Solution Overview
Problem
Existing collapsible building systems with foldable walls and retractable roofs require multiple steps and assistance to assemble and secure shelving platforms, and traditional solutions like tents and prefabricated warehouses lack stability and load-bearing capacity.
Innovation Solution
A sidewall system with a single-side eave mechanism that includes a gear rod, eave panel, and support rods, allowing automatic unfolding and folding of the eave panel with the sidewall, and a retractable roof with movable sections that span between sidewalls, providing improved stability and ease of assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If traditional portable walls are assembled with fixed shelving planes, then the structure provides stable support for equipment, but the assembly process requires multiple steps and assistance from others
Solution Approach 1:
The eave panel automatically deploys itself through the gear mechanism when the sidewall is opened, eliminating the need for manual assembly of the shelving plane. The system serves itself by converting the sidewall's opening motion into automatic eave panel deployment, requiring no additional assembly steps or assistance.
Solution Approach 2:
The gear mechanism is pre-configured on the sidewall before deployment. When the sidewall opens, the pre-positioned gear automatically engages with the eave panel, initiating the deployment sequence beforehand and eliminating the need for on-site assembly of the shelving structure.
2Strength
If fixed structures use heavy materials for stability, then the load-bearing capacity is sufficient, but the transportation weight increases significantly
Solution Approach 1:
The structure transitions from a static, heavy fixed form to a dynamic, lightweight deployable form. The aluminum alloy sidewall and eave panel maintain sufficient strength when deployed through their geometric configuration and mechanical support, while weighing significantly less than traditional fixed structures. The system only carries the minimum necessary weight during transportation when collapsed.
Solution Approach 2:
The structure uses lightweight aluminum alloy materials locally where needed for strength, rather than heavy materials throughout. The eave panel and sidewall use aluminum alloy specifically at load-bearing points, while maintaining overall lightweight construction for easy transportation.
3Weight of moving object
If tents use lightweight materials for portability, then the transportation weight is reduced, but the structure cannot withstand larger loads such as wind pressure and snow
Solution Approach 1:
The structure combines lightweight aluminum alloy materials with a robust mechanical gear mechanism to create a composite system that achieves both light weight and high strength. The aluminum alloy provides corrosion resistance and lightweight properties, while the gear mechanism and structural geometry provide the necessary load-bearing capacity to withstand wind and snow pressures.
4Strength
If prefabricated mini warehouses are designed for strength, then the load-bearing capacity is sufficient, but the structure becomes large and difficult to transport
Solution Approach 1:
The structure is divided into separable components (sidewall, eave panel, gear mechanism) that can be collapsed and stored in a compact form. When deployed, these segments assemble into a strong load-bearing structure. The segmentation allows the system to achieve full strength when needed while minimizing transportation volume when collapsed.
5Ease of operation
If the eave panel is manually assembled with the sidewall, then the shelving plane can be secured, but the installation of top devices becomes complex and time-consuming
Solution Approach 1:
The eave panel automatically deploys itself through the gear mechanism when the sidewall is opened, eliminating the need for manual assembly of the shelving plane. The system serves itself by converting the sidewall's opening motion into automatic eave panel deployment, requiring no additional assembly steps or assistance.
Solution Approach 2:
The deployment of the eave panel is continuous with the opening of the sidewall - as the sidewall opens, the gear mechanism continuously converts this motion into eave panel deployment. This continuous action eliminates interruptions and additional steps, reducing total assembly time.
