Caseless Float Body Using High-Density Urethane
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Contemporary waterway barrier floats have a multi-component, multi-material construction that is complex to manufacture and prone to damage, with the low-density urethane float body being less robust and difficult to see once the outer casing is damaged.
Innovation Solution
A caseless float body made of high-density urethane material, which is molded with integrated mounting hardware and can be pigmented for visibility, providing strength and buoyancy without a separate outer casing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a multi-component, multi-material construction (hollow outer casing + low density urethane float body) is used, then buoyancy and light weight are achieved, but manufacturing complexity increases and structural robustness decreases
Solution Approach 1:
The patent merges the outer casing and float body into a single integrated component made of high-density urethane. This eliminates the need for separate manufacturing steps to produce the hollow casing and internal float body, and removes the assembly step required to attach them together. The single-component design maintains both buoyancy and structural robustness while significantly simplifying manufacturing.
Solution Approach 2:
The patent uses high-density urethane material that combines the buoyancy properties of low-density materials with the structural strength of hard materials. This composite material approach allows a single component to simultaneously provide both the float body and protective casing functions, resolving the contradiction between strength and manufacturing complexity.
2Strength
If a hollow outer casing is used to protect the float body, then structural strength is improved, but the float becomes more prone to damage from casing failure and visibility decreases when casing is damaged
Solution Approach 1:
The patent extracts the protective casing function from a separate component and integrates it directly into the float body material itself. The high-density urethane material inherently provides both structural protection and durability without requiring a separate hollow casing that could fail or be damaged.
Solution Approach 2:
The patent changes the material parameter from low-density urethane (which requires a protective casing) to high-density urethane (which provides inherent protection). This parameter change in material density and strength eliminates the vulnerability associated with separate casing structures while maintaining the protective function.
3Use of energy by moving object
If low density urethane material is used for the float body, then buoyancy is improved, but durability and visibility are reduced
Solution Approach 1:
The patent changes the density parameter of the urethane material from low-density to high-density formulation. This parameter change maintains the buoyancy required for float operation while simultaneously improving the material's durability, resistance to element damage, and overall service life.
