Solution Overview

Problem

Existing adapter systems for geared motors lack versatility and efficiency, particularly in terms of compact design and additional features like improved sealing and freewheel functionality.

Innovation Solution

The development of a series of adapters for geared motors, featuring a first adapter with a compact design and a second adapter with an intermediate flange for enhanced sealing or freewheel integration, allowing for customizable solutions without additional effort.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Volume of moving object

If a compact adapter design is used, then the device size is reduced, but additional features like sealing and freewheel functionality cannot be integrated

Engineering Contradiction:
Improveadapter sizeVSAvoidsealing and freewheel functionality
Core Design Contradiction:
Volume of moving objectVSAdaptability or versatility

Solution Approach 1:

The adapter is divided into modular components: a basic compact adapter body and optional intermediate flanges. These segments can be selectively assembled to create different adapter configurations, allowing the same basic design to serve both compact and feature-enhanced applications.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The intermediate flange is designed as a universal component that can serve multiple functions: providing sealing surfaces for shaft seal rings, accommodating freewheel mechanisms, and maintaining structural integrity. This single component enables the adapter to adapt to different functional requirements without requiring completely different designs.

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

2Adaptability or versatility

If different adapter configurations are produced for different applications, then application-specific functionality is achieved, but manufacturing complexity increases

Engineering Contradiction:
Improveapplication-specific functionalityVSAvoidmanufacturing complexity
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

By segmenting the adapter into standardized modules (basic adapter body, intermediate flanges with different configurations), the manufacturing process is simplified. Each module can be produced independently using the same tooling and processes, then assembled to create application-specific variants.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Different adapter configurations are achieved by varying parameters such as the presence or absence of intermediate flanges, rather than redesigning the entire adapter. This allows manufacturers to produce different versions by changing assembly parameters rather than manufacturing parameters.

Inventive Principle:
Principle #35Parameter changes

3Adaptability or versatility

If an intermediate flange is added for sealing or freewheel features, then functionality is improved, but the adapter becomes more complex

Engineering Contradiction:
Improvesealing and freewheel functionalityVSAvoidadapter structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The intermediate flange acts as an intermediary component between the basic adapter body and the shaft seal ring or freewheel. It provides a standardized interface that simplifies the integration of additional features while maintaining a clear separation of functions, thereby managing complexity through modular mediation.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

In an adapter series for geared motors, and a method for producing an adapter from a modular system, which include a first housing part, a second housing part, an intermediate flange, and a first bearing, a first adapter or a second adapter is selectively produced. To produce the first adapter, the first housing part is directly connected to the second housing part, and the outer ring of the first bearing is accommodated in the first and second housing parts and centers the first housing part with respect to the second housing part. To produce the second adapter, the first housing part is connected directly to the intermediate flange, the intermediate flange is connected directly to the second housing part on the side thereof facing away from the first housing part, and the outer ring of the first bearing is accommodated in the first housing part and in the intermediate flange and centers the first housing part with respect to the intermediate flange.
