Solution Overview

Problem

Existing frames for high-density concrete distribution booms require complex welding for mast support attachment, leading to inflexible manufacturing and high transport costs.

Innovation Solution

A detachable bolt connection between the mast support and support profiles, utilizing tab elements with through-holes and bolt receptacles, eliminates the need for welding, allowing separate transport and flexible assembly.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If welding is used to attach the mast support to the support profiles, then the connection strength and stability are improved, but the manufacturing complexity and transport costs increase

Engineering Contradiction:
Improveconnection strengthVSAvoidmanufacturing complexity
Core Design Contradiction:
StrengthVSDevice complexity

Solution Approach 1:

The connection system is segmented into separate components: the mast support with tab elements and the support profiles with bolt receptacles. This allows the mast support to be detached from the support profiles, enabling separate transport and simplified manufacturing. The segmentation maintains connection strength through the bolt-b tab element-receptacle assembly while eliminating the need for complex welding operations.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The tab elements with through-holes serve as intermediaries between the mast support and the support profiles. These tab elements transmit forces from the mast to the support profiles through bolt connections, replacing the direct welded connection. The intermediary tab elements simplify the connection process while maintaining structural integrity.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Stability of the object's composition

If welding is used to attach the mast support to the support profiles, then the connection stability is improved, but the transport flexibility and manufacturing flexibility decrease

Engineering Contradiction:
Improveconnection stabilityVSAvoidtransport flexibility
Core Design Contradiction:
Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

By segmenting the mast support from the support profiles through the use of detachable tab elements, the system enables flexible transport configurations. The mast support can be removed and transported separately or attached at different locations, while the bolt connection ensures stability when assembled. This segmentation directly addresses both transport flexibility and connection stability requirements.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The connection system transitions from a static welded joint to a dynamic, reconfigurable bolt connection. The tab elements with through-holes allow the mast support to be attached, detached, and repositioned as needed, providing adaptability for different transport and assembly scenarios while maintaining stable connection when assembled through the bolt-b tab element-receptacle mechanism.

Inventive Principle:
Principle #15Dynamics

3Strength

If complex welding operations are performed, then the connection strength is improved, but the production time and cost increase

Engineering Contradiction:
Improveconnection strengthVSAvoidproduction efficiency
Core Design Contradiction:
StrengthVSProductivity

Solution Approach 1:

The segmentation of the mast support into separate tab elements that attach via bolts rather than welding dramatically reduces production time. The tab elements can be pre-fabricated and then quickly attached to support profiles using simple bolt connections, eliminating lengthy welding operations while maintaining adequate connection strength for the application.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The tab elements are designed as simple, inexpensive components that can be quickly manufactured and attached. Rather than investing time and resources in complex welding operations, the invention uses simple bolt-connected tab elements that achieve the necessary connection strength with minimal production time and cost.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

AI summary

The subject of the present invention is a frame (12) with a boom pedestal (17) for mounting a thick matter distribution boom (20) and having a support profile (13) for receiving and transmitting a force flow generated by the weight force of the thick matter distribution boom (20). The boom pedestal (17) has two tab elements (21, 22) which project downwards from the boom pedestal (17) and which each have a through-hole (23, 24), wherein the support profile (13) comprises a bolt receptacle (14) aligned with the through-holes, and wherein a bolt element (15) for connecting the boom pedestal (17) to the support profile (13) is guided through the through-holes (23, 24) and the bolt receptacle (14). The invention further relates to a corresponding thick matter pump equipped with said frame. The transportation effort required in production can be reduced by means of the bolt connection.
