Breathing Tube Sensor Connecting Component Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connecting components for breathing tubes with gas flow sensors require complex design measures for proper alignment and centering, making it difficult to insert sensors in the preferred direction and ensuring accurate gas flow and temperature measurement.
Innovation Solution
A connecting component with a conical mounting sleeve and a wall section extending flush with the grip element, which prevents rotation and allows for easy alignment of the sensor's temperature-measuring elements, using either a projection or centering pins to secure the sensor's position, and allowing for adaptability with commercially available sensors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a sensor connection is inserted into a mounting sleeve with static friction, then the sensor is held in position, but the sensor cannot be reliably centered or aligned in the preferred direction
Solution Approach 1:
A centering element is introduced as an intermediary component between the sensor connection and the mounting sleeve. This centering element features an outer contour that interfaces with the mounting sleeve and an inner contour that interfaces with the sensor connection, thereby mediating the alignment and centering process while the static friction between the mounting sleeve and sensor connection maintains positional reliability
2Manufacturing precision
If design measures are added to both the sensor and mounting sleeve for centering, then the sensor can be centered in relation to the connecting component, but the device complexity increases
Solution Approach 1:
The centering function is merged into a single centering element that combines the centering and alignment functions. This centering element integrates the outer contour for interfacing with the mounting sleeve and the inner contour for interfacing with the sensor connection, thereby achieving precise centering while reducing the overall number of separate components and simplifying the device structure
