Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing amphibious bicycles face challenges in transitioning from land to water without additional components or modifications, often causing instability and inconvenience due to bulky airbags and the need for component detachment or addition.

An amphibious bicycle design featuring foldable floating means on front and rear wheel frames, powered by underwater motors and rotary blades, allowing seamless transition and propulsion on water without additional components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If airbags are mounted on both sides of the bicycle to enable floating on water, then buoyancy is improved, but the bicycle becomes bulky in width and difficult to control on land
Solution Approach 1:
The airbags are designed to be movable rather than fixed, capable of being folded down during land travel and unfolded during water travel. This dynamic configuration allows the bicycle to adapt its structure according to the operating environment, resolving the contradiction between buoyancy and control stability.
Solution Approach 2:
The floating mechanism is divided into separable components (airbags that can be independently folded and unfolded) rather than a permanent fixed structure. This segmentation allows the buoyancy elements to be deployed only when needed, maintaining control stability on land while providing buoyancy on water.
2Reliability
If airbags are mounted on the bicycle for water operation, then floating capability is improved, but the airbags may contact the ground and be damaged during land travel
Solution Approach 1:
The airbags are designed with dynamic positioning capability, being folded down during land travel to avoid ground contact and unfolded during water travel to provide floating capability. This dynamic adjustment prevents damage while maintaining functionality.
3Adaptability or versatility
If conventional amphibious bicycles are used, then water travel is enabled, but additional devices must be detached or added during mode conversion, causing inconvenience
Solution Approach 1:
The bicycle is designed with integrated multi-functional components that serve dual purposes: the airbags provide both structural support and buoyancy, the propulsion means works on both land and water, and the steering means controls direction in both environments. This universality eliminates the need for detaching or adding components during mode conversion.
Solution Approach 2:
The floating means, propulsion means, and steering means are merged into an integrated system where all components work together on both land and water without requiring separate configurations or additional devices, simplifying the mode conversion process.

Enables stable and efficient land-to-water transition and water propulsion with controlled speed and direction, ensuring rider comfort and convenience.
Implementation Method 1
a first floating means that is mounted onto front wheel frames rotating along with a handlebar and unfolds due to buoyancy when the amphibious bicycle enters water, thereby keeping the front wheel frame afloat
Implementation Method 2
a propulsion means having a plurality of rotary blades and motors on a rear wheel rotating by pedals, so that a propelling force is produced even on water

AI summary
Provided is an amphibious bicycle and, more specifically, to an amphibious bicycle characterized by including: a first floating means that is mounted to a front wheel frame rotating along with a handle and unfolds due to buoyancy upon entering water, thereby keeping the front wheel frame afloat; a second floating means that is mounted to a rear wheel frame and unfolds due to buoyancy upon entering water, thereby keeping the rear wheel frame afloat; a propulsion means that propels the amphibious bicycle forward when the amphibious bicycle enters water, and a steering means by which the amphibious bicycle can change direction while moving forward in water, wherein the amphibious bicycle can transition directly from traveling on land to entering and moving across water without any additional work or replacement or addition of components.
