Circular Elevator Cabin with Nested Hollow Uprights for Ships
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing elevator cabins in watercraft with multiple bridges are bulky due to large mechanical components, compromising their aesthetic integration with luxurious furnishings and occupying excessive space.
Innovation Solution
A free-standing elevator cabin with a circular structure, featuring hollow uprights and a lift platform with a circular section, where the structural uprights are housed inside the platform's uprights, allowing for compact design and easy integration with luxurious aesthetics, using hydraulic drive means for vertical movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If traditional elevator cabin structures are used, then mechanical components can be housed, but the cabin occupies excessive space and has large bulk
Solution Approach 1:
The structural uprights are housed inside the hollow uprights of the lift platform, creating a nested configuration where one structural element is contained within another. This nesting arrangement significantly reduces the overall bulk and volume of the elevator cabin while providing adequate space for mechanical components and structural support.
2Adaptability or versatility
If traditional elevator cabin structures are used, then mechanical support is provided, but the design does not integrate with luxurious aesthetics
Solution Approach 1:
The nested configuration of structural uprights within hollow platform uprights allows the mechanical structure to be concealed within the aesthetic exterior. This enables the elevator cabin to integrate seamlessly with luxurious interior designs while maintaining adequate structural support and mechanical component housing capacity.
3Volume of moving object
If compact design is implemented, then space is minimized, but mechanical components may be compromised
Solution Approach 1:
The nested structure provides optimized internal spacing that accommodates all necessary mechanical components within the compact cabin volume. The hollow uprights of the lift platform contain the structural uprights, creating efficient use of space while maintaining adequate room for hydraulic cylinders, control mechanisms, and maintenance access, thereby ensuring reliable operation despite the reduced overall size.
