Solution Overview

Problem

Existing HDMI plugs often interfere with adjacent connectors or device parts due to their design, leading to aesthetic issues and usability challenges, particularly when multiple interfaces are closely packed.

Innovation Solution

The HDMI plug features a rotatable insulation housing that allows the plug body to be rotated relative to the HDMI interface, eliminating interference without the need for additional cables, and is designed with a compact, integrated structure using gear meshing or belt convey connections for smooth operation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If the HDMI plug uses an integrated plastic case structure, then the manufacturing is simple and compact, but the plug body interferes with adjacent connectors or device parts

Engineering Contradiction:
Improveintegrated plastic case structureVSAvoidplug interference with adjacent parts
Core Design Contradiction:
Ease of manufactureVSObject-affected harmful factors

Solution Approach 1:

The plug body is divided into a fixed part and a rotatable part, allowing the plug to be segmented into different functional components that can move independently to avoid interference with adjacent parts

Inventive Principle:
Principle #1Segmentation

2Object-affected harmful factors

If additional cables are added to resolve interference, then plug interference is eliminated, but the appearance becomes ugly and convenience is reduced

Engineering Contradiction:
Improveplug interference resolutionVSAvoidappearance and convenience
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The plug incorporates a rotatable mechanism that allows dynamic adjustment of the plug body position, enabling the plug to adapt its orientation to avoid interference with adjacent parts while maintaining a clean integrated appearance

Inventive Principle:
Principle #15Dynamics

3Object-affected harmful factors

If the plug body is made larger to avoid interference, then interference with adjacent parts is reduced, but the compact form factor is lost

Engineering Contradiction:
Improveinterference reductionVSAvoidplug compactness
Core Design Contradiction:
Object-affected harmful factorsVSVolume of moving object

Solution Approach 1:

Rather than increasing size, the invention uses a rotatable mechanism that allows the existing compact plug body to dynamically change its orientation, effectively avoiding interference without increasing volume

Inventive Principle:
Principle #15Dynamics
