Solution Overview

Problem

Existing modular distribution frames are bulky, aesthetically unpleasing, and lack effective dust and moisture protection, making them difficult to mount and operate.

Innovation Solution

A closed modular distribution frame with a compact, metal structural body that is designed to be more aesthetically pleasing and functional, featuring a reduced thickness, sealed design, and modular components for easy mounting and operation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the distribution frame body is made thicker to improve durability and sealing, then the protective performance is improved, but the device occupies more space and increases transportation cost

Engineering Contradiction:
Improvesealing performanceVSAvoiddevice volume
Core Design Contradiction:
ReliabilityVSVolume of moving object

Solution Approach 1:

The patent employs metal structural materials with composite construction to achieve high strength and sealing performance in a compact form. The closed box body structure combined with metal material properties provides enhanced durability without increasing overall device volume, resolving the contradiction between reliability and space occupation.

Inventive Principle:
Principle #40Composite materials

2Volume of moving object

If the distribution frame body is made thinner to reduce space occupation and transportation cost, then the device volume is reduced, but the firmness and durability are compromised

Engineering Contradiction:
Improvedevice volumeVSAvoidfirmness
Core Design Contradiction:
Volume of moving objectVSStrength

Solution Approach 1:

The distribution frame is divided into modular components including upper cover, bottom shell, and side walls that can be assembled together. This segmentation allows for optimized thickness of individual parts while maintaining overall structural strength, enabling reduced device volume without sacrificing firmness.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Metal structural materials are used to provide high strength-to-weight ratio, allowing the distribution frame to be made thinner while maintaining adequate firmness and durability. The material properties compensate for reduced thickness.

Inventive Principle:
Principle #40Composite materials

3Ease of manufacture

If a semi-closed structure is used to simplify manufacturing, then the ease of manufacture is improved, but the dust prevention and moisture prevention capabilities are insufficient

Engineering Contradiction:
Improvemanufacturing simplicityVSAvoiddust and moisture penetration
Core Design Contradiction:
Ease of manufactureVSObject-affected harmful factors

Solution Approach 1:

The patent merges multiple protective functions into a unified closed box body structure. The complete enclosure integrates dust prevention, moisture prevention, and mechanical protection into a single design, achieving comprehensive protection without significantly complicating manufacturing through standardized closing mechanisms.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

The present application discloses a closed modular distribution frame, which includes a distribution frame body. The distribution frame body is a closed box body. The closed modular distribution frame further includes a grounding wire. The grounding wire is mounted inside the distribution frame body. At least two network wiring ports are provided in a sidewall of the box body. The height of the network wiring ports accounts for less than or equal to 58.3% of the height of the distribution frame body. Compared with the existing network distribution frame, the height of the network wiring ports in the present application is unchanged, the thickness is reduced, and the miniaturization design saves space, is more beautiful, and reduces the transportation cost. At the same time, the interior of the distribution frame body adopts modular design, thus facilitating the mounting. The whole distribution frame body is made of a metal structural material, is a closed box body and is closely connected through the fastening assemblies, thus achieving higher firmness and durability, having good sealing performance and dustproof performance, having a protective effect on the interior of the distribution frame body, and effectively increasing the service life of the product.
