AED Electrode Tray with Affixed Release Liner
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional automated external defibrillator (AED) electrode pads require multiple steps for setup, increasing the time to administer treatment and risking user error due to the need to break adhesive and manage release liners, which can delay critical cardiac care.
Innovation Solution
A system featuring a tray with electrode pads and release liners affixed to it, allowing for easy removal of pads while keeping the liner attached to the tray, reducing steps and potential for error by exposing the electrode contact structure directly for application, and enabling quick electrical connection to the AED.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If traditional electrode pads with separate release liners are used, then the electrode pads can be stored and protected, but multiple steps are required for setup including breaking adhesive and managing release liners, increasing the time to administer treatment
Solution Approach 1:
The release liner is merged with the tray structure by affixing it to the tray, creating an integrated system where the liner becomes part of the storage assembly rather than a separate component that needs to be handled independently during setup
Solution Approach 2:
The release liner is pre-affixed to the tray during manufacturing, preparing the system in advance so that during emergency use, the user only needs to pull the electrode pad without worrying about separate release liner management
2Reliability
If traditional electrode pads require breaking adhesive and managing separate release liners, then the pads can be securely stored, but this increases the potential for user error and delays treatment
Solution Approach 1:
The system is segmented into distinct functional zones: the electrode pad itself, the affixed release liner, and the tray structure. This segmentation allows each component to have its own optimized attachment mechanism, with the liner firmly attached to the tray while the pad can be easily separated from the liner area
Solution Approach 2:
The release liner acts as an intermediary between the electrode pad and the tray, providing a controlled interface that secures the pad during storage but allows easy removal during use through a simple pulling motion
3Productivity
If electrode pads are quickly removable from the tray, then treatment time is reduced, but the wires may become disorganized or damaged during removal
Solution Approach 1:
The wire is nested within the cavity of the tray, with the wire positioned inside the recessed space. This nesting arrangement protects the wire from damage during pad removal while allowing the pad to be freely pulled from the liner area above the cavity

AI summary
An external defibrillator can include a tray and a plurality of electrode pads located within the tray. At least one of the plurality of electrode pads can include an electrode contact structure that can be applied to a patient, a wire electrically coupling the electrode contact structure to the external defibrillator, and a release liner adhered to the electrode contact structure of the electrode pad. A portion of the release liner can be affixed to a portion of the tray such that, when an end of the electrode pad is pulled, the electrode pad is removed from the release liner, the electrode pad is removed from the tray, and the release liner remains affixed to the tray.
