Emergency Ventilator Wall Holder With Low-Force Locking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing emergency ventilator wall holders require significant force to secure and release the ventilator, complicating emergency operations.
Innovation Solution
A wall holder design with an engagement preparation position distinct from the engagement position, utilizing a pre-tensioned locking structure and actuation body to facilitate secure and rapid attachment and detachment of the ventilator with reduced force.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a catch bolt is used to secure the emergency ventilator arrangement, then the ventilator is held securely, but significant force is required to overcome the holding force for mounting and releasing
Solution Approach 1:
The locking process is segmented into two distinct phases: an engagement preparation position where the locking structure is retracted to allow easy insertion, and an engagement position where the locking structure extends to secure the ventilator. This segmentation allows the locking and unlocking forces to be applied at different stages, reducing the overall force requirement.
Solution Approach 2:
The locking structure is pre-positioned in an engagement preparation position before the ventilator is fully inserted. This preliminary positioning reduces the initial resistance during insertion and allows the locking engagement to occur gradually, minimizing the peak force required for mounting and releasing.
2Reliability
If a complicated locking device with latch pins and Bowden cables is used, then the ventilator can be secured, but the device complexity increases
Solution Approach 1:
The complex Bowden cable mechanism and multiple latch pins are replaced by a simplified locking structure that integrates the locking function into a single movable component. This extraction of unnecessary complexity maintains reliable locking while significantly reducing device complexity.
Solution Approach 2:
Multiple locking functions (latch engagement, spring pre-tensioning, and actuation mechanism) are merged into a single integrated locking structure. This consolidation eliminates the need for separate Bowden cables and multiple independent latch pins, reducing overall device complexity while maintaining secure locking capability.
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
Enables secure and rapid attachment and detachment of emergency ventilators with minimal effort, ensuring quick deployment and reducing the risk of accidental disengagement during emergencies.
Implementation Method 1
The displaceable catch bolt exhibits on its side facing away from the basic structure an insertion chamfer, against which a section of the emergency ventilator arrangement can come into abutment and which through this section under further approach of the emergency ventilator arrangement to the basic structure can be translationally displaced
