Solution Overview

Problem

In rack-mounted electronic devices, the varying depths of electronic devices make it difficult to align and connect wiring on the back faces, as the positions of the back faces differ due to different device dimensions.

Innovation Solution

The design includes a pair of first and second columns with rails and movable fixing pieces that allow electronic devices of different depths to be aligned by adjusting the position of the fixing pieces, enabling the back faces to be aligned for easier wiring connection.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If electronic devices with different depths are mounted in the rack, then the rack can accommodate diverse electronic devices, but the back faces of the devices are positioned at different heights making wiring connection difficult

Engineering Contradiction:
Improveability to accommodate electronic devices with different depthsVSAvoidease of wiring connection
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The fixing piece is designed to be movable between a front position and a rear position, allowing dynamic adjustment of the electronic device's position along the depth direction. This enables the back face of shorter devices to be aligned with the back face of taller devices, facilitating uniform wiring connection while maintaining the ability to accommodate various device depths

Inventive Principle:
Principle #15Dynamics

2Device complexity

If a fixed positioning structure is used for electronic devices in the rack, then device positioning is simple, but devices with different depths cannot be properly aligned for wiring

Engineering Contradiction:
Improvesimplicity of positioning structureVSAvoidalignment precision of back faces
Core Design Contradiction:
Device complexityVSManufacturing precision

Solution Approach 1:

The fixing piece can be positioned at different locations along the depth direction and fixed at each position. This allows the structure to maintain simplicity while achieving precise alignment of back faces for wiring, as the fixing piece can be adjusted to compensate for depth differences between devices

Inventive Principle:
Principle #15Dynamics

AI summary

An electronic device storage rack is equipped with a pair of first columns provided at intervals in a width direction; a pair of second columns provided at intervals in the width direction at positions away from the pair of first columns on a back side; a plurality of pairs of rails which connect the first column and the second column to support the electronic device main body to be slidable in a depth direction; a first fixing piece which is movable between an abutment position capable of abutting on the first column from the front side on the front side of the electronic device main body and a non-abutment position disposed between the first columns; and a second fixing piece which is movable between the abutment position capable of abutting on the second column from the back side on the back side of the electronic device main body and the non-abutment position disposed between the second columns.
