Multimedia Socket Tapered Interface Design for Cable Strain Relief
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multimedia sockets face challenges in maximizing the use of available space, especially when accommodating multiple coaxial connectors, leading to cramped installations and potential strain on connection cables.
Innovation Solution
The multimedia socket design features interface bodies with a taper or undercut in the axial direction, allowing for a greater distance between opposing outer walls in the taper area, enabling more efficient use of space and reliable strain relief for connection cables, while maintaining adaptation of characteristic impedances through proportional tapering of inner and outer conductors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple coaxial connectors are accommodated in the multimedia socket, then the quantity of interfaces is increased, but the available space becomes cramped and connection cables are subjected to strain
Solution Approach 1:
The patent introduces a tapered axial dimension to interface bodies, creating a gradual expansion in the axial direction. This dimensional change allows connection cables to be routed through the taper area with sufficient clearance, preventing cable strain while maintaining a compact footprint on the face of the socket. The taper transforms a two-dimensional space constraint into a three-dimensional solution.
2Area of stationary object
If interface bodies are positioned close together to maximize space, then the area utilization is improved, but connection cables cannot be properly routed without strain
Solution Approach 1:
By adding the axial taper dimension, the patent resolves the conflict between compact area utilization and cable strain relief. The taper creates a gradual expansion zone that provides necessary cable clearance without increasing the face area occupied by interface bodies, thus maintaining high area utilization while ensuring reliable cable routing.
Solution Approach 2:
The patent changes the geometric parameters of interface bodies by introducing a taper angle and taper length. This parameter modification creates a transition zone that gradually increases the axial distance between opposing outer walls, providing sufficient space for cable routing while keeping the interface bodies positioned close together on the socket face.
3Area of stationary object
If interface bodies are positioned close together to maximize space, then the area utilization is improved, but the distance between opposing outer walls is insufficient for cable routing
Solution Approach 1:
The patent applies the taper along the axial direction of interface bodies, creating a gradual expansion in length along that dimension. This allows the distance between opposing outer walls to increase progressively from the base to the tip of the taper, providing sufficient clearance for cable routing while maintaining compact positioning of interface bodies on the socket face.

AI summary
The multimedia box (100) has four interfaces (130a-130d) among which two interfaces (130a,130b) are arranged in the region of input side (106) of connection cables. The tapered portions are formed over partial length of the respective interfaces (130a,130b) in the axial direction, and extended from front end of the respective interfaces to the main portion of housing (102). The distance between the opposing outer walls (136a,136b) of interfaces in the region of the tapered portions is greater than the distance between the outer walls of interfaces in the region of front end side.
