Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a desktop microscope is used to capture optical interference patterns, then measurement precision can be maintained, but device complexity and portability are compromised due to limited angle adjustment capability
Solution Approach 1:
The patent introduces a dynamic angle adjustment mechanism that allows the optical path assembly to be rotated and tilted in real-time during detection. This enables the system to adapt to different incident angles required for capturing optical interference patterns, transforming the static desktop microscope setup into a dynamic, adjustable configuration that maintains measurement precision while improving operational flexibility
Solution Approach 2:
The patent adds multi-dimensional angle adjustment capabilities (azimuth and elevation angles) to the detection system. By introducing these additional rotational degrees of freedom, the system can capture optical interference patterns from multiple angles, effectively solving the limitation of fixed-angle desktop microscopes while maintaining measurement accuracy
2Measurement precision
If traditional optical sensing systems are used, then measurement accuracy is maintained, but portability and ease of use are reduced due to complex adjustment requirements
Solution Approach 1:
The patent integrates multiple functions into a single portable device: the detection module combines light source, optical path assembly with multi-angle adjustment, and imaging sensor; the device can perform both angle adjustment and optical interference pattern capture in one integrated system, eliminating the need for separate desktop microscope equipment and improving portability while maintaining measurement accuracy
Solution Approach 2:
The patent implements dynamic angle adjustment mechanisms that allow real-time modification of the optical path during detection. This dynamic capability enables the portable device to adapt to different measurement conditions and patient anatomies, maintaining measurement precision while significantly improving portability and ease of use compared to fixed desktop systems

AI summary
Provided is an intraocular pressure measuring device, consisting of an intraocular pressure sensor with a Fabry-Perot cavity, a shooting element consisting of a lens, and a shooting module consisting of a housing with a shooting hole, an optical path assembly in the housing, and a light source outside the housing. The light is transmitted to the Fabry-Perot cavity after passing through the optical path assembly, and forms an interference pattern. The shooting hole cooperates with the lens to obtain the interference pattern through the shooting element. With the shooting module adapted to existing shooting elements, the device can detect the intraocular pressure with an existing shooting element. The positions of the shooting module and the shooting element are adjustable according to the position of the Fabry-Perot cavity, so the incident light beam fulfills the normal incidence requirement, making it easier to adjust the angle during detection.
