Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional fastening methods are used to attach electrical installations to junction boxes, then the electrical installation can be secured, but the fastening process becomes complex and time-consuming

Engineering Contradiction:
Improvesecuring of electrical installationVSAvoidfastening method complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The support sections are segmented into discrete elements with specific geometric features (protrusions, recesses, claw receiving areas) that enable modular attachment of electrical installations. Each support section functions as an independent fastening unit, simplifying the overall attachment process while maintaining reliability

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The support sections are designed to automatically guide and secure the expanding claws through their geometric features (protrusions fitting into recesses, claw receiving areas). The structure performs the fastening function through its inherent design rather than requiring complex external fastening mechanisms, thereby simplifying the fastening process while ensuring reliable attachment

Inventive Principle:
Principle #25Self-service

2Ease of manufacture

If the tubular side wall has equal extent in all directions (circular cross-section), then the structure is simple, but insertion of electrical conduits becomes difficult when connected to another junction box

Engineering Contradiction:
Improvestructural simplicityVSAvoidconduit insertion ease
Core Design Contradiction:
Ease of manufactureVSEase of operation

Solution Approach 1:

The tubular side wall employs an asymmetric cross-sectional design (oval, rectangular, or polygonal) with greater extent in one direction than others. This asymmetry creates directional access channels that facilitate easy insertion of electrical conduits when the junction box is connected to another box, while maintaining structural simplicity through the regular geometric form

Inventive Principle:
Principle #4Asymmetry

Solution Approach 2:

The support sections extend laterally into the installation space, creating a third dimension of access beyond the simple tubular wall. This lateral extension provides additional pathways and space for conduit insertion from multiple directions, solving the access difficulty while maintaining the overall simplicity of the tubular structure

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

3Ease of operation

If the installation space is enlarged to facilitate component connection, then electronic components can be connected more easily, but the available space for inserting electrical conduits along the perimeter is reduced

Engineering Contradiction:
Improvecomponent connection easeVSAvoidconduit insertion space
Core Design Contradiction:
Ease of operationVSArea of stationary object

Solution Approach 1:

The support sections are segmented into discrete elements positioned at specific locations within the installation space. These segmented support structures organize the installation space efficiently, providing component mounting areas while preserving perimeter regions for conduit insertion, thus resolving the space allocation conflict

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The support sections provide localized functionality within the installation space, concentrating the component mounting function in specific areas while leaving other regions (particularly along the perimeter) available for conduit insertion. This local differentiation of function allows both component connection and conduit insertion to occur simultaneously without spatial conflict

Inventive Principle:
Principle #3Local quality

AI summary

The present invention relates to an electrical installation box (1) comprising a tubular side wall (2) extending in an axial direction and surrounding an installation space (3). The tubular side wall (2) surrounds an installation opening (5) at a first end (4) and, viewed from the axial direction, has a greater extension in a first direction than in a second direction perpendicular to the first direction. Furthermore, an inner surface (8) of the tubular side wall (2) facing the installation space (3) has two support sections (10) that are substantially opposite each other with respect to the first direction. These support sections project laterally into the installation space (3) and serve to support the clamping claws of an electrical installation arranged in the installation space (3) perpendicular to the support sections.
