Brain Stimulation Device Usage Authorization via Time Token
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing brain stimulating devices lack a secure method for configuring usage authorization, particularly for non-invasive devices that need to be shared among multiple users, necessitating a solution to ensure safe operation based on user identification and usage limits.
Innovation Solution
A method and system that utilize a time token for configuring usage authorization, where a personal communication device transmits user identification to a server, receives a time token for the brain stimulating device, and deactivates it after the designated usage duration, ensuring safe and customized operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If non-invasive brain stimulation device is made shareable among multiple users, then ease of operation and accessibility are improved, but safety and usage control become more complex
Solution Approach 1:
The patent segments the authorization mechanism by introducing time tokens that are individually allocated to each user. Each user receives a unique time token with specific usage parameters (duration, frequency limits, time windows), allowing the device to be shared while maintaining individualized safety controls. This segmentation enables multiple users to safely access the device without compromising reliability.
Solution Approach 2:
The patent introduces a server as an intermediary between users and the brain stimulation device. The server manages time token generation, validation, and revocation, acting as a mediator that enforces safety rules and usage limits. This intermediary layer ensures that even when the device is physically accessible to multiple users, safety and usage control are maintained through centralized authorization management.
2Reliability
If usage authorization is configured for each user, then safety and reliability are improved, but device complexity increases
Solution Approach 1:
The patent extracts the complex authorization management functionality from the brain stimulation device itself and places it in an external server. The device only needs to validate time tokens received from the server, significantly reducing its complexity. The server handles the heavy lifting of managing user profiles, usage limits, and authorization logic, allowing the device to remain simple while maintaining high reliability through external authorization management.
Solution Approach 2:
The patent uses time tokens that encode usage parameters (duration, frequency, time windows) in a standardized format. By changing the representation of authorization data from complex database queries to structured token parameters, the system achieves both safety and reduced complexity. The device simply needs to parse and validate these parameters rather than implementing full authorization logic.
3Reliability
If time token validation is implemented, then usage control and safety are improved, but processing time and operational steps increase
Solution Approach 1:
The patent implements preliminary action by having users obtain time tokens from the server before using the device. The server pre-validates user eligibility, usage limits, and time windows in advance, embedding all authorization logic in the token itself. When the user presents the token at the device, validation is immediate and straightforward, minimizing processing time while maintaining comprehensive usage control.

AI summary
Disclosed is a method for setting authority for use of a brain stimulation device and a device implementing the same, and the method for setting authority for use of a brain stimulation device according to the present disclosure comprises the steps in which: a communication unit of a personal communication device receives, from a server device, a time token for which the authority for use of the brain stimulation device is set; the communication unit transmits the time token to the brain stimulation device or the server device; and after a time corresponding to the usage time of the brain stimulation device stored in the time token has elapsed, the communication unit receives, from the brain stimulation device or the server device, a message to delete the time token or to change the value of a specific field of the time token.
