Portable Dispenser Shaking Detection for Mixing Ratio Accuracy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Pharmaceutical medium dispensers often fail to maintain the desired mixing ratio of components due to separation over time, and users frequently neglect to shake the dispensers properly before use, leading to inadequate mixing.
Innovation Solution
A medium dispenser equipped with a detection device that includes a haptic, optical, or acoustic output system to inform users of sufficient shaking, featuring an indicator medium that changes appearance when shaken, ensuring the desired mixing ratio is achieved.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If users rely on vague instructions for use regarding shaking duration, then the device complexity remains low, but the reliability of achieving proper mixing ratio deteriorates
Solution Approach 1:
The patent implements feedback mechanisms including sensors that detect shaking motion and provide real-time information to the user through displays or indicators. This feedback loop allows users to know when sufficient shaking has occurred, ensuring proper mixing ratio without requiring complex manual judgment about shaking duration.
Solution Approach 2:
The patent replaces mechanical/instruction-based shaking guidance with electronic detection and information systems. Sensors, microprocessors, and display devices substitute for physical shaking indicators, providing automated detection of shaking adequacy and eliminating the need for users to interpret vague textual instructions.
2Duration of action of stationary object
If the medium is stored for longer periods in the reservoir, then the convenience of delayed dispensing is improved, but the homogeneity of the medium deteriorates due to component separation
Solution Approach 1:
The patent requires shaking action before dispensing to pre-mix the components and restore homogeneity. This preliminary mixing action ensures that components are properly combined before use, counteracting the separation that occurs during storage periods.
Solution Approach 2:
The patent implements periodic shaking requirements at dispensing intervals to maintain medium homogeneity. By requiring users to shake the device before each use after storage, the system periodically restores proper mixing, preventing permanent composition degradation during extended storage periods.

AI summary
1. Portable medium dispenser for discharging liquid, pasty, or powdery media. 2.1. The invention relates to a portable medium dispenser (10) for discharging liquid, pasty, or powdery media, comprising a housing (12) having a discharge opening (14), a medium store (16) for accommodating the medium before discharge, and an operating handle (16a), by means of which a conveying process can be effected, during which medium is conveyed from the medium store (16) to the discharge opening (14). 2.2. According to the invention, the dispenser (10) has a detecting device (220) for detecting a shaking movement, which detecting device comprises an optical or acoustic output device (230a, 230b) and is designed in such a way that the detecting device transfers the output device from a first state to a second state in reaction to manual shaking of the dispenser (10). 2.3. The invention further relates to the use thereof for media having two components, such as suspensions and emulsions.
