Universal Cartridge Dispenser with Multi-Level Actuation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dispenser systems require separate devices for different types of media, leading to increased production and storage costs, and making it difficult to switch between media types, limiting customer flexibility.
Innovation Solution
A universal dispenser system designed as a common part system that can accommodate various media types, with a cartridge holder and storage cartridges optimized for consistent actuator and abutment distances, and an actuating device with multiple pressure-exerting areas to accommodate different dispensing devices, allowing for easy adaptation to different media.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separate dispenser device is constructed for each type of medium, then the dispenser can reliably dispense the specific medium, but the production costs, storage costs increase and it becomes difficult to convert the dispenser system to another medium
Solution Approach 1:
The dispenser system is designed with a universal cartridge receptacle that can accommodate multiple types of storage cartridges (liquid, foam, aerosol, paste) through standardized holding means. The actuating device features multiple pressure-exerting areas that can work with different dispensing device configurations, enabling a single dispenser housing to reliably dispense various media types without requiring complete system replacement
Solution Approach 2:
The dispenser system is divided into separable components: a permanent housing with actuating device and cartridge receptacle, and replaceable storage cartridges containing different media types. This segmentation allows the customer to keep the base dispenser system and only replace the storage cartridge when changing media types, maintaining reliability while enabling easy conversion
2Reliability
If a separate dispenser device is constructed for each type of medium, then the dispenser can reliably dispense the specific medium, but the production costs and storage costs increase
Solution Approach 1:
The dispenser housing, actuating device, and cartridge receptacle are designed as universal components that can work with multiple types of storage cartridges. This allows a single base unit to be manufactured and sold, reducing production costs compared to manufacturing separate dispensers for each medium type, while maintaining reliable dispensing performance across different media
Solution Approach 2:
The patent combines the functions of multiple specialized dispensers into a single universal dispenser system. The housing integrates the cartridge receptacle, actuating device with multiple pressure-exerting areas, and medium outlet in one unit that can accommodate various storage cartridge types, thereby reducing overall production costs and storage requirements
3Device complexity
If the actuating device has a fixed pressure-exerting area, then the device structure is simple, but it cannot accommodate different types of storage cartridges with different dispensing device lengths
Solution Approach 1:
The actuating device is equipped with multiple pressure-exerting areas at different positions, allowing it to adapt to storage cartridges with different dispensing device lengths. Each pressure-exerting area can be selectively engaged depending on the cartridge type inserted, enabling the same actuating device structure to work with varied cartridge configurations without compromising adaptability
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
Enables the use of a single dispenser system for pasty, liquid, sprayable, and foamed media, reducing production and storage costs, and allowing for easy conversion between media types without the need for extensive hardware changes.
Implementation Method 1
a compressive force presses on a dispensing device, mostly in the form of a pump, whereby the portion of the medium can usually be dispensed downwards
Implementation Method 2
the cartridge receptacle comprises at least one holding means that is connected to the housing and on which the bearing surface of the storage container can be placed to support the weight of the storage cartridge

AI summary
The invention relates to a dispenser system comprising a housing (8) into which a reservoir cartridge (1) that consists of a reservoir container and a distribution device (2) is inserted. Said housing (8) comprises an actuation device (6) that acts upon the distribution device (2) in such a manner that when pressure is applied to the actuation device, it dispenses a portion of the medium to the distribution device. Known dispenser systems have the disadvantage that a separate dispenser is required for each medium. The aim of the invention is to provide an identical part dispenser system. As a result, a connection element (5) compensating the various geometries of the distribution device (2) is connected to the distribution device (2). Also, the actuation device (6) comprises pressure transmission surfaces arranged at various levels and which cooperate with the surfaces of the distribution device (2) receiving the pressure, the different surfaces interacting with each other according to the used reservoir cartridge (1).
