Craft Mode-Transition Feedback for Water-to-Air Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The transition between water and air operations in crafts like seagliders poses challenges due to differences in controlling the craft in three dimensions, increasing cognitive load on operators and affecting the overall experience.
Innovation Solution
Implementing a user input device, display device, and control system that facilitate mode transitions with feedback mechanisms, including lever detents and dynamic display changes, to simplify operation across modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the craft operates in multiple modes (water and air), then the versatility and adaptability of the craft is improved, but the complexity of control and cognitive load on the operator increases
Solution Approach 1:
The control system is designed to provide universal control mechanisms that work across multiple operational modes (hull-borne, hydrofoil-borne, wing-borne). The same lever and display interface are used regardless of which mode the craft is in, allowing the operator to control the craft uniformly whether it is operating in water or air, thereby reducing cognitive load while maintaining versatility
2Adaptability or versatility
If the craft operates in multiple modes (water and air), then the versatility and adaptability of the craft is improved, but the ease of operation deteriorates due to differences in controlling the craft in three dimensions
Solution Approach 1:
The display device provides continuous feedback to the operator about the current operational mode and system state. Visual indicators show whether the craft is in hull-borne, hydrofoil-borne, or wing-borne mode, and the lever position feedback helps the operator understand the current configuration. This feedback mechanism makes the transition between water and air operations more intuitive and easier to manage
Solution Approach 2:
The control system segments the operational modes into distinct states (hull-borne, hydrofoil-borne, wing-borne) that are clearly indicated on the display. By segmenting the complex multi-mode operation into clearly defined states with distinct visual indicators, the operator can more easily understand and manage the craft across different dimensional regimes
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
Reduces cognitive load on operators by making the craft's operation more similar to boat handling, enhancing the operator and passenger experience through intuitive mode transitions and feedback.
Implementation Method 1
As the craft gains speed, the craft's hydrofoils cause the hull to rise above the surface of the water
Implementation Method 2
As the craft gains even more speed, lift is generated by aerodynamic surfaces of the craft's wings to cause the craft to become airborne
Data Source
AI summary
A craft is provided with a lever that can control the power/speed of the craft and semi-automatically transition the craft in various modes of operation. This makes control of the craft somewhat similar to control of a boat, thereby bringing a maritime flight control experience to a wing-in-ground effect vehicles, hydrofoiling vessels, seagliders, and seaplanes. Further, various audio, visual, and/or haptic devices in the cockpit can provide alerts/feedback to the operator on the use of the lever and mode transitions.
