Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If flexible material is attached to the eyeball surface for direct detection, then detection accuracy is improved, but user comfort deteriorates and detection convenience worsens
Solution Approach 1:
The patent replaces the mechanical contact-based detection system (flexible material attached to eyeball) with an optical detection system. The light-emitting assembly projects light onto the eyeball, and the optical signal receiving assembly captures the reflected light, which is then converted to electrical signals for intraocular pressure measurement. This substitution eliminates the need for physical contact while maintaining detection accuracy.
Solution Approach 2:
The patent introduces light as an intermediary medium between the detection device and the eyeball. Instead of direct mechanical contact, the system uses light interaction (absorption and reflection) to obtain intraocular pressure information. The light serves as a non-contact mediator that carries information about the eyeball's internal pressure state.
2Reliability
If flexible material is attached to the eyeball surface, then detection reliability is improved, but discomfort and potential harm to the eyeball increases
Solution Approach 1:
The patent replaces the mechanical contact system with an optical system that does not require physical attachment to the eyeball. The light-emitting assembly and optical signal receiving assembly operate without touching the eyeball surface, thereby eliminating discomfort and potential harm while maintaining reliable detection through optical signal analysis.
Solution Approach 2:
The patent creates an optical copy or representation of the eyeball's light interaction characteristics. By analyzing the reflected light patterns and absorption characteristics, the system obtains information about intraocular pressure without physically interacting with the eyeball, thus avoiding harm while maintaining detection reliability.

Function Achieved in This Case
The device provides a convenient and discomfort-free method for detecting intraocular pressure by using a non-contact approach, ensuring accurate measurements through the comparison of detection signals with pre-measured standards.
Implementation Method 1
The light-emitting assembly is configured to emit a first ray to the eyeball. The first ray is partially absorbed by the eyeball to form a second ray.
Implementation Method 2
The second ray is reflected by the eyeball to form a third ray.
Implementation Method 3
The optical signal receiving assembly is configured to convert the received third ray into a detection signal.
