Solution Overview

Problem

Existing attachment devices for telecom equipment on tubular elements require multiple screws of varying lengths, making assembly cumbersome and prone to errors, especially when dealing with varying tube diameters, and often result in lost nuts.

Innovation Solution

An attachment device featuring a wavelike geometry spacer element with stiffening sections and a galvanized barrel nut with a distally located section of internal threads, allowing a single screw length to fit various diameters, and chamfered planes to prevent rotation, facilitating easy assembly and secure mounting.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple screws of varying lengths are used to attach the device to tubes of different diameters, then the attachment device can be adapted to different tube sizes, but the assembly process becomes cumbersome and error-prone

Engineering Contradiction:

Improveadaptability to different tube diametersVSAvoidassembly process simplicity

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The attachment device employs a universal screw of fixed length that can be used across multiple tube diameters. The single screw design replaces the need for multiple screws of varying lengths, allowing the same screw to function for attaching the device to tubes of different sizes through the adjustable clamp mechanism.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The clamp mechanism incorporates dynamic adjustment capabilities that allow the attachment device to adapt to different tube diameters. The adjustable components enable the same screw to secure the device to tubes of varying sizes by modifying the clamp's configuration rather than changing the screw itself.

Inventive Principle:

Principle #15Dynamics

2Adaptability or versatility

If the attachment device is designed to fit various tube diameters, then versatility is improved, but the device complexity increases

Engineering Contradiction:

Improverange of tube diameters accommodatedVSAvoidnumber of components

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The attachment device uses a single universal screw that serves multiple functions across different tube diameters. This eliminates the need for multiple specialized screws, reducing the number of components while maintaining the ability to attach to various tube sizes through the adjustable clamp mechanism.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The invention combines the functions of multiple screws into a single screw system. By merging the adaptation capability into the clamp mechanism rather than requiring different screws for different diameters, the device reduces component count while achieving the same versatility.

Inventive Principle:

Principle #5Merging (Combining)

3Adaptability or versatility

If screws are made long enough to accommodate larger diameter tubes, then larger tubes can be attached, but the screws project and interfere with the equipment mounting

Engineering Contradiction:

Improvecapability to attach to larger diameter tubesVSAvoidscrew projection interference

Core Design Contradiction:

Adaptability or versatilityVSObject-generated harmful factors

Solution Approach 1:

The clamp mechanism dynamically adjusts its configuration based on tube diameter, allowing the use of a fixed-length screw for both small and large diameter tubes. For larger tubes, the adjustable clamp compensates for the increased diameter without requiring a longer screw, thereby preventing screw projection and interference with equipment mounting.

Inventive Principle:

Principle #15Dynamics

4Ease of manufacture

If the attachment device uses a fixed design for a specific tube diameter, then manufacturing is simplified, but adaptability to other diameters is lost

Engineering Contradiction:

Improvemanufacturing simplicityVSAvoidrange of applicable tube diameters

Core Design Contradiction:

Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The attachment device is segmented into modular components, with the clamp mechanism designed as an adjustable module that can accommodate different tube diameters. This segmentation allows the base structure to be manufactured simply while the adjustable clamp provides the versatility to fit various tube sizes.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The clamp mechanism incorporates dynamic adjustment features that allow a single manufactured design to adapt to different tube diameters. The adjustable components enable the same manufactured device to be configured for various tube sizes without requiring multiple specialized manufacturing runs.

Inventive Principle:

Principle #15Dynamics
