Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The assembly and disassembly of mobile amusement rides with towers typically require heavy machinery and significant manpower, especially for high towers, which is inefficient and labor-intensive.
Innovation Solution
A method involving the sequential assembly and disassembly of tower sections using a winch system and pneumatic or hydraulic rams mounted on a transportable former, allowing for the construction of towers without the need for heavy cranes, with prefabricated sections that can be nested for transport and easily connected and disconnected.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If heavy cranes and heavy plant are used to erect and disassemble high towers, then the tower can be assembled and disassembled, but the process requires considerable manpower and heavy machinery
Solution Approach 1:
The tower is divided into multiple sections that can be assembled and disassembled independently. Each section can be handled by smaller lifting equipment rather than requiring a single heavy crane to move the entire tower structure, thereby reducing the complexity and weight of required assembly equipment.
Solution Approach 2:
Tower sections are designed to nest within each other during transport and storage. The smaller sections fit inside larger sections, creating a compact configuration that reduces transport requirements and simplifies the assembly process by pre-organizing components in a space-efficient manner.
2Productivity
If heavy cranes are used to erect high towers, then the tower can be constructed to great height, but the process is labor-intensive and inefficient
Solution Approach 1:
Tower sections are pre-assembled and pre-positioned in a nested configuration before the actual tower erection begins. This preliminary preparation work is done on the ground where it is safer and more efficient, reducing the time required during the actual tower assembly operation and improving overall productivity.
Solution Approach 2:
A former structure serves as an intermediary framework that guides and supports the assembly of tower sections. This former acts as a temporary mediator that holds sections in correct position during assembly, eliminating the need for complex positioning operations and heavy equipment, thereby reducing assembly time and improving efficiency.
3Length of moving object
If the tower is constructed as a single high structure, then riders can enjoy great height, but disassembly requires heavy plant and considerable manpower
Solution Approach 1:
The high tower is segmented into multiple manageable sections that can be disconnected and removed sequentially. This segmentation transforms the disassembly process from moving an entire heavy structure to handling individual lighter sections, making disassembly easier and requiring less heavy equipment.
Solution Approach 2:
The tower structure is designed with dynamic characteristics that allow sections to be easily connected and disconnected. The modular design with standardized connection points enables the tower to transition between assembled and disassembled states efficiently, improving ease of operation during disassembly while maintaining the required height when assembled.

AI summary
A tower is constructed by erecting an upright former (6); assembling a first section (31) of the tower around the former (6); raising the first tower section (31); assembling a second tower section (32) around the former (6); connecting the first and second tower sections (31, 32), and repeating the steps to add further tower sections. Disassembly is the reverse process. The method of assembly is particularly suitable to mobile towers that are transported on road trailers and may be used with advantage with amusement rides.
