Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current droplet levitation methods expose users to high voltages and lack modifiability, posing safety risks and limiting their applicability due to fixed configurations and uncontained high voltage electrodes.
Innovation Solution
The Dual Balance Electrodynamic Trap (DBET) features a droplet dispenser holder that maintains a safe distance from electrodes, adjustable rod holders for modifiability, and a chamber that encloses all high voltage components, allowing for safe generation and levitation of charged droplets while preventing user exposure to lethal voltages and enabling customizable configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If high voltage electrodes are used for droplet levitation, then droplet levitation is achieved, but user safety is compromised due to exposure to lethal voltages
Solution Approach 1:
The device is divided into separate functional zones: a high voltage electrode chamber that is physically isolated from the user interface, and a user interaction zone where droplet dispensing occurs. The chamber acts as a segmented barrier containing the harmful high voltage elements while allowing the useful levitation function to operate independently in a safe manner.
Solution Approach 2:
A non-conductive chamber or enclosure serves as an intermediary barrier between the high voltage electrodes and the user. This intermediary structure allows the electric field to function for droplet levitation while simultaneously providing electrical isolation and protection to the user from direct exposure to lethal voltages.
2Device complexity
If fixed configuration designs are used, then device simplicity is maintained, but adaptability and versatility are limited
Solution Approach 1:
The device incorporates adjustable and reconfigurable elements within its structure, allowing the configuration to be dynamically modified for different experimental needs. Components such as adjustable electrode positions, removable chamber sections, or reconfigurable mounting fixtures enable the system to adapt to various droplet sizes, shapes, and experimental conditions while maintaining overall structural simplicity.
Solution Approach 2:
The device is designed with universal features that allow it to perform multiple functions and accommodate different experimental configurations. Standardized interfaces, interchangeable components, and modular architecture enable the same basic structure to support various droplet levitation experiments, making the device versatile without requiring complex specialized designs for each application.
3Reliability
If high voltage electrodes are exposed for droplet charging, then droplet levitation is enabled, but equipment damage risk increases due to potential contact
Solution Approach 1:
The device incorporates protective barriers and isolation chambers that are built into the design before any potential contact can occur. These pre-installed protective structures act as cushions or buffers that prevent direct contact between the high voltage electrodes and external objects, thereby protecting expensive equipment from damage while allowing the droplet charging function to operate effectively.

AI summary
A dual balance electrode trap having an outer chamber, a droplet dispenser holder removably coupled to the top surface of the outer chamber, and a rod holder having a central opening and four peripheral openings that are sized and shaped to allow four respective quadrupole metal rods to pass therethrough. The droplet dispenser holder has a top surface, a bottom surface, and a through hole that extends from the dispenser holder top surface to the droplet dispenser bottom surface. The through hole has a larger diameter portion adjacent to the top surface and a smaller diameter portion adjacent to the bottom surface, thereby preventing a droplet dispenser distal tip from extending entirely through the hole and contacting electrodes in the DBET. The rod holder is configured to be removably coupled to the quadrupole metal rods so that a location of the rod holder relative to the metal rods is adjustable.
