Solution Overview

Problem

Existing tablet dispensers fail to reliably separate and eject tablets with cuboid or prismatic geometry and fruit gums due to issues like tilting or jamming during the dispensing process.

Innovation Solution

The ejector is designed to move against a spring from a blocking position to a receiving position, exposing an opening and forming a slide that alternately releases and blocks the path, ensuring safe separation and ejection with a receptacle spanned by at least three ejector walls and an inclined base, preventing misappropriation and jamming.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If tablets are dispensed through a simple gravity-fed chute, then the device structure is simple, but tablets with cuboid or prismatic geometry and fruit gums tilt or jam during ejection

Engineering Contradiction:
Improvedispenser structureVSAvoidtablet ejection
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The ejector is divided into multiple ejector walls (first, second, third ejector walls) that form a receptacle with the container wall. This segmentation creates a structured ejection path that guides tablets through defined spaces, preventing tilting and jamming while maintaining reliable ejection for various tablet geometries including cuboid, prismatic, and fruit gum shapes.

Inventive Principle:
Principle #1Segmentation

2Reliability

If the ejector remains in a blocking position to prevent tablet leakage, then tablet separation is safe, but the opening is blocked and tablets cannot be ejected

Engineering Contradiction:
Improvetablet separationVSAvoidtablet ejection
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The ejector is designed as a movable component that dynamically transitions between a blocking position (where it prevents tablet leakage by blocking the opening) and a receiving position (where it is retracted to expose the opening for ejection). This dynamic positioning ensures both safe tablet separation and efficient ejection operation.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The ejector acts as an intermediary mechanism between the storage container and the dispensing opening. By moving between blocking and receiving positions, it mediates between the need to prevent leakage and the need to enable ejection, ensuring both safety and operational efficiency.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Shape

If the receptacle is open-sided to allow observation, then transparency is improved, but structural integrity and reliable ejection may be compromised

Engineering Contradiction:
Improvereceptacle transparencyVSAvoidtablet ejection
Core Design Contradiction:
ShapeVSReliability

Solution Approach 1:

The receptacle is formed by segmenting the ejector into multiple walls (first, second, third ejector walls) that can be selectively positioned. This segmentation allows certain walls to be made transparent for observation while maintaining the structural framework needed for reliable ejection, combining transparency with functional integrity.

Inventive Principle:
Principle #1Segmentation

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

This design ensures reliable and clean ejection of tablets with cuboid or prismatic geometry and fruit gums, preventing jamming and allowing easy refilling while preventing misuse by ensuring only tablets are dispensed.

Implementation Method 1

which with the exception of the ejector base 13 is formed from an elastic material

Methodology Applied
Scientific EffectElasticity: Elasticity

Implementation Method 2

If the base of the receptacle is at least partially perforated and possibly beveled, misappropriation of the dispenser as a launching device for various objects, in particular by children, can be avoided. It is particularly advisable if the base of the receptacle is an inclined plane sloping down towards the opening

Methodology Applied
Scientific EffectGravity: Gravitation

AI summary

The invention relates to a tablet dispenser (1) for the single delivery of tablets (2). The tablet dispenser (1) comprises inter alia a housing (3), a storage chamber (4) for the tablets (2) adjoined by a separating device (5) for the tablets (2), and an ejector (6) arranged downstream of the separating device (5). The ejector (6) is associated with a longitudinal face of the housing (3), mounted such as to slide along said longitudinal face in a delivery chute (8) in the housing (3), and displaceable against the force of a spring and in a manner limited by stops from a delivery position blocking an opening (10) in the housing between the separating device and delivery chute (8) into an uptake position retracted into the delivery chute and unblocking the opening (10). To provide advantageous delivery conditions for the tablets (2), the ejector (6) according to the invention has a recess (11) for one tablet (2), wherein the recess (11) is spanned by at least three ejector walls (12, 12') and an ejector base (13).
