Rotating Dinghy Support Arrangement for Upright Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions for lifting and supporting a dinghy on a carrier boat are cumbersome and require manual assistance to position the dinghy upright, limiting ease and speed of operation.
Innovation Solution
A support arrangement featuring rotatable carrying members with rings and telescoping rod members that can be adjusted to securely hold conical pontoon ends, allowing for easy rotation from a horizontal to an upright position using friction and weight-induced deflation, with optional attachment to a swim platform or carrier boat.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a dinghy is lifted out of the water and positioned in a securing arrangement without assistance, then the dinghy can be supported in an upright position, but it is difficult to bring the dinghy into this position
Solution Approach 1:
The carrying members are designed to be rotatable between a horizontal orientation (when the dinghy is in the water) and an upright orientation (when the dinghy is stored onboard). This dynamic capability allows the support arrangement to adapt to different operational states, making it easy to position the dinghy by simply rotating the carrying members rather than manually lifting and positioning the entire dinghy.
Solution Approach 2:
The support arrangement enables the dinghy to be supported and positioned automatically through the rotation of the carrying members. Once the dinghy is engaged with the carrying members in horizontal orientation, rotating the members to upright orientation automatically positions the dinghy in its storage position without requiring additional manual assistance.
2Object-affected harmful factors
If the dinghy is lifted out of the water and stored onboard, then more space is given to surrounding boats and the dinghy is protected from damage, but the operation becomes cumbersome and time-consuming
Solution Approach 1:
The rotatable carrying members enable a quick transition between horizontal and upright orientations, significantly reducing the time required to lift and store the dinghy compared to traditional manual lifting methods.
Solution Approach 2:
The support arrangement performs the lifting and positioning functions automatically through the rotation mechanism, eliminating the need for multiple persons or complex manual operations, thus reducing both time and effort required for the operation.
3Adaptability or versatility
If the carrying members are designed to receive conical pontoon ends, then various dinghy sizes and shapes can be accommodated, but the structure becomes more complex
Solution Approach 1:
The carrying members are designed with conical receiving surfaces that match the conical pontoon ends of the dinghy. This geometric parameter matching allows the same carrying member design to accommodate various dinghy sizes and shapes by simply rotating the members to the appropriate orientation, without requiring complex adjustable mechanisms.
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
Enables quick and simple lifting of a dinghy into an upright storage position, reducing manual effort and space requirements, while accommodating a range of dinghy sizes and shapes, and allowing easy deployment and stowage.
Implementation Method 1
The rod members may be rotationally locked to each other... A friction arrangement may be provided between the rod members and the tubular member that reduces the play between the parts and increases the friction between the parts
Implementation Method 2
when the conical pontoon ends of the dinghy are received in the rings and the dinghy adopts the upright orientation, the conical pontoon ends are fastened in the rings due to friction and/or a slight local deflation of the pontoon ends imposed by the weight of the dinghy
