Urinal Opening with 45-Degree Angle for Splashback Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing urinals often suffer from splashback issues due to their flat or inadequately angled surfaces, leading to unsightly stains on users and unhygienic restroom environments.
Innovation Solution
A urinal device featuring a bowl with a 45-degree opening that directs urine flow downwards, preventing splashback and ensuring urine enters a bottom drain without splashing back on the user.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a flat or inadequately angled surface is used in standard urinals, then the device is simple to manufacture, but splashback occurs causing urine to scatter and land on the user's clothing and shoes
Solution Approach 1:
The patent applies curvature by designing the urinal surface with a specific angle (45 degrees) and curved geometry rather than a flat surface. This curved/angled surface directs the urine stream downward along the surface, preventing splashback while maintaining manufacturing feasibility through standard forming processes.
2Object-affected harmful factors
If a flat or inadequately angled surface is used in standard urinals, then the device structure is simple, but urine droplets deflect off the urinal and contribute to an unhygienic and unsightly restroom environment
Solution Approach 1:
The patent changes the geometric parameters of the urinal surface, specifically setting the opening angle at 45 degrees relative to the horizontal plane. This parameter change optimizes the flow direction of urine, ensuring it travels downward into the drain rather than deflecting backward, thereby improving hygiene without excessive complexity.
3Object-affected harmful factors
If the opening is positioned at a 45-degree angle, then splashback is eliminated and urine flows down to the bottom drain, but the device requires specific manufacturing precision for the angled opening
Solution Approach 1:
The patent specifies a precise parameter (45-degree angle) for the opening, which balances the conflicting requirements of eliminating splashback and maintaining ease of manufacture. This specific angular parameter has been determined to be optimal for directing urine flow downward while remaining achievable through standard manufacturing processes.
Applied Scientific Principles
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 urinal device effectively reduces splashback, preventing urine from exiting the urinal and maintaining a cleaner restroom environment.
Implementation Method 1
The opening is preferably angled at 45 degrees such that a user can aim to urinate into the opening and urine will flow down the opening to a bottom drain without splashing back on a user
