Solution Overview

Problem

Current neuromodulation systems face challenges in ensuring secure and controlled data transfer, particularly due to data interference and bidirectional communication, which can lead to invalid commands and energy inefficiencies.

Innovation Solution

A system with a connection managing module that enables only unidirectional data transfer between devices, preventing data interference and allowing secure, controlled data transmission, while also reducing energy consumption through selective temporal connections and encryption.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If bidirectional communication is implemented between devices, then ease of operation is improved, but data interference and security risks increase

Engineering Contradiction:
Improveease of operationVSAvoiddata interference
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The communication system is segmented into unidirectional communication channels between devices. Each device can transmit data to others but cannot receive data back, eliminating bidirectional communication that causes data interference. This segmentation maintains operational ease while preventing reliability issues through one-way data flow architecture.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Instead of implementing traditional bidirectional communication where devices can both send and receive data, the system inverts the approach by allowing only unidirectional transmission. Data flows in one direction only, preventing the interference that occurs when multiple devices attempt simultaneous two-way communication.

Inventive Principle:
Principle #13The other way round (Inversion)

2Speed

If continuous connection between devices is maintained, then real-time data transfer is improved, but energy consumption increases

Engineering Contradiction:
Improvereal-time data transferVSAvoidenergy consumption
Core Design Contradiction:
SpeedVSUse of energy by moving object

Solution Approach 1:

The system uses periodic activation of communication connections rather than continuous connection. Devices establish unidirectional communication channels only when data transfer is needed, then disconnect or enter low-power mode. This periodic action maintains real-time data transfer capability when required while significantly reducing overall energy consumption compared to continuous connection.

Inventive Principle:
Principle #19Periodic action

3Reliability

If encryption is implemented for secure data transfer, then reliability is improved, but device complexity increases

Engineering Contradiction:
Improvesecure data transferVSAvoiddevice complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The encryption functionality is merged into the existing unidirectional communication framework rather than being implemented as a separate complex system. By combining security measures with the already-simplified unidirectional data transfer architecture, the system achieves secure data transfer while minimizing additional device complexity.

Inventive Principle:
Principle #5Merging (Combining)
