Rotatable Ventilator Housing for Ergonomic Emergency Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Emergency ventilator devices face challenges in being optimally deployed and operated in unprepared operational environments, such as accident sites, due to varying setting heights and hectic conditions, which can lead to operational difficulties and increased risk of interference from rescue personnel.
Innovation Solution
A ventilator device with a rotatable frame that accommodates the device housing and input/output device, allowing for orientation to minimize operator strain and reduce the risk of collision with other personnel, while maintaining a compact and secure design with functional interfaces aligned along the axis of rotation for easy handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the ventilator device is designed as a portable device with fixed housing, then it can be easily transported, but it cannot be optimally oriented in diverse operational environments
Solution Approach 1:
The device housing is made rotatable relative to the frame about an axis of rotation, allowing the housing to be dynamically reoriented to different angular positions. This enables the ventilator to adapt to various operational environments and setting heights while maintaining a relatively simple overall structure.
Solution Approach 2:
The ventilator device is divided into two main segments: a fixed frame and a rotatable device housing. This segmentation allows the housing to be independently rotated relative to the frame, providing adaptability without requiring the entire device structure to be complex or movable.
2Ease of operation
If the input/output device is fixed on the housing, then the structure is simple, but the operator cannot adjust the orientation to reduce strain
Solution Approach 1:
The input/output device is mounted on the rotatable housing, inheriting the rotational capability. This allows the operator to rotate the housing to orient the input/output device at an ergonomically optimal angle, reducing operator strain while maintaining structural simplicity through the shared rotation mechanism.
3Stability of the object's composition
If the ventilator device is placed on the ground at accident sites, then it is stable, but the operator may experience strain due to suboptimal orientation
Solution Approach 1:
The rotatable housing allows the operator to adjust the orientation of the ventilator device after stable placement on the ground. The device can be rotated to optimal viewing and operating angles without requiring movement or relocation, thus maintaining stability while reducing operator strain.
4Volume of moving object
If the device housing is made compact, then it is portable, but the functional interfaces may be difficult to access
Solution Approach 1:
The rotatable housing enables the functional interfaces to be oriented toward the operator by rotation. This allows the device to maintain a compact size while ensuring that interfaces remain accessible through angular adjustment, solving the conflict between compactness and accessibility.
