Multi-Head Dosing Arm for Cryogenic Fluid Dispensing

Solution Overview

Problem

Current cryogenic fluid dispensing systems require multiple dosers to dose multiple lines or containers simultaneously, which is expensive and increases maintenance costs, as they are not cost-effective for manufacturing and consumers.

Innovation Solution

A dosing arm with multiple dosing heads is designed, where a single doser body supplies cryogenic fluid through a central passage to multiple dosing heads, each equipped with a dosing valve, allowing for precise dispensing of cryogenic fluid to multiple receptacles simultaneously.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If multiple dosers are used to dose multiple lines or containers simultaneously, then dosing capacity and productivity are improved, but device complexity, manufacturing cost, and maintenance cost increase

Engineering Contradiction:

Improvedosing capacityVSAvoidnumber of dosers

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

Multiple dosing heads are integrated onto a single dosing arm, which is connected to one doser body. This merging of multiple dosing functions into a single coordinated unit allows simultaneous dosing of multiple containers while reducing the total number of doser bodies needed, thereby maintaining productivity while lowering device complexity and associated costs

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

A single doser body is designed to supply cryogenic fluid to multiple dosing heads through a shared central passage system. This multi-functional configuration enables one doser body to perform the work of multiple traditional dosers, improving productivity without proportionally increasing device complexity or maintenance requirements

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A doser for dispensing a cryogenic fluid includes a doser body configured to receive the cryogenic fluid. A dosing arm has a proximal end and a distal end, with a central passage extending between the proximal and distal ends and configured to receive cryogenic fluid from the doser body. Multiple dosing heads are mounted to the distal end of the dosing arm with each of the dosing heads including a dosing valve. The dosing heads are configured to receive cryogenic fluid from the central passage of the dosing arm and to dispense the cryogenic fluid when the dosing valve is opened.
