Drain Chain System with Segmented Cap for Debris Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drain cleaning systems face challenges such as the need to remove drain caps for operation, potential hazards from protruding filters, high costs, and health risks associated with chemical de-clogging solutions, which make them impractical for frequent use or replacement.
Innovation Solution
A mechanical drain chain system that can be positioned through a hole in the drain cover to entangle and remove debris without removing the cap, featuring a flexible chain and decorative cap with interchangeable components, allowing for easy cleaning or replacement, and accommodating various drain shapes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a mechanical device is used to grab and pull debris from the drain, then de-clogging capability is improved, but the drain cap must be removed for operation
Solution Approach 1:
The device is segmented into a drain cap portion and a chain portion that can be separated. The chain can be inserted through an opening in the drain cap without removing the cap itself, allowing the de-clogging function to be performed while the cap remains in place. This segmentation resolves the contradiction by enabling mechanical debris removal without requiring cap removal.
Solution Approach 2:
The chain acts as an intermediary element that transmits the de-clogging function from the user to the drain interior. The chain can be inserted through the drain cap opening and extended into the drain plumbing, allowing mechanical intervention without direct access to the drain interior through cap removal.
2Reliability
If a surface filter is positioned over the drain to catch debris, then debris capture is improved, but safety hazards arise from protruding components
Solution Approach 1:
The chain is designed as a disposable or easily replaceable component that can be removed and discarded after use. This eliminates the need for permanent protruding filters, as the chain can be quickly replaced without creating ongoing safety hazards from fixed protruding structures.
3Reliability
If chemical de-clogging solutions are used, then temporary de-clogging results are achieved, but health risks and costs increase
Solution Approach 1:
The invention replaces chemical de-clogging systems with a mechanical chain-based system. The chain physically entangles and removes debris through mechanical action rather than chemical breakdown, eliminating health risks associated with chemical storage and handling while achieving effective de-clogging results.
4Reliability
If an expensive drain cleaning device is used, then de-clogging performance is improved, but replacement and maintenance costs increase
Solution Approach 1:
The device is divided into a durable drain cap portion and an inexpensive, replaceable chain portion. This segmentation allows the expensive cap to be retained while the low-cost chain is replaced periodically, reducing overall maintenance costs compared to replacing entire expensive de-clogging devices.
Solution Approach 2:
The chain is designed as a low-cost, disposable component that can be easily replaced when worn or contaminated. This approach reduces maintenance costs by avoiding the need to replace expensive entire devices, as only the inexpensive chain portion needs replacement.

AI summary
Drain chain systems include a cap connected to a chain. The cap rests on a drain and can include holes to facilitate the passage of water through the cap. The cap can include a decorative shape. The chain is flexible and is placed in the drain, sometimes through a hole in a drain cover. The chain can be detachably connected to the cap by a coupling element to facilitate easy replacement of the chain, or can be integrally connected to the cap. During use, hair gathers on the chain. The chain is pulled out of the drain by the decorative cap positioned over the drain. The chain can be cleaned of entangled hair and reused, or the chain can be discarded with or without the cap, by either leaving the chain connected to the cap or by detaching the chain from the cap and replacing it with a new chain.
