Elevator-Carried Service Platform for Flexible Tower Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional platform systems in buildings, especially wind turbine towers, are inflexible, complex, and expensive, limiting maintenance to predefined positions and requiring multiple fixed installations.
Innovation Solution
A platform positioning system with a cabin-attached platform that can be releasably attached to both the cabin and the wall segment via first and second attachment means, allowing movement and attachment at any desired location using pins, magnetic, or clamp connections, and controlled by a unit to ensure safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional fixed platforms are installed at predetermined positions, then safety requirements are met and maintenance can be performed, but the system becomes complex and expensive, and maintenance is limited to predefined positions only
Solution Approach 1:
The platform is transformed from a static fixed installation to a dynamic movable structure that can be transported by the elevator cabin to different positions. The platform includes attachment means that enable it to be coupled to the cabin during transport and then detached to work independently at the destination position, allowing the same platform to serve multiple locations sequentially rather than requiring simultaneous fixed installations at all possible positions
Solution Approach 2:
The elevator cabin serves dual functions: it acts as both the transportation vehicle for the platform and as a temporary support structure during positioning operations. The platform itself is designed to be universally applicable at any position along the elevator track, eliminating the need for position-specific custom installations and reducing overall system complexity
2Adaptability or versatility
If multiple fixed platforms are installed at different positions, then maintenance can be performed at various locations, but the cost and complexity of installation increase significantly
Solution Approach 1:
Instead of installing multiple static platforms simultaneously at different heights, the system uses a single dynamic platform that is transported by the elevator to each required position sequentially. This eliminates the need for multiple parallel installation projects and reduces material costs, as the same platform structure is reused across different locations rather than duplicating the entire platform assembly at each position
Solution Approach 2:
The platform is extracted from the fixed installation context and transformed into a portable, transportable unit. By separating the platform from permanent wall mounting and coupling it temporarily to the moving elevator cabin, the system enables single-platform multi-location deployment, significantly reducing manufacturing and installation expenses compared to traditional multi-platform fixed installations
3Adaptability or versatility
If the platform is permanently attached to the wall, then stable support is provided, but the platform cannot be repositioned to different locations for maintenance work
Solution Approach 1:
The attachment system transitions from a permanent static connection to a dynamic controllable connection. The platform includes attachment means that can be engaged or disengaged from the wall structure as needed, allowing the platform to be securely fixed when working at a position and easily relocated when maintenance is complete or new positions are required, maintaining stability during use while enabling repositioning between operations
Solution Approach 2:
The elevator cabin acts as an intermediary mechanism between the platform and the wall structure during the positioning process. The platform is first coupled to the moving cabin, transported to the target position, and then attached to the wall independently. This intermediary transport method enables reliable positioning without requiring direct permanent attachment, bridging the gap between mobility and stability requirements
