Retractable Boat Hammock Support System Bow Obstruction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a retractable hammock system on boats that allows for safe and convenient use of a hammock while ensuring the hammock does not obstruct the bow of the boat and provides a mechanism to prevent engine operation when the hammock is extended, enhancing safety and usability.
Innovation Solution
A retractable hammock support system with a tubular housing and sliding tubular member, secured wheels, locking mechanisms, and a switch that prevents engine start when the hammock is extended, ensuring the hammock can be safely deployed and stowed without obstructing the boat's bow, and includes a hook for securing a hammock with a chain for adjustable height.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the hammock is extended for use, then the hammock provides leisure functionality, but the hammock may obstruct the bow of the boat
Solution Approach 1:
The hammock support system employs a retractable tubular member that can dynamically extend and retract along a longitudinal axis. When extended, the hammock provides leisure functionality; when retracted, the member withdraws into the housing to clear the bow area, eliminating obstruction. This dynamic transformation allows the system to adapt between functional states without permanent occupation of space.
2Adaptability or versatility
If the hammock is extended, then the hammock can be used for leisure, but engine operation may be accidentally initiated
Solution Approach 1:
The system incorporates a switch that detects the extension state of the tubular member and provides feedback to the engine control system. When the member is extended, the switch prevents engine initiation; when retracted, the switch permits normal operation. This feedback mechanism ensures safety by making engine operation dependent on the hammock's retracted position, eliminating the risk of accidental engine startup during hammock use.
3Adaptability or versatility
If the tubular member is made extendable for hammock deployment, then the hammock can be fully utilized, but the mechanism becomes more complex
Solution Approach 1:
The system divides the support structure into distinct segments: a fixed housing attached to the boat, a retractable tubular member that extends along the longitudinal axis, and a hook assembly at the distal end. This segmentation allows the complex functionality to be achieved through modular components, where the tubular member's linear extension and retraction provide the necessary deployment capability without requiring overly complex mechanical systems.

AI summary
A retractable hammock support system includes a tubular housing and a first plurality of wheels. The first plurality of wheels are secured to the housing. The system includes a tubular member having a first portion disposed within the housing and a second portion disposed outside the housing. The member is slidable into or out from the housing. In a retracted position, the second portion has a first length. In an extended position, the second portion has a second length. The first length is shorter than the second length. The system includes a handle disposed on the member. The handle is disposed on the second portion of the member. The first plurality of wheels are disposed within an interior space of the member. The first plurality of wheels are configured to contact a first internal surface of the member.
