Circumferential Hook Rod for Drain Hair Extraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Bathroom drains often clog due to accumulated hair, which current methods like chemical agents or DIY solutions fail to effectively clear, posing health risks and potential damage to drain structures, and existing tools lack efficient mechanisms for circumferential hair removal without disassembling the drain.
Innovation Solution
A drain cleaning device featuring a reusable handle connected to a disposable rod section with a circumferentially oriented hook material layer on a multi-strand cable, allowing the rod to be inserted into the drain, rotated to grab hair, and easily removed without disassembling the drain, with a flexible tip for navigating bends.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If chemical agents are used to dissolve hair clogs, then the drain can be cleared, but corrosive chemicals may damage the drain structure and cause health problems
Solution Approach 1:
The patent replaces chemical dissolution methods with a mechanical extraction system. A rotatable handle drives a cable with circumferentially oriented hook elements that physically grab and extract hair clogs from the drain, eliminating the need for corrosive chemicals while maintaining effective drain clearing capability
Solution Approach 2:
The hook material layer acts as an intermediary between the user and the hair clog. The circumferentially oriented hooks on the cable serve as the mediating element that directly engages with and extracts the hair, preventing both chemical damage to the drain and health risks from chemical exposure
2Productivity
If chemical agents are used to clear drains, then hair can be dissolved, but a significant portion of the chemical flows past the clog without effectively submerging the hair
Solution Approach 1:
The invention replaces the inefficient chemical delivery system with a direct mechanical extraction mechanism. The cable with hooks is inserted directly into the clog location and rotated to engage and extract hair, eliminating the problem of chemical bypass and ensuring 100% effective contact with the obstruction
Solution Approach 2:
The device performs preliminary mechanical engagement of the hair clog before any extraction occurs. The circumferential hooks are positioned to immediately grab the hair when the cable is rotated, preventing the need to rely on chemical penetration and ensuring effective action from the start
3Ease of operation
If existing drain tools with axially oriented hooks are used, then they can grab hair, but they lack efficient circumferential hair removal capability without disassembling the drain
Solution Approach 1:
The patent employs asymmetric hook orientation where all hook elements are circumferentially oriented rather than axially oriented. This asymmetric arrangement creates a spiral or helical engagement pattern when the cable is rotated, enabling efficient circumferential hair removal that axial orientations cannot achieve
Solution Approach 2:
The circumferential orientation of the hooks creates a curved or spiral engagement path around the drain pipe. When the cable is rotated, the hooks follow a curved trajectory that effectively captures and removes hair from all circumferential directions, unlike linear axial orientations
4Adaptability or versatility
If a non-disposable drain cleaning tool is used, then it can be reused, but it requires cleaning before reuse which exposes users to unsanitary conditions
Solution Approach 1:
The device is segmented into a reusable handle section and a disposable rod section. The handle can be reused and stored sanely, while the rod that contacts the unsanitary drain environment is discarded after a single use, eliminating the need for cleaning and user exposure to contaminants
Solution Approach 2:
The rod section is designed as a low-cost disposable component that is replaced after each use. This allows the main handle to remain reusable and sanitary, while the disposable rod absorbs the sanitation issue by being discarded rather than cleaned, protecting users from unsanitary conditions

AI summary
A drain cleaning device with a combination of elements which quickly removes upper-drain hair clogs from bathroom drains without taking the drain apart, and without handling offensive clogs. The drain cleaning device includes a handle section and a disposable drain cleaning section which snap together. The drain cleaning section has an extended rod portion with a multistrand wire core covered with a layer of thousands of miniature hair-grabbing, hook elements embedded in a textile material which covers the rod portion's entire length. In particular, the J-shaped hook elements are circumferentially oriented on the rod portion to snag hair while rotating the device. Also, a method of making the device by assembling the disposable rod section from a length of hook strip, a length of multistrand wire core, a hook-covered tip and a connector, which can then be connected to the handle section before use.
