Solution Overview
Problem
Existing devices for dispensing fluid filling compounds downstream of a static mixer face challenges in securely fixing a tubular element and minimizing pressure loss, which affects the precise delivery and application of the compound.
Innovation Solution
A device featuring a static mixer with a housing containing a mixing element and an outlet element, where the tubular element is securely fixed with a widening at its inlet opening, and a conical outlet element design that reduces pressure loss by gradually reducing the cross-sectional area, ensuring the filling compound flows efficiently and is applied accurately.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a tubular element is used to deliver filling compound downstream of a static mixer, then precise delivery to the destination is achieved, but the tubular element is not securely fixed and causes pressure loss
Solution Approach 1:
The device is divided into distinct functional segments: the static mixer housing with first cavity, the outlet element with second cavity, and the tubular element. This segmentation allows each component to be optimized independently while ensuring proper fixation through the widening at the tubular element's inlet opening that engages with the outlet element.
Solution Approach 2:
The tubular element is nested within the outlet element's second cavity, creating a hierarchical structure where the smaller tubular element is contained within the larger outlet element. The widening at the inlet opening of the tubular element provides an engagement feature that secures it within the outlet element, preventing displacement while maintaining precise delivery capability.
2Loss of energy
If a tubular element with small diameter is used to reduce pressure loss, then pressure loss is minimized, but the tubular element is difficult to secure firmly
Solution Approach 1:
The tubular element features a localized widening at its inlet opening, creating a specific engagement zone. This local quality change allows the otherwise small-diameter tubular element to be securely fixed within the outlet element through the enlarged inlet opening that engages with the outlet element structure.
3Loss of energy
If the outlet element has a conical design to reduce pressure loss, then pressure loss is reduced and material consumption is optimized, but the structural complexity increases
Solution Approach 1:
The outlet element employs a conical design with a gradually varying cross-sectional area, transitioning from a larger base to a smaller apex. This curved geometric form reduces pressure loss by enabling smooth fluid flow transition, and is integrated into the injection-molded housing structure, minimizing additional manufacturing complexity.
4Loss of energy
If the tubular element has a maximum length of 100 mm to reduce pressure loss, then pressure loss is minimized, but the delivery range is limited
Solution Approach 1:
The tubular element's dimensions are optimized with specific parameter ranges: outer diameter of at most 3 mm (preferably 2.5 mm or 1.5 mm), inner diameter corresponding to the outer diameter, and length of at most 100 mm (preferably 50 mm or 30 mm). These parameter changes balance pressure loss reduction with adequate delivery capability.
