Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing maritime chutes for evacuation have complex designs that complicate manufacturing, assembly, disassembly, and maintenance, making them cumbersome and difficult to service.
Innovation Solution
A maritime chute design featuring alternating first and second sections with distinct connection means, ensuring correct alignment and assembly through opposing indications, and a helix slide path with overlapping helix parts and zippers for easy assembly and disassembly, along with a chute dispenser for storage and deployment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a complex design is used to fulfill safety requirements and varying heights, then the reliability and adaptability are improved, but the device complexity and ease of manufacture increase
Solution Approach 1:
The chute is divided into multiple modular sections that can be connected in series to achieve the required length and provide easy assembly/disassembly while maintaining safety standards
Solution Approach 2:
The connection means are designed to provide multiple functions: mechanical connection, alignment guidance through indications, and locking capability, reducing the need for separate components
2Reliability
If a complex design with multiple components is used, then the reliability is improved, but the ease of repair and ease of operation worsen
Solution Approach 1:
The modular section design allows individual sections to be replaced or serviced without affecting the entire chute system, facilitating maintenance while maintaining overall safety
Solution Approach 2:
The connection means with integrated indications and locking mechanisms are designed to be self-aligning and self-latching, reducing the need for complex servicing procedures
3Reliability
If traditional connection methods are used, then the reliability may be maintained, but the productivity and ease of operation decrease
Solution Approach 1:
The indications are pre-positioned on the sections to guide alignment before connection, and the locking mechanisms are pre-configured to engage automatically, speeding up assembly while ensuring secure connections
Solution Approach 2:
The connection system replaces complex mechanical alignment procedures with visual indications and geometric constraints, allowing faster assembly by operators
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
Facilitates easy assembly, disassembly, and maintenance of the chute, reducing the risk of assembly errors and enabling efficient service without disrupting the system's integrity.
Implementation Method 1
The elastic cords and rings are arranged to allow longitudinal stretching as well as contraction. Due to the elastic cords, the chute is able to stretch as well as contract to compensate for varying height caused by waves.
Implementation Method 2
The stocking-like device is adapted to slow a rate of descent of a falling person who is being evacuated through the stocking-like device.
