensors and controllers to precisely position rolls and stock material. This substitution of manual operation with automated control systems enables superior manufacturing precision while simplifying the operator's role
3Manufacturing precision
If continuous adjustment of roll positions is implemented, then the manufacturing precision improves, but the device complexity increases
Solution Approach 1:
The control system serves multiple functions simultaneously: it positions rolls, positions stock material, monitors geometry, and adjusts parameters all through a single integrated system. This multi-functionality enables continuous and precise tapered structure formation without proportionally increasing device complexity

AI summary
A control system for forming a tapered structure includes a sensor providing feedback for a machine for forming a tapered structure including at least three rolls having at least one bend roll and at least two guide rolls. The guide rolls may include rollette banks having a plurality of rollettes. The machine may also include an adjustment mechanism to position at least one of the rolls, where a diameter of the tapered structure being formed is controlled by relative positions of the rolls. The machine may also include a joining element to join edges of a stock of material together as it is rolled through the rolls to form the tapered structure. The control system may also include a controller to receive feedback from the sensor and to send a control signal based on the feedback to the adjustment mechanism for positioning at least one of the rolls.
