Solution Overview

Problem

Conventional detachable endoscopes are limited by fixed bending angles, requiring separate equipment for gastric and colonofiberscope surgeries, increasing maintenance and purchase costs due to the need for multiple devices.

Innovation Solution

A detachable endoscope with an adjustable bending angle, featuring a detachable unit with rack gears and pinion gears that allow for vertical and horizontal bending adjustments via simple rotational operations, enabling the same insertion part to perform both gastric and colonofiberscope surgeries.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a detachable endoscope uses a fixed bending angle design, then the structure is simple and reliable, but separate equipment is required for gastric and colonofiberscope surgeries, increasing maintenance and purchase costs

Engineering Contradiction:
Improvebending angle adaptabilityVSAvoidstructure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies the dynamics principle by replacing the fixed bending angle mechanism with an adjustable bending angle mechanism. The insertion part incorporates a bending mechanism that can dynamically change its bending angle according to surgical requirements, allowing the same endoscope to adapt between gastric surgery (larger bending angle) and colonofiberscope surgery (smaller bending angle) modes, thereby eliminating the need for separate fixed-angle equipment

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent implements parameter changes by enabling the bending angle to be adjusted between different values. The bending control unit allows the bending angle parameter to be changed based on the surgical procedure being performed, transforming a static parameter into a dynamic one that can be optimized for different application scenarios, thus achieving multi-functionality with a single device

Inventive Principle:
Principle #35Parameter changes

2Productivity

If multiple detachable endoscopes are provided for different surgeries, then each device is optimized for its specific use, but maintenance and purchase costs increase

Engineering Contradiction:
Improveequipment utilization efficiencyVSAvoidnumber of endoscope devices
Core Design Contradiction:
ProductivityVSQuantity of substance

Solution Approach 1:

The patent applies the universality principle by designing a detachable endoscope that can perform multiple functions - serving as both a gastric endoscope and a colonofiberscope. The insertion part is designed with adjustable bending capabilities that allow it to function in different surgical scenarios, replacing the need for multiple specialized devices and improving equipment utilization efficiency

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

Solution Approach 2:

The patent implements merging by combining the functionalities of what were previously separate gastric endoscope and colonofiberscope into a single unified device. The detachable design allows the insertion part to be used across different operation parts, merging multiple surgical capabilities into one system and reducing the total number of devices required

Inventive Principle:
Principle #5Merging (Combining)

3Reliability

If an integrally composed endoscope is used, then the structure is stable and reliable, but the insertion part cannot be separated for replacement or disinfection

Engineering Contradiction:
Improvesystem stabilityVSAvoidinsertion part replaceability
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent applies the segmentation principle by dividing the endoscope into separable components - specifically, the insertion part can be detached from the operation part. This segmentation maintains the reliability of the overall system while enabling the insertion part to be independently replaced, disinfected, or maintained without affecting the operation part, thus improving ease of operation

Inventive Principle:
Principle #1Segmentation
