Pivotable Trailer Boat Covering Spindle System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing boat covering devices are not easily movable relative to a trailer, making them ineffective for protecting boats during transportation.
Innovation Solution
A trailer-based system with pivotable and laterally movable supports and an adjustable spindle that allows a single person to quickly position and retract a covering over a boat, utilizing a frame with wheels, supports, and a spindle for easy deployment and storage of the covering.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a boat covering device is made stationary or fixed relative to a trailer, then the device provides stable support for the covering, but the device cannot be easily moved or repositioned to cover the boat effectively during transportation
Solution Approach 1:
The patent applies the dynamics principle by making the supports pivotable and laterally movable relative to the trailer frame. The supports can rotate about vertical axes and move laterally to position the spindle over the boat, enabling the device to transition from a fixed configuration to a dynamic, repositionable configuration that can effectively cover the boat during transportation while maintaining stability when in use
2Ease of operation
If a covering device is designed to be easily movable and repositionable, then the device can effectively protect the boat during transportation, but the device becomes more complex in structure
Solution Approach 1:
The patent applies segmentation by dividing the covering device into separate functional components: a trailer frame, pivotable supports, and a spindle assembly. Each component performs a specific function and can move independently, which simplifies the overall design while enabling complex repositioning capabilities. The supports are separated from the frame and can rotate independently, reducing structural complexity compared to a fully integrated rigid structure
Solution Approach 2:
The patent applies multi-functionality by designing the supports to perform multiple functions: they provide structural support for the spindle, enable lateral movement for positioning, and allow rotation for alignment. This multi-functional design reduces the need for additional separate components, thereby reducing overall device complexity while maintaining ease of operation
3Loss of time
If a single person is to quickly position and retract the covering, then the operation time is reduced, but the device requires simpler operation mechanisms
Solution Approach 1:
The dynamic pivotable supports enable quick repositioning of the spindle over the boat by a single person, significantly reducing the time required to cover and uncover the boat. The lateral movement and rotation capabilities allow rapid deployment without requiring complex automated mechanisms, as the system can be manually operated efficiently

AI summary
A trailer and boat covering combination system includes a trailer including a frame having a front end, a first lateral member and a second lateral member. A plurality of wheels is rotatably attached to and extends downwardly from the frame. A pair of supports is attached to the trailer such that each of the first and second lateral members has one of the supports attached thereto. A spindle is attached to and extends between the supports. The supports are pivotable forwardly and rearwardly relative to the trailer such that the spindle is movable over the trailer. The supports are biased toward an upright position. A covering is positioned on the spindle and is unwound off of the spindle to cover a boat positioned on the trailer. The covering is wound back onto the spindle to store the covering on the spindle.
