Rotating Paddleboard Rack for Secure Boat Rod Holder Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing boat racks are unable to securely transport and store large paddleboards, posing tripping hazards and risking damage due to unsecured storage on boat floors.
Innovation Solution
A portable water sport board rack with a rotational unit and elongated rod that can accommodate large boards, allowing 360-degree rotation and secure attachment to boat rod holders without special mounting hardware, featuring a J-shaped board holder with retention straps for secure positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing boat racks are used, then the racks can transport small water sport boards, but they cannot support large paddle boards
Solution Approach 1:
The rack structure is designed with adjustable parameters including telescopic arms that can extend and retract, and rotating joints that allow angular adjustment. These parameter changes enable the rack to adapt to different board sizes while maintaining secure support capability through controlled structural transformations.
Solution Approach 2:
The rack is divided into multiple independent segments including separate arms, rotating joints, and adjustable components. This segmentation allows each part to be independently positioned and configured to accommodate various board dimensions while maintaining overall structural integrity and support reliability.
2Area of stationary object
If boards are stored on the floor or unsecured spaces, then storage space is available, but tripping hazards and board damage occur
Solution Approach 1:
The rack serves as an intermediary structure between the boat floor and the paddle board. It provides a dedicated secure mounting interface that elevates boards off the floor space while preventing contact with occupants, thereby eliminating tripping hazards and board damage risks without compromising storage availability.
Solution Approach 2:
The rack design includes self-adjusting features where the structure automatically adapts to the board's position and dimensions through spring-loaded arms and rotating joints. This self-service capability ensures boards are securely held in place without requiring constant manual adjustment or external intervention.
3Reliability
If a portable rack is designed for large boards, then board support capability is improved, but the rack becomes heavier and less portable
Solution Approach 1:
The rack utilizes thin-walled tubular structures and flexible joint mechanisms that provide high strength-to-weight ratios. The arms are constructed with hollow cylindrical sections that maintain structural integrity for supporting large boards while minimizing material usage and overall weight for portability.
Solution Approach 2:
The rack incorporates dynamic elements including rotating joints and telescopic arms that allow the structure to adapt its configuration. This dynamic design enables the rack to maintain support capability for various board sizes while using minimal material, thereby reducing weight without compromising reliability.
4Reliability
If special mounting hardware is used, then secure attachment to boat is achieved, but the rack cannot be used interchangeably with different boat types
Solution Approach 1:
The rack is designed with universal mounting features that can interface with various boat types through standardized rod holder adaptations. The rotating arm mechanism allows the rack to accommodate different mounting positions and angles found across various boat designs, providing both secure attachment and broad compatibility without requiring boat-specific custom hardware.

AI summary
A portable water sport board rack includes a board holder that has an elongated back section, a curved bottom section, and a lip section that define a channel for receiving a large water sport board such as a paddle board. The bottom end of the board holder and an elongated rod are secured onto the top and bottom surfaces of a rotational unit which can rotate 360 degrees about a vertical axis. The elongated rod includes a shape and size to be removably inserted within the rod holder of a boat.
