An OCT device design that utilizes a single OCT main unit with an optical distributor to direct laser light to multiple probes via probe-connection optical fibers, allowing for the use of multiple probes with a single main unit, reducing the need for multiple main units and minimizing space and cost.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple OCT main units are installed to accommodate multiple probes, then the number of probes that can be used increases, but the space occupied and cost increase
Solution Approach 1:
Multiple OCT main units are merged into a single integrated unit by combining their light sources and optical components. The patent describes a configuration where light sources from multiple units are consolidated, and optical distributors are integrated to route light to multiple probes, thereby reducing the total space occupied while maintaining the capability to support multiple probes simultaneously
Solution Approach 2:
The OCT main unit is designed with universal functionality to support multiple probes through integrated optical distributors that can dynamically allocate light paths. The system provides multi-functionality by enabling a single unit to perform the roles previously requiring multiple separate units, allowing flexible configuration for different numbers of probes without requiring additional main units
2Adaptability or versatility
If multiple OCT main units are installed to accommodate multiple probes, then the number of probes that can be used increases, but the cost increases
Solution Approach 1:
The patent consolidates expensive components such as light sources, optical distributors, and control systems into a single shared infrastructure. By merging these components, the system eliminates redundant purchases and reduces overall manufacturing and acquisition costs while maintaining the ability to support multiple probes through the integrated optical routing architecture
3Area of stationary object
If a single OCT main unit is used with multiple probes, then space and cost are reduced, but the complexity of light distribution increases
Solution Approach 1:
Optical distributors are introduced as intermediary components that simplify the light distribution architecture. These distributors act as mediators between the single light source and multiple probes, providing organized and manageable light routing paths. The patent describes how these intermediary optical components streamline the distribution process while reducing the overall system complexity compared to having multiple independent main units

AI summary
An optical coherence tomography imaging device (OCT device) splits laser light emitted from a light source into measurement light for irradiating an object and reference light for irradiating a reference mirror, then analyze the interference light formed by combining scattered measurement light reflected back from the object and reflected reference light reflected from the reference mirror in order to generate tomographic images. An OCT device includes a probe, which is used for irradiating the object with measurement light and collecting scattered measurement light that is reflected back from the object, and an OCT main unit, which includes a light source for emitting measurement light. The probe is arranged on an odonto-therapy unit equipped with an instrument hanger, and includes a probe-connection optical fiber for transmitting measurement light and scattered measurement light. The probe-connection optical fiber is detachably connected to the OCT main unit.
