Solution Overview

Problem

Existing endoscope apparatuses face challenges in efficiently and intuitively controlling the bending of their distal ends, particularly in medical and industrial applications, where precise directional control is necessary but often hindered by cumbersome operation mechanisms.

Innovation Solution

An introducing apparatus with an electric bending drive mechanism, a rotary knob, a dial for orthogonal bending control, a transmission mechanism, and a detecting section, integrated into an operating section with a rectangular housing, allowing for single-handed operation with improved ergonomics and reduced operator burden.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a manual knob is used for bending operation, then the operator can directly control the bending section, but the operation becomes cumbersome and requires two hands

Engineering Contradiction:
Improvebending control operationVSAvoidoperation mechanism
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent replaces the manual mechanical knob with an electric bending drive mechanism that uses a motor to drive the bending section. The dial with rotary mechanism and transmission mechanism converts rotational input into precise bending control, eliminating the need for direct manual manipulation of complex mechanical knobs and enabling single-handed operation.

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

2Adaptability or versatility

If an RL dial is added for orthogonal bending control, then both up/down and right/left bending directions can be controlled, but the operating section becomes more complex

Engineering Contradiction:
Improvebending direction controlVSAvoidoperating section structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent combines the UD knob and RL dial into a single integrated operating section housing. The rotary mechanism and transmission mechanism are merged into a compact arrangement where the dial rotates on a rotary shaft, and the transmission mechanism efficiently couples the rotation to the electric bending drive mechanism, achieving dual-directional control without excessive structural complexity.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent introduces a second rotational dimension through the dial that operates orthogonally to the UD knob. The dial's rotation axis is perpendicular to the UD knob's axis, enabling control in both up/down and right/left bending directions by adding a dimensional aspect to the operation interface.

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

3Ease of operation

If the transmission mechanism transmits rotation along an axis deviating from the rotary shaft axis, then the dial can be positioned for better ergonomics, but the transmission mechanism becomes more complex

Engineering Contradiction:
Improvedial positioningVSAvoidtransmission mechanism
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent employs a transmission mechanism that acts as an intermediary between the dial's rotary shaft and the electric bending drive mechanism. This transmission mechanism, which may include gears or other transmission elements, efficiently transfers and transforms the rotational motion from the dial to the drive mechanism, enabling ergonomic dial positioning while maintaining reliable force transmission.

Inventive Principle:
Principle #24Intermediary (Mediator)
