Wireless CFS System with Disposable Pads
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current cutaneous field stimulation (CFS) systems are not well-suited for treating pain or itch distributed over multiple areas, as they require repeated use on each zone and lack convenience and ease of use, especially in combining Aβ and Aδ/C fiber stimulation effectively.
Innovation Solution
A CFS system featuring self-adhesive, disposable pads with a sealed, cleanable battery/controller pod and wireless capability, allowing connection to a smartphone for easy upgradability and user-friendly control, enabling simultaneous stimulation of multiple sites with adjustable parameters and scalability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional CFS systems are used to treat pain or itch distributed over multiple areas, then treatment effectiveness is maintained, but convenience and ease of use deteriorate due to requiring repeated use on each zone
Solution Approach 1:
The system divides the treatment area into multiple independently controllable channels, each capable of stimulating different zones simultaneously. The controller can independently adjust parameters for each channel, allowing parallel treatment of multiple pain or itch zones without requiring sequential manual intervention.
Solution Approach 2:
The system combines multiple stimulation channels and control functions into a single integrated device that can simultaneously address multiple body zones. By merging the capabilities of multiple traditional CFS units into one system with centralized control, the device eliminates the need for repeated separate treatments while maintaining therapeutic effectiveness.
2Reliability
If multiple needle-like electrodes are used to stimulate different nerve fibers, then treatment effectiveness is improved, but device complexity increases
Solution Approach 1:
The system employs a universal controller that can manage multiple electrode channels through a single interface. This multi-functional controller handles stimulation, parameter adjustment, and monitoring across all channels, reducing the need for separate control devices for each electrode type while maintaining the ability to stimulate different nerve fibers effectively.
Solution Approach 2:
The system introduces a centralized controller as an intermediary between the user and multiple electrode channels. This mediator simplifies the interface by providing unified control over all stimulation parameters, automatically managing the complexity of coordinating multiple electrodes while preserving treatment effectiveness.
3Adaptability or versatility
If fixed treatment parameters are used for CFS, then ease of operation is improved, but adaptability to different pain or itch conditions deteriorates
Solution Approach 1:
The system provides dynamically adjustable treatment parameters that can be modified in real-time based on patient response and specific condition requirements. Each channel allows independent adjustment of stimulation intensity, frequency, and duration, enabling the system to adapt to varying pain or itch conditions while maintaining user-friendly control through automated protocols and preset programs.

AI summary
A CFS system includes self-adhesive, disposable pads. Each pad is combined with a sealed, cleanable battery/controller pod and then placed on the body where needed. The battery/controller pod preferably has wireless capability, such as Bluetooth® capability. The patient can download an application to a smartphone or similar mobile device to control the pods.
