Rotating Plate Tyrolean Carriage for Line Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Tyrolean traverse carriages lack versatility and often require disconnecting the main line from its anchorages to install or remove the carriage, limiting their application and efficiency.
Innovation Solution
A carriage design featuring rotating front and rear plates with sheaves that transition between operative and open configurations, allowing the main line to be installed without disconnection, and incorporating locating means to secure the plates during operation, enabling easy installation and removal while maintaining load stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the carriage is designed with fixed plates to maintain structural integrity, then load-carrying capacity is improved, but ease of installation is worsened as the main line must be disconnected from anchorages
Solution Approach 1:
The carriage employs dynamically reconfigurable plates that can transition between closed and open configurations. The plates are connected via rotating joints allowing them to pivot between positions, enabling the carriage to adapt its structure during installation and operation phases
2Reliability
If the carriage uses a closed configuration with plates to constrain the line, then reliability is improved, but ease of operation is worsened as the carriage cannot be easily installed or removed
Solution Approach 1:
The carriage transitions from a static closed structure to a dynamic system where plates can pivot between closed and open configurations. This allows the carriage to be easily installed by opening the plates, then securely constrain the line when closed
Solution Approach 2:
The carriage structure is segmented into separate plates that can move independently relative to each other. This segmentation allows the plates to be opened for installation while maintaining the overall structural integrity when closed
3Ease of operation
If the carriage is designed to be easily installed by opening plates, then ease of operation is improved, but structural integrity is worsened during the opening/closing transitions
Solution Approach 1:
The plates are designed with rotating joints that provide controlled movement during opening and closing transitions. This dynamic connection maintains structural integrity during reconfiguration while enabling easy installation
Solution Approach 2:
The plates are pre-positioned and connected via rotating joints that guide their movement during opening and closing. This preliminary configuration ensures that the plates follow a predetermined path that maintains structural integrity during transitions
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The carriage provides enhanced versatility and ease of installation/removal, reducing load swinging and increasing operational efficiency by allowing the main line to be threaded through without disconnection, while maintaining structural integrity and load-carrying capacity.
Implementation Method 1
The carriage has a plurality of sheaves or other low-friction devices that allow it to travel along the main line
Implementation Method 2
transition between the open configuration and the operative configuration is achieved by mutual rotation of the front and rear plates about a rotation axis perpendicular to the plates

AI summary
A system and apparatus for moving objects is disclosed. The system includes a carriage for lifting and/or moving a load on one or more lines comprising at least two sheaves (30, 40) that are in, an operative configuration, disposed for rotation about a respective axis between front and rear plates (10, 12). The carriage has an open configuration in which at least one sheave is spaced from at least one of the front or rear plates. Transition between the open configuration and the operative configuration is achieved by mutual rotation of the front and rear plates (10, 12) about a rotation axis perpendicular to the plates that is coincident with the axis of rotation of one of the sheaves (30). In the apparatus, the carriage is carried, in the operative configuration, on a main line (60), whereby the carriage can travel on the main line supported by one or more sheave (30, 40).
