Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a single beamsplitter module is used to split light beams, then the device complexity is reduced, but the functionality is limited and cannot provide simultaneous viewing and recording capabilities with informational overlays

Engineering Contradiction:
ImprovefunctionalityVSAvoiddevice complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system divides the beam splitting function into multiple specialized modules: a first beamsplitter module for separating viewing and recording beams, and a second beamsplitter module for creating informational overlays. Each module performs a specific function, allowing the system to achieve complex stereoscopic imaging and overlay capabilities while maintaining manageable complexity through functional decomposition

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The aligned beamsplitter modules are designed to work together in an integrated optical path that simultaneously supports multiple functions: stereoscopic viewing, recording, and informational overlays. The modules process different beam paths concurrently, enabling the system to perform multiple operations with a unified structure rather than requiring separate systems for each function

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Productivity

If multiple beamsplitter modules are aligned to provide simultaneous viewing and recording, then the functionality is enhanced, but the device complexity increases

Engineering Contradiction:
Improvesimultaneous viewing and recording capabilityVSAvoiddevice complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The system merges multiple beam paths and processing functions into a single integrated optical train. The first and second beamsplitter modules are aligned to work in sequence, combining stereoscopic viewing, recording, and overlay functions into one unified device. This consolidation allows simultaneous operations without requiring separate microscope systems for each function

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The aligned beamsplitter modules create distinct spatial dimensions for different beam paths within the optical system. By separating beams into different spatial trajectories (viewing path, recording path, overlay path) while maintaining temporal simultaneity, the system achieves multi-functionality without requiring sequential operations that would increase time complexity

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

AI summary

According to certain embodiments, a system includes beamsplitter sets, where each beamsplitter set comprises a first beamsplitter module and a second beamsplitter module aligned with the first beamsplitter module. The first beamsplitter module receives a first beam traveling along a first optical path. The first beamsplitter module splits the first beam into a first output beam transmitted along the first optical path and a first split beam transmitted to the second beamsplitter module along a reflected beam path. The second beamsplitter module receives the first split beam. The second beamsplitter module splits the first split beam into a second output beam transmitted substantially parallel to the reflected beam path and a second split beam transmitted substantially perpendicular to the reflected beam path.
