Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple electronic components are integrated into a single contact lens to create a versatile smart contact lens system, then the functionality and versatility of the lens is improved, but the space available on the contact lens is exceeded and power consumption increases significantly
Solution Approach 1:
The system divides the smart contact lens functionality into two separate contact lenses, each containing a subset of electronic components. The first contact lens contains certain sensors and controllers, while the second contact lens contains different sensors and controllers. This segmentation allows each lens to have fewer components, reducing space constraints while maintaining overall system versatility through the combined functionality of both lenses.
Solution Approach 2:
The invention transitions from a single-lens architecture to a multi-lens architecture, adding the dimension of spatial distribution across multiple lenses. By distributing components across two contact lenses rather than concentrating them in one, the system overcomes the area limitations of a single lens while preserving functional capabilities.
2Adaptability or versatility
If multiple electronic components are integrated into a single contact lens to enable multifunctional operations, then the versatility of the lens is improved, but the power consumption escalates significantly
Solution Approach 1:
The system segments the power-consuming electronic components across two contact lenses, with each lens containing only the specific sensors and controllers needed for its designated functions. This segmentation reduces the total power consumption compared to having all components in a single lens, as each lens operates with a smaller subset of components while the combined system maintains multifunctional capability.
3Device complexity
If a single contact lens is designed with all necessary components for versatile functionality, then the system complexity is reduced, but the difficulty of manufacturing and fitting increases
Solution Approach 1:
The invention segments the complex system into two simpler contact lens units, each with a manageable set of components. This segmentation makes manufacturing easier for each individual lens while the overall system complexity is managed through standardized communication protocols and master-slave coordination between the two lenses.
Solution Approach 2:
Both contact lenses are designed with universal communication capabilities and can function in either master or slave roles. This universality simplifies manufacturing by using common components and protocols across both lenses, while the master-slave coordination enables versatile functionality without requiring each lens to be uniquely complex.
Data Source
AI summary
A smart contact lens system and corresponding method for system control and exchanging data and commands between the two components has been disclosed. The system establishes a Master-Slave operational relationship between constituent components. Master-Slave relationship can exist between the two contact lenses, where one lens is a master while the other is a slave or between an external device which may serve as the master component and the contact lenses which may serve as the slave component. The system also comprises a smart contact lens substrate with an embedded communication module and a power supply module. The method to facilitate system control as well as data and commands exchange includes detecting the active system components, dynamically bonding and pairing the detected active components, dynamically or statically categorizing one of the component as master and the other one as slave and exchanging information and commands between the components.
