Integrated Concrete Pump Drive Unit with Valve Block
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing concrete pump units are not compact, lightweight, or reliable due to separate hydraulic components, flexible hoses that age and leak under pressure, and high installation space requirements, especially in mobile truck-mounted applications.
Innovation Solution
A concrete pump unit with integrated valve technology and fixed piping between drive cylinders, eliminating the need for flexible hoses and forming a compact, torsion-resistant structural unit with pre-assembled drive cylinders and connecting means, such as valve blocks, which also house switching elements and sensors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If flexible hoses are used to connect drive cylinders and hydraulic components, then the system can be assembled individually with separate components, but the hoses are subject to aging, can move unintentionally under pressure loads, pose a risk of leaks, and reduce the response time of the system
Solution Approach 1:
The patent combines separate hydraulic components (drive cylinders, valve blocks, piping) into a single integrated concrete pump unit with a common housing. This merging eliminates flexible hoses and their associated reliability problems while maintaining assembly feasibility through modular sub-components.
2Ease of manufacture
If flexible hoses are used to connect individual drive components, then the components can be assembled separately, but the elasticity of hoses reduces the desired rapid response time of the overall system
Solution Approach 1:
The integration of hydraulic components into a single rigid structure eliminates the elasticity and compliance of flexible hoses, thereby achieving rapid response times while still allowing for practical assembly of modular sub-components within the integrated unit.
3Ease of manufacture
If separate hydraulic components and flexible hoses are used, then the system can be assembled in parts, but the large amount of space required for individual components has a negative impact in the confined spaces of a mobile truck-mounted concrete pump
Solution Approach 1:
The patent integrates all hydraulic components into a compact unified structure with a common housing, dramatically reducing the overall volume required for the drive system while maintaining the ability to assemble modular sub-components.
4Ease of manufacture
If separate hydraulic components are used, then the system can be assembled individually, but the multitude of individual components leads to an increase in the weight of the concrete pump unit
Solution Approach 1:
The integration of hydraulic components into a single unit with common housing and shared structural elements eliminates redundant components and reduces overall weight, while still allowing for modular assembly of sub-components.
