Solution Overview
Problem
Existing platform assemblies for boats, such as telescopic gangways, have a significant overlap between movable and fixed parts at maximum extension, limiting the usable surface area and leading to inefficient space utilization, especially in applications where length extension is comparable to or less than width.
Innovation Solution
A movable platform assembly with a horizontal translation system comprising rotatable main arms and sliders, allowing for a translation/size ratio close to 1, reducing overlap and enabling greater surface usage, and combining with additional movements for increased versatility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If telescopic gangway systems are used with significant overlap between movable and fixed parts, then structural stability is ensured, but the usable surface area is significantly reduced
Solution Approach 1:
The translation system is divided into multiple functional components: main arms for translational movement, secondary arms for stabilizing movement, and corresponding sliders and guides. This segmentation allows each component to perform its specific function optimally, achieving both stability and extended surface area utilization.
Solution Approach 2:
The system transitions from simple linear telescopic movement to a multi-dimensional movement pattern involving both longitudinal translation (via main arms) and transverse stabilization (via secondary arms). This dimensional expansion allows the platform to achieve stability through distributed support points rather than overlapping structures.
2Area of moving object
If translation/size ratio is increased close to 1, then surface utilization is improved, but the risk of interference with additional movements increases
Solution Approach 1:
The translation system is divided into multiple functional components: main arms for translational movement, secondary arms for stabilizing movement, and corresponding sliders and guides. This segmentation allows each component to perform its specific function optimally, achieving both stability and extended surface area utilization.
Solution Approach 2:
The secondary arms act as intermediary elements between the main translational movement and the platform, providing stabilizing movement that mediates the interaction between the extended platform and the boat structure. This intermediary mechanism reduces direct interference while enabling full surface utilization.
3Area of moving object
If overlap between parts is reduced, then space efficiency is improved, but the complexity of ensuring stability decreases
Solution Approach 1:
The translation system is divided into multiple functional components: main arms for translational movement, secondary arms for stabilizing movement, and corresponding sliders and guides. This segmentation allows each component to perform its specific function optimally, achieving both stability and extended surface area utilization.
Solution Approach 2:
The secondary arms serve multiple functions: they provide stabilizing movement, support the platform during extension, and work in conjunction with the main arms to maintain structural integrity. This multi-functionality reduces the need for separate stability mechanisms, managing complexity while achieving space efficiency.
