Solution Overview

Problem

Existing mobile cranes face challenges in attaching auxiliary tips to booms with different system dimensions, requiring additional adapters that increase assembly effort and weight.

Innovation Solution

The auxiliary tip features multiple connecting elements with varying system dimensions, allowing direct attachment to booms without adapters, including first, second, and optionally third connecting elements, enabling flexibility in mounting on different boom parts.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If adapters are used to attach auxiliary tips to booms with different system dimensions, then compatibility with different boom parts is improved, but assembly effort and weight increase

Engineering Contradiction:

Improvecompatibility with different boom partsVSAvoidassembly effort

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The auxiliary tip is designed with multiple connecting elements (first, second, and optionally third connecting elements) that have different system dimensions, allowing the same auxiliary tip to be directly attached to different boom parts (pulley head, luffing tip, or telescopic boom end) without requiring adapters. This multi-functional design resolves the contradiction by providing universal compatibility while maintaining simple assembly procedures.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If adapters are used to attach auxiliary tips to booms with different system dimensions, then compatibility with different boom parts is improved, but weight increases

Engineering Contradiction:

Improvecompatibility with different boom partsVSAvoidweight

Core Design Contradiction:

Adaptability or versatilityVSWeight of moving object

Solution Approach 1:

The auxiliary tip integrates multiple connecting elements with different system dimensions directly into its structure, eliminating the need for separate adapters. This allows the auxiliary tip to be directly attached to different boom parts while avoiding the additional weight that would be introduced by adapter components.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Adaptability or versatility

If multiple connecting elements with different system dimensions are integrated into the auxiliary tip, then adaptability to different boom parts is improved, but manufacturing complexity increases

Engineering Contradiction:

Improveadaptability to different boom partsVSAvoidmanufacturing complexity

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

Multiple connecting elements with different system dimensions are merged into a single integrated auxiliary tip structure. This combining approach allows the auxiliary tip to adapt to different boom parts while streamlining manufacturing, as the connecting elements are produced as part of the same component rather than requiring separate adapter assemblies.

Inventive Principle:

Principle #5Merging (Combining)

AI summary

The invention relates to an auxiliary tip for detachable mounting on a boom of a work machine, in particular a mobile crane. The auxiliary tip comprises first connecting elements for establishing a first connection with a first boom part, and second connecting elements for establishing a second connection with the first boom part. In order to be able to connect the auxiliary tip to a second boom part having a system dimension different from the first boom part, the auxiliary tip according to the invention comprises third connecting elements with which a second connection to a second boom part can be established instead of the second connecting elements. While the auxiliary tip is connected to the first boom part via the first and second connecting elements, the auxiliary tip can be releasably connected to a second boom part via the third connecting elements.
