Consumable Dispenser Latch-Tooth Mechanism for Hygienic Single-Unit Ejection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dispensing devices for consumables face challenges in maintaining sanitary dispensing habits, controlling the number of units dispensed, and ensuring consistent force of ejection, often requiring user manipulation that can lead to contamination.
Innovation Solution
A device with a housing, drawer, cap, latch, and tooth mechanism that allows for single-handed operation with a threshold force to dispense a consumable unit, using magnetic coupling and spring biases to ensure consistent and hygienic dispensing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If a ratchet mechanism is used to dispense consumable units, then the dispensing action is automated, but the force of ejection becomes inconsistent and unreliable
Solution Approach 1:
The spring mechanism provides periodic, consistent force through controlled expansion cycles. Each spring expansion delivers a standardized ejection force to the consumable unit, ensuring reliability across multiple dispensing cycles while maintaining automation.
Solution Approach 2:
The invention changes the force delivery parameter from variable (ratchet) to controlled and consistent (spring expansion). The spring's physical properties are selected to provide a specific, repeatable force that reliably ejects consumable units regardless of the number of units loaded.
2Ease of operation
If the user manually handles consumable units to control dispensing, then the number of units dispensed can be controlled, but the risk of contamination increases
Solution Approach 1:
The device performs the dispensing function automatically through the spring-tooth mechanism without requiring user handling of consumable units. The system serves itself by using the spring's expansion to eject units through the dispensing opening, eliminating user contact and preventing contamination while maintaining control over dispensing quantity.
Solution Approach 2:
The invention replaces manual mechanical handling with an automated spring-driven ejection system. The spring mechanism substitutes for user fingers and manual manipulation, providing a contamination-free method to control and dispense the required number of consumable units.
3Object-affected harmful factors
If the cap is kept closed to protect consumable units, then contamination is prevented, but the dispensing action becomes less accessible
Solution Approach 1:
The invention extracts the dispensing function from the cap structure itself, allowing the cap to remain closed for protection while the spring mechanism ejects units through a dedicated dispensing opening. This separates the protective function (closed cap) from the dispensing function (spring ejection), maintaining both contamination prevention and ease of operation.

AI summary
A device for dispensing consumables includes a housing, a drawer, a cap, a latch, and a tooth. The housing may define a volume. The drawer defines a cavity and may be disposed in the volume. The cap may be along the housing. The latch may be securable to hold the cap in a closed position enclosing the volume. In response to a force exceeding a threshold force on the latch, the cap may be movable from the closed position to an open position exposing the volume. The tooth may be mechanically coupled to the latch and, in response to the force exceeding the threshold force on the latch, the tooth may movable in the cavity in a direction directing a consumable unit out of the volume with the cap in the open position.
