Ophthalmic Apparatus Attachment State Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional ophthalmic apparatuses fail to prevent imaging in inappropriate modes when attachment units are not correctly matched with designated imaging modes, leading to suboptimal or incorrect imaging of a subject's eye.
Innovation Solution
An ophthalmic apparatus with an operation unit for designating imaging modes, an attachment state determination unit to assess the presence and type of attachment units, and a controller to prohibit imaging if the correspondence between the designated mode and attachment state or type is inappropriate, ensuring appropriate imaging settings are maintained.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the ophthalmic apparatus allows imaging in any designated mode regardless of attachment state, then the ease of operation is improved, but the reliability of imaging quality deteriorates
Solution Approach 1:
The apparatus implements feedback by detecting the attachment state through sensors and comparing it with the designated imaging mode. The system provides real-time feedback to the user when a mismatch is detected, preventing inappropriate imaging operations and ensuring that only compatible mode-attachment combinations are executed.
2Reliability
If the ophthalmic apparatus adds correspondence determination functions, then the reliability of imaging is improved, but the device complexity increases
Solution Approach 1:
The control unit serves multiple functions: it controls the imaging operation, detects the attachment state through integrated sensors, determines correspondence between mode and attachment, and provides user notifications. By consolidating these functions into a single control unit, the patent avoids adding separate complex subsystems while achieving reliable correspondence verification.
3Manufacturing precision
If the ophthalmic apparatus prohibits imaging when correspondence is inappropriate, then the imaging quality is improved, but the productivity decreases
Solution Approach 1:
The apparatus performs preliminary verification of attachment state and mode correspondence before the imaging operation commences. By detecting mismatches in advance and providing notification to the user, the system prevents wasted imaging operations while allowing quick correction by the user, thereby minimizing impact on overall productivity.

AI summary
An ophthalmic apparatus capable of selectively performing a first imaging mode in which imaging of a subject's eye is performed in a first state where an attachment unit is not attached, and a second imaging mode in which imaging of the subject's eye is performed in a second state where the attachment unit is attached. The ophthalmic apparatus includes: an operation unit; an attachment state determination unit to determine whether or not the attachment unit is attached; a correspondence determination unit to determine whether or not the correspondence between the imaging mode designated by a use of the operation unit and an attachment state of the attachment unit obtained by the attachment state determination unit is appropriate; and a controller to perform control for prohibiting imaging in at least the designated imaging mode when the correspondence determination unit has determined that the correspondence is not appropriate.
