Cable Car Control Tire Drive Isolation via Pivotable Rocker
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cable car systems experience vibrations and noise due to the transmission of hoisting rope vibrations to the support structure through pivotable rockers used to drive control tires, leading to adverse effects like noise emissions.
Innovation Solution
The support structure for control tires is designed with a pivotable rocker mounted on a crossbeam that is not attached to the main supporting structure, and additional beams are used to absorb vibrations, ensuring that the control tires' drive is decoupled from the rigid support, thereby minimizing vibrations and shocks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the support roller for the conveyor rope is mounted on a pivotable rocker to derive drive for control tires, then the drive transmission is improved, but vibrations and shocks are transmitted to the support frame causing noise emissions
Solution Approach 1:
The system is divided into two separate support structures: one support structure for mounting the pivotable rocker and support roller (isolated from vibrations), and another support frame for mounting the control tires. This segmentation prevents vibration transmission while maintaining drive functionality.
Solution Approach 2:
The pivotable rocker and support roller are extracted from the support frame and mounted on a separate support structure. This extraction removes the vibration source from the support frame, eliminating noise emissions while preserving the drive mechanism's operation.
2Stability of the object's composition
If the support roller is mounted rigidly to derive drive for control tires, then structural stability is improved, but vibrations and shocks are directly transmitted causing adverse effects
Solution Approach 1:
The system separates the rigid support structure (providing stability) from the support frame (mounting control tires). The pivotable rocker on the rigid structure provides drive while the separate support frame remains stable without vibration transmission.
Solution Approach 2:
The pivotable rocker acts as an intermediary between the rigid support structure and the control tires. It transmits drive force while its pivotable nature and separate mounting prevent direct vibration transmission to the support frame.
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
This configuration significantly reduces vibrations and noise emissions, providing a more stable and quiet operation by isolating the support structure from the hoisting rope's impacts and movements.
