Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing condensate traps for HVAC/R systems are prone to installation errors, damage, and failure due to their complex designs, difficulty in cleaning, and susceptibility to clogging, which can lead to condensate backup and damage to equipment and surrounding structures.
Innovation Solution
A compact, efficient condensate trap design featuring a main body with a condensate inlet and outlet, an internal reservoir, and an adjustable inlet pathway that forms a gas seal to prevent air inhalation, along with a removable cover for easy access and cleaning, and optional air vents and a liquid level sensor for monitoring.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a P-trap or traditional pipe-based trap is used, then a gas seal can be formed to prevent air inhalation, but the trap becomes difficult to clean and install
Solution Approach 1:
The trap is divided into a modular design with a removable cap that separates the cleaning access from the gas seal formation area. This allows the liquid reservoir to be accessed for cleaning without compromising the integrity of the gas seal mechanism, resolving the contradiction between maintaining effective sealing and enabling easy maintenance.
Solution Approach 2:
The inlet pathway is extracted as a separate, adjustable component that can be modified or removed independently. This extraction allows for easier cleaning and maintenance of the liquid flow path without affecting the overall gas seal structure, addressing the cleaning difficulty while preserving seal effectiveness.
2Reliability
If a P-trap or traditional pipe-based trap is used, then a gas seal can be formed to prevent air inhalation, but installation becomes error-prone and complex
Solution Approach 1:
The trap assembly is segmented into pre-fabricated modules including the main body, inlet pathway, and removable cap. This segmentation allows for simplified installation where components are assembled in a standardized sequence, reducing installation errors compared to traditional custom-fitted pipe traps while maintaining gas seal reliability.
Solution Approach 2:
The inlet pathway is pre-configured with adjustable features and connection points during manufacturing. This preliminary action eliminates the need for complex on-site cutting, fitting, and gluing operations, thereby reducing installation complexity and error rates while preserving the gas seal formation capability.
3Ease of manufacture
If the inlet pathway is fixed, then installation is simpler, but the trap cannot adapt to different negative pressure conditions
Solution Approach 1:
The inlet pathway incorporates an adjustable feature that allows the liquid level and pathway configuration to be modified based on operating conditions. This dynamic adjustment capability enables the trap to adapt to varying negative pressure conditions while maintaining a standardized installation process, resolving the contradiction between installation simplicity and operational adaptability.
4Productivity
If traditional traps are used, then condensate can drain, but air can be pulled in through the drainage outlet due to negative pressure
Solution Approach 1:
A liquid intermediary is maintained in the trap reservoir to create a physical barrier between the drainage outlet and the air intake path. This liquid seal acts as an intermediary that allows condensate to drain through while blocking air from being pulled in during negative pressure conditions, simultaneously achieving drainage productivity and preventing air inhalation.
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 ensures reliable condensate drainage, minimizes installation errors, and facilitates maintenance, reducing the risk of damage and costly repairs by creating a gas seal that prevents air inhalation and allowing for easy cleaning and monitoring of condensate levels.
Implementation Method 1
A trap may be attached to the drainage outlet of the HVAC/R unit to allow condensate to drain, while preventing air from being pulled in through the drainage outlet due to negative pressure. Condensate traps make use of liquid, such as purged condensate, to form a gas barrier to prevent the drainage outlet from inhaling air when the HVAC/R system is running.

AI summary
A condensate trap for providing improved gas seal to a heating, ventilation, air conditioning, and refrigeration (HVAC/R) system. The trap can include an interior reservoir containing a volume of fluid to create a gas seal between an inlet pathway and an output. The interior reservoir can be accessed through an access port, by removing a removable cover, for maintenance and inspection. The trap can include vents or vent precursors for aiding in drainage of excess fluid, as well as early detection of problem conditions. The trap can be made from modified parts put together in a specific manner, or through purpose-built parts. The trap can include liquid level sensors and inspection windows to aid in early detection of problem conditions.
