Solution Overview

Problem

Conventional weatherproofing systems for coaxial cable connectors in harsh outdoor environments fail to provide a reliable seal over irregular surfaces and lack tactile feedback for proper installation, leading to weather-induced degradation and increased maintenance costs.

Innovation Solution

A protective system comprising an over-mold cap and a compliant Weather Protecting boot with a mating interface that provides tactile feedback during assembly, ensuring correct installation and a secure seal over the coaxial cable connector.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a soft silicone boot/sleeve is used to cover and protect the cable connection, then weather protection is improved, but the device complexity and difficulty of installation increase due to irregular surfaces and lack of installation feedback

Engineering Contradiction:
Improveweather protectionVSAvoidinstallation complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent incorporates a tactile feedback mechanism through a ribbed or fluted surface structure on the silicone boot. As the boot is stretched over the connector during installation, these ribs provide distinct tactile sensations that guide the installer through the installation process and confirm when proper installation has been achieved, thereby reducing installation complexity while maintaining weather protection reliability

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The silicone boot is divided into multiple functional zones: a tapered leading end for insertion, a mid-section with ribs or flutes for tactile feedback, and a sealed distal end for weather protection. This segmentation allows each portion to perform its specific function optimally while simplifying the overall installation process

Inventive Principle:
Principle #1Segmentation

2Reliability

If a large boot is used to slide over the connection to produce a seal, then weather sealing is improved, but the ease of operation deteriorates due to difficulty in manipulating over irregular surfaces

Engineering Contradiction:
Improveseal reliabilityVSAvoidease of installation
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The boot is pre-formed with a tapered leading end that facilitates initial insertion over the connector. This preliminary shaping of the boot's opening makes it easier to start the installation process over irregular connector surfaces, while the boot's compliance allows it to conform to the connector's shape as installation progresses

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The boot utilizes material compliance and elastic deformation parameters to adapt to irregular connector surfaces. The silicone material's ability to stretch and conform during installation, then maintain its sealed configuration once installed, resolves the contradiction between seal reliability and ease of operation

Inventive Principle:
Principle #35Parameter changes
