Solution Overview

Problem

Existing SPIE rigs require time-consuming and costly manual work to replace or insert attachment devices into braided ropes, as the rope must be unbraided to access damaged or additional anchor points.

Innovation Solution

A modular attachment device comprising braiding segments and lateral fixation segments that can be inserted or removed without unbraiding the rope, utilizing a modular design with secure form-fit connections for easy replacement and adaptation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of repair

If the braided rope is opened to replace or insert attachment devices, then the attachment devices can be accessed and replaced, but the process becomes time-consuming and cost-intensive

Engineering Contradiction:
ImproveEase of replacing attachment devicesVSAvoidTime required to open and close braided rope
Core Design Contradiction:
Ease of repairVSLoss of time

Solution Approach 1:

The attachment device is divided into modular components: a rigid body with anchor points, a first braiding segment for insertion into the rope strands, and a second braiding segment for closing. This segmentation allows the device to be inserted and closed without opening the entire braided rope structure, enabling rapid replacement while maintaining rope integrity.

Inventive Principle:
Principle #1Segmentation

2Ease of repair

If the braided rope is opened to access attachment devices, then replacement is possible, but manual work and costs increase

Engineering Contradiction:
ImproveEase of inserting additional attachment devicesVSAvoidManual work required for rope manipulation
Core Design Contradiction:
Ease of repairVSEase of manufacture

Solution Approach 1:

The attachment device comprises separable modular components including a rigid body and two distinct braiding segments. This allows the device to be inserted into the braided rope without manipulating or opening the rope itself, significantly reducing manual work and making the process more cost-effective while enabling easy insertion of additional attachment devices.

Inventive Principle:
Principle #1Segmentation

3Device complexity

If a non-modular attachment device is used, then the structure is simpler, but replacement requires unbraiding the entire rope

Engineering Contradiction:
ImproveSimplicity of attachment device structureVSAvoidDifficulty of replacing attachment devices
Core Design Contradiction:
Device complexityVSEase of repair

Solution Approach 1:

The attachment device is segmented into a rigid body with anchor points and two braiding segments that interface with the rope strands. This modular structure maintains relative simplicity while enabling easy replacement through insertion and closing actions without requiring unbraiding of the entire rope, thus improving ease of repair without excessive complexity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The braiding segments are designed to be flexible and adaptable, allowing the attachment device to be dynamically inserted into and closed within the braided rope structure. This dynamic capability enables the device to integrate with the rope while maintaining ease of replacement, balancing structural simplicity with repairability.

Inventive Principle:
Principle #15Dynamics
