Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Length of moving object

If the endoscope shaft diameter is decreased to achieve miniaturization, then the endoscope can access smaller anatomical spaces, but image resolution deteriorates due to fewer optical fibers or smaller CMOS sensor

Engineering Contradiction:
Improveendoscope shaft diameterVSAvoidimage resolution
Core Design Contradiction:
Length of moving objectVSMeasurement precision

Solution Approach 1:

The patent combines multiple functions (illumination, imaging, articulation control) into a single integrated endoscope shaft. By merging the LED light source with the CMOS sensor in a compact distal assembly, and integrating articulation wires within the same shaft structure, the design achieves miniaturization without sacrificing resolution. This consolidation allows adequate light delivery to the smaller sensor while maintaining image quality.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent implements a dynamically articulating distal endoscope shaft that can bend and articulate manually. This dynamic capability allows the shaft to navigate complex anatomical pathways while maintaining a small overall diameter. The articulation wires enable the distal portion to be positioned precisely without requiring a larger rigid shaft, thus preserving both access capability and image resolution.

Inventive Principle:
Principle #15Dynamics

2Illumination intensity

If an LED is placed adjacent to a CMOS sensor at the tip of the endoscope to improve light output, then image quality improves, but the shaft/tip diameter increases

Engineering Contradiction:
Improvelight outputVSAvoidshaft tip diameter
Core Design Contradiction:
Illumination intensityVSLength of moving object

Solution Approach 1:

The patent nests the LED light source within or adjacent to the CMOS sensor assembly in a compact distal configuration. The illumination optics are integrated into the same housing structure as the sensor, with light delivered through small-diameter optical pathways. This nested arrangement provides adequate illumination for the CMOS sensor while maintaining a small overall tip diameter that fits within standard endoscope shaft constraints.

Inventive Principle:
Principle #7Nested doll (Nesting)

3Adaptability or versatility

If multiple device consoles are used to operate different surgical instruments, then each instrument can be controlled independently, but operational complexity and cost increase

Engineering Contradiction:
Improveinstrument control capabilityVSAvoidnumber of device consoles
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent designs the endoscope with universal connectivity features including standardized attachment mechanisms for various surgical instruments (graspers, scissors, energy devices). The endoscope housing includes multiple attachment sites and compatible coupling mechanisms that allow a single endoscope system to support multiple different instrument types. This multi-functional capability eliminates the need for separate dedicated consoles for each instrument, reducing overall system complexity while maintaining versatility.

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