Distributor Head Varying Opening Dimensions for Uniform Fluid Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional distributor apparatuses for fluids, such as liquid adhesives, face irregularities in fluid distribution due to non-uniform fluid supply and pressure distributions within the distributor head, leading to incomplete coverage and uneven application on surfaces.
Innovation Solution
A distributor head with an elongate base element featuring a fluid volume, a filling opening, and distributor openings arranged on opposite sides, where the distributor openings have varying lengths and widths to compensate for pressure and distance differences, ensuring uniform fluid distribution across the surface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the distributor head uses a uniform fluid volume with standard distributor openings, then the device complexity is reduced and manufacturing is simplified, but the fluid distribution uniformity deteriorates due to pressure distributions and distance variations from the filling opening
Solution Approach 1:
The patent applies local quality by varying the dimensions of distributor openings based on their position within the fluid volume. Openings closer to the filling opening have different dimensions compared to those farther away, compensating for pressure and flow variations at different locations. This ensures uniform fluid distribution across all openings despite their different positions in the fluid flow path.
Solution Approach 2:
The patent changes the parameters of distributor openings (length, width, cross-sectional area) based on their position in the fluid volume. By adjusting these geometric parameters, the patent compensates for variations in fluid pressure and flow rate at different locations, maintaining uniform fluid distribution across all distributor openings while working within the existing fluid volume geometry.
2Productivity
If the distributor head is filled with fluid at the start, then the productivity is improved by immediate distribution, but the fluid distribution uniformity deteriorates because the fluid is initially localized near the filling opening and cannot sufficiently supply all distributor openings
Solution Approach 1:
The patent addresses the initial filling problem by making distributor opening dimensions position-dependent. Openings in different locations have optimized dimensions that account for their distance from the filling opening, ensuring that even during initial filling when fluid is localized, all openings can receive sufficient fluid for uniform distribution.
Solution Approach 2:
The patent anticipates the non-uniform distribution problem during initial filling and counteracts it through pre-designed varying opening dimensions. By preparing the distributor openings with different dimensions before operation begins, the system prevents the uniformity problem rather than correcting it during operation, allowing immediate productive use.
3Manufacturing precision
If the distributor openings are arranged in a simple pattern, then the device complexity is reduced, but the fluid distribution uniformity deteriorates due to pressure distributions within the fluid volume
Solution Approach 1:
The patent achieves uniform fluid distribution by making distributor opening dimensions position-dependent rather than uniform. Each opening's dimensions are optimized for its specific location within the fluid volume, compensating for pressure and flow variations. This approach maintains manufacturing simplicity while achieving the desired uniformity through localized dimensional variations.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution ensures uniform fluid distribution and application over the entire width and duration of the distribution process, addressing initial irregularities and pressure-related issues, resulting in a consistent and efficient application of fluids.
Implementation Method 1
pressure distributions present in the fluid can likewise lead to such irregularities
Implementation Method 2
the fluid to be distributed is stored or provided, and additionally a specific distributor head by which the actual distribution of the fluid is performed
