Solution Overview

Problem

Current medical imaging devices, such as laparoscopes and endoscopes, often require multiple cameras to capture comprehensive views of internal body regions, but they lack the flexibility to adjust their field of view without changing the orientation or position of the device, which can limit the precision and effectiveness of medical procedures.

Innovation Solution

A medical imaging device with a handle, an elongated rigid shaft, and an extendible sleeve that allows the optical gear to change its field of view by sliding along the shaft, enabling adjustable positioning of cameras within the body without altering the device's orientation, using a control unit to manage the extension and collapse of the sleeve and provide power and data to multiple optical gears.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple cameras are used to capture comprehensive views of internal body regions, then the field of view coverage is improved, but the device complexity and difficulty of maneuvering increase

Engineering Contradiction:
Improvefield of view coverageVSAvoiddevice complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The extendible sleeve is nested within the elongated rigid shaft, creating a telescopic structure that allows the optical gear to extend and retract along the shaft's longitudinal axis. This nesting arrangement enables multiple cameras to be housed within a compact configuration while maintaining the capability to extend the field of view when needed, thus improving coverage without permanently increasing device complexity.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The optical gear is designed with dynamic extendibility, allowing it to change its position along the longitudinal axis of the shaft. This dynamic adjustment capability enables the system to adapt the field of view coverage based on procedural needs, while the optical gear itself remains a single integrated unit that can be maneuvered as one piece, reducing the complexity associated with multiple separate camera systems.

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If the camera position is fixed on the rigid shaft, then the device structure is simple, but the ability to adjust field of view without changing device orientation is limited

Engineering Contradiction:
Improvefield of view adjustabilityVSAvoidease of maneuvering
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The optical gear is designed to slide along the longitudinal axis of the rigid shaft, enabling dynamic adjustment of the field of view. This sliding mechanism allows the camera position to be changed without requiring the entire device to be repositioned or reoriented, thereby improving field of view adaptability while maintaining ease of operation through a simple linear movement along the shaft.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The device is segmented into the rigid shaft and the extendible optical gear, allowing independent movement of the optical component along the shaft. This segmentation enables the field of view to be adjusted by moving only the optical gear rather than the entire device, improving adaptability while keeping the maneuvering process straightforward and controlled.

Inventive Principle:
Principle #1Segmentation

3Adaptability or versatility

If the extendible sleeve is used to slide the optical gear along the shaft, then the field of view flexibility is improved, but the device structure becomes more complex

Engineering Contradiction:
Improvefield of view flexibilityVSAvoidstructural complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The extendible sleeve is nested within the rigid shaft, creating a telescopic structure that adds field of view flexibility through a relatively simple geometric arrangement. This nested configuration allows the optical gear to extend and retract along the shaft without requiring complex external mechanisms, thus improving adaptability while minimizing the increase in structural complexity.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The extendible sleeve serves multiple functions: it houses the optical gear, provides a sliding mechanism for field of view adjustment, and maintains structural integrity during extension and retraction. This multi-functionality reduces the need for additional separate components, thereby improving field of view flexibility without proportionally increasing overall device complexity.

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