Press-fit Button Snap-catch Mechanism for Medical Base
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current fixing/releasing mechanisms for portable medical equipment are inconvenient to operate and prone to damaging the equipment during removal due to manual operation and the use of clamps that apply impact forces.
Innovation Solution
A fixing/releasing mechanism featuring a press-fit button, snap catch mechanism, and transmission mechanism that allows for automatic coupling and decoupling of medical apparatuses to a base, utilizing a lock hook with a buffer and elastomer to absorb impact and prevent damage, along with side mounting guide rails for improved positioning and impact buffering.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual operation with clamps is used to fix the medical apparatus to the base, then the fixing mechanism can be simple in structure, but the operation convenience deteriorates and the apparatus may be damaged during removal
Solution Approach 1:
The fixing mechanism enables self-service operation through the snap-fit design with protrusion and recess. When the medical apparatus is placed on the base, the protrusion automatically engages with the recess without requiring manual operation, achieving self-fixing functionality that improves ease of operation while maintaining structural simplicity
Solution Approach 2:
The invention replaces the traditional manual clamp mechanism with a snap-fit mechanical system consisting of protrusion, recess, and elastic component. This substitution eliminates the need for manual clamping operations while providing automatic fixing and release capabilities through the interaction of the protrusion and recess structures
2Reliability
If clamps are used to fix the medical apparatus to the base, then the fixing mechanism can be simple, but the apparatus may be damaged by impact force during removal
Solution Approach 1:
The elastic component is pre-installed in the fixing mechanism to provide cushioning before damage can occur. When the medical apparatus is removed from the base, the elastic component absorbs the impact force generated by the disengagement of the protrusion and recess, preventing damage to the apparatus beforehand
Solution Approach 2:
The invention converts the harmful impact force generated during removal into a beneficial cushioning effect. The elastic component transforms the sudden impact into gradual energy absorption, turning the potentially damaging force into a protective mechanism that safeguards the medical apparatus
3Extent of automation
If a snap-fit mechanism with lock hook is used, then the mounting process becomes stable and automatic, but the device complexity increases
Solution Approach 1:
The invention merges multiple functions into a unified snap-fit mechanism. The protrusion, recess, and elastic component work together as an integrated system that simultaneously provides automatic coupling, secure fixing, and impact absorption, achieving high automation without proportionally increasing complexity
Solution Approach 2:
The snap-fit mechanism with protrusion and recess serves multiple functions: automatic coupling when the apparatus is placed on the base, secure fixing during operation, and controlled release during removal. This multi-functionality achieves high automation while maintaining reasonable structural complexity
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 convenient, stable, and damage-free mounting and removal of medical equipment by automatically adjusting the lock hook mechanism and providing effective impact buffering, enhancing operational efficiency and equipment safety.
Implementation Method 1
a lock hook buffer and a lock hook elastomer; upon mounting, said lock hook buffer is fixed on the unit where the fixing/releasing mechanism is mounted; said lock hook buffer having a top portion being increasingly rising multiple planes and exposed on the front surface of the mounted unit to buffer the impact generated when the lock hook of the snap catch mechanism releases the other unit
Implementation Method 2
a press-fit button which, when under a pressure, moves in a direction of the force and automatically returns to the original position when the applied force disappears
