Roller-Supported Canopy Extension for Obstruction-Free Boat Shade
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bimini tops and radar arches on boats create obstructions and design discontinuities, obstructing movement and appearance, while offering limited additional utility.
Innovation Solution
A canopy extension system with a roller mechanism and spring-biased secondary arm that unfurls and tensions a canopy in a single layer over the boat deck, supported by a radar arch or independent structure, providing expanded shade coverage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If separate front and rear pole members are used to support the canopy, then the canopy is firmly supported, but the pole members obstruct movement and create design discontinuity
Solution Approach 1:
The patent combines the radar arch structure with the bimini top support system, integrating what were previously separate components. The radar arch serves dual purposes: as a structural support for electronic equipment and as the primary support for the canopy, eliminating the need for separate obstructive pole members while maintaining canopy stability
2Strength
If multiple pole members are used to support the intermediate section of the canopy, then the canopy is firmly supported, but additional obstacles are created for boarding and loading
Solution Approach 1:
The patent removes the intermediate pole members that obstructed movement and created design discontinuity. The canopy is instead supported by extending the radar arch structure, which eliminates the need for additional obstructive poles while maintaining structural integrity and providing unobstructed access for boarding and loading
3Object-affected harmful factors
If a standard foldable bimini top is used, then shade protection is provided, but the design appears discontinuous and utility is limited
Solution Approach 1:
The patent creates a multi-functional system where the radar arch serves multiple purposes: supporting radar and electronic equipment, providing structural support for the canopy, and serving as an aesthetic design element. This integration enhances both the utility and adaptability of the system while maintaining continuous sun protection
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system eliminates obstructions and enhances design continuity by extending the canopy for greater shade coverage, improving usability and aesthetic integration with radar arches.
Implementation Method 1
a spring connected between the radar arch and the canopy arm

AI summary
A canopy extension system is cooperable with a support structure and includes a canopy arm securable pivotably to the support structure and a roller arm securable pivotably to the support structure. A roller is secured on the roller arm. A canopy is connected to the canopy arm at a distal end, is connected adjacent the support structure at a proximal end, and is connected to the roller between the distal end and the proximal end. A variation connects the canopy arm to a radar arch or the like with a spring-biased secondary canopy arm.
