Chest Compression Belt Assembly With Sensor-Verified Couplings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mechanical chest compression devices for CPR often require inconvenient belt installation and may not ensure proper belt attachment, which can lead to inefficient operation and potential user safety hazards.
Innovation Solution
A belt-driven chest compression device with a platform housing drive components, where the compression belt is connected through releasably attachable couplings near the upper surface, allowing for easy belt removal and replacement without twisting, and includes a sensor system to ensure proper belt attachment before operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the drive spool is accessible from the bottom or posterior aspect of the device, then the belt can be secured to the drive spool, but the belt installation becomes inconvenient and requires lifting the device
Solution Approach 1:
The belt attachment mechanism is segmented into modular components: a drive spool with a slot, a spline with teeth that engage the slot, and a retaining structure. This segmentation allows the belt to be attached and detached independently from the main device body, enabling convenient belt installation without lifting the entire device while maintaining a relatively simple overall structure.
2Reliability
If the belt is tightly secured to ensure proper attachment, then safety is improved, but the belt becomes difficult to remove and replace
Solution Approach 1:
The belt attachment mechanism employs a dynamic retaining structure that can transition between engaged and disengaged states. The retaining component can be easily moved to release the spline from the slot for belt removal, and securely engaged for tight fixation during operation. This dynamic capability allows the system to switch between secure attachment and easy removal without compromising either reliability or ease of operation.
3Ease of operation
If the belt installation process is simplified, then ease of operation is improved, but proper belt attachment may not be ensured
Solution Approach 1:
The belt attachment mechanism incorporates a feedback feature where the spline's engagement with the slot provides tactile and visual confirmation of proper attachment. The retaining structure is designed to clearly indicate when the belt is securely fastened, ensuring that even during simplified installation processes, proper attachment is assured through immediate feedback to the operator.
