Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions for sealing cables, pipes, or wires through partitions, such as tank walls, often fail to provide a reliable, easy-to-install, and retrofitable solution that prevents leakage and allows for cable replacement.
Innovation Solution
A transit system comprising a sleeve and a compressible seal with movable fittings that compress to create a radial expansion for sealing, allowing axial restraint and easy installation from one side of the partition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional sealed cable passage is used, then leakage prevention is achieved, but cable replacement becomes difficult and installation complexity increases
Solution Approach 1:
The seal is divided into multiple segments or layers that can be independently manipulated. The cable can be extracted from the seal without destroying the seal structure, allowing cable replacement while maintaining the sealing capability. The seal comprises a base part and at least one sheet that can be separated during cable replacement operations.
Solution Approach 2:
The seal is designed with dynamic characteristics that allow it to adapt during cable installation and replacement. The compressible base part can deform to accommodate cable movement, and the fittings allow for adjustable compression forces, enabling the seal to maintain reliability while facilitating maintenance operations.
2Reliability
If a complex sealing mechanism is used, then sealing reliability is improved, but device complexity and installation difficulty increase
Solution Approach 1:
The seal is designed to be self-installing within the sleeve structure. The compressible base part automatically expands or contracts to engage with the sleeve inner surface, and the fittings can be adjusted to apply compression forces without requiring external tools or complex assembly procedures. The seal serves its own installation needs through its inherent elastic properties.
Solution Approach 2:
The sealing mechanism utilizes changes in physical parameters, specifically the compression force applied to the base part. By adjusting the compression force through the fittings, the seal transitions between different states of compression, allowing for simple installation and adjustment while maintaining reliable sealing. The compressible nature of the base part enables parameter-based control of sealing performance.
3Reliability
If the seal is made compressible for better sealing, then sealing effectiveness improves, but axial restraint becomes difficult
Solution Approach 1:
The solution transitions the restraint mechanism from axial to radial dimension. Instead of restraining the seal axially through rigid structures, the invention uses the radial expansion of the compressible base part against the sleeve inner surface to provide restraint. The groove structure in the sleeve provides radial support that prevents excessive axial movement while allowing the seal to maintain its compressible nature for effective sealing.
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 system effectively seals cables, pipes, or wires by compressing the seal to expand radially, preventing leakage while allowing for easy installation and retrofitting, ensuring a secure and leak-proof connection.
Implementation Method 1
The front and rear fittings are arranged in such a way that they can be moved towards each other to compress the base part of the seal
