Integrated Block Channel Body for Precise Fluid Dosing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dosing devices for fluid output are complex and costly to manufacture, requiring nozzle needles that complicate assembly and cleaning, and often result in irregular fluid distribution due to air bubble formation.
Innovation Solution
The dosing channel system is integrated directly into a block-shaped channel body, eliminating the need for nozzle needles and allowing for precise manufacturing of channel cross-sections, which reduces complexity and space requirements while ensuring consistent fluid flow to minimize air bubble formation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If nozzle needles are used to define output sections, then precise dosing is achieved, but device complexity and manufacturing cost increase
Solution Approach 1:
The patent merges the dosing channel system and output channels into a single integrated block-shaped channel body. The output channels with narrowed output sections are formed directly in the channel body, eliminating the need for separate nozzle needles and fastening means. This integration maintains precise dosing capability while significantly reducing device complexity and assembly steps.
Solution Approach 2:
The block-shaped channel body serves multiple functions simultaneously: it acts as the structural housing, contains the dosing channel system, forms the output channels with precise cross-sections, and provides the narrowed output sections for dosing. This multi-functionality eliminates the need for separate specialized components like nozzle needles.
2Manufacturing precision
If nozzle needles are fastened to channel body, then output section precision is achieved, but manufacturing cost and space requirements increase
Solution Approach 1:
The output channels with precisely defined cross-sections are formed as an integral part of the block-shaped channel body through molding or machining. This eliminates the need for separate nozzle needles and fastening means, reducing manufacturing steps and costs while maintaining output section precision.
3Reliability
If separate nozzle needles are used, then dosing capability is achieved, but cleaning effort increases
Solution Approach 1:
The entire dosing channel system including output channels is integrated into the block-shaped channel body as a single unit. This allows the entire system to be cleaned with a single rinsing operation, eliminating the need to disassemble and clean separate nozzle needles, thereby reducing cleaning effort while maintaining dosing capability.
4Volume of moving object
If channel body is designed compactly without fastening means, then space requirements are reduced, but manufacturing precision may be compromised
Solution Approach 1:
The output channels with precise cross-sections are formed directly in the block-shaped channel body through molding or machining processes. This integration allows for precise control of channel cross-sections while maintaining a compact design without fastening means, as the precision is achieved through the manufacturing process itself rather than through assembled components.

AI summary
A dosing device is proposed which is designed for dosed output of a fluid. The dosing device has a block-shaped channel body, through which a dosing channel system passes. The dosing channel system has a fluid infeed opening and a plurality of fluid output openings. The fluid output openings are formed by the channel apertures of narrowed output sections of a plurality of output channels of the dosing channel system. The entire dosing channel system, including the output channels, is formed in the block-shaped channel body. The dosing channel system is preferably structured such that the flow velocity of the fluid channelled through during operation is at least substantially the same throughout with the exception of in the output sections of the output channels.
