Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ECG leads often become tangled during use and storage, making retrieval and storage inconvenient.
Innovation Solution
A retractable ECG lead device with a spool mechanism that allows leads to be easily extended and retracted, featuring a main body with spool rods and wire apertures for each lead, enabling automatic wrapping and storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional ECG leads are used without a spool mechanism, then the leads can be easily accessed, but they become tangled during use and storage
Solution Approach 1:
The patent implements a spool mechanism that transforms the static lead storage into a dynamic system. The spool can rotate to pay out leads during use and rewind them during storage, allowing the lead arrangement to adapt between extended and retracted states. This dynamic mechanism prevents tangling by controlling the lead path through the spool's rotational motion.
Solution Approach 2:
The spool acts as an intermediary device between the leads and the user/environment. It mediates the interaction by providing a controlled interface for lead deployment and retraction. The spool's rotation controls the lead flow, preventing direct contact and tangling between multiple leads while maintaining easy accessibility when needed.
2Adaptability or versatility
If multiple ECG leads are stored together, then all leads are available, but they become entangled and difficult to manage
Solution Approach 1:
The patent divides the lead management system into separate spool units, each dedicated to a specific lead. This segmentation prevents leads from becoming entangled with each other while maintaining all leads in one consolidated device. Each spool independently manages its associated lead, simplifying the overall management complexity despite having multiple leads available.
3Ease of operation
If leads are kept extended for easy access, then they are readily available, but they occupy more space and can become tangled
Solution Approach 1:
The spool mechanism enables the lead storage volume to dynamically adjust based on usage needs. When leads are needed, the spool rotates to pay them out, increasing the effective volume. When not in use, the spool rewinds the leads, minimizing the volume. This dynamic volume adjustment maintains accessibility while reducing space occupation during storage.
