Solution Overview

Problem

Conventional housing locking devices for control cabinets and server cabinets require external forces to achieve tight closure due to limited closing forces, leading to inefficiencies and potential user interference with locking mechanisms.

Innovation Solution

A housing design featuring a door lock with two or three rotating locking elements connected via rigid coupling elements, allowing for high closing forces and enabling a display device to cover most of the door surface, while ensuring user safety by positioning locking elements vertically and avoiding protrusions that could cause obstruction.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Force

If a conventional locking device with a single locking element is used, then the device complexity is low, but the closing force is limited and external force is required to achieve tight closure

Engineering Contradiction:
Improveclosing forceVSAvoidlocking device complexity
Core Design Contradiction:
ForceVSDevice complexity

Solution Approach 1:

The locking device is segmented into multiple independent locking elements (at least two) that are spaced apart from each other. Each locking element can be rotated independently about its fastening element, allowing the closing force to be distributed across multiple engagement points, thereby achieving high closing force without requiring excessive complexity in a single locking mechanism

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Multiple locking elements are combined with rigid coupling elements that mechanically connect them. This merging allows the locking elements to move simultaneously and in unison, ensuring that all locking elements engage or disengage together, which maintains synchronization while achieving cumulative locking force

Inventive Principle:
Principle #5Merging (Combining)

2Area of moving object

If the locking device is integrated into the door element, then the ease of operation is improved, but the display device surface area is reduced due to space occupied by locking components

Engineering Contradiction:
Improvedisplay device surface areaVSAvoiddoor element integration
Core Design Contradiction:
Area of moving objectVSEase of operation

Solution Approach 1:

The locking elements are extracted from the door element and repositioned on the cladding element. This extraction removes the locking mechanism components from the door element surface, freeing up space for the display device to occupy a larger area, while the locking function remains integrated into the overall housing structure

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The locking elements are arranged in a vertical dimension on the cladding element rather than being distributed across the door element surface. This dimensional repositioning allows the display device to cover the door element surface while the locking elements are positioned in a different spatial plane, eliminating the trade-off between display area and locking functionality

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Reliability

If locking elements are positioned to achieve high closing force, then the reliability of locking is improved, but user safety is compromised due to potential entanglement with protruding locking elements

Engineering Contradiction:
Improvelocking reliabilityVSAvoiduser entanglement hazard
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

Instead of having locking elements protrude outward from the door element toward the user, the locking elements are inverted and positioned on the cladding element. This reversal of positioning ensures that the locking elements do not protrude into the user's space, eliminating the entanglement hazard while maintaining their locking function through proper engagement with the door element's locking mechanism

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