Modular Watercraft Wireless Control Signal Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing watercraft with motor drives face challenges in reliable operation, especially with smaller designs that can submerge, due to signal damping in water, leading to unreliable remote control functionality and potential cable damage during use.
Innovation Solution
A modular watercraft design with a stern and bow module connected by a first mechanism, utilizing a control device and remote control with a transmitting device on the bow module and a receiving device on the stern module, allowing for reliable signal transmission through short paths, potentially wireless, and featuring a jet drive module with a rigid housing for stability and a power supply module for flexibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a cable connection is used between the operating device and the watercraft, then the control connection is reliable, but the cable is cumbersome and can be torn out easily during a fall
Solution Approach 1:
The patent replaces the mechanical cable connection with a wireless communication system consisting of a transmitting device in the bow module and a receiving device in the stern module. This eliminates the physical cable that could be torn during falls, while maintaining reliable control signal transmission through wireless communication protocols.
2Ease of operation
If wireless remote control is used, then the operational convenience is improved, but the signal transmission becomes unreliable in smaller watercraft that can submerge
Solution Approach 1:
The watercraft is divided into modular segments (bow module and stern module) with the transmitting device placed in the bow module and the receiving device in the stern module. This segmentation allows the wireless communication system to be integrated into the modular structure, ensuring reliable signal transmission even when the watercraft submerges or changes configuration.
3Adaptability or versatility
If the watercraft is designed as a modular system with connected modules, then the flexibility and ease of maintenance are improved, but the structural complexity increases
Solution Approach 1:
The modular design employs universal connection mechanisms and standardized interfaces that allow different modules (bow module, stern module, jet drive module, power supply module) to be interconnected in various configurations. The control system is designed to recognize and adapt to different module arrangements, providing multi-functionality and configuration flexibility without proportionally increasing system complexity.

AI summary
A watercraft including: a motor drive; a stern module; a bow module releasably connected to the stern module by a first connector; a controller; and a remote control configured to be operated by an operator. The remote control being configured to transfer movement control signals to the controller for operating the motor drive. Where the stern module having a first receiver, and the bow module having a transmitter. The transmitter is connected to the remote control and is configured to transmit the movement control signals received from the remote control. The first receiver is configured to receive the movement control signals from the first transmitter and forward the movement control signals to the controller.
