Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for erecting wind turbine towers using preassembled ladder segments face interference issues with assembly scaffolding, requiring careful handling to avoid damage and complicating the assembly process.
Innovation Solution
A method involving preassembling supply structural segments within tower segments, allowing them to be positioned and connected without protruding, enabling safe and efficient stacking of tower segments while facilitating the simultaneous assembly of the supply structure along the tower's height.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If ladder segments are preassembled in tower segments in a slightly movable way to facilitate linking, then the ease of operation is improved, but the reliability deteriorates due to interference with assembly scaffolding and risk of damage
Solution Approach 1:
The ladder segments are preassembled in a slightly movable way within the tower segments before the actual tower assembly takes place. This preliminary arrangement allows the ladder segments to be positioned and linked together more easily during tower construction, while still being protected from damage by the movable connection that prevents interference with assembly scaffolding.
Solution Approach 2:
The ladder segments are connected in a slightly movable way rather than being rigidly fixed. This dynamic connection allows the ladder segments to adapt during assembly, avoiding interference with assembly scaffolding and reducing the risk of damage, while still maintaining the ability to be firmly linked once positioned.
2Productivity
If ladder segments are preassembled in tower segments, then the productivity is improved by parallel assembly, but the device complexity increases due to coordination requirements
Solution Approach 1:
The assembly of the tower segments and the ladder segments is merged into a single coordinated process. The ladder segments are preassembled within the tower segments themselves, allowing both structures to be constructed simultaneously in parallel, thereby increasing productivity without requiring separate assembly operations.
Solution Approach 2:
The ladder segments are preassembled in a slightly movable way within the tower segments before final tower assembly. This preliminary preparation simplifies the coordination requirements during actual assembly, as the ladder segments are already positioned and linked, reducing the complexity of coordinating the two assembly processes.
3Ease of operation
If supply structural segments are arranged to not protrude from tower segments, then the ease of operation is improved by preventing interference, but the length of the supply structure is reduced in the assembly position
Solution Approach 1:
The supply structural segments are nested within the tower segments in the assembly position, arranged so they do not protrude from the tower segment boundaries. This nesting allows the tower segments to be stacked without interference while the supply structure maintains its full length capability when deployed to the use position.
Solution Approach 2:
The supply structural segments are arranged dynamically, positioned to not protrude during assembly for ease of operation, but capable of extending to their full length when moved to the use position. This dynamic arrangement resolves the contradiction between assembly ease and structural length requirements.

AI summary
A tower segment for at least a section of a tower includes a tower segment defining an interior, a longitudinal axis, and a wall, and a supply structural segment preassembled in the interior of the tower segment extending along a the longitudinal axis of the tower segment. The supply structural segment is movable relative to the tower segment and connected to the wall of the tower segment so that the supply structural segment can be moved at least from an assembly position to a connecting position. Other tower, tower segment, support structure, support structural segment, and methods of erection of same use at least a tower segment of a tower.
