Solution Overview

Problem

Existing wall supports for electrical conductor carrier trays face issues with installation means, structural resistance, insulation, humidity retention, and lack of installation restrictions.

Innovation Solution

A redesigned wall support featuring a rectangular seat base with an inverted 'U' shaped section, including tilted slide holes for electrical insulation conduits, reinforced ribs, and tilted surfaces to facilitate drainage, along with the removal of transverse end stop flanges to prevent water accumulation and enhance structural integrity.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If traditional wall supports are used with basic installation means, then the structure is simple, but the structural resistance and installation efficiency are insufficient

Engineering Contradiction:
Improvestructural resistanceVSAvoidstructure complexity
Core Design Contradiction:
StrengthVSDevice complexity

Solution Approach 1:

The wall support is divided into distinct functional segments: the seat base for mounting, the inverted U-shaped section for tray support, reinforcement ribs for structural strength, and drainage features for humidity management. Each segment performs a specific function, allowing the overall structure to achieve high structural resistance through modular design rather than monolithic complexity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The design incorporates three-dimensional reinforcement elements including vertical reinforcement ribs extending from the seat base, transverse partitions within the U-shaped section, and tilted drainage surfaces. These multi-dimensional structural additions enhance structural resistance by distributing loads across multiple spatial dimensions rather than relying on a single plane.

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

2Object-affected harmful factors

If conventional wall supports are used, then the design is simple, but humidity retention and water accumulation occur

Engineering Contradiction:
Improvehumidity retentionVSAvoiddesign complexity
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The design extracts and removes water accumulation zones by eliminating transverse end stop flanges that would trap moisture. Instead, open transverse partitions are used that allow water to drain through, actively removing the harmful humidity retention effect from the structure.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

Rather than using horizontal surfaces that promote water accumulation, the design inverts the approach by incorporating tilted drainage surfaces and sloped partitions that actively direct water away from critical areas. The drainage holes in the seat base invert the traditional solid mounting surface into a permeable, draining structure.

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

3Productivity

If traditional installation means are used, then the installation process is straightforward, but installation efficiency and adaptability are limited

Engineering Contradiction:
Improveinstallation efficiencyVSAvoidinstallation means complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The seat base is designed with multiple functions: it serves as the mounting interface to the wall, provides structural reinforcement through integrated ribs, enables drainage through tilted surfaces and holes, and supports the inverted U-shaped section. This multi-functionality increases installation efficiency by combining multiple operations into a single component rather than requiring separate installation steps for each function.

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

Solution Approach 2:

The reinforcement ribs and drainage features are pre-formed as integral parts of the seat base during manufacturing, rather than requiring field installation. The tilted drainage surfaces and reinforcement structures are built-in beforehand, allowing for faster on-site installation without requiring additional construction steps.

Inventive Principle:
Principle #10Preliminary action

4Reliability

If basic wall support design is used, then manufacturing is simple, but electrical insulation and structural integrity are compromised

Engineering Contradiction:
Improveelectrical insulationVSAvoidmanufacturing complexity
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The wall support employs composite construction combining electrically insulating materials for the seat base and U-shaped section with conductive reinforcement ribs. This composite approach provides electrical insulation where needed while maintaining structural integrity through the reinforcement elements, achieving both reliability and manufacturability through material differentiation.

Inventive Principle:
Principle #40Composite materials

AI summary

Wall support for electrical conductors trays, formed by a rectangular seat base (21), for sitting on a vertical wall, from which there emerges in cantilever arrangement an inverted "U" shaped section (22) the branches (23) of which are perpendicular to the base thereof (24) and which decrease in height. Base (24) of the inverted "U" shaped section forms a flat seating spine (25) for the trays. Seat base (21) is provided with slide through holes (26). Each branch (23) of the inverted "U" shaped section has, in the top part of the connection with seat base (21), a slide hole (37) that forms an outlet for a transverse electrical insulation conduit that crosses the gap of the inverted "U" shaped section (22).
