Concrete Pump Mast Base Device Space Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing self-driving mobile concrete pumps inefficiently utilize available installation space and face challenges during transportation due to the separate distribution of machine functions and the design of auxiliary frames.
Innovation Solution
Integration of machine functions into a multifunctional mast base device, which serves as a pre-assembled group that can be easily attached to and detached from the auxiliary frame, allowing for better space utilization and simplified transportation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If machine functions are distributed separately throughout the concrete pump, then each function can be independently maintained and accessed, but valuable installation space is wasted and the overall structure becomes complex
Solution Approach 1:
The patent combines multiple machine functions (control cabinet, hydraulic valves, lighting, coolers, displays, and boom support) into a single integrated boom support frame structure. This merging of previously distributed components into one consolidated unit optimizes installation space utilization while reducing the number of separate structural elements required.
Solution Approach 2:
The boom support frame is designed as a multifunctional assembly that simultaneously serves as a structural support for the placing boom and houses various machine functions including control systems, hydraulic components, and cooling devices. This multi-functionality eliminates the need for separate dedicated structures for each function.
2Stability of the object's composition
If the boom support frame is firmly welded to the subframe, then structural stability is improved, but the frame becomes difficult to transport and assemble
Solution Approach 1:
The connection between the boom support frame and subframe is designed to be changeable - firmly connected during operation for stability, but detachable during transport for ease of movement. This dynamic connection approach allows the structure to adapt between operational and transport states.
Solution Approach 2:
The boom support frame with integrated functional units is designed as a separable module that can be detached from the subframe. This segmentation allows the functional units to be transported separately or as an assembly, significantly simplifying shipping and assembly operations while maintaining structural integrity during use.
3Strength
If the subframe comprises two parallel longitudinal beams forming a large H-shape, then structural strength is improved, but transportation becomes difficult
Solution Approach 1:
The subframe system is divided into separable components - the longitudinal beams and the boom support frame with functional units can be detached from each other. This segmentation maintains the structural strength of the H-shaped subframe during operation while enabling simplified transportation by removing the functional unit assembly.
Solution Approach 2:
The boom support frame containing the functional units is extracted as a separate removable component from the subframe structure. This extraction allows the subframe to be transported in its basic H-shaped configuration while the functional units can be transported separately or attached to the vehicle chassis, significantly improving transportation ease.
