Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a traditional electroretinograph is used, then measurement precision is improved, but device complexity and cost increase
Solution Approach 1:
The patent extracts the essential measurement function from the complex traditional electroretinograph system. By using a portable display device with integrated electrodes and a simple connector, the core electrophysiological measurement capability is separated from the bulky, expensive, and complex traditional equipment, achieving accurate measurements with a simplified system.
Solution Approach 2:
The portable display device serves multiple functions: it acts as both a visual stimulation source and a measurement device through integrated electrodes. The closure lips structure simultaneously provides light isolation and electrode positioning, creating a multi-functional system that replaces multiple separate traditional devices.
2Measurement precision
If a traditional electroretinograph is used, then measurement precision is improved, but ease of operation deteriorates
Solution Approach 1:
The patent combines the stimulation display, light isolation, and measurement functions into a single integrated portable device. The closure lips structure integrates multiple functions including light blocking and electrode positioning, eliminating the need for separate equipment and complex setup procedures required by traditional systems.
Solution Approach 2:
The device enables self-contained operation where the portable display unit with integrated electrodes and closure lips can perform complete electroretinogram examinations independently. The system requires minimal external equipment and can be operated without the specialized infrastructure needed for traditional electroretinographs.
3Measurement precision
If traditional examination settings are used, then measurement precision is improved, but productivity deteriorates
Solution Approach 1:
The patent employs a portable, lightweight device that can be easily deployed and relocated, replacing the need for permanent specialized examination rooms and infrastructure. The simplified device requires minimal setup and can be used in various locations, enabling more frequent examinations without requiring dedicated hospital facilities.
Solution Approach 2:
The device transitions from static, fixed-location traditional electroretinographs to a dynamic, portable system that can be moved and deployed flexibly. This dynamic capability allows examinations to be performed in various settings and increases the frequency at which examinations can be conducted without being constrained by fixed facility availability.
