Interlocking Cargo Side Panels for Secure Side Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle cargo containers face security and operational challenges, with curtain sided trailers being vulnerable to intrusions and hazardous to open in high winds, while box trailers restrict side loading/unloading.
Innovation Solution
An interlocking panel apparatus for vehicle cargo containers that allows side-access by deploying panels in a fore-aft direction, featuring a plug-socket system for secure interlocking and easy retraction, using a single force input for combined release and retraction, and incorporating a runner system for smooth movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If curtain sided trailers are used to enable side loading/unloading, then ease of operation is improved, but security is worsened due to vulnerability to intrusions
Solution Approach 1:
The side panel is divided into multiple segments including a fixed panel and a movable panel that can be independently controlled. The movable panel can be opened for loading/unloading while the fixed panel remains closed to maintain security, allowing selective access rather than opening the entire side structure.
Solution Approach 2:
The panel system transitions from a static closed structure to a dynamic system where the movable panel can be opened and closed as needed. This dynamic capability allows the side structure to adapt between secure closed state and accessible open state, resolving the contradiction between security and ease of operation.
2Reliability
If box trailers with rigid side panels are used to improve security, then reliability is improved, but ease of operation is worsened by restricting side loading/unloading
Solution Approach 1:
The rigid side structure is segmented into fixed and movable panels, allowing the majority of the side (fixed panel) to remain secure and rigid while a portion (movable panel) provides loading access. This maintains the security benefits of rigid construction while adding operational flexibility.
Solution Approach 2:
The side structure incorporates a movable panel that transforms the otherwise static rigid structure into a dynamic system capable of opening and closing, enabling side loading/unloading while maintaining security when closed.
3Ease of operation
If curtains are opened and closed frequently for loading/unloading, then ease of operation is improved, but harmful factors increase due to hazards in high winds from tensioning straps and anchoring poles
Solution Approach 1:
The side structure is divided into fixed and movable panels that provide a controlled opening mechanism. This segmented approach allows loading access without requiring the entire side structure to be opened, reducing the surface area exposed to wind and minimizing the hazards associated with large canvas curtains billowing in gusts.
