Solution Overview

Problem

Current fastening systems for ventilation channels are laborious to install, prone to thread damage, and expose contamination-sensitive surfaces, requiring extensive manual effort and frequent cleaning due to their design and materials.

Innovation Solution

A fastening method using adaptable vertical fastening with double-sided and one-sided threaded pipes, featuring inner threads of the same direction, a retaining bolt, and a screw-in space for easy assembly and adjustment, reducing contamination risk with a smooth outer surface and minimizing exposed thread areas.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If threaded rods are used for fastening channels, then the fastening system can be assembled, but the installation becomes laborious and time-consuming due to cutting, thread damage, and manual adjustment

Engineering Contradiction:

Improveinstallation speedVSAvoidinstallation time

Core Design Contradiction:

ProductivityVSLoss of time

Solution Approach 1:

The threaded rod is segmented into two separate components: a first threaded component (rod) and a second threaded component (nut/sleeve). This segmentation allows each component to be optimized independently and assembled through a simple screwing operation, eliminating the need for cutting and manual adjustment while maintaining fastening functionality.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The threaded components are pre-assembled in a controlled manufacturing environment with precise thread engagement. This preliminary action ensures proper thread alignment and eliminates field cutting operations, allowing installers to simply screw the pre-assembled components into place without time-consuming adjustments.

Inventive Principle:

Principle #10Preliminary action

2Ease of manufacture

If threaded rods with exposed surfaces are used, then fastening is achieved, but contamination-sensitive surfaces collect dirt and dust requiring constant cleaning

Engineering Contradiction:

Improvefastening system simplicityVSAvoidcontamination

Core Design Contradiction:

Ease of manufactureVSObject-affected harmful factors

Solution Approach 1:

The second threaded component (nut or sleeve) is designed to enclose and protect the first threaded component (rod). This nesting arrangement shields the contamination-sensitive threaded surfaces from direct exposure to the environment, preventing accumulation of dirt and dust while maintaining the fastening function.

Inventive Principle:

Principle #7Nested doll (Nesting)

Solution Approach 2:

The second threaded component acts as a protective shell or cover that encloses the first threaded component. This shell structure provides a barrier against contamination while allowing the threaded connection to function, effectively reducing the exposed contamination-sensitive surface area.

Inventive Principle:

Principle #30Flexible shells and thin films

3Manufacturing precision

If threaded rods are cut to length at installation, then the correct length is achieved, but the thread is damaged requiring post-processing

Engineering Contradiction:

Improvelength accuracyVSAvoidthread integrity

Core Design Contradiction:

Manufacturing precisionVSReliability

Solution Approach 1:

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

Inventive Principle:

Principle #1Segmentation

4Adaptability or versatility

If tension locks with contrary thread directions are used, then distance adjustment is possible, but manual rotation in one direction is required consuming great effort

Engineering Contradiction:

Improvedistance adjustabilityVSAvoidadjustment effort

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

Instead of using contrary thread directions that require unwinding and rewinding, the invention uses threads of the same direction on both components. This inversion of the traditional tension lock design allows adjustment by simply screwing or unscrewing in one continuous direction, dramatically reducing the effort required for distance adjustment.

Inventive Principle:

Principle #13The other way round (Inversion)

AI summary

A fastening method of a channel with a vertical fastening, having a vertical anchor, a threaded pipe with a first and a second inner thread adjacent to a first and a second pipe opening, the first inner thread of which fits on a threaded connector of the vertical anchor and the inner threads arranged at a distance to each other. The vertical fastening also has a retaining bolt with a free thread end which fits into the second inner thread and a head end connectable or connected with a holding construction of the channel. The method includes fastening the top vertical anchor with the fastening end in a supporting horizontal construction, connecting the threaded connector with the first inner thread, screwing-in the free thread end into the second inner thread so that the holding construction of the channel is connected with the vertical anchor by the threaded pipe.
