Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional medicine infusion regulators struggle to finely control the flow rate of liquid medicine, are inconvenient to install, and have a limited application scope, often leading to inconsistent and potentially harmful medication delivery.
Innovation Solution
A regulator comprising a housing with a membrane member, lever, and resilient plate that adjusts to block or allow the flow of liquid medicine based on pressure, ensuring a uniform flow rate by changing the shape of the membrane member and leveraging the resilience of the resilient plate to prevent excessive flow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a conventional regulator is rotated to change the cross-sectional area of a tube to regulate flow rate, then the flow rate can be adjusted, but it is difficult to finely regulate the flow rate and the structure is complicated
Solution Approach 1:
The patent changes the regulatory parameter from mechanical rotation of tubes to pressure control via a resilient plate. By adjusting the resilience (pressure) of the plate, the membrane member deforms to precisely control the flow passage cross-sectional area, achieving fine flow rate regulation without complex mechanical rotation mechanisms
Solution Approach 2:
The patent replaces the mechanical rotation system with a pressure-based control system. Instead of rotating tubes to change cross-sectional area, a resilient plate applies pressure to deform a membrane member, substituting mechanical rotation with elastic deformation controlled by pressure adjustments
2Stability of the object's composition
If a pressure regulating valve is added to uniformly regulate gas pressure, then the flow rate can be controlled consistently, but the structure becomes more complicated and manufacturing cost increases
Solution Approach 1:
The patent merges the pressure regulation function and flow control function into a single integrated structure. The resilient plate simultaneously regulates pressure and controls the membrane deformation, eliminating the need for separate pressure regulating valves and reducing overall structural complexity
Solution Approach 2:
The resilient plate performs multiple functions: it acts as both a pressure regulation element and a flow control actuator. By deforming the membrane member through pressure application, it uniformly controls the flow rate while maintaining consistent pressure, achieving multi-functionality in a single component
3Reliability
If a pressure regulating valve is installed inside the gas supply apparatus, then flow control is improved, but it is inconvenient to install and manufacturing cost increases
Solution Approach 1:
The patent combines the flow control mechanism with the existing regulator body structure. The resilient plate and membrane member are integrated into the housing, eliminating the need for separate pressure regulating valves and reducing installation complexity while maintaining reliable flow control
4Ease of manufacture
If the flow rate of liquid medicine is not consistently injected, then installation is simpler, but there is a risk of shock and patient safety is compromised
Solution Approach 1:
The patent implements a feedback mechanism where the resilient plate responds to pressure changes from the liquid medicine flow. When flow rate increases, pressure builds up, deforming the membrane and reducing the flow passage area, automatically maintaining consistent flow rate and preventing patient shock without complex additional components
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The regulator effectively maintains a consistent flow rate of liquid medicine, preventing excessive infusion and ensuring uniform delivery, while being easily installable in various medicine injectors and intravenous bottles, thus enhancing patient safety and reducing manufacturing costs.
Implementation Method 1
a membrane member which receives a pressure of a liquid medicine discharged via the medicine flow passage from the inlet to the outlet and changes in shape according to a flow rate of the liquid medicine discharged via the medicine flow passage from the inlet to the outlet
Implementation Method 2
a resilient plate which is located between the membrane member and the lever and whose resilience is adjusted at a predetermined level so as to allow the pressure of the liquid medicine received through the membrane member to be delivered to the outlet side extension portion of the lever only when the flow rate of the liquid medicine exceeds a predetermined flow rate needed for a patient
