Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing telecommunications closure sealing systems are not adequately efficient in preventing environmental exposure, such as moisture intrusion, and often require complex screwing mechanisms that can lead to installation errors and leaks.
Innovation Solution
The introduction of a compression/lever mechanism within end caps that utilizes a cam or biasing element to apply defined compression forces, simplifying and speeding up the installation process while preventing operator mistakes, and ensuring a secure environmental seal through a spring-activated compression mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a screwing mechanism is used to compress cable seals, then the sealing function can be achieved, but the installation process becomes complex and error-prone
Solution Approach 1:
The patent replaces the traditional screwing mechanism with a compression mechanism that uses a compression element and biasing element to apply radial compression force directly to the cable seal. This substitution eliminates the need for threaded fasteners and manual tightening operations, reducing installation complexity while maintaining sealing reliability through controlled compression forces.
Solution Approach 2:
The patent changes the compression parameter application method by using a biasing element that automatically applies and maintains optimal compression force on the cable seal. This eliminates the need for operators to judge and control compression parameters manually through screwing, thereby reducing installation errors while ensuring consistent sealing performance.
2Reliability
If a screwing mechanism is used to compress cable seals, then sealing can be achieved, but installation time increases and operator mistakes may occur
Solution Approach 1:
The patent incorporates a biasing element that is pre-loaded to automatically apply compression force to the cable seal upon assembly. This preliminary action eliminates the need for time-consuming manual screwing operations and ensures that the seal is immediately compressed to the correct force, preventing operator mistakes and reducing installation time while maintaining sealing reliability.
3Ease of operation
If individual cable entry segments are used, then accessibility of each cable port is improved, but the structure becomes more complex
Solution Approach 1:
The patent divides the end cap into multiple individual cable entry segments, each with its own sealing and compression mechanism. This segmentation allows each cable port to be accessed and sealed independently, improving ease of operation and accessibility. The modular segmented structure manages complexity by creating standardized, interchangeable units that simplify overall system assembly and maintenance.
