Solution Overview

Problem

Mobile concrete pumps face challenges in optimizing the use of space on the chassis while maintaining the strength and stability of outriggers, which are crucial for supporting the working units without tipping, and existing transverse openings do not adequately address this space-saving need.

Innovation Solution

Designing at least one transverse opening in the support arms as a housing that can be closed with a cover, allowing for the integration of auxiliary units like hydraulic coolers, and utilizing the hollow chamber as a liquid tank, which also serves as additional storage space.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of substance

If transverse openings are provided in support arms to reduce material usage and weight, then material saving is achieved, but the outriggers take up more space on the chassis

Engineering Contradiction:
Improvematerial usageVSAvoidloading area
Core Design Contradiction:
Loss of substanceVSArea of stationary object

Solution Approach 1:

The patent merges the transverse opening structure with auxiliary units (hydraulic cooler, tool boxes, couplings) by designing the opening as a housing that can accommodate these components. This integration allows the outrigger to serve both structural and functional purposes simultaneously, reducing material usage while avoiding additional space consumption on the chassis.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The transverse opening is designed to serve multiple functions: it reduces material usage for weight reduction, provides structural stiffness through its opening walls, and accommodates auxiliary units such as hydraulic coolers, tool boxes, and couplings. This multi-functionality resolves the contradiction by making the same structural feature serve several purposes without requiring additional space.

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

2Stability of the object's composition

If transverse openings with opening walls are used in support arms, then structural stiffness is maintained, but space on the chassis is reduced

Engineering Contradiction:
Improvestructural stiffnessVSAvoidloading area
Core Design Contradiction:
Stability of the object's compositionVSArea of stationary object

Solution Approach 1:

The opening walls of the transverse opening are designed to serve dual purposes: maintaining structural stiffness and providing housing for auxiliary units. By merging these functions into a single structural feature, the patent avoids the need for separate stiffening elements that would consume additional chassis space.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The transverse opening structure is designed to simultaneously provide structural stiffness through its opening walls and accommodate auxiliary units. This multi-functional design resolves the contradiction by making the stiffening structure itself serve as housing, eliminating the need for additional space-consuming components.

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

3Area of stationary object

If auxiliary units are integrated into the transverse opening housing, then space is saved on the chassis, but the device complexity increases

Engineering Contradiction:
Improveloading areaVSAvoiddevice complexity
Core Design Contradiction:
Area of stationary objectVSDevice complexity

Solution Approach 1:

The patent merges auxiliary units (hydraulic cooler, tool boxes, couplings) into the transverse opening housing structure. This integration reduces the overall space requirement on the chassis while managing complexity by utilizing the existing opening structure as the housing, thereby avoiding the need for separate housings and reducing the number of discrete components.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

The invention relates to a mobile work appliance, in particular to an automatic concrete pump. The work appliance substantially comprises a chassis (12), two front and two rear supporting jibs (38, 40) which are extendable relative to the chassis (12) from a transport position into at least one working position and are each supportable by a supporting leg (42) on a base, with the chassis being raised, and a drive unit (47) for controlling working assemblies and/or the supporting jibs. A particular characteristic of the invention is that at least one of the supporting jibs (40) having a support or hollow chamber profile has a transverse aperture (48) which can be designed, for example, as a housing for an auxiliary assembly (52) of the drive unit.
