Propeller Switching System for Amphibious RC Car
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional amphibious and remotely controlled cars face increased weight and power consumption due to separate transmission mechanisms for ground and water travel, or restricted performance with a single mechanism.
Innovation Solution
A propeller switching system with a controller, transmission mechanism, propeller mechanism, and wheel driving mechanism, utilizing gear sets and servo motors to switch between propeller and wheel operation based on control messages, allowing efficient adaptation for both terrestrial and aquatic environments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate transmission mechanisms are configured for ground and water travel, then adaptability is improved, but weight and power consumption increase
Solution Approach 1:
The patent implements a universal transmission mechanism that can function in both ground and water environments by using a single transmission shaft that can engage with either wheel driving mechanisms or propeller mechanisms through switching control, eliminating the need for separate transmission systems for each environment
Solution Approach 2:
The patent employs dynamic switching between different driving modes (wheel driving and propeller driving) through a switching mechanism controlled by a controller, allowing the transmission mechanism to adapt its configuration based on the operating environment (ground or water) without requiring separate fixed mechanisms
2Adaptability or versatility

3Weight of moving object
If a single transmission mechanism is used for ground and water travel, then weight is reduced, but performance and stability deteriorate
Solution Approach 1:
The patent employs dynamic switching between different driving modes (wheel driving and propeller driving) through a switching mechanism controlled by a controller, allowing the transmission mechanism to adapt its configuration based on the operating environment (ground or water) without requiring separate fixed mechanisms
Solution Approach 2:
The patent segments the driving functions into separate wheel driving mechanisms and propeller mechanisms that can be independently engaged or disengaged through the switching mechanism, allowing optimal performance for each environment while using a single unified transmission system

AI summary
A propeller switching system of an amphibious and remotely controlled car is provided, including a controller, a transmission mechanism, a propeller mechanism, and a wheel driving mechanism. When an electronic device transmits an operation message and a first control message to the controller, a propeller rotates. When the electronic device transmits the operation message and a second control message to the controller, the wheels of the amphibious and remotely controlled car rotate.
