Solution Overview

Problem

In medical procedures involving endoscopes, the indirect view through an endoscope is often replaced by a camera, but medical staff other than the operator struggle to intuitively determine the endoscope's orientation and viewing direction, relying on verbal cues or anatomical knowledge, which can be cumbersome and less efficient.

Innovation Solution

A system comprising a movable holding device for an image reproduction device that synchronizes its orientation with the image capturing device's orientation, using a controller to adjust the image display based on the viewing direction of the endoscope, allowing for intuitive alignment and improved visualization.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the image reproduction device is fixed in position, then the device structure is simple, but the medical staff cannot intuitively understand the endoscope's orientation and viewing direction

Engineering Contradiction:
Improveintuitive understanding of endoscope orientationVSAvoidholding device structure
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent applies the dynamics principle by making the image reproduction device movable rather than fixed. The holding device includes drive mechanisms that enable the screen to move and rotate dynamically, allowing it to follow the orientation changes of the endoscope. This dynamic capability enables medical staff to intuitively understand the endoscope's viewing direction by observing the screen's position and orientation in space.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent uses the image reproduction device as an intermediary between the endoscope and the medical staff. The holding device acts as a mediator that translates the endoscope's spatial orientation into corresponding screen position and orientation. This intermediary system bridges the gap between the operator's direct visual feedback and the indirect view on screen, making the endoscope's orientation intuitive for all participants.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Loss of information

If the image reproduction device follows the endoscope orientation dynamically, then the visualization becomes intuitive, but the device complexity increases

Engineering Contradiction:
Improveorientation information transmissionVSAvoidcontrol system
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The patent implements feedback by continuously monitoring the endoscope's orientation (through sensors or controller signals) and using this information to automatically adjust the image reproduction device's position and orientation. The controller receives signals representing the endoscope's viewing direction and generates control signals to move the screen accordingly, creating a closed-loop system that maintains accurate orientation correspondence without requiring complex manual coordination.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The patent replaces complex mechanical coupling between the endoscope and screen with a control-based system. Instead of direct mechanical linkage, the system uses sensors, controllers, and drive devices to achieve orientation correspondence. This substitution reduces mechanical complexity while maintaining the functional relationship between endoscope orientation and screen display orientation.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Adaptability or versatility

If multiple medical staff members need to observe the procedure, then teamwork is improved, but the operator loses direct visual feedback

Engineering Contradiction:
Improvemulti-user observation capabilityVSAvoidoperator's direct visual feedback
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent resolves this contradiction by adding a spatial dimension to the display system. The image reproduction device can be positioned and oriented in three-dimensional space, allowing it to face different directions and serve multiple observers while maintaining orientation correspondence with the endoscope. This spatial flexibility enables multiple medical staff members to observe the procedure simultaneously without compromising the operator's ability to understand the viewing direction through the screen's orientation.

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