Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing particulate dispensers fail to adequately deaggregate and agitate particulates, leading to inconsistent dosing and clumping issues, particularly in medicament delivery, which requires a solution for thorough agitation and accurate dosage independent of patient variables.
Innovation Solution
A dispenser design featuring a container for a fluid in fluidic communication with a particulate chamber, using turbulent flow agitation mechanisms, such as cyclonic or vertical flow, to deaggregate and mix particulates with a pressurized gas or liquid, ensuring consistent delivery without exposure to the particulate during storage or transit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional dispensers are used for particulates, then the device structure is simple, but the particulate is not adequately agitated or deaggregated leading to inconsistent dosing
Solution Approach 1:
The patent employs a fluid jet system where pressurized gas or liquid flows through channels to create turbulent flow within the chamber. This pneumatic/hydraulic approach generates strong agitation forces that effectively deaggregate and mix particulates without requiring complex mechanical moving parts, thereby achieving precise dosing through fluid dynamics rather than mechanical complexity
Solution Approach 2:
The turbulent flow generated by the fluid jet creates intense mixing and agitation patterns within the chamber that function similarly to mechanical vibration. The chaotic flow patterns and eddies produced by the jet impingement provide continuous deaggregation and redistribution of particulates, ensuring consistent dosing through flow-induced mixing rather than traditional mechanical agitation mechanisms
2Stability of the object's composition
If particulate is stored in a compact container, then the device is portable and lightweight, but the particulate tends to clump during storage and transit
Solution Approach 1:
The system uses a lightweight pressurized gas reservoir connected to fluid channels that terminate in the particulate chamber. Upon actuation, the pressurized gas creates a high-velocity jet that instantly deaggregates clumped particulates and maintains them in a fluidized state during dispensing. This pneumatic approach maintains particulate flowability without adding significant weight compared to mechanical agitation systems
Solution Approach 2:
The fluid jet acts as an intermediary medium between the pressurized gas source and the particulate material. The fluid carries the momentum and energy from the gas reservoir to the particulates, using the fluid's kinetic energy to deaggregate and fluidize the particulates without requiring direct mechanical contact or heavy agitation mechanisms
3Manufacturing precision
If sufficient agitation is provided to deaggregate particulate, then consistent dosing is achieved, but the device complexity increases
Solution Approach 1:
The patent uses a fluid jet impingement system where pressurized fluid flows through defined channels and terminates in the particulate chamber, creating intense localized turbulent flow. This pneumatic/hydraulic mechanism generates sufficient agitation and deaggregation forces through fluid dynamics alone, eliminating the need for mechanical stirrers, vibrators, or other complex agitation mechanisms while maintaining dosing consistency
Solution Approach 2:
The invention replaces traditional mechanical agitation systems with a fluid-based pneumatic/hydraulic system. Instead of using motors, gears, or mechanical vibrators to agitate particulates, the system uses pressurized fluid flow to create turbulent mixing patterns. This substitution eliminates complex mechanical components while achieving the required agitation intensity for consistent dosing
