Solution Overview

Problem

Existing endoscopes require very long rods for observing high and distant objects, leading to poor storage and handling due to increased length.

Innovation Solution

A telescopic rod endoscope design with a telescopic pipe system, including a shaping pipe, guide pipe, and connecting line, allowing for extension and contraction, enabling observation of distant targets with directional adjustments and compact storage when not in use.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Length of moving object

If the length of the long rod is increased to observe high and distant objects, then the observation capability is improved, but the storage convenience deteriorates

Engineering Contradiction:

Improverod lengthVSAvoidstorage convenience

Core Design Contradiction:

Length of moving objectVSEase of operation

Solution Approach 1:

The rod structure is transformed from a fixed length to a dynamically adjustable telescopic structure. The telescopic pipe can be extended to a first length for observing distant objects and contracted to a second length for convenient storage, allowing the system to adapt its length based on operational needs.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The telescopic pipe employs a nested structure where multiple pipe sections are inserted within each other. When contracted, the inner pipes are retracted into outer pipes, creating a compact form factor that solves the storage convenience problem while maintaining the capability for extension when needed.

Inventive Principle:

Principle #7Nested doll (Nesting)

2Length of moving object

If the telescopic pipe is extended to observe distant targets, then the observation distance is improved, but the connecting line is subjected to friction damage

Engineering Contradiction:

Improveobservation distanceVSAvoidconnecting line durability

Core Design Contradiction:

Length of moving objectVSReliability

Solution Approach 1:

A guide pipe is introduced as an intermediary component to manage the connecting line during telescopic pipe extension. The guide pipe provides a protected pathway for the connecting line, preventing direct contact with friction-prone surfaces and reducing wear on the line.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The guide pipe is designed with a silica gel gasket that provides protective cushioning for the connecting line before friction damage can occur. This preventive measure ensures the connecting line is shielded from abrasion during the extension and contraction operations.

Inventive Principle:

Principle #11Beforehand cushioning (Prior cushioning)

AI summary

Disclosed is a telescopic rod endoscope, including a shaping pipe, wherein one end of the shaping pipe is fixedly connected to one end of a telescopic pipe; a camera is mounted at the other end of the shaping pipe; the other end of the telescopic pipe is fixedly connected to a guide pipe; a connecting line is sleeved between inner cavities of the guide pipe and the telescopic pipe; and one end of the connecting line penetrates through the shaping pipe and is electrically connected to the camera, and the other end of the connecting line penetrates through the guide pipe and is connected to an external interface. Through extension and contraction of the telescopic pipe, the telescopic pipe facilitates observation of high and distant targets when being extended, and the shaping pipe is convenient for the camera to make small directional changes, thereby facilitating observation.
