Solution Overview
Problem
Current systems for delivering pressurized fluids, such as carbon dioxide, face inefficiencies, safety risks, and waste due to the need for frequent tank replacements and manual valve adjustments, which disrupt beverage dispensing and can lead to overfilling and pressure hazards.
Innovation Solution
A pressurized liquid fill gun apparatus with quick connections and a valve system that allows for rapid attachment and detachment, automatic pressure sensing for filling cessation, and a method to purge residual pressure, enabling efficient and safe delivery of pressurized fluids without interrupting service or causing waste.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If manual tank replacement is performed, then the system can be refilled, but beverage dispensing service is interrupted and time is lost
Solution Approach 1:
The system enables continuous beverage dispensing during refilling operations by maintaining an active supply line. The fill gun connects directly to the dispensing system while it operates, allowing carbon dioxide to be delivered without shutting down the beverage service. This eliminates the interruption that occurs in traditional tank replacement methods.
Solution Approach 2:
A fill gun apparatus serves as an intermediary device between the carbon dioxide source and the dispensing system. This mediator allows refilling operations to occur through a dedicated connection point without affecting the main beverage dispensing flow. The fill gun acts as a bridge that separates the refilling function from the dispensing function, enabling both to operate simultaneously.
2Quantity of substance
If manual valve adjustments are made during filling, then the system can be controlled, but operator safety is compromised due to pressure hazards
Solution Approach 1:
The system performs self-regulation of the filling process through automatic pressure sensing. The fill gun monitors the pressure within the dispensing system and automatically controls the carbon dioxide flow, eliminating the need for manual valve adjustments. When the system reaches full pressure, the device automatically ceases filling, thereby protecting operators from pressure hazards while maintaining precise filling control.
Solution Approach 2:
The fill gun incorporates pressure feedback mechanisms that continuously monitor the state of the dispensing system. This feedback loop allows the device to automatically adjust the filling rate and terminate the process when the desired pressure is reached, replacing manual control with an automated safety-conscious system that responds to real-time pressure conditions.
3Productivity
If rapid connection and detachment is implemented, then delivery efficiency is improved, but connection reliability may be compromised
Solution Approach 1:
The fill gun incorporates pre-positioned alignment features and guide structures that ensure proper connection orientation before engagement. The quick-connect mechanism includes built-in alignment pins and tapered surfaces that automatically guide the connection components into correct positioning, allowing rapid attachment while maintaining secure and reliable connections without requiring manual alignment adjustments.
