Solution Overview

Problem

Existing pumping apparatuses for materials like concrete transmit high vibrations and oscillations to the bearing structure, leading to mechanical stress, premature deterioration, and instability, especially when used on heavy vehicles with extended outlet pipes, posing safety risks.

Innovation Solution

The introduction of damping means, comprising multiple damper elements made of elastic materials like rubber, strategically positioned between the pumping unit and the bearing structure to absorb and prevent the translation and roll of the pumping unit, thereby reducing vibrations and improving stability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If the pumping unit is rigidly attached to the bearing structure, then the structural strength and stability are improved, but high vibrations and oscillations are transmitted to the bearing structure, causing mechanical stress and premature deterioration

Engineering Contradiction:
Improvestructural strengthVSAvoidvibrations and oscillations
Core Design Contradiction:
StrengthVSObject-affected harmful factors

Solution Approach 1:

The patent introduces a bearing assembly as an intermediary component between the pumping unit and the bearing structure. This bearing assembly includes damping elements that absorb and reduce vibrations and oscillations generated by the pumping unit, preventing them from being transmitted to the bearing structure while still maintaining structural support and stability.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Object-affected harmful factors

If damping elements are added to reduce vibrations, then the transmission of vibrations to the bearing structure is reduced, but the device complexity increases

Engineering Contradiction:
Improvevibrations transmitted to bearing structureVSAvoiddevice complexity
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The patent merges the damping function with the bearing support function by integrating damping elements into the bearing assembly. This combination allows the same structural component to serve dual purposes: supporting the pumping unit and reducing vibrations, thereby minimizing the increase in device complexity while achieving effective vibration reduction.

Inventive Principle:
Principle #5Merging (Combining)
