Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In emergency response vehicles and healthcare settings, existing oxygen switcher systems face challenges with space efficiency, vulnerability of pressure gauges to impact, and difficulties in monitoring gas pressure, leading to potential leaks and risks during critical interventions.
Innovation Solution
A gas switcher with integrated manometer positioned on the switcher, where the manometer remains constant and aligned with the knob, providing protection and easy monitoring, allowing for standalone or integrated use with collectors, reducing material usage and enhancing durability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the pressure gauge (manometer) is located on the collector (distributor), then the collector can provide gas distribution function, but the collector becomes longer and uses more material
Solution Approach 1:
The patent combines the manometer and switcher into an integrated assembly that can be mounted on the collector. This merging of components achieves space efficiency by consolidating multiple functions (pressure measurement and gas switching) into a single unit, reducing the overall collector size and material usage while maintaining system functionality
2Measurement precision
If the pressure gauge (manometer) is positioned on the collector, then it can monitor gas pressure, but it becomes more unprotected and vulnerable to impacts
Solution Approach 1:
The switcher knob is designed to serve a dual function: it operates the gas switching mechanism and simultaneously acts as a protective shield for the manometer. This preliminary design decision ensures that the manometer is protected from impacts before any damage can occur, while maintaining clear pressure visibility for monitoring
3Ease of manufacture
If the pressure gauge (manometer) is not at an easily visible angle on the collector, then it can be installed on the collector, but it causes difficulties for medical teams during gas pressure control
Solution Approach 1:
The manometer is designed with rotational freedom within a specific angular range (0-360 degrees), allowing it to be dynamically positioned at the optimal viewing angle. This dynamic positioning capability ensures that medical teams can always view the pressure gauge at an easily visible angle, while the mounting system provides installation flexibility through adjustable positioning mechanisms
4Loss of substance
If the manometer and switcher are integrated as a single piece, then material is saved and space is reduced, but the manufacturing complexity increases
Solution Approach 1:
The integrated manometer-switcher assembly is designed as a modular unit that can be manufactured separately and then mounted on the collector as a complete assembly. This segmentation approach allows each component to be optimized for its specific function during manufacturing, while the final integration achieves material savings and space efficiency by eliminating the need for separate mounting structures and connections
