Dispenser Head With Retention Section For Single-Unit Dosing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dispensers for pharmaceutical drugs or food supplements often face issues with dosing accuracy and contamination, as users may inadvertently touch multiple units or contaminate the remaining supply.
Innovation Solution
A dispenser head with a dosing duct, support section, and retention section that allows for the controlled dispensing of a single unit at a time, preventing unwanted contact and maintaining the integrity of the remaining units.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If users take units directly from the reservoir, then they can easily access the units, but the remaining units are exposed to contamination and unwanted contact
Solution Approach 1:
The dispensing system is segmented into distinct functional zones: a reservoir for bulk storage, a dosing duct for controlled transfer, and a dispensing area with support and retention sections. This segmentation isolates the remaining units in the reservoir from direct user contact while enabling easy access to the dispensed unit at the outlet port.
Solution Approach 2:
The dosing duct acts as an intermediary mechanism that transfers units from the reservoir to the dispensing area. This intermediary structure allows users to access dispensed units without directly contacting the reservoir contents, thereby preventing contamination of remaining units while maintaining ease of access.
2Productivity
If multiple units are dispensed at once, then productivity is improved, but dosing accuracy and control are compromised
Solution Approach 1:
The dispenser is designed to dispense units in a periodic, one-at-a-time manner through the dosing duct. Each unit is transferred individually from the reservoir through the dosing duct to the support section, ensuring precise dosing control while maintaining efficient dispensing rhythm and productivity.
3Manufacturing precision
If the retention section completely blocks the unit, then dosing precision is improved, but the user cannot easily remove the unit
Solution Approach 1:
The retention section provides localized blocking at the distal end of the dosing duct to ensure precise dosing, while the support section extends beyond the retention section to provide a user-accessible area. This local differentiation allows the retention section to secure the unit for accurate dosing while the support section enables easy user removal.
Solution Approach 2:
The support section extends perpendicular to the dosing axis, creating a new dimensional space for unit retention and user access. This dimensional extension allows the unit to be securely held in one orientation (by the retention section) while providing easy access from another dimension (by the support section), resolving the contradiction between secure retention and easy removal.

AI summary
A dispenser head for dispensing a unit of a pharmaceutical drug or a food supplement or food includes a dosing duct for extending along a dosing axis and connecting an inlet port for receiving the unit from a reservoir with an outlet port for dispensing the unit. The dispenser head includes a support section for the unit, which extends from the outlet port parallel to the dosing axis. The dispenser head also includes a retention section, which extends from the support section.
