Removable device for transporting equipment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing material transport devices, such as flight cases, often have non-removable bottoms or lids, leading to inefficient use of space when empty, and are difficult to repair if damaged, as well as complicating access to stored materials, especially when multiple layers of material are involved.
Innovation Solution
A removable material transport device with reversible securing means allowing frames to be disassembled and reassembled, featuring sectional doors and threaded inserts for easy assembly and disassembly, providing improved rigidity, cohesion, and impact resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the base and lid have non-removable walls (frame and plate riveted together), then the structural strength and integrity are improved, but the device cannot be disassembled for efficient empty transport and cannot be repaired by replacing individual walls
Solution Approach 1:
The transport device is divided into separable components: the base, lid, and side walls can be disassembled from each other. Each wall consists of a frame and plate that can be connected or separated, allowing the device to be configured as fully assembled or disassembled into individual components for efficient transport.
Solution Approach 2:
The connection between frame and plate is made dynamic rather than fixed. Threaded inserts allow the plate to be securely fastened to the frame during use, but can be easily unscrewed to separate components when disassembly is needed, providing both strength during operation and flexibility for transport.
2Strength
If the base and lid have non-removable walls, then the structural strength is improved, but the ease of repair deteriorates as damaged walls cannot be replaced
Solution Approach 1:
Each wall is segmented into separate frame and plate components that can be independently replaced. If a plate is damaged, only that specific plate needs to be unscrewed and replaced, while the frame and other components remain intact, dramatically simplifying repair compared to replacing entire non-removable walls.
Solution Approach 2:
The design allows individual damaged plates to be discarded and replaced while recovering and reusing the intact frames and other components. The threaded insert system enables quick removal of damaged plates and attachment of replacement plates without affecting the overall structural integrity of the device.
3Object-affected harmful factors
If the transport device is designed as a complete non-removable structure, then the protection of material is improved, but the volume efficiency when empty deteriorates
Solution Approach 1:
The device is segmented into separate base, lid, and wall components that can be disassembled. When the transport device is empty or not in use, components can be removed from the base, reducing the occupied volume significantly while maintaining full protection capabilities when assembled and needed.
Solution Approach 2:
The transport device transitions from a static fixed structure to a dynamic reconfigurable system. During transport operations, the device is fully assembled to provide maximum protection. When empty, components can be disassembled and removed, allowing the base to occupy minimal space, thus optimizing volume efficiency based on operational needs.
