Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The installation of side-mounted rotary machines for mixing, pumping, or agitating fluids is laborious and time-consuming due to the need for precise adjustment and cutting of support structures to match varying distances between the machine and the foundation, which complicates relocation and adaptation.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the support structure legs are made fixed length, then the manufacturing and initial installation are simpler, but the adaptability to different installation locations and distances is poor
Solution Approach 1:
The support structure transitions from a fixed-length design to a dynamically adjustable design. The telescopic legs with inner and outer tubes allow the support length to be varied according to different installation requirements, resolving the contradiction between manufacturing simplicity and installation adaptability.
Solution Approach 2:
The leg length parameter is made variable through the telescopic mechanism. By changing the extension distance of the inner tube relative to the outer tube, the support structure can adapt to different vertical distances between the rotary machine and the foundation, while maintaining a standardized base design for manufacturing.
2Adaptability or versatility
If the support structure legs are made adjustable length with telescopic design, then the adaptability to different installation locations is improved, but the device complexity increases
Solution Approach 1:
The telescopic leg employs a nested tube structure where an inner tube is housed within an outer tube. This nesting arrangement provides adjustability while maintaining a compact form and relatively simple construction, minimizing the increase in device complexity.
Solution Approach 2:
The leg is divided into separate segments (inner tube and outer tube) that can move relative to each other. This segmentation enables length adjustment while keeping each component individually simple, avoiding the need for complex mechanical systems.
3Manufacturing precision
If the support structure requires cutting and welding for length adjustment, then the initial fit can be precise, but the installation time and labor requirements increase significantly
Solution Approach 1:
The support structure allows for dynamic adjustment of leg length through the telescopic mechanism, eliminating the need for static cutting and welding operations during installation. This reduces installation time while maintaining precision through the adjustable design.
Solution Approach 2:
The telescopic mechanism is pre-configured to provide adjustable length, so the precision fitting is built into the design rather than requiring post-manufacturing modifications like cutting and welding. The adjustment capability is prepared in advance, reducing on-site work.
4Adaptability or versatility
If the support structure is designed for easy adjustment, then the relocation flexibility is improved, but the structural stability may be compromised
Solution Approach 1:
The nested tube design provides a compact, integrated structure that maintains stability. When the telescopic leg is extended to the required length and locked in position, the nested construction ensures structural rigidity while allowing for future adjustment or relocation.
Solution Approach 2:
The support structure is designed to be dynamically adjustable during installation and relocation, but once positioned, it provides stable support. The telescopic mechanism allows for controlled adjustment while maintaining structural integrity during normal operation.
