Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The assembly of threaded coupling connectors for coaxial cables is difficult due to the need for strong finger pressure to achieve rotational movement and axial thrust, which can lead to unsafe and inefficient coupling.
Innovation Solution
A connector design featuring formations by way of fins on the outer body to support finger rotation and an annular projection for linear advance, minimizing finger pressure required for assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If threaded coupling is used to connect the connector to the coaxial cable, then mechanical retention and electrical connection are achieved, but strong finger pressure is required making assembly difficult
Solution Approach 1:
The patent introduces an annular projection that extends radially outward from the body, creating a new dimensional element for finger engagement. This radial extension provides an additional leverage point perpendicular to the original axial pressing direction, allowing users to apply rotational force more effectively without increasing axial pressure on the cable.
Solution Approach 2:
The annular projection acts as an intermediary element between the user's fingers and the connector body. It transfers and amplifies the rotational force applied by the user, mediating the interaction between manual operation and the threaded coupling mechanism, thereby reducing the direct pressure required on the cable assembly.
2Device complexity
If the outer cover of the coaxial cable is used for threading, then no additional components are needed, but the lack of consistency in the outer cover requires strong pressure to achieve linear advance
Solution Approach 1:
By extending the body radially outward to form an annular projection, the patent creates a new dimensional interface for force application. This radial extension allows users to leverage their fingers more effectively, converting lateral finger pressure into rotational motion without requiring excessive axial force on the cable's outer cover.
Solution Approach 2:
The patent segments the force application interface by separating the rotational engagement (through the annular projection) from the linear advancement (through the threaded inner cover engagement). This segmentation allows each function to be optimized independently, reducing the overall force required for assembly.
3Ease of operation
If rough configuration on the outer surface is provided for finger engagement, then tool-free assembly is enabled, but insufficient leverage is provided making assembly difficult
Solution Approach 1:
The annular projection extends the finger engagement surface radially outward, providing significantly increased leverage arm length. This dimensional extension transforms the rough surface from a mere grip area into a powerful torque-generating interface, enabling tool-free assembly while eliminating the harmful effect of assembly difficulty.
Solution Approach 2:
The rough configuration on the annular projection is preliminarily designed to optimize finger grip and rotational force application. By pre-configuring the surface texture and geometry, the patent prepares the interface for effective manual operation, ensuring that users can easily initiate and complete the threading action without tools.
