An outlet assembly for arrangement at a wall opening in an outer wall of a dispenser for web-shaped absorbent material
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dispensers for web-shaped absorbent materials face challenges in efficiently switching between one-by-one and continuous dispensing modes without a time-efficient and secure attachment of different dispensing outlets.
Innovation Solution
An outlet assembly with interlocking parts, featuring protruding portions and fastening bores, allows for a two-step detachment process and secure attachment to a dispenser, ensuring reliable and efficient switching between dispensing modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional outlet assembly with a single large aperture is used, then the web-shaped absorbent material can pass through, but the material tends to deform and stick to the outlet assembly, causing irregular dispensing
Solution Approach 1:
The outlet aperture is divided into multiple smaller aperture elements arranged in an array pattern. This segmentation prevents the web-shaped material from deforming and sticking by providing multiple smaller exit paths instead of a single large opening, thereby ensuring consistent and reliable dispensing of the material.
2Device complexity
If the outlet assembly has a simple single aperture design, then the device complexity is low, but the material may become trapped between the dispenser and the outlet assembly
Solution Approach 1:
The outlet assembly incorporates multiple aperture elements in an array configuration, which prevents material trapping between the dispenser and outlet while maintaining a relatively simple overall structure. The segmented aperture design allows material to pass through multiple small openings rather than one large opening, reducing the risk of trapping.
Solution Approach 2:
The outlet assembly includes a protrusion extending toward the dispenser, creating a three-dimensional configuration that prevents material trapping. This dimensional addition allows the material to be guided properly through the aperture array without becoming caught between surfaces.
3Ease of manufacture
If a single large aperture is used in the outlet assembly, then manufacturing is simple, but the material may be dispensed too quickly or in an uncontrolled manner
Solution Approach 1:
The single large aperture is segmented into multiple smaller aperture elements arranged in an array. This segmentation provides better control over the dispensing rate of the web-shaped material while still allowing for relatively simple manufacturing processes. The multiple small openings distribute the material flow more evenly and controllably.
