Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current medical devices for managing cochlear and vestibular disorders lack comprehensive monitoring and diagnostic capabilities, particularly in cases of combined cochlear and vestibular implantations, leading to suboptimal therapeutic outcomes and potential device failures due to inadequate integration and monitoring of both systems.
Innovation Solution
A system comprising implanted cochlear and vestibular sensors and processors that collect and analyze biological state data from both systems, utilizing machine-learning frameworks to diagnose conditions and provide timely alerts for potential issues, while also incorporating external sensors like accelerometers and gyroscopes to monitor patient activity and balance functions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate cochlear and vestibular devices are used, then device complexity is reduced, but monitoring comprehensiveness and diagnostic capability deteriorate
Solution Approach 1:
The patent combines separate cochlear and vestibular monitoring functions into a single integrated system. The implantable device includes both cochlear electrodes for hearing monitoring and vestibular electrodes for balance monitoring, allowing comprehensive monitoring of both auditory and vestibular systems through one device rather than requiring separate devices.
Solution Approach 2:
The implantable device is designed with multi-functionality to perform both cochlear monitoring and vestibular monitoring. The device can selectively apply electrical stimuli to either cochlear or vestibular nerves and record responses from both systems, making it a universal monitoring platform that eliminates the need for multiple specialized devices.
2Measurement precision
If comprehensive monitoring of both cochlear and vestibular systems is implemented, then diagnostic capability is improved, but data processing complexity increases
Solution Approach 1:
The patent segments the monitoring process into distinct operational modes: cochlear monitoring mode and vestibular monitoring mode. The device can selectively activate one monitoring pathway at a time by controlling which electrodes are stimulated and which are used for recording, thereby simplifying data processing while maintaining comprehensive diagnostic capability.
Solution Approach 2:
The device employs dynamic configuration of electrode usage based on the monitoring mode. During cochlear monitoring, certain electrodes are configured for cochlear stimulation while others record cochlear responses; during vestibular monitoring, the same physical electrodes are reconfigured for vestibular functions. This dynamic reconfiguration allows comprehensive monitoring without permanently complex wiring or processing architecture.
3Measurement precision
If selective stimulation and monitoring is performed, then measurement precision is improved, but device operation complexity increases
Solution Approach 1:
The device incorporates feedback mechanisms that automatically adjust stimulation and recording parameters based on detected biological responses. The system monitors the electrical responses from cochlear or vestibular nerves and uses this feedback to optimize subsequent stimulation patterns, reducing the need for manual adjustment and simplifying operation while maintaining high measurement precision.
