Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing liquid movement devices, such as centrifugal pumps, are complex to disassemble and assemble, making maintenance and repair difficult, and they have large sizes during transport and storage, leading to high costs.
Innovation Solution
A device for moving liquids with a bayonet coupling mechanism between the drive and hydraulic units, allowing for rapid and secure connection and disconnection, and a support base with snap-in fastening means for stable attachment, facilitating easy maintenance and reduced size for transport and storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the device is supplied as a single piece with integrated components, then the structural stability and reliability are improved, but the device complexity increases and maintenance becomes difficult
Solution Approach 1:
The device is divided into separate modular components (drive unit, hydraulic unit, support base) that can be assembled and disassembled independently. The drive unit can be detached from the hydraulic unit, and the hydraulic unit can be removed from the support base, allowing maintenance of individual components without affecting the entire system.
2Reliability
If the device is supplied as a single piece, then the structural integrity is improved, but the ease of repair deteriorates
Solution Approach 1:
The device is divided into separate modular components (drive unit, hydraulic unit, support base) that can be assembled and disassembled independently. The drive unit can be detached from the hydraulic unit, and the hydraulic unit can be removed from the support base, allowing maintenance of individual components without affecting the entire system.
Solution Approach 2:
The drive unit is designed to be extractable from the hydraulic unit through a coupling mechanism. This allows the drive unit to be removed for maintenance or replacement while leaving the hydraulic unit in place, significantly improving ease of repair.
3Stability of the object's composition
If the device is completely assembled in a single piece, then the structural stability is improved, but the transport cost increases due to large size
Solution Approach 1:
The device is divided into separate modular components (drive unit, hydraulic unit, support base) that can be transported independently or in smaller assemblies, reducing the overall transport volume and cost while maintaining structural stability through standardized coupling mechanisms.
Solution Approach 2:
The coupling mechanisms are designed to nest components together during operation, creating a compact integrated structure that maintains stability while allowing separation for transport. The drive unit nests with the hydraulic unit, and the hydraulic unit nests with the support base.
4Reliability
If the device is completely assembled in a single piece, then the structural integrity is improved, but the storage space requirement increases
Solution Approach 1:
The device is divided into separate modular components that can be stored in smaller, more manageable volumes. When not in use, components can be stored separately or in nested configurations, significantly reducing the total storage space required while maintaining structural integrity through standardized coupling mechanisms.
