Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing theatrical barrier retraction systems are not portable, lack flexibility in line length adjustment, and are cumbersome to assemble and disassemble, leading to uneven presentations and time-consuming setup.
Innovation Solution
A portable barrier retraction system featuring a rotatable shaft with a detachable second drum and spools that allows for independent length adjustment and quick assembly/disassembly, enabling easy transport and replacement of components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If manual drawing of strings or cables from a central location is used, then the system is simple in structure, but the system is not portable and is cumbersome to erect
Solution Approach 1:
The system is divided into multiple modular components including separate drums, support frames, and line spools that can be independently assembled and disassembled. Each drum can be mounted on its own support frame, allowing the system to be segmented into transportable units that can be easily erected and dismantled without requiring complex centralized structures.
2Device complexity
If fixed-length strings or cables are used in known systems, then the system structure is simplified, but flexibility in measuring line lengths is lost resulting in uneven presentation
Solution Approach 1:
The line length is made dynamically adjustable through individual line spools that can be independently rotated to extend or retract lines as needed. Each spool allows for continuous adjustment of line length to achieve precise measurement and even presentation across different barrier configurations, transforming the fixed-length constraint into a flexible, adaptable system.
3Device complexity
If integrated drum components are used, then the system structure is simplified, but replacement of malfunctioning components becomes time-consuming
Solution Approach 1:
The drum assembly is segmented into separable components including the drum body, support frame, and line spool that can be independently removed and replaced. This modular segmentation allows malfunctioning components to be quickly swapped out without requiring disassembly of the entire drum mechanism, significantly reducing repair time while maintaining overall system structural integrity.
4Device complexity
If non-detachable components are used, then the system structure is simplified, but portability and transport capability are reduced
Solution Approach 1:
All major components including drums, support frames, and line spools are designed with detachable connections that allow the system to be broken down into compact, transportable modules. These segmented components can be easily assembled at the deployment location and disassembled for transport, achieving high portability without requiring complex integrated structures.
