Rotating Watercraft Support Frame for Hull Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing personal watercraft support devices lack even weight distribution, securement mechanisms, and adjustable features, making it difficult and unsafe to access all areas of the watercraft for repairs and maintenance, often requiring multiple individuals or machinery and risking damage to the watercraft.
Innovation Solution
A personal watercraft rotisserie with a lower and upper frame system, including rotatable lateral members and a locking mechanism, providing secure and adjustable support to allow for safe access to all areas of the watercraft by rotating it to various angles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a crane or similar device is used to support the personal watercraft in an upright, raised position, then the personal watercraft can be accessed from beneath, but the individual experiences fatigue and strain due to the awkward angle required to access the lower hull from below
Solution Approach 1:
The rotisserie enables dynamic positioning of the personal watercraft by allowing it to be rotated to various angles (including upside-down and tilted positions) while securely supported. This dynamic capability eliminates the need for fixed awkward viewing angles, allowing the individual to access all areas of the personal watercraft in comfortable positions without fatigue or strain.
2Reliability
If existing personal watercraft support devices are used, then support is provided, but they lack even weight distribution and securement mechanisms, making them more prone to failure and less safe
Solution Approach 1:
The support system is segmented into multiple independent components: an upper frame with roller supports for the personal watercraft, a lower frame with caster wheels for mobility, and a rotisserie mechanism with locking capability. This segmentation allows each component to perform its specific function optimally while distributing the load and risk across multiple elements, enhancing overall reliability and reducing failure risk.
Solution Approach 2:
The rotisserie mechanism changes the rotational parameter of the personal watercraft support system, enabling adjustment to various angular positions. This parameter change capability allows the system to adapt to different maintenance scenarios while maintaining secure support, thereby improving reliability and reducing the risk of failure through versatile, controlled positioning.
3Ease of operation
If the personal watercraft is supported in a fixed position, then stability is provided, but it is difficult to access all areas including the lower hull for repairs and maintenance
Solution Approach 1:
The rotisserie transforms the static support position into a dynamic, adjustable configuration. The personal watercraft can be rotated to various angles (upside-down, tilted, or upright positions) while maintaining stable support through the locking mechanism. This dynamic positioning capability provides easy access to all areas including the lower hull while preserving stability through controlled, lockable positions.
4Ease of operation
If multiple individuals or machine assistance are used to move or position the personal watercraft, then the personal watercraft can be positioned, but the device complexity and cost increase
Solution Approach 1:
The rotisserie system enables a single individual to independently position and secure the personal watercraft without requiring multiple people or complex external machinery. The integrated design combines mobility (caster wheels), rotation (rotisserie mechanism), and securing (locking mechanism and straps) into one self-sufficient device that simplifies the positioning task while reducing overall system complexity.

AI summary
A personal watercraft rotisserie includes a lower frame having a pair of longitudinal members and a pair of lateral members, a support structure affixed to each lateral member of the lower frame, and an upper frame having a pair of longitudinal members and a pair of lateral members. Each lateral member of the upper frame is rotatably coupled to the support structures, such that the upper frame is rotatable about its longitudinal axis. The upper frame supports a personal watercraft which can be adjustably secured thereto via straps or other fasteners. A locking mechanism is configured to selectively secure the upper frame in a fixed position relative to the lower frame. In this way, an individual can support a personal watercraft in a desired rotational position to easily access the upper and lower hull for maintenance or repairs.
