Rotatable SUP Support Post with Spring Return
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing stand-up paddle board (SUP) seats lack stability, flexibility, and ease of adjustment, with most offering only two positions and requiring complex maneuvers for use and storage, posing safety risks and limiting user comfort.
Innovation Solution
A multi-position, adjustable, board-mounted user-support device with a base, rotatable support post, and spring component that allows for various angular positions, including sitting, leaning, and stowed configurations, using a telescopic portion and dual-position seat attachment for enhanced stability and convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a free-standing seat is used, then the seat can be easily removed and folded down, but it lacks stability and can be knocked over during use
Solution Approach 1:
The seat is divided into two functional parts: a stable base that remains permanently mounted on the SUP board, and a removable post assembly that can be detached and folded. This segmentation allows the base to provide stability while the post assembly maintains ease of operation.
Solution Approach 2:
The invention merges the stable base structure with the removable post assembly through a locking mechanism. When assembled, the post locks into the base to form a unified stable structure, while the base alone remains stable even when the post is removed or folded down.
2Stability of the object's composition
If a lock-in type seat is used, then the seat appears sturdy in upright position, but it is extremely difficult to place in seating position or remove and lay flat
Solution Approach 1:
The locking mechanism is extracted from being permanent and integrated, making it removable and user-operable. The post assembly can be easily detached from the base by releasing the lock, allowing simple positioning and removal without complex maneuvers.
Solution Approach 2:
The seat transitions from a static lock-in design to a dynamic system where the post can be easily locked and unlocked. The locking mechanism allows the post to be quickly positioned in upright configuration or removed and folded flat with minimal effort.
3Device complexity
If a seat with only two positions is used, then the structure is simple, but it lacks flexibility to adjust to user needs
Solution Approach 1:
The post assembly is designed to be dynamically adjustable, allowing it to be positioned at multiple angles and heights. The telescopic sections enable continuous adjustment rather than fixed positions, providing flexibility while maintaining relatively simple construction.
Solution Approach 2:
The adjustable post assembly serves multiple functions: it can be positioned for sitting, leaning, or completely removed and folded for storage. This multi-functionality is achieved through telescopic sections and adjustable angles without significantly increasing structural complexity.
4Ease of operation
If the post is rotated to stowed position over the rear of the board, then it clears the user's way, but the spring component must maintain return force to enable easy rotation back
Solution Approach 1:
The spring component acts as a counterbalancing force mechanism. When the post is rotated to the stowed position, the spring stores potential energy. When released, this stored energy provides the return force needed to rotate the post back to the upright position, reducing the effort required by the user.
Solution Approach 2:
The spring-loaded mechanism enables the post to return to its working position automatically without requiring the user to manually force it back. The spring component performs the work of returning the post, making the system self-service and improving ease of operation.
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 device provides stable, adjustable support for SUP users, allowing easy switching between positions while on the water and a compact stowed configuration, enhancing safety and comfort by eliminating the need for complex maneuvers and reducing the risk of injury.
Implementation Method 1
a spring component mounted to and between the base and the support post. The spring component is configured to maintain a return force on the support post when the support post is rotated away from the base toward a rear portion of the base and the rear of the stand-up paddle board

AI summary
A device for providing user-support on a stand-up paddle board (SUP) includes a support post having a user-support pad mounted to its upper end portion and a horizontal rotation axle around which the support post is rotatable to a position for use, and to a stored position. The device is configured to be mounted to the SUP with the horizontal rotation axle positioned transversely to a length of the SUP. The device includes a spring component returnably connected to the support post via the horizontal rotation axle, configured to impose a return force on the support post in the stored position.
