Testing Device for Dropper Dispensers with Downward Discharge
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing testing devices are not well-suited to examine drop dispensers, particularly those with downward-oriented discharge openings, as they lack the capability to actuate and position these dispensers in a reproducible manner, which is essential for evaluating their discharge behavior effectively.
Innovation Solution
A testing device designed to receive and actuate drop dispensers with downward-oriented discharge openings, featuring a receiving device that allows for adjustable positioning and an actuating device with movable actuators that simulate human actuation, enabling examination of drop dispensers in various orientations and facilitating the removal of residual drops.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing testing devices are used to examine dropper dispensers, then general dispenser examination is possible, but the devices cannot reproducibly position and actuate dropper dispensers with downward-oriented discharge openings
Solution Approach 1:
The receiving device incorporates a swiveling mechanism that allows the dropper dispenser to be positioned at adjustable angles, enabling the discharge opening to be oriented downward while maintaining reproducible positioning. This dynamic adjustment capability resolves the contradiction by adapting the fixed testing device to accommodate variable dispenser orientations.
Solution Approach 2:
The testing device is designed with a universal receiving device that can accommodate different types of dispensers, including dropper dispensers with downward-oriented discharge openings. The actuating device is configured to work with multiple dispenser mechanisms, making the testing device versatile enough to examine various dispenser types while maintaining reliable and reproducible testing conditions.
2Measurement precision
If dropper dispensers are positioned with downward-oriented discharge openings for examination, then discharge behavior can be evaluated, but the device complexity increases due to specialized receiving and actuating mechanisms
Solution Approach 1:
The testing device is divided into separate functional modules: a base unit, a swiveling receiving device, and an actuating device. This segmentation allows each component to be optimized for its specific function while maintaining overall system simplicity. The receiving device handles positioning, the actuating device handles actuation, and the base unit provides structural support and measurement capabilities.
Solution Approach 2:
The swiveling mechanism acts as an intermediary between the fixed base and the dropper dispenser, allowing the dispenser to be positioned at the desired angle without requiring complex adjustment mechanisms. This intermediary element simplifies the overall device complexity while enabling precise discharge behavior evaluation.
3Device complexity
If manual examination methods are used for dropper dispensers, then device complexity is minimized, but measurement precision and reproducibility are insufficient
Solution Approach 1:
The testing device is designed to be self-actuating through an automated actuating device that can reproduce manual actuation forces and motions. This self-service capability eliminates the need for complex manual operation while maintaining measurement precision. The device can automatically position and actuate the dropper dispenser, providing consistent and reproducible results.
Solution Approach 2:
Manual mechanical actuation is replaced with an automated actuating device that uses controlled mechanical forces to replicate human hand movements. This substitution maintains the simplicity of mechanical operation while significantly improving measurement precision and reproducibility through automated control and consistent force application.
