Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vertical slider or dolly systems for camera and lighting equipment have limited functionality due to short vertical ranges of motion, restricting smooth vertical tracking movements in filmmaking and other industries.
Innovation Solution
The development of sturdy and durable pulley system assemblies with modular components that allow for demountable engagement, counterbalancing, and rail-rolling modules, enabling precise control and extended vertical movement of loads along a vertical path, along with transportable rolling movement on work sites.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If existing vertical slider or dolly systems are used, then the equipment can provide smooth movement along a track, but the vertical range of motion is limited to short distances
Solution Approach 1:
The system is divided into multiple modular components including pulley assemblies, cable components, and load support subassemblies that can be interconnected to achieve extended vertical ranges of motion while maintaining smooth controlled movement
Solution Approach 2:
The modular pulley system can be configured for multiple functions including vertical lifting, counterbalancing, and support for various equipment types (cameras, lights, microphones), replacing the limited functionality of existing vertical sliders
2Length of moving object
If a modular pulley system with multiple components is implemented, then the vertical range of motion is extended, but the device complexity increases
Solution Approach 1:
Standardized modular components with universal connection interfaces allow the system to achieve extended vertical range of motion while maintaining manageable complexity through component reuse and standardized assembly procedures

AI summary
A counterbalanced vertical track assembly which may be configured with three types of pulley support assemblies are herein disclosed. The first type of pulley support assembly has a pair of opposed pulley modules having an elongate structural element interposed the two pulley modules which are attached to end plates at both ends of the elongate structural element. The second type of pulley support assembly has a pair of opposed pulley modules which include male end connectors for demountable engagement of the pulley modules with another module of the system with female ends. The third type of pulley support assembly has a pair of opposed pulley modules wherein the modules' pulley brackets are repositionable to varying angular orientations by alternating screw mount positions selected on mount components at opposite ends of an elongate structural element.
