CPR Chest Compression Clamp With Movable Stopper
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mechanical CPR devices face issues with accidental locking of support legs due to unintentional contact, leading to time wastage during assembly, which can compromise the timely delivery of chest compressions.
Innovation Solution
A rotatable claw mechanism with a stopper ensures the support leg is always lockable to the base member, preventing accidental locking by engaging only when properly attached, and features a release mechanism for easy detachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a locking mechanism is used to secure the support leg to the base member, then the assembly becomes secure and stable, but accidental locking can occur leading to time wastage during assembly
Solution Approach 1:
A movable stopper acts as an intermediary element between the locking rod and the receiving channel. The stopper temporarily blocks the receiving channel to prevent accidental locking, but allows intentional locking when the locking rod is properly positioned. This mediator resolves the contradiction by enabling secure locking while preventing premature or accidental engagement.
2Productivity
If the clamp mechanism is always lockable for quick assembly, then assembly speed increases, but accidental locking may occur due to unintentional contact
Solution Approach 1:
The movable stopper provides preliminary anti-action by preemptively blocking the receiving channel before the locking rod can accidentally engage. This prevents harmful accidental locking from occurring in the first place, while still allowing quick intentional assembly when the stopper is properly displaced by the locking rod.
3Object-affected harmful factors
If a stopper mechanism is added to prevent accidental locking, then accidental locking is prevented, but the device complexity increases
Solution Approach 1:
The stopper function is extracted as a separate, movable component rather than being integrated into the main locking structure. This modular approach prevents accidental locking while keeping the overall mechanism relatively simple and easy to manufacture.
4Ease of operation
If the support leg requires resetting mechanisms to correct accidental locking, then accidental locking can be corrected, but the assembly process becomes more complex and time-consuming
Solution Approach 1:
The movable stopper design allows the mechanism to self-correct accidental locking situations. When the locking rod is properly positioned, it automatically displaces the stopper and completes the locking action, eliminating the need for separate resetting mechanisms or complex correction procedures.

AI summary
A cardiopulmonary resuscitation ("CPR") device has a clamp mechanism coupled with a support leg, structured to move between an unlocked position and a locked position to secure the support leg to a locking rod of a base member. The CPR device further includes a movable stopper comprising a strip-formed spring slidably coupled with the support leg and configured to translate between a barred position and an unbarred position relative to the clamp mechanism, the movable stopper preventing the locking rod from being received in the receiving channel of the when the movable stopper is in the barred position, and the movable stopper allowing the locking rod to be received in the receiving channel when the movable stopper is in the unbarred position, the movable stopper further receiving the pin of the barrel in a slot when the movable stopper is in the unbarred position.
