Solution Overview

Problem

Existing rope adjustment systems for suspending apparatus under a gantry require separate mechanisms for adjusting and locking the rope length, making operations complex and difficult, especially as they often necessitate loosening knots and sliding through multiple holes, and do not allow for subsequent length adjustments without disassembly.

Innovation Solution

A device comprising an adjustment box with wedging surfaces and a blocking strap that can pivot and lock the rope in place, allowing for both length adjustment and secure locking without the need for separate mechanisms, enabling easy assembly and disassembly of the blocking flange.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If separate adjustment and locking mechanisms are used, then the rope length can be adjusted and locked, but the device complexity increases and operations become complex

Engineering Contradiction:
Improvelocking reliabilityVSAvoiddevice complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines the adjustment function and locking function into a single integrated device. The adjustment box houses both the wedging surfaces for length adjustment and the blocking strap for locking, eliminating the need for separate mechanisms and simplifying the overall device structure while maintaining reliable locking capability

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The adjustment box serves multiple functions: it provides wedging surfaces for rope adjustment, houses the blocking strap mechanism, and enables both length modification and secure locking through a single device structure, making the system more versatile and less complex

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

2Adaptability or versatility

If knots and multiple holes are used for adjustment, then the rope length can be modified, but the ease of operation decreases

Engineering Contradiction:
Improveadjustment flexibilityVSAvoidease of operation
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent extracts the complex knot-tying and hole-sliding operations and replaces them with a simplified mechanism featuring a blocking strap that can be easily positioned and locked against wedging surfaces, maintaining adjustment flexibility while dramatically improving ease of operation

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The blocking strap is designed to be movable during adjustment, allowing it to be positioned at different locations along the rope length, and then becomes static when locked against the wedging surface, providing both flexibility and ease of operation

Inventive Principle:
Principle #15Dynamics

3Reliability

If the blocking flange is permanently assembled, then the locking is secure, but the adaptability for subsequent adjustments decreases

Engineering Contradiction:
Improvelocking securityVSAvoidreadjustment capability
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The device is segmented into removable components, specifically the blocking flange that can be detached from the adjustment box, allowing the system to maintain secure locking when assembled while enabling subsequent adjustments by disassembling and reassembling the components in different configurations

Inventive Principle:
Principle #1Segmentation
