Solution Overview

Problem

Large chassis mounting frames with a drawer-like fixing mechanism often experience instability due to a gap between connectors when the fixing frame is tilted, leading to an unstable connection.

Innovation Solution

The chassis mounting frame incorporates a rotating member and pivoting members connected to a coupling member, which moves in conjunction with the frame body, ensuring even distribution of force and preventing gaps between connectors by resisting structures, thus stabilizing the connection process.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If a handle is provided only on one side of the fixing frame for connection, then the device complexity is reduced, but the connection stability deteriorates due to gap formation when the fixing frame is tilted

Engineering Contradiction:
Improvehandle configurationVSAvoidconnection stability
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The connection mechanism is divided into two independent handles positioned on opposite sides of the fixing frame. Each handle independently controls a connector, allowing separate adjustment and connection on both sides. This segmentation eliminates the gap formation issue while maintaining reasonable device complexity through modular design

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent positions handles asymmetrically on opposite sides of the fixing frame rather than concentrating both on one side. This asymmetric distribution allows the fixing frame to be tilted and connected stably on both sides simultaneously, preventing gap formation while maintaining operational simplicity

Inventive Principle:
Principle #4Asymmetry

2Ease of operation

If the fixing frame is made tiltable for accessibility, then the ease of operation is improved, but the connection stability deteriorates due to gap formation between connectors

Engineering Contradiction:
Improvefixing frame accessibilityVSAvoidconnector connection stability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The fixing frame is designed with dynamic tilting capability allowing it to be tilted forward or backward for operational accessibility. Combined with independent handles on both sides, the frame can be tilted while maintaining stable connector connections through separate handle control, achieving both ease of operation and connection stability

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The connection system is segmented into independent left and right connector-handle pairs. This allows the fixing frame to be tilted for accessibility while each connector maintains stable connection through its dedicated handle, preventing gap formation even during tilting operations

Inventive Principle:
Principle #1Segmentation

AI summary

A chassis mounting frame includes a frame body, a fixing plate, a coupling member, a rotating member, and a pivoting member. The fixing plate is mounted on a side of the frame body and includes a resisting structure. The rotating member is provided on the frame body and coupled to the coupling member and configured to drive the coupling member to move inside the frame body and drive the coupling member and the frame body to move together. The pivoting member is provided on a side of the frame body and coupled to the coupling member. The coupling member is configured to drive the pivoting member to rotate to resist against the resisting structure.
