Solution Overview

Problem

Existing locking arrangements face challenges in achieving stability and easy installation of slide rails due to the large space requirements, which complicates the integration and maintenance of additional elements within the housing.

Innovation Solution

The housing incorporates an additional element that protrudes into the locking arrangement, providing stability and allowing for the indirect coverage of the slide rail, enabling the connection of further elements without impairing the sliding mechanism and allowing for easy assembly and maintenance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If the housing is designed to cover the slide rail, then the stability of the housing is improved, but the space required for the slide rail makes it difficult to provide sufficient stability

Engineering Contradiction:
Improvehousing stabilityVSAvoidspace required by slide rail
Core Design Contradiction:
Stability of the object's compositionVSVolume of moving object

Solution Approach 1:

The patent introduces a third dimension by adding a protruding element that extends into the interior space of the locking arrangement. This dimensional addition allows the housing to achieve stability without increasing the overall footprint, as the protruding element utilizes previously unused internal volume to provide structural support and mounting surfaces.

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

Solution Approach 2:

The protruding element is nested within the housing structure, extending into the interior space rather than adding external bulk. This nested configuration allows the housing to maintain its compact form while incorporating additional stabilizing features that would otherwise require separate components or increased overall dimensions.

Inventive Principle:
Principle #7Nested doll (Nesting)

2Reliability

If the housing covers the slide rail, then protection is improved, but integration and maintenance of additional elements within the housing becomes complicated

Engineering Contradiction:
Improveprotection of slide railVSAvoidintegration and maintenance of additional elements
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The protruding element serves as an intermediary structure between the housing and additional elements. It provides dedicated mounting surfaces and attachment points that simplify the integration of further components, acting as a mediator that reduces the complexity of connecting multiple elements within the confined housing space.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The housing is segmented into functional zones by the protruding element, which creates distinct mounting areas and spatial divisions. This segmentation allows additional elements to be independently positioned and maintained without interfering with the slide rail or other components, reducing overall system complexity.

Inventive Principle:
Principle #1Segmentation

3Stability of the object's composition

If additional components are added to increase stability, then housing stability is improved, but device complexity increases

Engineering Contradiction:
Improvehousing stabilityVSAvoidnumber of components
Core Design Contradiction:
Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The patent merges the stabilizing function with the existing housing structure by incorporating the protruding element as an integrated feature rather than a separate component. This consolidation achieves enhanced stability without increasing the number of discrete parts, as the protruding element becomes an inherent part of the housing assembly.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The protruding element performs multiple functions: it provides structural stability, creates mounting surfaces for additional elements, and defines spatial zones within the housing. This multi-functionality eliminates the need for separate components dedicated to each function, reducing overall device complexity while achieving multiple objectives.

Inventive Principle:
Principle #6Universality (Multi-functionality)
