Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical signal connectors for coaxial cables require complex and labor-intensive installation procedures, which can lead to poor signal transmission quality if not properly aligned and secured.
Innovation Solution
A deformable cylindrical casing with a slidably engaged barrel that radially compresses the casing to securely fix the coaxial cable, eliminating the need for a compression tool at the cable entry end and simplifying the installation process across various connector types.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a compression tool is used at the cable entry end to compress the outer tubular member, then the connection stability is enhanced, but the installation procedure becomes complex and labor-intensive
Solution Approach 1:
The connector is designed to perform the compression function automatically during the insertion process. The barrel structure with its tapered inner surface and the deformable portion of the cylindrical casing work together to compress the outer tubular member and secure the cable without requiring an external compression tool, making the system self-servicing during installation
Solution Approach 2:
The barrel is pre-configured with a tapered inner surface that corresponds to the deformable portion of the cylindrical casing. This preliminary configuration ensures that when the cable is inserted, the compression action occurs automatically at the correct position and with the correct force distribution, eliminating the need for separate compression steps
2Reliability
If the end-cap is moved relative to the outer tubular member to compress it, then the cable is secured, but the outer tubular member may be biased relative to the cable and the barbed portion may not be positively forced into engagement
Solution Approach 1:
The compression function is localized to a specific deformable portion of the cylindrical casing that is positioned at the cable entry end. This deformable portion is specifically designed with material properties and geometric features that enable controlled radial compression, ensuring that the compression force is applied precisely where needed without affecting other parts of the connector
Solution Approach 2:
The barrel features a tapered inner surface and the deformable portion of the cylindrical casing has a curved geometry that facilitates radial compression. The curved surfaces guide the compression force uniformly around the cable, ensuring even engagement of the barbed portion with the cable shielding without creating stress concentrations or misalignment
3Ease of operation
If the coaxial cable is inserted through the end-cap before the outer tubular member, then the cable can be positioned, but the installation procedure requires much effort and time
Solution Approach 1:
The connector is segmented into distinct functional zones: the barrel with tapered surface for compression, the deformable portion of the cylindrical casing for cable securing, and the end-cap for final positioning. This segmentation allows each component to perform its function independently and simultaneously during a single insertion motion, eliminating multi-step procedures
Solution Approach 2:
The insertion, positioning, and securing functions are merged into a single operational sequence. The cable insertion through the barrel and deformable casing simultaneously achieves alignment and compression, while the end-cap movement integrates both positioning and final securing actions, reducing the installation to one continuous motion
