Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional toilets for male users often lead to unsanitary and embarrassing situations due to urine spillage around the bowl, seat, and floor during standing urination, and existing urinal solutions are not economically viable or aesthetically acceptable for residential use.
Innovation Solution
A convertible urinal integrated lid system for conventional toilets, featuring a lower and upper lid coupled by hinges with magnetic securing mechanisms, forming a fluidically sealed cavity with outlet apertures for cleansing fluids, allowing for secure, hygienic, and adjustable urination in both standing and seated positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a conventional toilet is used for standing urination, then the toilet structure is simple and cost-effective, but urine spillage occurs around the bowl, seat, and floor creating unsanitary conditions
Solution Approach 1:
The lid is divided into two functional parts: a toilet lid portion and a urinal shield portion. This segmentation allows the shield to redirect urine away from harmful areas while maintaining the simplicity of the conventional toilet structure.
Solution Approach 2:
The urinal shield acts as an intermediary element between the user and the toilet bowl. It intercepts and redirects urine flow, preventing direct contact with the bowl, seat, and floor, thereby eliminating spillage without requiring a complete toilet redesign.
2Object-affected harmful factors
If a urinal shield is added to redirect urine, then urine spillage is prevented, but the device complexity increases
Solution Approach 1:
The urinal shield is merged with the toilet lid to form a single integrated assembly. This combining approach allows the shield to perform its urine-redirection function while utilizing the existing lid mounting structure, thereby minimizing the increase in overall device complexity.
Solution Approach 2:
The lid assembly serves multiple functions: it closes the toilet bowl for normal toilet use and acts as a urinal shield when positioned in the open configuration. This multi-functionality reduces the need for separate components, keeping the device complexity low while effectively preventing urine spillage.
3Reliability
If the urinal shield is secured to the lid with strong force, then the shield remains stable during use, but the lid cannot be easily opened or closed
Solution Approach 1:
The coupling mechanisms are designed with dynamic characteristics that allow them to engage firmly during normal use (providing stability) but can be easily disengaged when sufficient force is applied (enabling operation). This dynamic behavior resolves the contradiction between stability and ease of operation.
Solution Approach 2:
The coupling mechanisms automatically engage when the shield is installed and provide self-locking stability during use. However, they are designed to release when a specific operational force is applied, allowing the user to open or close the lid without requiring tools or complex mechanisms.
4Shape
If the urinal shield is made rigid to maintain shape, then it provides effective urine redirection, but it cannot be easily installed or removed
Solution Approach 1:
The shield incorporates flexible elements that allow it to bend slightly during installation and removal, making the process easier. Once installed, the flexible elements maintain sufficient rigidity to provide effective urine redirection. This dynamic flexibility resolves the contradiction between shape maintenance and installation ease.

Function Achieved in This Case
The system effectively prevents urine spillage, maintains hygiene, and integrates urinal functionality into any western bathroom, enhancing user experience and acceptance by providing a family-friendly, economically viable solution.
Implementation Method 1
a first coupling mechanism secures the lower lid to the upper lid, wherein the first coupling mechanism applies a first securing force between the lower lid and the upper lid; and a second coupling mechanism secures the upper lid to a toilet water tank

AI summary
A urinal integrated lid system is provided which may utilize a toilet seat, a lower lid and an upper lid such that one or more hinges couple the toilet seat, the lower lid and the upper lid together. The system may further utilize a first coupling mechanism securing the lower lid to the upper lid and a second coupling mechanism secures the upper lid to a toilet water tank such that, after the second coupling mechanism secures the upper lid to the toilet water tank, a separation force may separate the lower lid from the upper lid. After separation of the lower lid from the upper lid, the lower lid may rotate via the one or more hinges through an angle range of 0 degrees to 75 degrees with respect to the upper lid.
