Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical cable protection systems for submerged pumps are cumbersome and time-consuming to assemble, particularly for handheld pumps that require rapid installation and use under emergency conditions, and they do not meet the requirements for reliability and ease of use.
Innovation Solution
The use of quick fixing devices with resilient tails and bayonet sliding triggers that allow for easy assembly and disassembly of electrical cable protection means by simple radial pressure, which are securely attached to the pump's cylindrical lateral wall, enabling rapid and stable blocking and releasing of the protection means.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If screw-type connection means are used to attach cable protection means to the pump body, then the connection is secure and reliable, but the assembly and disassembly process becomes slow and difficult
Solution Approach 1:
The patent replaces static screw connections with dynamic quick-fixing devices that can be rapidly engaged and disengaged. The resilient tail mechanism allows the protection means to be securely attached during operation while enabling fast removal when needed, thus resolving the contradiction between connection reliability and assembly speed.
Solution Approach 2:
The invention extracts the complex screw connection mechanism and replaces it with a simplified quick-fixing system. By removing the time-consuming screw assembly process while maintaining secure attachment through the resilient tail engagement, the patent achieves both reliability and speed.
2Reliability
If screw-type connection means are used to attach cable protection means to the pump body, then the connection is secure, but the operation becomes complex and difficult
Solution Approach 1:
The quick-fixing devices with resilient tails automatically engage with the pump body without requiring manual screw tightening. The resilient nature of the tails provides self-adjusting secure attachment, making the operation simple and intuitive while maintaining reliable connection.
Solution Approach 2:
The dynamic resilient tail mechanism adapts to the pump body surface, providing secure connection through elastic deformation rather than rigid screw fastening. This makes the operation easier while maintaining connection stability.
3Productivity
If handheld submerged pumps are designed for rapid installation and use under emergency conditions, then the response time is reduced, but the cable protection system must be simplified from complex screw-type connections
Solution Approach 1:
The cable protection system is segmented into modular components: the protection means and the quick-fixing devices with resilient tails. This segmentation allows for simple, rapid attachment and detachment, significantly improving installation speed while reducing overall system complexity.
Solution Approach 2:
The dynamic quick-fixing mechanism enables rapid deployment of the cable protection system, allowing handheld pumps to be quickly installed and used under emergency conditions without complex assembly procedures.
