Solution Overview

Problem

Existing cable and pipe support structures often rely on conventional bonding or bolting systems, which can be cumbersome and prone to functional issues when loaded with cables, pipes, or other components.

Innovation Solution

A support structure comprising parallel profiles made of composite material, connected by crossties with geometrically matching grooves and stop projections, allowing for secure mechanical engagement without the need for conventional bonding or bolting systems.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional bonding or bolting systems are used to connect profiles and crossties, then the structure can be assembled, but the assembly process becomes cumbersome and reliability decreases under load

Engineering Contradiction:
Improveoperational reliabilityVSAvoidassembly complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent replaces conventional bonding or bolting systems with a mechanical interlocking system featuring grooves and stop projections. The crossties have grooves that receive stop projections from the profiles, creating a secure connection through geometric matching rather than adhesives or fasteners. This substitution eliminates the complexity and reliability issues associated with conventional bonding or bolting methods.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The design implements a nested configuration where the stop projections are inserted into the grooves of the crossties. The profile's stop projection fits within the crosstie's groove, creating a nested interlocking mechanism that provides secure mechanical engagement while simplifying the assembly process.

Inventive Principle:
Principle #7Nested doll (Nesting)

2Ease of manufacture

If composite material is used for all components, then manufacturing ease and insulation capabilities improve, but structural strength may be compromised

Engineering Contradiction:
ImprovemanufacturabilityVSAvoidstructural strength
Core Design Contradiction:
Ease of manufactureVSStrength

Solution Approach 1:

The patent specifies that profiles and crossties are made of composite material, combining the benefits of ease of manufacture with adequate structural strength. The composite material allows for integral formation of complex geometries including grooves and stop projections, while the interlocking design ensures sufficient load-bearing capacity.

Inventive Principle:
Principle #40Composite materials

Solution Approach 2:

The grooves in the crossties are designed with curved bottoms rather than sharp corners. This curvature prevents stress concentration points that would compromise structural strength, while still maintaining the effectiveness of the mechanical interlocking system. The rounded geometry is particularly suitable for composite material manufacturing.

Inventive Principle:
Principle #14Spheroidality (Curvature)

3Reliability

If geometrically matching grooves and stop projections are used for connection, then mechanical engagement is secured without bonding or bolting, but manufacturing precision requirements increase

Engineering Contradiction:
Improvemechanical engagement reliabilityVSAvoidgroove and projection tolerance
Core Design Contradiction:
ReliabilityVSManufacturing precision

Solution Approach 1:

The patent employs specific dimensional parameters for the grooves and stop projections that optimize both mechanical engagement and manufacturing feasibility. The groove dimensions, projection sizes, and tolerances are carefully selected to ensure reliable interlocking while accommodating standard composite material manufacturing capabilities. The curved bottom of grooves and the specific geometry of stop projections are designed to balance precision requirements with manufacturability.

Inventive Principle:
Principle #35Parameter changes
