Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional electrode placement methods are used, then electrode placement can be performed, but the process is cumbersome and requires multiple hands
Solution Approach 1:
The patent combines the electrode preparation (peeling adhesive stickers) and placement functions into a single integrated gun device. The cartridge holds multiple electrodes with adhesive stickers that are automatically applied to the patient's skin when the gun is triggered, eliminating the need for separate manual preparation and placement steps that previously required multiple hands.
Solution Approach 2:
The electrodes are pre-prepared in the cartridge with adhesive stickers already attached to the wing-like casings. This preliminary preparation allows the electrodes to be ready for immediate placement without requiring manual peeling and preparation during the procedure, enabling single-handed operation.
2Ease of operation
If wing-like casings with adhesive stickers are used, then electrode placement is simplified, but the risk of needle stick injury during removal increases
Solution Approach 1:
The patent converts the potential harm of exposed sharp leads during removal into a benefit by designing the wing-like casings to automatically cover the leads when folded inward. The same wing-like structure that enables easy placement with adhesive stickers now provides safety by enclosing the sharp leads during removal, transforming the potential hazard into a protective feature.
3Productivity
If manual electrode preparation and placement is performed, then electrodes can be placed on the patient, but the process is time-consuming and inefficient
Solution Approach 1:
Multiple electrodes are pre-loaded into the cartridge with adhesive stickers already prepared. This preliminary action eliminates the time-consuming manual peeling and preparation steps during the procedure, allowing rapid sequential placement by simply triggering the gun multiple times.
Solution Approach 2:
The patent segments the electrode placement process into discrete, rapid units by providing multiple pre-prepared electrodes in the cartridge. Each electrode can be quickly dispensed and placed independently through simple trigger activation, significantly increasing placement efficiency compared to preparing and placing electrodes one by one manually.

Function Achieved in This Case
Enables efficient and single-handed placement and preparation of neuromonitoring electrodes, simplifying the process and reducing the risk of electrode movement or needle stick injuries.
Implementation Method 1
The adhesive stickers then form a strong bond to the skin to prevent electrode movement.

AI summary
Exemplary pre-operative electrode-dispensing neuromonitoring gun systems and methods involve the administration of a neuromonitoring electrode to a patient. A system can include a dispensing device and a cartridge. The dispensing device can have a case, a trigger, and a pusher. The cartridge can have a plurality of electrodes. In some cases, an electrode can include two subdermal leads, a posterior connection port or plug, and a casing to house the connection port before placement and to cover the leads upon removal.
