Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drain systems for tankless water heaters are inefficient in collecting and directing condensate and leaks, leading to potential water damage and requiring improved solutions for effective liquid management.
Innovation Solution
A drain assembly comprising a stand with a drain pan and an outlet conduit that directs liquid away from the heater, incorporating a leak detection system to alert users of leaks, and allowing for easy installation and maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If condensate is allowed to fall toward the ground without collection, then the system is simple, but water damage occurs and liquid management is ineffective
Solution Approach 1:
The drain system is segmented into distinct functional components: a drain pan for collection, a stand with support structure, and an outlet conduit for discharge. This segmentation allows each component to perform its specific function efficiently while maintaining overall system reliability in preventing water damage.
Solution Approach 2:
The drain pan acts as an intermediary component between the heater assembly and the ground, intercepting condensate before it can cause water damage. This mediator approach effectively manages liquid flow without requiring direct contact between the heater and collection system.
2Productivity
If a drain pan is positioned below the heater to collect liquid, then liquid collection is effective, but the device structure becomes more complex
Solution Approach 1:
The drain pan and stand are merged into an integrated assembly where the pan is positioned within the stand structure. This merging combines the collection function with the support structure, improving liquid collection efficiency while minimizing the increase in overall structural complexity.
Solution Approach 2:
The drain pan is positioned in a vertical dimension below the heater assembly, utilizing the vertical space to collect liquid without expanding the horizontal footprint. This dimensional approach enables effective liquid collection while maintaining a compact overall structure.
3Ease of operation
If an outlet conduit is added to direct liquid away from the heater, then liquid management is improved, but the device complexity increases
Solution Approach 1:
The outlet conduit is extracted as a separate, removable component from the drain assembly, allowing it to be easily installed and maintained independently. This extraction approach improves liquid direction effectiveness while enabling simple maintenance without requiring disassembly of the entire drain system.
Solution Approach 2:
The outlet conduit is designed with flexible positioning capabilities, allowing it to be directed toward different drain locations as needed. This dynamic adjustability improves liquid management flexibility while maintaining a relatively simple component structure.
