Solution Overview

Problem

Existing cable connection devices, such as patch panels, require complex installation processes and limited accessibility for connecting installation cables to network cables, especially when already mounted in server cabinets or top-hat rails, making it difficult to easily mount and connect cables without disassembling the device.

Innovation Solution

A connecting device with a hinge mechanism that forms a pivot axis, allowing the base body to pivot relative to the support body, enabling easy access and connection of installation cables without removing the device from the support, featuring a film hinge and positive locking devices for secure attachment, and a plate-shaped connection field with recesses for RJ45 plugs and strain relief areas for installation cables.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the connecting device is mounted in a server cabinet or top-hat rail, then the device is securely fixed and stable, but the rear side becomes inaccessible for connecting installation cables

Engineering Contradiction:
Improveaccessibility to rear side for cable connectionVSAvoidsecure mounting position
Core Design Contradiction:
Ease of operationVSStability of the object's composition

Solution Approach 1:

The base body is made dynamically pivotable relative to the support body through the hinge mechanism. The hinge allows the base body to rotate between a first position (retracted, providing accessibility) and a second position (extended, providing stability during cable connection). This dynamic positioning resolves the contradiction by allowing the structure to adapt its configuration based on operational needs.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The connecting device is segmented into two main parts: the support body (mounted on the rail) and the base body (carrying the connection panel). The hinge mechanism separates these parts while maintaining their functional relationship, allowing independent positioning of each part to optimize both accessibility and stability during different phases of operation.

Inventive Principle:
Principle #1Segmentation

2Ease of manufacture

If the base body is rigidly fixed to the support body, then the connection is stable and secure, but the installation process becomes complex and time-consuming

Engineering Contradiction:
Improveinstallation simplicityVSAvoidtime for cable connection
Core Design Contradiction:
Ease of manufactureVSLoss of time

Solution Approach 1:

The hinge mechanism enables the base body to pivot dynamically during installation. Installers can first mount the support body on the rail, then attach the base body in a convenient position, and finally pivot it into its operational position. This dynamic attachment process is much simpler and faster than rigid fixation, reducing both installation complexity and time.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The hinge mechanism allows preliminary mounting of the base body in an accessible position for easy cable connection, followed by pivoting to the final stable position. This preliminary action enables installers to complete cable connections more efficiently before securing the final position.

Inventive Principle:
Principle #10Preliminary action

3Ease of operation

If the base body is made pivotable for easy access, then cable connection becomes simple, but the connection stability may be compromised

Engineering Contradiction:
Improvecable connection accessibilityVSAvoidconnection stability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The hinge provides controlled pivotability that maintains connection stability. The hinge axis is positioned and designed to allow rotation only in the intended direction and degree, ensuring that cable connections remain secure during the pivoting motion and in the final position. The mechanical design of the hinge ensures that stability is maintained while enabling the necessary movement for accessibility.

Inventive Principle:
Principle #15Dynamics
