Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the imaging target is moved between apparatuses for sequential OCT and fluorescence observation, then both imaging methods can be performed, but positional deviation occurs leading to reduced comparison accuracy

Engineering Contradiction:
Improvecapability to perform both OCT and fluorescence observationVSAvoidpositional accuracy for comparison and evaluation
Core Design Contradiction:
Adaptability or versatilityVSMeasurement precision

Solution Approach 1:

The patent combines OCT and fluorescence observation capabilities into a single integrated imaging apparatus. The imaging target remains stationary while the system switches between different imaging modes using shared optical components (light source, objective lens, imaging chamber), thereby eliminating positional deviation while maintaining the ability to perform both imaging methods.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The imaging apparatus is designed with multi-functionality to perform both OCT and fluorescence observation using a single device. Key components such as the light source unit, objective lens, and imaging chamber are shared between the two imaging methods, allowing the system to adapt to different imaging requirements without moving the imaging target.

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

2Ease of manufacture

If separate apparatuses are used for OCT and fluorescence observation, then each method can be optimized independently, but the imaging target must be moved causing positional deviation

Engineering Contradiction:
Improveindependent optimization of each imaging methodVSAvoidpositional accuracy for comparison and evaluation
Core Design Contradiction:
Ease of manufactureVSMeasurement precision

Solution Approach 1:

The patent merges separate OCT and fluorescence observation systems into a single integrated apparatus. By sharing common components (imaging chamber, objective lens, light source) while maintaining separate detection paths, the system achieves both independent optimization of imaging methods and elimination of positional deviation through the stationary imaging target.

Inventive Principle:
Principle #5Merging (Combining)

3Adaptability or versatility

If the imaging target is moved between apparatuses, then different imaging methods can be applied, but time is lost during relocation and positioning

Engineering Contradiction:
Improveability to switch between imaging methodsVSAvoidtime for moving and repositioning the imaging target
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The imaging target is pre-positioned within the shared imaging chamber of the integrated apparatus before imaging begins. This preliminary positioning eliminates the need for time-consuming relocation and repositioning when switching between OCT and fluorescence observation methods, as the target remains stationary throughout the imaging process.

Inventive Principle:
Principle #10Preliminary action
