Rotating Mast-Boom Base Structure for Lower Mast Load
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing marine vessels require strong masts to support booms due to the direct connection of the boom's proximal portion to the mast, leading to increased structural demands.
Innovation Solution
A base is connected to the lower end of the mast and proximal portion of the boom, allowing them to rotate integrally in a plane perpendicular to the hull, reducing the load on the mast and thus the required strength.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the proximal portion of the boom is connected to the lower end portion of the mast, then the sail, mast, and boom can integrally rotate in the plane perpendicular to the upward-downward direction, but the mast requires relatively high strength to support the boom load
Solution Approach 1:
The invention divides the support structure into separate components: the mast supports the sail vertically, while the boom is supported by a separate base structure rather than being directly connected to the mast. This segmentation allows each component to be optimized for its specific function, reducing the strength requirements for the mast while maintaining the ability to rotate the entire assembly.
Solution Approach 2:
The base structure acts as an intermediary element between the mast and the boom. Instead of directly connecting the boom to the mast, the base provides a separate support point for the boom while allowing the mast to remain independent. This intermediary structure enables integral rotation without transferring boom loads to the mast, thereby reducing mast strength requirements.
2Strength
If the mast is made stronger to support the boom load, then the mast can handle the structural demands, but the overall device complexity and potential obstructions for passengers increase
Solution Approach 1:
By segmenting the support functions into separate structures (mast for sail support, base for boom support), the invention avoids the need to make the mast stronger. This segmentation simplifies the overall structure and reduces complexity compared to a single reinforced mast design.
Solution Approach 2:
The base structure serves as an intermediary that handles the boom support function separately from the mast. This separation allows for simpler, more optimized structures for each component, reducing overall device complexity while maintaining structural integrity.
