Deformable Valve Control for Child-Resistant Inhalable Pharmaceuticals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing inhalable fluid dispensing devices, such as vaporizers, lack effective mechanisms to prevent children from accessing and using them, posing a risk of accidental exposure to potentially harmful substances.
Innovation Solution
Implementing a deformable valve system in inhalable fluid dispensing devices that requires a predetermined force to open, exceeding the capabilities of children, ensuring compliance with safety standards set by Title 16 of the Code of Federal Rules (CFR) 1700.15, thereby preventing unauthorized access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a simple fluid pathway is used in inhalable fluid dispensing devices, then ease of operation is improved, but child safety is worsened
Solution Approach 1:
The patent changes the force parameter required to open the fluid pathway by implementing a deformable valve that requires a predetermined force exceeding child capabilities. This parameter change maintains ease of operation for adults while preventing child access, resolving the safety contradiction.
Solution Approach 2:
The patent implements a deformable valve system that dynamically responds to applied force. The valve transitions from a closed state (preventing access) to an open state (allowing flow) based on the force applied, enabling child safety while maintaining ease of operation for authorized users.
2Object-affected harmful factors
If a deformable valve requiring predetermined force is implemented, then child safety is improved, but device complexity is worsened
Solution Approach 1:
The patent uses a deformable valve made from flexible materials that can be deformed by applying force. This flexible structure provides child safety through force requirement while maintaining relatively simple device construction, mitigating the complexity increase.
Solution Approach 2:
The deformable valve system is self-regulating, automatically responding to applied force without requiring external control mechanisms. The valve opens or closes based on the force applied, eliminating the need for complex electronic controls or additional safety mechanisms.
3Object-affected harmful factors
If child resistant control is added to inhalable fluid dispensing devices, then child safety is improved, but ease of operation is worsened
Solution Approach 1:
The patent changes the force parameter threshold to differentiate between child and adult users. The predetermined force requirement acts as a simple threshold that children cannot meet but adults can easily exceed, providing child safety without complicating the operation for authorized users.
Applied Scientific Principles
