Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
HVAC installations and maintenance are vulnerable to refrigerant loss and contaminants such as dust, debris, and microbial agents, leading to inefficiencies and costly repairs, with no existing products addressing this issue.
Innovation Solution
A gauge device with an intake stem, split valve, and gate valve system that controls fluid flow to prevent refrigerant loss and contaminant ingress, featuring a gauge for precise measurements and contamination prevention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the HVAC system is left open during installation and maintenance, then installation and maintenance operations can be performed, but refrigerant loss and contaminant infiltration occur
Solution Approach 1:
The probe diagnostic gauge is pre-installed on the HVAC system before installation or maintenance operations begin. The valve is in a closed position by default, preventing refrigerant loss and contaminant infiltration. The system is ready for operations without requiring the gauge to be installed at the moment of need, thus preventing substance loss while allowing ease of operation.
2Ease of operation
If the HVAC system is left open during installation and maintenance, then installation and maintenance operations can be performed, but contaminant infiltration occurs
Solution Approach 1:
The probe diagnostic gauge with closed valve is pre-installed on the HVAC system before installation or maintenance operations begin. The valve is in a closed position by default, creating a barrier that prevents contaminant infiltration while allowing technicians to perform operations. This preliminary protective action eliminates harmful factors without restricting operational access.
3Reliability
If a protective device is installed on the HVAC system, then refrigerant loss and contaminant infiltration are prevented, but device complexity increases
Solution Approach 1:
The probe diagnostic gauge serves multiple functions: it acts as a protective valve to prevent refrigerant loss and contaminant infiltration, while also functioning as a diagnostic tool with pressure and temperature measurement capabilities. By combining protection and diagnostics in a single device, the patent reduces overall system complexity rather than increasing it.
Solution Approach 2:
The patent merges the protective valve function with the diagnostic gauge function into a single integrated device. The valve is built into the gauge housing, and the probe can perform both protective sealing and diagnostic measurements. This consolidation eliminates the need for separate protective devices and diagnostic tools, thereby reducing device complexity.

AI summary
The disclosure allows technicians to remove contaminants during the installation and maintenance process, preventing refrigerant loss and contamination entry into the HVAC system. Ingenious and practical this unprecedented device is uniquely designed with durable, high-quality materials to ensure long-term sustainability. This product offers removable/replaceable parts for speedy maintenance and was engineered by an HVAC technician, possessing years of experience. A gauge device comprising an intake stem comprising an intake end, a bleed end and a fluid flow there between and a gauge access in a side there between. The disclosure also includes a split valve received into the intake stem to control the fluid flow through the intake stem, a gate valve including an aperture adjacent the gauge access to control the aperture via a control arm and a gauge received in the gauge access and to take measurements of the intake stem via the aperture.
