Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Heating-cooling systems face issues with condensation formation, which can lead to malfunction or damage due to inadequate condensate removal, particularly exacerbated by increased furnace vent lengths and large internal volumes in condensate traps, reducing installation flexibility and affecting pressure management.
Innovation Solution
A condensation trap design featuring an inlet chamber, vent chamber, and outlet chamber with a larger internal vent volume than the inlet chamber, facilitating compact size and efficient condensate drainage, along with a manufacturing method using a mold and injection molding process to produce the trap.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If the furnace vent length is increased, then the condensate trap must operate under larger atmospheric pressure changes, but this reduces installation flexibility and increases minimum trap size
Solution Approach 1:
The trap is divided into distinct chambers (inlet chamber, vent chamber, outlet chamber) with specific functions, allowing each segment to be optimized for its purpose while maintaining overall compactness
Solution Approach 2:
The patent changes the volume parameter relationship, making the vent chamber volume greater than the inlet chamber volume, which optimizes pressure equalization while maintaining compact dimensions for flexible installation
2Reliability
If the condensate trap has large internal volume to handle pressure changes, then it can manage atmospheric pressure variations, but this increases the minimum size and reduces installation flexibility
Solution Approach 1:
The patent optimizes the volume parameters by making the vent chamber volume greater than the inlet chamber volume, achieving effective pressure management while minimizing overall trap size for flexible installation
Solution Approach 2:
The patent arranges chambers in a compact three-dimensional configuration with vertical and horizontal passageways, achieving sufficient internal volume for pressure management within a small external footprint
3Adaptability or versatility
If the condensate trap is designed with compact size for flexible installation, then installation flexibility is improved, but this may reduce the volume available for pressure equalization
Solution Approach 1:
The patent uses efficient three-dimensional chamber arrangement and vertical passageways to maximize internal volume within compact external dimensions, maintaining pressure equalization capability while achieving flexible installation
Solution Approach 2:
The patent optimizes the volume ratio between vent chamber and inlet chamber, ensuring sufficient pressure equalization volume is allocated to the vent chamber while keeping overall dimensions compact
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design allows for effective condensate management without losing prime under varying pressures, enabling a compact and flexible installation that maintains system performance and prevents damage from condensation.
Implementation Method 1
One technical feature of the trap is an internal vent volume portion that is larger than an inlet chamber internal volume. This feature facilitates the trap's ability to accommodate certain inlet pressures without causing the trap to lose its prime
Implementation Method 2
The inlet chamber, vent chamber, and outlet chamber facilitate compact size and efficient condensate drainage

AI summary
A condensation trap comprising an inlet chamber, a vent chamber and an outlet chamber. The inlet chamber is configured to receive condensate fluid through an external opening therein. The vent chamber is in fluid communication with the inlet chamber via a first passageway that includes an internal opening of the inlet chamber. The internal opening is located substantially at an opposite end of the vent chamber as the external opening. The outlet chamber is in fluid communication with the vent chamber via a second passageway that includes an internal opening in a sidewall of the vent chamber and an interior opening in an end of the outlet chamber. The outlet chamber is configured to transmit the condensate fluid through an exterior opening located at an opposite end of the outlet chamber. A vent volume portion is greater than a total volume of an internal space of the inlet chamber.
