Shaped Cartridge Dispensing via Asymmetric Geometric Interfaces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing chemical product dispensing systems lack the ability to accurately differentiate and dispense various types of concentrated chemical products, leading to potential incorrect loading and dispensing of incompatible products, which can result in improper dilution and usage.
Innovation Solution
A dispensing system featuring shaped dispensing cartridges and receptacles with geometrically compatible cross-sections to ensure correct matching and prevent incorrect loading, using various geometric shapes such as hexagonal, cylindrical, and notched designs to correspond with specific types of chemical product concentrates, thereby ensuring accurate dispensing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional dispensing systems are used without geometric differentiation, then device complexity is reduced, but reliability deteriorates due to inability to prevent incorrect product loading
Solution Approach 1:
The patent applies asymmetry by giving each cartridge and its corresponding receptacle a unique geometric cross-section shape. This asymmetric design ensures that only the correct cartridge type can be loaded into the correct receptacle, preventing incorrect product loading while maintaining system reliability.
2Manufacturing precision
If geometrically shaped receptacles are implemented, then manufacturing precision is improved for accurate product dispensing, but device complexity increases due to multiple shaped components
Solution Approach 1:
Each receptacle is designed with a specific asymmetric geometric shape that corresponds to its designated cartridge type. This ensures that only cartridges with matching geometric profiles can be properly inserted and dispensed, thereby improving manufacturing precision for accurate product dispensing while using a manageable number of shaped components.
3Adaptability or versatility
If multiple shaped cartridges are used for different product types, then adaptability is improved, but ease of operation deteriorates due to need to identify correct shapes
Solution Approach 1:
The asymmetric geometric design of cartridges and receptacles provides inherent visual and tactile differentiation, making it easy for operators to identify and select the correct cartridge type for each receptacle. This improves ease of operation while maintaining the system's adaptability to handle multiple chemical product types.

AI summary
Dispensing systems utilize shaped cartridges to dispense one or more different types of chemical product concentrates. The chemical product concentrates may include, for example, tablets, capsules, encapsulated pellets or loose powders, or any other unit dose form factor. The chemical product concentrates may also include loose pellets or loose powders, or any other form of chemical product concentrate. The chemical product concentrates are dispensed from a plurality of shaped dispensing cartridges having different geometrically shaped cross-sections. Each cross-sectional shape may correspond to a different type of chemical product concentrate. Dispensing units include one or more shaped receptacles, each having a different geometrically shaped cross-section sized to receive a geometrically compatible one of the shaped dispensing cartridges. The dispensing units may further include shaped dispensing fitments sized to receive a geometrically compatible neck of a product container.
