Pipe-Batten Hoist Layout for Space-Constrained Stage Rigging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional hoist systems are bulky and inefficient, occupying valuable space in cramped environments and requiring costly custom designs, especially in theatrical or performance settings where they need to be adaptable and scalable.
Innovation Solution
A compact self-climbing hoist system with a motor-driven drum enclosed within a pipe batten, featuring a cable management system, overload sensors, slack-line detectors, and adjustable mechanisms for fine-tuning and scalability, allowing for efficient use of space and adaptable applications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If conventional hoist systems are used, then lifting function is provided, but space occupation is excessive and custom design costs increase
Solution Approach 1:
The hoist mechanism is nested within the pipe batten structure. The pipe batten serves as both the structural support element and the enclosure for the hoist components, with the drum and motor housed inside the pipe batten. This nesting eliminates the need for separate external enclosures and reduces overall space occupation while avoiding custom design requirements.
Solution Approach 2:
The pipe batten performs multiple functions: it serves as the structural support beam, the enclosure for the hoist mechanism, and the mounting structure for attachments. This multi-functionality consolidates multiple components into a single universal element, reducing space requirements and eliminating the need for custom-designed separate components.
2Power
If conventional hoist systems are used, then lifting capability is achieved, but torque requirements increase
Solution Approach 1:
The drum is positioned inside the pipe batten, allowing the cable to wrap around the drum in a compact configuration. This nested arrangement optimizes the cable path and reduces the lever arm distance, thereby reducing the torque required by the motor while maintaining full lifting capability within a smaller space.
3Volume of moving object
If compact design is implemented, then space occupation is reduced, but installation flexibility must be maintained
Solution Approach 1:
The pipe batten is designed as a universal component that can be installed in various locations and configurations. Its standardized design allows it to serve as both the structural support and the hoist enclosure, providing installation flexibility across different environments while maintaining a compact form factor.
Solution Approach 2:
The hoist system incorporates adjustable mechanisms that allow for fine-tuning of the cable length and positioning. This dynamic adjustability enables the compact hoist to adapt to different installation requirements and load positions, maintaining versatility despite the reduced size.

AI summary
A hoist system having a drum primarily self-contained within a batten, for raising and lowering lighting, sound equipment, curtains and the like in a performance environment. The hoist system may be adapted with safety mechanisms including an overload sensor and/or a slack line detector. The system may be provided in the form of a point hoist. The compact system is highly scalable to a variety of spaces and applications, including school and public theaters and concert halls, as well as some homes, private business, etc. Additional features include various cable management systems and trim adjustment mechanisms for use with the hoist system.
