Automated Flag Raising System for Waterski Boats
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Boat operators engaged in water sports face challenges in manually maintaining a visible flag while attending to multiple time-sensitive responsibilities, as existing systems require manual deployment and constant holding of the flag, hindering their ability to perform other duties.
Innovation Solution
An automated warning system using a receiver/controller, actuator, and mechanical linkage that raises and lowers a flag based on discrete signals, allowing observers to control the flag's position without manual intervention, incorporating a transmitter, relays, and a strobe light for enhanced visibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the observer manually deploys and holds the ski flag in the raised position, then the flag remains visible to other boats as required by regulations, but the observer's ability to perform other time-sensitive responsibilities is hindered
Solution Approach 1:
The system allows the flag to service itself through automated actuation. The linear actuator automatically raises and lowers the flag based on transmitter signals, eliminating the need for continuous manual intervention by the observer while ensuring regulatory compliance for flag visibility
Solution Approach 2:
The patent replaces the manual mechanical system (observer physically raising and holding the flag) with an automated electromechanical system. The linear actuator converts electrical signals into mechanical motion to automatically position the flag, substituting human physical effort with an automated device
2Reliability
If the observer continuously monitors and manually adjusts the flag position, then regulatory compliance is maintained, but time for other safety responsibilities is reduced
Solution Approach 1:
The system performs the flag positioning action in advance and maintains it automatically. The linear actuator raises the flag before needed and keeps it positioned without requiring continuous observer attention, allowing the observer to focus on other safety duties while compliance is maintained
Solution Approach 2:
The system incorporates feedback through limit switches that detect when the flag reaches its raised or lowered position. This feedback mechanism automatically controls the actuator to stop at the correct positions and return to the stowed position when needed, ensuring compliance without continuous manual monitoring
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 observers to focus on other responsibilities while ensuring the flag remains visible or hidden as needed, complying with regulations and improving safety and efficiency during water sports.
Implementation Method 1
an actuator (e.g., a linear actuator) that raises and/or lowers the flag holder
Implementation Method 2
the warning system may further include a light (e.g., a strobe light) positioned atop the system

AI summary
There is provided an automated warning system which includes a receiver/controller, an actuator, one or more relays electrically connected to both the receiver and the linear actuator, a flag holder and a mechanical linkage connecting the linear actuator to the flag holder such that movement of the linear actuator causes the flag holder to move between raised and lowered positions.
