Solution Overview

Problem

The production of endoscopes and their Y-connectors is cost-intensive and challenging due to the need for complex moulding with core parts, particularly rotational core parts, which limits design freedom and increases tooling costs, making it difficult to assemble and replace components efficiently.

Innovation Solution

A modular endoscope design featuring a multi-piece Y-connector that can be separately produced and assembled, eliminating the need for rotational core mould pieces during production, allowing for easier assembly and replacement, and reducing tooling costs through a two-piece configuration that can be moulded without core mould pieces or with only straight core mould pieces.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If a Y-connector is integrally formed directly on the endoscope handle using complex moulding with rotational core parts, then the connector achieves a unified structure, but the production cost increases significantly and design freedom is limited

Engineering Contradiction:
Improveunified structureVSAvoidproduction cost
Core Design Contradiction:
Stability of the object's compositionVSEase of manufacture

Solution Approach 1:

The connector is divided into multiple separate components: a first component (Y-connector body) and a second component (cover element). These components are produced separately using simple moulding processes without requiring expensive rotational core parts, then assembled together to form the complete connector assembly, thereby reducing tooling costs while maintaining structural integrity

Inventive Principle:
Principle #1Segmentation

2Stability of the object's composition

If a Y-connector is integrally formed directly on the endoscope handle, then the connector structure is fixed, but the assembly and replacement of components becomes difficult

Engineering Contradiction:
Improveconnector structureVSAvoidassembly and replacement
Core Design Contradiction:
Stability of the object's compositionVSEase of repair

Solution Approach 1:

The connector is segmented into a first component and a second component that can be separately assembled and disassembled. The second component (cover element) can be removed to access the first component (Y-connector body) and the biopsy channel, enabling easy maintenance, cleaning, and replacement of internal components while maintaining the overall connector structure

Inventive Principle:
Principle #1Segmentation

3Manufacturing precision

If complex rotational core mould pieces are used to produce the Y-connector, then the connector geometry is achieved, but the tooling costs increase significantly

Engineering Contradiction:
Improveconnector geometryVSAvoidtooling costs
Core Design Contradiction:
Manufacturing precisionVSEase of manufacture

Solution Approach 1:

The connector production process is segmented into two separate moulding operations, each using simple straight core mould pieces instead of expensive rotational cores. The first component is moulded with a straight core, then the second component is moulded separately and assembled, achieving the required Y-connector geometry without requiring complex rotational core tooling

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The second component (cover element) acts as an intermediary that, when assembled with the first component (Y-connector body), creates the complete connector geometry. This approach allows the complex Y-shape to be achieved through assembly of two simple components rather than through complex single-piece moulding

Inventive Principle:
Principle #24Intermediary (Mediator)
