Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing floating devices in water, such as tables and chairs, tend to float away due to lateral forces from waves, making it inconvenient for users to eat or drink while in the water.
Innovation Solution
A floating device with a main body and a projecting portion that extends into the water to surround it, featuring openings for air exhaustion and potentially a reinforcement element, designed to sustain lateral forces without moving, with specific volume-to-force ratios optimizing stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a floating device is placed in water, then it can be used for leisure activities, but it floats away due to lateral forces from waves
Solution Approach 1:
The floating device is divided into two functional parts: a main body for flotation and a projecting portion for stabilization. The projecting portion extends below the water surface to surround and trap water, creating a stabilizing effect that resists lateral forces from waves while the main body provides the necessary buoyancy for leisure activities.
Solution Approach 2:
Water trapped within the projecting portion acts as an intermediary medium that provides stabilization. The projecting portion surrounds and traps water below the water surface, and this trapped water serves as a mediator that increases resistance to lateral forces, preventing the floating device from drifting away while maintaining its position for leisure use.
2Stability of the object's composition
If the projecting portion surrounds water to resist lateral forces, then stability improves, but air trapped inside reduces effectiveness
Solution Approach 1:
Air is extracted or removed from the projecting portion by providing openings that allow trapped air to escape when the device is placed in water. This ensures that the projecting portion can effectively surround and trap water without being compromised by air pockets that would reduce its stabilizing effectiveness.
Solution Approach 2:
The physical state of the projecting portion changes from air-filled to water-filled. By allowing air to escape through openings and water to enter the projecting portion, the density and mass of the projecting portion increase, thereby enhancing its ability to resist lateral forces and improve overall position stability.
3Stability of the object's composition
If the projecting portion is made rigid to resist lateral forces, then stability improves, but manufacturing complexity increases
Solution Approach 1:
The projecting portion is constructed using flexible materials such as inflatable chambers or flexible walls instead of rigid structures. These flexible components can be easily manufactured and assembled, yet when filled with water, they provide sufficient rigidity and resistance to lateral forces. This approach maintains manufacturing simplicity while achieving the required stability.
Solution Approach 2:
The projecting portion utilizes hydraulic principles by being filled with water to provide structural support and resistance to lateral forces. Instead of requiring complex rigid structures, the water-filled flexible chamber creates a hydrostatic pressure system that naturally resists external forces, simplifying manufacturing while maintaining stability.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The device remains stationary in water, allowing users to enjoy food and drinks without floating away, through effective resistance to wave-generated forces by controlling air and water within the projecting portion.
Implementation Method 1
The projecting portion extends from the main body into the water to surround a part of water for keeping the main body in position
Implementation Method 2
at least one opening is formed in the projecting portion for exhausting air surrounded by the projecting portion when the floating device is put in the water
