Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If existing neuromodulation devices use predetermined and preconfigured electrical stimulation protocols, then the device complexity is reduced and ease of manufacture is improved, but the adaptability and user control over stimulation waveforms deteriorates
Solution Approach 1:
The patent segments the electrical stimulation protocol into multiple adjustable parameters including waveform type, frequency, amplitude, pulse width, and duty cycle. This segmentation allows users to independently control each parameter through a user interface, transforming a fixed protocol system into an adaptable one while maintaining manufacturing simplicity through modular design
Solution Approach 2:
The system transitions from static preconfigured protocols to dynamic user-controllable parameters. The device incorporates real-time adjustment capabilities where users can modify stimulation waveforms during operation, and the system can adapt based on user feedback and physiological responses, thereby enhancing versatility without compromising ease of manufacture
2Device complexity
If existing neuromodulation devices use predetermined electrical stimulation protocols, then the device complexity is reduced, but the ease of operation and user autonomy deteriorates
Solution Approach 1:
The patent implements self-service functionality by enabling users to independently select, adjust, and control electrical stimulation parameters without requiring professional intervention. The user interface allows intuitive control of waveform parameters, and the system includes built-in guidance and feedback mechanisms that simplify operation while maintaining appropriate complexity management
Solution Approach 2:
The system provides standardized parameter adjustment interfaces that allow users to modify stimulation characteristics through simple controls. By presenting parameters in user-friendly formats with preset options and real-time feedback, the system enhances ease of operation while managing device complexity through structured parameter management
3Device complexity
If existing neuromodulation devices lack user interface for waveform control, then the device complexity is reduced, but the ease of operation and user control deteriorates
Solution Approach 1:
The patent introduces a user interface as an intermediary between the user and the electrical stimulation system. This interface layer includes display elements, control buttons, sliders, and feedback mechanisms that simplify the interaction with complex waveform parameters, thereby enhancing ease of operation without significantly increasing the core device complexity
Solution Approach 2:
The user interface is designed to serve multiple functions including waveform selection, parameter adjustment, real-time monitoring, and feedback collection. By consolidating these functions into a single integrated interface, the system improves ease of operation while managing device complexity through multi-functional design rather than separate controls for each function
