Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If a vibration damping element is integrated into the adapter part, then vibration reduction is improved, but device complexity increases

Engineering Contradiction:
ImprovevibrationsVSAvoiddevice complexity
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The adapter part is designed to serve multiple functions: it acts as a structural connector between housing parts, provides vibration damping through an integrated damping element, and offers modular functionality where additional components can be attached. This multi-functionality reduces the need for separate vibration damping devices while maintaining the damping effect.

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

Solution Approach 2:

The adapter part functions as an intermediary component between the housing parts and the vibration damping element. It provides a standardized interface that allows the damping element to be integrated without requiring direct modification of the housing parts, thus simplifying the overall structure while maintaining damping performance.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If the adapter part uses standardized connection elements, then ease of installation is improved, but adaptability for different functionalities decreases

Engineering Contradiction:
Improveease of installationVSAvoidadaptability
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The adapter part is segmented into distinct functional zones: standardized connection elements for easy installation, a core damping function, and modular attachment interfaces for additional functionalities. This segmentation allows the standardized connection to coexist with specialized functional attachments, resolving the contradiction between ease of installation and adaptability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The adapter part incorporates dynamic characteristics through its vibration damping element that can adapt to different operational conditions. The standardized connection provides static reliability, while the damping element provides dynamic vibration reduction, and additional modules can be dynamically attached or removed as needed.

Inventive Principle:
Principle #15Dynamics

3Device complexity

If the adapter part is designed as a single integrated component, then device complexity is reduced, but ease of repair decreases

Engineering Contradiction:
Improvedevice complexityVSAvoidease of repair
Core Design Contradiction:
Device complexityVSEase of repair

Solution Approach 1:

The adapter part is designed with modular segmentation, separating the connection elements, damping element, and functional attachments into distinct replaceable components. This allows the connection interfaces to remain standardized and simple while enabling individual components to be replaced or repaired independently, thus maintaining ease of repair despite the integrated design.

Inventive Principle:
Principle #1Segmentation

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

The adapter part effectively reduces vibrations and noise, allowing for quick installation and removal, and can be combined with other functional elements to enhance machine tool performance, providing a robust and versatile solution for vibration reduction and additional functionalities.

Implementation Method 1

the adapter ring is designed to be elastically deformable. This design is particularly suitable for a functional element that is designed as a vibration damping element, since the inherent elasticity of the adapter ring causes deformation due to the vibrations or impacts that occur, and these deformations are reduced in the vibration damping element.

Methodology Applied
