Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If bulky stimulators with preloaded waveforms are used, then biomimetic stimulation patterns can be achieved, but the device size and complexity increase, making implantation impractical
Solution Approach 1:
The patent extracts the waveform storage and processing functions from a bulky external system and implements them in a compact implantable form factor using modern integrated circuits and memory technologies, enabling biomimetic stimulation without requiring large external equipment
Solution Approach 2:
The patent changes the technical parameters of the stimulator by using advanced semiconductor fabrication and integrated circuit design to reduce device size while maintaining or enhancing computational capabilities for generating biomimetic waveforms
2Device complexity
If traditional programmable neural stimulators are used, then device size can be reduced for implantation, but the ability to mimic biological waveforms in real-time is lost
Solution Approach 1:
The patent pre-loads waveform templates and parameter sets into the implantable device's memory before implantation, enabling the device to rapidly generate and adapt biomimetic waveforms in real-time without requiring complex external control systems
Solution Approach 2:
The patent implements feedback mechanisms that allow the implantable stimulator to monitor physiological responses and dynamically adjust stimulation parameters to maintain accurate biomimetic waveforms, enabling real-time adaptation within the constraints of a compact device
3Reliability
If non-periodic, non-uniform stimulation is implemented, then therapeutic effectiveness is improved, but the complexity of controlling stimulation parameters increases
Solution Approach 1:
The patent implements dynamic control of stimulation parameters by using programmable pulse generators that can vary pulse width, amplitude, and timing based on pre-loaded protocols or real-time feedback, enabling non-periodic stimulation patterns without requiring overly complex control mechanisms
Data Source
AI summary
A neural stimulator system which generates stimulation from an implantable stimulator circuit which generates stimulation outputs which mimic biological signals. The user/operator can select stimulation generated from recorded waveforms, or by selecting the characteristics for generating stimulation based on randomized inter-pulse-intervals (IPI). A control unit controls the operation of the implantable stimulator circuit, and receives sets of stimulation parameters based on user input from a user input device executing application specific programming.
