Underwater Cable Clip with Telescopic Sealing and Unidirectional Tracks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cable clip devices fail to simultaneously facilitate convenient disassembly and reliable sealing of power cables in underwater applications, particularly affecting the appearance and functionality of electrical appliances like pet water dispensers.
Innovation Solution
A cable clip device with an outer cylindrical column, first and second inner cylindrical columns, a spring, and a cover, featuring unidirectional tracks and a sealing ring that allows for secure sealing and easy disassembly by using a hook portion and pull rod mechanism, enabling the cable to be sealed and easily removed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the power cable passes through the wall of the water tank to the outside, then the sealing reliability is improved, but the disassembly convenience deteriorates
Solution Approach 1:
The device divides the cable management system into separate functional modules: a fixed outer cylindrical column with sealing structure, and a removable inner cylindrical column containing the cable. This segmentation allows the sealing function to remain integrated with the tank wall while the cable access function becomes independently removable, resolving the contradiction between maintaining reliable sealing and enabling convenient disassembly.
Solution Approach 2:
The inner cylindrical column containing the power cable is extracted as a separate removable component from the outer cylindrical column that remains fixed to the tank wall. This extraction allows the cable to be easily removed by taking out the inner column, while the outer column maintains the sealing connection with the tank wall, thus achieving both disassembly convenience and sealing reliability.
2Ease of operation
If the power cable protrudes from the top of the water tank, then the disassembly convenience is improved, but the appearance deteriorates
Solution Approach 1:
The device employs a nested structure where the inner cylindrical column containing the cable is placed inside the outer cylindrical column. The outer column serves as a protective housing that conceals the cable and internal components, providing a clean, streamlined appearance similar to the tank itself, while the nested design allows easy removal of the inner column for cable access.
3Ease of operation
If the cover is detachably arranged above the second inner cylindrical column, then the disassembly convenience is improved, but the sealing reliability deteriorates
Solution Approach 1:
The sealing ring is pre-installed on the outer cylindrical column at the sealing surface before the inner cylindrical column is inserted. This preliminary positioning ensures that when the inner column is inserted, the sealing interface is already prepared and aligned, maintaining reliable sealing while allowing the cover and inner column to be easily detached when needed.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The device ensures reliable sealing of cables when in use and allows for convenient disassembly and reinstallation, preventing water ingress and maintaining the appearance of underwater electrical appliances.
Implementation Method 1
the spring provides an elastic force for the second inner cylindrical column to slide obliquely upwards
Implementation Method 2
the sealing ring abuts against and seals an inner surface of the outer cylindrical column
