Flexible Fast Door for Cargo Housing Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing transportation housings face challenges in maintaining constant atmospheric conditions and preventing unauthorized access during loading and unloading, as rigid doors are cumbersome to operate and often remain open, exposing sensitive goods to environmental changes and security risks.
Innovation Solution
A housing with a motorized flexible fast door system that includes a flexible shutter with guiding rails, allowing for rapid and secure sealing and unsealing of the access opening, using a motorized driving mechanism to move the flexible shutter and integrating sensors for automatic operation based on presence detection or pre-set times.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a rigid door is used to seal the opening, then security and structural integrity are improved, but the door becomes cumbersome to open and close, leading to extended opening times and frequent remaining open during loading/unloading
Solution Approach 1:
The door system is divided into two distinct parts: a rigid door for security and structural integrity, and a flexible fast door for rapid sealing. Each component serves its specific function, allowing the rigid door to remain secure while the flexible fast door provides quick access control.
Solution Approach 2:
The flexible fast door acts as an intermediary element between the rigid door and the opening. It provides rapid sealing capability without compromising the security function of the rigid door, effectively mediating between security requirements and operational efficiency.
2Ease of operation
If the rigid door remains open during loading/unloading operations, then ease of operation is improved, but environmental conditions deteriorate and unauthorized access becomes possible
Solution Approach 1:
The door system is divided into two distinct parts: a rigid door for security and structural integrity, and a flexible fast door for rapid sealing. Each component serves its specific function, allowing the rigid door to remain secure while the flexible fast door provides quick access control.
Solution Approach 2:
The flexible fast door acts as an intermediary element between the rigid door and the opening. It provides rapid sealing capability without compromising the security function of the rigid door, effectively mediating between security requirements and operational efficiency.
3Reliability
If the rigid door is made more secure and robust, then reliability is improved, but the door becomes even more cumbersome to operate
Solution Approach 1:
The door system is divided into two distinct parts: a rigid door for security and structural integrity, and a flexible fast door for rapid sealing. Each component serves its specific function, allowing the rigid door to remain secure while the flexible fast door provides quick access control.
Solution Approach 2:
The flexible fast door acts as an intermediary element between the rigid door and the opening. It provides rapid sealing capability without compromising the security function of the rigid door, effectively mediating between security requirements and operational efficiency.
