Axial Dispenser Orifice and Modular Applicator Pad Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dispenser and applicator heads face challenges in accurately depositing fluids due to a laterally oriented dispenser orifice and lack of modularity, making it difficult for users to locate the orifice and change applicator pads.
Innovation Solution
A dispenser and applicator head design featuring a fluid dispenser member with a connector base and mounting collar, allowing for axial mounting of an applicator pad and positioning the dispenser orifice at the tip, enabling precise fluid deposition and easy swapping of applicator pads.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the dispenser orifice is formed through the applicator pad or opens laterally, then the applicator pad can be made large for fluid spreading, but the user cannot accurately locate the dispenser orifice for precise fluid deposition
Solution Approach 1:
The head is divided into distinct functional zones: the applicator pad area for fluid spreading and the tip area with the axially oriented dispenser orifice for precise fluid deposition. This segmentation allows each zone to optimize its function independently, with the orifice positioned at the tip for easy location and accurate targeting.
2Adaptability or versatility
If the applicator pad is mounted by overmolding in the head body, then the structure is integrated and stable, but the system lacks modularity and applicator pad replacement is difficult
Solution Approach 1:
The mounting structure transitions from a static integrated design to a dynamic modular system where the applicator pad can be easily attached and detached. The recess and retainer mechanism enable quick replacement while maintaining structural stability during use.
3Area of stationary object
If the dispenser orifice is arranged laterally in a wide zone, then the applicator pad has sufficient area for spreading, but the user experiences difficulty in accurately targeting the desired location
Solution Approach 1:
The dispenser orifice is repositioned from a lateral arrangement in the wide zone to an axial arrangement at the tip of the head. This dimensional change in orifice positioning allows the applicator pad to maintain its large spreading area while the orifice provides precise targeting capability at the forwardmost point.
