Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for boat lifts that can accommodate large vessels and be transported on highways without special permits, while also addressing issues of corrosion and fouling in saltwater environments, and providing a means to lift boats out of the water for maintenance and storage.
Innovation Solution
A modular boat lift system with high-density polyethylene flotation tanks and connecting guide constructs that allow for the assembly of wide and long boat lifts on-site, using pumps to evacuate water and maintain stability against horizontal forces, enabling the lift of large boats out of the water for maintenance and storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If boat lifts are made large to accommodate bigger vessels, then the lifting capacity increases, but the transportation width exceeds highway limits requiring special permits
Solution Approach 1:
The boat lift is divided into multiple modular sections that can be assembled on-site. Each module has a manageable width for highway transportation, but when combined, they create a large-capacity lift capable of accommodating bigger vessels. The modular design allows the system to scale in capacity without exceeding transportation constraints.
2Ease of manufacture
If boats are stored in saltwater environments, then storage space is utilized, but corrosion and fouling occur rapidly
Solution Approach 1:
The system addresses the harmful effects of saltwater by providing a mechanical solution (boat lift) that completely removes boats from the corrosive environment. By lifting boats out of the water, the system converts the problem of saltwater exposure into an opportunity for protective storage, eliminating corrosion and fouling while maintaining efficient use of water storage space.
3Length of moving object
If modular boat lifts are assembled on-site to achieve substantial width, then transportation constraints are avoided, but assembly complexity increases
Solution Approach 1:
The boat lift is divided into standardized modular sections with uniform connection interfaces. This segmentation allows for simplified on-site assembly through repetitive connection operations rather than complex custom fabrication. Each module is designed to be transportable on standard highways, and the modular nature reduces assembly complexity through standardization.
4Speed
If pumps are used to evacuate water from flotation tanks, then boat lift rises to lift boats, but energy consumption increases
Solution Approach 1:
The pump system operates periodically rather than continuously, evacuating water from flotation tanks only when lifting is required. The system can maintain position with minimal energy input once lifted, and lowers boats by allowing controlled water influx. This periodic operation significantly reduces overall energy consumption compared to continuous pumping, while still achieving the required lifting speed when needed.

Function Achieved in This Case
The modular boat lift system allows for the transportation and assembly of wide and long boat lifts without special permits, effectively preventing corrosion and fouling by keeping boats out of the water, and provides stable operation against wind and wave forces, facilitating easy maintenance and storage.
Implementation Method 1
one or more pumps that evacuate water from a first flotation tank construct and a second flotation tank construct to create flotation of the boat lift

AI summary
A boat lift has one or more pumps that evacuate water from a first flotation tank construct and a second flotation tank construct to create flotation of the boat lift. Modular boat lifts may be constructed according to the invention that have substantial size but are transportable by truck for construction on site.
