Drain Snake Protective Cover for Twist and Kink Containment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The twisting and kinking of drain snakes or cables during obstruction removal can lead to violent releases of stored energy, potentially injuring operators, even when wearing heavy gloves.
Innovation Solution
The use of protective covers made of protective material that encircle the drain snake or cable, providing an entry opening at the containment end and a customizable exit opening at the pipe end, to prevent twisting and kinking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the drain snake or cable is used to clear obstructions in pipes, then the obstruction removal function is achieved, but the snake or cable may twist or kink when encountering resistance, storing energy that can cause injury to the operator
Solution Approach 1:
A protective cover is introduced as an intermediary component between the operator and the drain snake. The cover encircles the snake and provides a protective barrier that prevents the snake from contacting the operator's hand while allowing the snake to flex and move freely within the cover during operation
Solution Approach 2:
The protective cover is designed as a flexible cylindrical shell that can accommodate the natural movement and flexing of the drain snake during operation. The flexibility of the shell allows the snake to bend and twist as needed for clearing obstructions while the shell prevents these movements from transferring directly to the operator's hand
2Reliability
If heavy gloves are worn to protect the operator from injury, then some protection is provided, but the gloves can be caught in the twist or kink of the snake, reducing effectiveness
Solution Approach 1:
The protective cover serves as an intermediary that eliminates the need for heavy protective gloves. By providing a fixed protective barrier between the snake and the operator's hand, the cover allows operators to use lighter or no gloves while still maintaining safety, thereby eliminating the entanglement issue associated with bulky gloves
3Reliability
If the protective cover encircles the drain snake, then twisting and kinking are prevented, but the device complexity increases
Solution Approach 1:
The protective cover is designed as a simple flexible cylindrical shell with minimal structural complexity. The shell can be made from a single piece of flexible material that slips over the drain snake, requiring no complex assembly or additional components beyond the basic cylindrical structure
Solution Approach 2:
The protective cover can be implemented as a disposable component that is inexpensive to manufacture and replace. This approach reduces the complexity of designing for durability and repair, allowing the cover to be a simple, low-cost item that protects the more expensive and complex drain snake mechanism

AI summary
Protective covers made of protective material to prevent twisting and kinking of associated apparatus used for clearing obstructions in pipes or other cavities (the apparatus also commonly referred to as drain snakes) are disclosed. The cover bodies encircle the apparatus with an entry opening, closest point to the where the apparatus is coming from when the apparatus is moving toward the drain, and an exit opening, where the apparatus leaves the protective cover and moves toward or into the part being cleaned, which could be a drain, pipe or other part that material flows through. The entry and exit openings could be a section of the protective cover or they could be a separate attachable part. The protective cover body may have a handle, and may be rigid or flexible, with an option to have accordion like flexibility.
