Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drain cleaning machines face issues with liquid runoff and debris contamination, which can cause catastrophic damage to mechanical and electrical components, and contaminate storage locations.
Innovation Solution
A drain cleaning machine equipped with fluid management provisions, including initial, secondary, tertiary, and final fluid redirection and collection systems, to prevent liquid contact with machine components and facilitate controlled liquid collection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If drain cleaning cable is retracted from drain, then blockage is cleared, but liquid and debris are brought up with the cable causing damage and contamination
Solution Approach 1:
The patent extracts the harmful liquid and debris from the cable retraction process by introducing a separate fluid management system. The cable is retracted through a sealed entryway that prevents liquid carried on the cable from contacting internal machine components. The liquid is diverted into a collection reservoir rather than being allowed to drip onto mechanical or electrical components.
Solution Approach 2:
The patent introduces an intermediary fluid management system between the cable entry point and the machine interior. This includes a sealed cable entryway, drainage channels, and a collection reservoir that act as intermediaries to capture and contain liquid before it can reach sensitive components.
2Productivity
If cable retraction retrieves blockage, then drain is cleared, but liquid runoff contaminates storage locations
Solution Approach 1:
The patent converts the harmful liquid runoff into a contained, manageable resource. The collection reservoir captures liquid that would otherwise contaminate storage areas, and includes a drain plug that allows controlled disposal of the collected fluid in appropriate locations away from storage areas.
Solution Approach 2:
The patent extracts liquid from the general machine environment and isolates it in a dedicated collection reservoir. This separation prevents liquid from reaching storage locations and allows for controlled disposal away from sensitive areas.
3Ease of operation
If liquid contacts mechanical components, then operation is maintained, but catastrophic damage occurs
Solution Approach 1:
The patent introduces sealed barriers and drainage channels as intermediaries between liquid sources and mechanical components. The cable entryway is sealed to prevent liquid ingress, and drainage channels provide a controlled path for any liquid that does enter, directing it away from sensitive mechanical and electrical components.
Solution Approach 2:
The patent employs sealed membranes and flexible barriers at the cable entry point to prevent liquid penetration while still allowing cable movement. These seals create a protective interface that maintains machine operability while protecting against liquid damage.
