Urinal Screen Date Tabs for Maintenance Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Urinal screens and mats deteriorate quickly in harsh environments, losing their air freshening and sanitizing functions, making it difficult for users to determine when to replace them effectively, as traditional expiration labels are unsuitable and prone to damage or disintegration.
Innovation Solution
Incorporating a date feature with removable and durable date tabs or pins on urinal screens and mats, allowing end-users to easily record and verify installation or replacement dates, independent of manufacturer-provided expiration dates, and using fragrance-loaded plastic materials resistant to environmental damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If traditional printed expiration labels are applied to urinal screens and mats, then product expiration information can be provided, but the labels are washed away, damaged, or eroded by the harsh environment and foot traffic
Solution Approach 1:
The patent uses disposable adhesive labels that are intentionally designed to be temporary and replaceable. The labels are applied to the urinal screens and mats and can be easily removed and replaced when expired, rather than being permanent fixtures. This approach accepts the short lifespan of the label itself, focusing on its function to convey expiration information during its brief presence.
Solution Approach 2:
The patent employs color-changing indicators or visually distinct labels that can be easily seen on the urinal screens and mats. The labels use high-contrast colors or color changes to indicate expiration status, making them noticeable even in harsh lighting conditions and ensuring users don't miss the expiration information.
2Loss of information
If manufacturer-provided expiration dates are added to products, then expected product lifespan can be indicated, but the dates do not account for varying installation timelines and usage patterns of different customers
Solution Approach 1:
The patent includes pre-printed expiration dates on the urinal screens and mats at the time of manufacture. This preliminary action provides a baseline expiration timeline that accounts for typical product lifespan under normal conditions. The dates are predetermined based on standard usage patterns but serve as a starting point that can be adjusted by users.
Solution Approach 2:
The patent allows the expiration date information to be dynamic rather than fixed. Users can modify the pre-printed expiration dates based on their specific installation timelines, usage patterns, and observation of product condition. The system transitions from a static manufacturer-provided date to a flexible user-adjustable date that adapts to actual usage conditions.
3Reliability
If urinal screens and mats are changed periodically to maintain function, then air freshening and sanitizing functions are preserved, but replacement frequency increases maintenance complexity and draws attention to product deterioration
Solution Approach 1:
The patent incorporates visual feedback mechanisms such as color-changing indicators, expiration date labels, or status markers that clearly indicate when the urinal screens and mats need to be replaced. This feedback system provides intuitive information to users about product condition and replacement timing, eliminating the need for complex maintenance tracking systems.
Solution Approach 2:
The patent designs the urinal screens and mats with self-indicating features that automatically communicate their replacement status to users. The products essentially tell users when they need to be replaced through visible cues like expiration dates or condition indicators, making the maintenance process simple and user-driven rather than requiring complex scheduling or monitoring systems.

Data Source
AI summary
A urinal assembly having a screen body with a date feature corresponding to days, weeks, months, years, quarters or other time intervals. The date feature includes date tabs that may be removably attached to the screen body that may be removed or altered to indicate the desired date, such as a date of installation or expiry date of the urinal screen. The date feature and date tabs may be molded together with the remainder of the urinal screen body, forming a one piece construction made of a plastic material that may withstand the harsh environmental conditions within a urinal or toilet.
