Solution Overview

Problem

Existing device installation sockets for cable ducts require two separate types for vertical and horizontal installations, leading to cumbersome designs with unnecessary walls that obstruct cabling and increase production and inventory costs.

Innovation Solution

A single, open-topped device installation box with a C, J, or U-like shape and a foldable fourth side wall that can pivot inward for easier access, allowing for both horizontal and vertical installations without additional assembly steps or parts.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If two separate types of installation boxes are used for vertical and horizontal installations, then the installation requirements for different orientations are met, but the device complexity and inventory requirements increase

Engineering Contradiction:
Improveinstallation orientation adaptabilityVSAvoidnumber of box types
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The installation box is designed with a foldable fourth side wall that can be positioned in different configurations to accommodate both vertical and horizontal installations, allowing a single box type to serve multiple installation orientations and eliminating the need for separate box types

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

Solution Approach 2:

The fourth side wall is designed to be foldable rather than fixed, allowing it to dynamically change position between vertical and horizontal orientations during installation, enabling the same box to adapt to different installation requirements

Inventive Principle:
Principle #15Dynamics

2Stability of the object's composition

If unnecessary walls or web structures are included in the installation box, then the box structure is complete for all orientations, but the fitter's access to the inside of the box is obstructed

Engineering Contradiction:
Improvebox structure completenessVSAvoidfitter access
Core Design Contradiction:
Stability of the object's compositionVSEase of operation

Solution Approach 1:

The fourth side wall is designed as a foldable component that can be moved out of the way during installation to provide unobstructed access for the fitter, then positioned back to complete the box structure after installation is finished

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The fourth side wall is separated as a distinct foldable component rather than being permanently integrated, allowing it to be independently positioned to balance structural completeness with installation accessibility

Inventive Principle:
Principle #1Segmentation

3Reliability

If multiple types of installation boxes are maintained in inventory, then the appropriate box type is available for each specific installation, but production and inventory costs increase

Engineering Contradiction:
Improveinstallation suitabilityVSAvoidinventory variety
Core Design Contradiction:
ReliabilityVSQuantity of substance

Solution Approach 1:

A single installation box design with a foldable fourth side wall can fulfill both vertical and horizontal installation requirements, eliminating the need to maintain separate inventory types and reducing production costs while ensuring installation suitability

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

AI summary

The present invention relates to a device mounting box for cable ducts, essentially comprising: - an open-topped housing (1) with a base (2) and three side walls (3a, 3b, 3c) which together, viewed from above, have a C-, J- or U-shaped form and which each have means (4a, 4b, 4c) for attaching an electrical mounting device, - at least one, preferably two, cable entry openings (5, 6), - and at least one retaining device (7) attached to the outside of the base (2) for attaching the housing (1) to the cable duct, characterized in that: - the fourth side wall (3d) is designed as a hinged bridge pivotably attached to the base (2) towards the interior of the housing (1), which has at least one means (4d) at its upper free end which can cooperate at least with the means (4b) located on the opposite side wall (3b) for said attachment when the bridge is folded vertically upwards from the base (2).
