Rigid Endoscope Key Relocation to Reduce False Triggering

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing imaging apparatuses for rigid endoscopes suffer from false triggering issues due to the key being arranged at the handle component, which is prone to accidental activation during user operation.

Innovation Solution

The key component is relocated to the first connection part, away from the handle component, and is connected via a signal transmission system that includes independent conductors or wireless elements to maintain stability and prevent false triggering.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the key component is arranged at the handle component, then the operation is convenient, but false triggering occurs during user operation

Engineering Contradiction:

Improvekey accessibilityVSAvoidfalse triggering

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The key component is extracted from the handle component and relocated to the connection component. This separation removes the key from the area where users frequently operate the handle, thereby eliminating accidental triggering while preserving intentional key activation through the connection interface

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The connection component serves as an intermediary between the user's intentional activation and the image processing component. By placing the key on the connection component rather than the handle, the system introduces a mediating interface that reduces accidental activation while maintaining controlled access to the imaging function

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If the key component is relocated to the connection component, then false triggering is reduced, but the signal transmission complexity increases

Engineering Contradiction:

Improvefalse triggering reductionVSAvoidsignal transmission structure

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The connection component is designed to serve multiple functions: it provides mechanical connection between the endoscope and imaging apparatus, enables signal transmission from the key component, and facilitates optical signal passage. This multi-functionality consolidates what would otherwise be separate components, reducing overall system complexity

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

Provided are an imaging apparatus for a rigid endoscope and an endoscope system. The imaging apparatus includes a connection component, a key component, a handle component, and an optical component. The connection component includes a first connection part and a second connection part; the first connection part includes a first section and a second section. One end of the second section is connected with the first section, the other end of the second section is connected with the second connection part. The key component is arranged at the first connection part; the handle component is capable of being driven by an external force to move relative to the key component. In this disclosure, the key component is arranged at the first connection part, which is usually far away from a portion which is operated by a user, which improves a false triggering when the user operates the handle component.
