Disposable Sewer Clean Out Notification Disc
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for accessing and maintaining main sewer lines, especially after trenchless repairs or installations like backflow valves and grease traps, lack a durable and reliable notification mechanism, risking damage from improper plumbing operations if notifications become unreadable or are removed.
Innovation Solution
A durable clean out notification disc made of materials like ABS or high-density polyethylene, placed underneath the clean out cover, provides long-lasting notification of conditions such as trenchless repairs, backflow valves, or grease traps, preventing damage by indicating when an augur or snake should not be used.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a sticker or tag is placed on the clean out to notify of trenchless repair, then notification is provided, but the notification becomes unreadable or is removed over time, leading to potential damage
Solution Approach 1:
The patent replaces the permanent but fragile sticker/tag with a disposable notification disc that is intentionally designed to be removed after serving its purpose. The disc provides reliable notification during the critical period and can be easily replaced, solving the durability-readability contradiction through planned obsolescence.
Solution Approach 2:
The notification disc uses color-coding and visual parameters to convey information about the sewer line condition. By changing visual parameters (colors, symbols) rather than relying on text that can become unreadable, the system maintains notification effectiveness over time.
2Duration of action of stationary object
If a durable notification mechanism is used, then notification longevity is improved, but the mechanism may become difficult to remove or update
Solution Approach 1:
The notification disc is designed with dynamic characteristics - it is inserted friction-fit for long-term durability but includes a removal mechanism (such as a tab or breakable feature) that allows easy extraction when needed. This resolves the contradiction between longevity and ease of removal.
Solution Approach 2:
The disc is segmented into a body that provides durable notification and a removal feature (such as a tab or breakable section) that allows easy extraction. This segmentation enables the disc to be both durable during service and easy to remove when updated.
3Loss of information
If multiple notifications are placed on the clean out, then comprehensive information is provided, but the clean out becomes cluttered and difficult to read
Solution Approach 1:
The notification disc is designed as a universal platform that can convey multiple types of information through standardized color-coding and symbols. A single disc can indicate multiple conditions (trenchless repair, backflow valve, grease trap) without requiring multiple separate notifications, thus providing comprehensive information while maintaining simplicity.
Solution Approach 2:
Instead of stacking multiple linear notifications, the system uses color-dimensions and symbolic representations to encode multiple pieces of information in a single visual element. This dimensional encoding allows comprehensive information delivery without physical clutter.

AI summary
A clean out notification disc is placed in a clean out underneath a clean out cover to provide a durable notification mechanism of certain conditions of a main sewer line, such as, for example, the existence of a sewer liner, a backflow valve or a grease trap.
