Solution Overview

Problem

Existing electronic bays are complex to set up and maintain, and there is a risk of damage to connectors due to the large size and weight of drawers, which can lead to poor contact or connector damage during insertion.

Innovation Solution

The connectors are connected to the drawer by moving the panel, reducing the forces required to move the drawer and minimizing the risk of damage, with a system of tie rods and centering devices ensuring precise alignment and connection.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If the drawer is made large to accommodate multiple electronic modules, then the storage capacity is improved, but the drawer becomes heavy and difficult to handle, increasing the risk of connector damage during insertion

Engineering Contradiction:
Improvenumber of electronic modulesVSAvoiddrawer weight
Core Design Contradiction:
Quantity of substanceVSWeight of moving object

Solution Approach 1:

The system is divided into a stationary drawer and a movable panel. The drawer remains fixed in the support structure, while only the panel moves to establish connector connections. This segmentation eliminates the need to move the entire heavy drawer, reducing the risk of connector damage during insertion while maintaining the ability to accommodate multiple electronic modules.

Inventive Principle:
Principle #1Segmentation

2Quantity of substance

If the drawer is made large to accommodate multiple electronic modules, then the storage capacity is improved, but the complexity of setup and maintenance increases

Engineering Contradiction:
Improvenumber of electronic modulesVSAvoidsetup and maintenance complexity
Core Design Contradiction:
Quantity of substanceVSDevice complexity

Solution Approach 1:

By separating the drawer from the panel, the system simplifies maintenance operations. The panel can be independently moved and serviced without requiring the entire drawer assembly to be manipulated. This reduces setup and maintenance complexity while preserving the drawer's capacity to hold multiple electronic modules.

Inventive Principle:
Principle #1Segmentation

3Ease of operation

If clearance is provided between the drawer and support to facilitate easy insertion, then the ease of operation is improved, but the space utilization is reduced

Engineering Contradiction:
Improvedrawer insertion easeVSAvoidspace utilization
Core Design Contradiction:
Ease of operationVSVolume of moving object

Solution Approach 1:

Instead of moving the drawer relative to the support (conventional approach), the panel moves relative to the stationary drawer. This inversion allows the drawer to be firmly seated in the support with minimal clearance, maximizing space utilization while the movable panel provides the necessary movement for connector connection.

Inventive Principle:
Principle #13The other way round (Inversion)
