Solution Overview

Problem

Conventional endoscope devices with LED illumination face challenges in efficiently integrating LED chips with objective lens groups, leading to increased diameter and complexity, which affects optical characteristics and ease of assembly and maintenance.

Innovation Solution

The endoscope device separates the objective lens group into two parts, with one part mounted on an LED supporting block, allowing for easier placement of LED chips and reducing the outer diameter of the LED supporting block, while enabling easy attachment and detachment of the LED supporting block from a lens supporting block via a positioning device and electrical connection system.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Volume of moving object

If LED chips are directly mounted on a separate supporting block from the objective lens group, then the outer diameter of the LED supporting block can be reduced, but the device complexity increases due to separate mounting structures

Engineering Contradiction:
Improveouter diameter of LED supporting blockVSAvoidstructure complexity
Core Design Contradiction:
Volume of moving objectVSDevice complexity

Solution Approach 1:

The patent merges the LED supporting block and lens supporting block into a single integrated structure. The LED chips are mounted on the front surface of the supporting block, while the objective lens group is mounted on the rear surface, eliminating the need for separate mounting structures and reducing overall device complexity while maintaining compact dimensions

Inventive Principle:
Principle #5Merging (Combining)

2Ease of operation

If the objective lens group is separated from the LED supporting block, then assembly and maintenance become easier, but the optical characteristics may be affected

Engineering Contradiction:
Improveease of assembly and maintenanceVSAvoidoptical characteristics
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The supporting block is divided into distinct functional regions: a front surface for LED chip mounting and a rear surface for objective lens group mounting. This segmentation allows independent assembly and maintenance of LED components and optical components while maintaining precise relative positioning through the integrated block structure, preserving optical characteristics

Inventive Principle:
Principle #1Segmentation

3Volume of moving object

If multiple components are integrated into a single supporting block, then the overall device diameter is reduced, but the manufacturing precision requirements increase

Engineering Contradiction:
Improveoverall device diameterVSAvoidmounting precision
Core Design Contradiction:
Volume of moving objectVSManufacturing precision

Solution Approach 1:

By integrating both LED mounting and lens mounting functions into a single supporting block, the patent reduces the overall device diameter. The block's rigid structure provides stable, pre-defined mounting positions that simplify the manufacturing process compared to coordinating multiple separate components, thereby managing precision requirements effectively

Inventive Principle:
Principle #5Merging (Combining)
