Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
HVAC systems face challenges with traditional P-traps due to the need for standing water, which can freeze and lead to sludge buildup, and require extensive installation, making them inefficient and prone to air leaks.
Innovation Solution
A compact automatic condensate release device with a spherical valve and helical spring mechanism that operates dry, allowing condensate to flow while preventing gas passage, eliminating the need for standing water and reducing installation complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional P-trap is used for condensate drainage, then condensate can be effectively drained, but standing water is required which can freeze and lead to sludge buildup
Solution Approach 1:
The invention extracts the water seal function from the traditional P-trap structure by using a floating ball mechanism that operates without standing water. The ball float rises with condensate level and opens the valve when reaching a predetermined height, eliminating the need for water accumulation while maintaining drainage functionality.
Solution Approach 2:
The floating ball mechanism automatically responds to condensate level changes, opening the valve when the ball rises to a predetermined height and closing it when the level drops. This self-actuating system eliminates the need for external control mechanisms or standing water to maintain the seal.
2Reliability
If a traditional P-trap is used for condensate drainage, then condensate can be effectively drained, but extensive installation is required making it complex
Solution Approach 1:
The invention segments the trap body into modular components including a float chamber, valve seat, and connection ports that can be easily assembled. The floating ball mechanism is integrated into the trap body as a compact unit, reducing overall installation complexity while maintaining effective condensate drainage functionality.
3Reliability
If a traditional P-trap is used for condensate drainage, then condensate can be effectively drained, but air leaks occur due to lack of water seal
Solution Approach 1:
The floating ball acts as an intermediary mechanism that responds to condensate level changes and controls valve opening/closing. When the ball rises to the predetermined height, it lifts the valve to allow condensate drainage, and when the level drops, the ball closes the valve to prevent air leakage, maintaining system integrity without requiring standing water.
