Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cricothyrotomy devices often slip out of place during use or are complex, making them less suitable for emergent or training situations.
Innovation Solution
A cricothyrotomy device featuring a port with an elongated cannula portion and a base cannula portion, coupled with a ring lock that secures the device in place, enhancing stability and ease of use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing cricothyrotomy devices are used, then the procedure can be performed, but the devices slip out of place during use reducing reliability
Solution Approach 1:
The device is divided into distinct functional segments: a port component with cannula portions for insertion, and a separate ring lock component for securing. This segmentation allows each part to be optimized independently - the port for insertion and the ring lock for stable positioning, resolving the contradiction between ease of use and stability.
Solution Approach 2:
The tapered end of the elongated cannula portion is pre-formed to facilitate easy insertion through the cricothyroid membrane before the device is fully deployed. This preliminary shaping action enables quick initial placement, while subsequent engagement of the ring lock provides the needed stability, addressing both speed and reliability requirements.
2Productivity
If existing cricothyrotomy devices are used, then the procedure can be performed, but the devices are complex making them less suitable for emergent situations
Solution Approach 1:
The locking function is extracted as a separate ring lock component that can be independently attached to the port. This extraction simplifies the main port structure for faster insertion, while the separate ring lock provides the necessary securing function, reducing overall device complexity without sacrificing functionality.
Solution Approach 2:
The ring lock component is designed to nest around the port structure, with the lock tabs fitting into the port body. This nested configuration allows the device to be compact and simple during insertion, then provides robust locking engagement once positioned, achieving both simplicity and reliability.
3Reliability
If a secure locking mechanism is added to prevent slipping, then device stability improves, but device complexity increases
Solution Approach 1:
The locking tabs are integrated directly into the port structure, merging the locking function with the existing port design. This integration eliminates the need for separate complex locking components, achieving reliable device stability through a unified, simpler structure that combines insertion and locking functions.
Solution Approach 2:
The ring lock mechanism is designed to engage automatically with the port structure through the lock tabs and notches, providing self-securing functionality. Once the device is inserted, the ring lock naturally engages with the port, providing reliable stability without requiring complex manual operation or additional components.
