Dispensing Head Operation Inhibition Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing beer servers waste carbon dioxide gas when the gas tube is connected to the mount body without the beer container being mounted, leading to unnecessary gas discharge into the atmosphere.
Innovation Solution
A dispensing head with a fastening portion, connecting portion, gas channel, dispensing portion, and operation inhibition mechanism that prevents the gas coupling from being connected when the fastening portion is not securely fastened to the beverage container, thereby inhibiting gas wastage by ensuring the gas coupling can only be connected when the dispensing head is properly mounted.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the gas tube is connected to the mount body without the beer container being mounted, then the gas coupling can be connected to the connecting portion, but carbon dioxide gas is discharged to the atmosphere causing waste
Solution Approach 1:
The patent applies preliminary anti-action by designing an operation inhibition mechanism that prevents the gas coupling from being connected to the connecting portion unless the fastening portion is securely fastened to the beverage container mouth. This mechanism includes a blocking member that physically obstructs the connection path when the fastening portion is not properly mounted, thereby preventing gas wastage before it can occur.
Solution Approach 2:
The patent implements preliminary action by requiring the fastening portion to be securely fastened to the beverage container mouth before the gas coupling can be connected to the connecting portion. The operation inhibition mechanism ensures that the connection path is only opened after the proper mounting condition is established, preventing gas discharge to the atmosphere.
2Adaptability or versatility
If the gas coupling is connected to the connecting portion without proper mounting, then connection is possible, but gas is wasted by discharging to atmosphere
Solution Approach 1:
The operation inhibition mechanism applies preliminary anti-action by blocking the connection path between the gas coupling and connecting portion when the fastening portion is not properly mounted. This prevents the harmful effect of gas discharge to the atmosphere while maintaining the adaptability of the system when properly used.
Solution Approach 2:
The patent requires the preliminary action of securely fastening the fastening portion to the beverage container mouth before enabling the gas coupling connection. This ensures that the system only operates in the intended configuration, preventing energy waste from improper gas discharge.
3Device complexity
If the mount body is not mounted on the beer container mouth, then the structure remains simple, but gas cannot be properly contained and is discharged to atmosphere
Solution Approach 1:
The operation inhibition mechanism applies preliminary anti-action by preventing the gas coupling from being connected unless the fastening portion is properly mounted on the beverage container mouth. This simple yet effective mechanism prevents gas loss without adding complex structures to the mount body.
