Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Condensate drain lines in air conditioner systems are challenging to clean due to their inaccessible location, such as in attics, and the difficulty in reaching the source of condensate, leading to issues with buildup and debris accumulation.
Innovation Solution
A drain line cleaning device with a threaded upper portion and tapered lower portion is designed to be inserted into a plumbing connector, allowing for the introduction of cleaning fluids while preventing backflow, accompanied by a kit that includes a funnel for efficient cleaning of drain lines.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional cleaning methods are used, then cleaning effectiveness is maintained, but accessibility and ease of operation deteriorate due to the location of air handlers in attics and limited access to condensate drain lines
Solution Approach 1:
The patent introduces a cleaning device with a funnel and conduit system that serves as an intermediary tool. The funnel guides cleaning solution into the drain line while the conduit allows controlled delivery of cleaning agents, enabling effective cleaning without direct access to the air handler location. This mediator system bridges the gap between the operator and the inaccessible drain line.
Solution Approach 2:
The patent employs hydraulic principles by using fluid flow through the conduit to deliver cleaning solutions into the drain line. The controlled flow of liquid through the tapered lower portion and into the drain line enables effective cleaning without requiring physical access to the air handler, thus improving ease of operation while maintaining cleaning effectiveness.
2Productivity
If cleaning fluids are introduced into the drain line, then buildup and debris are cleared, but fluid backflow into the condensate line occurs
Solution Approach 1:
The patent inverts the typical flow direction by using a tapered lower portion that directs fluid flow forward into the drain line rather than allowing backflow. The tapered geometry creates a one-way flow path that prevents cleaning fluids from returning to the condensate line, enabling efficient cleaning while eliminating the harmful backflow effect.
Solution Approach 2:
The patent changes the geometric parameter of the cleaning device by incorporating a tapered lower portion with specific angle characteristics. This parameter change creates a flow-directional effect that prevents backflow while maintaining efficient fluid delivery into the drain line, thus resolving the contradiction between cleaning efficiency and preventing harmful fluid backflow.
3Ease of operation
If a cleaning device is inserted into the plumbing connector, then controlled fluid flow is achieved, but device complexity increases
Solution Approach 1:
The patent segments the cleaning device into distinct functional components: a funnel portion for guiding fluid, a tapered lower portion for controlled flow, and a conduit for fluid delivery. This segmentation allows each component to perform its specific function while maintaining overall simplicity. The modular design makes the device easy to operate for controlled fluid flow without requiring complex mechanisms.
Solution Approach 2:
The cleaning device is designed with multi-functionality, where the funnel and tapered lower portion serve dual purposes: guiding fluid flow and preventing backflow simultaneously. The conduit both delivers cleaning agents and controls fluid flow direction. This universality reduces the need for separate components, thereby reducing device complexity while maintaining ease of operation for controlled fluid flow.
