Refrigerator Box Ramp Assembly for Continuous Door Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing refrigerator box solutions do not allow for continuous use of a ramp while the refrigerator door is being opened and closed, requiring the ramp to be disengaged, which affects temperature control and efficiency.
Innovation Solution
A stand-alone, all-in-one refrigerator box with a built-in ramp that is moveable between a stowaway position and an angled position, allowing for loading and unloading without disengaging the ramp, even when the refrigerator door is opened and closed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a ramp is attached to the front of a container for loading and unloading, then the loading and unloading process is facilitated, but the ramp must be disengaged when the container doors are opened and closed, disrupting continuous operation
Solution Approach 1:
The ramp assembly is designed with dynamic movement capability, allowing it to transition between a loaded position (extending from the container front) and a stowed position (retracted into the container). This dynamic repositioning enables the ramp to be automatically moved out of the door path during opening/closing operations while remaining ready for immediate use during loading/unloading, eliminating the need for manual disengagement and reattachment
Solution Approach 2:
The ramp assembly is nested within the container structure, with the ramp capable of being retracted into a storage compartment or positioned within the container body when not in use. This nesting arrangement allows the ramp to be stored compactly within the container's internal volume, clearing the door path without requiring external storage space or manual removal
2Ease of operation
If the ramp is positioned for loading and unloading, then cargo access is improved, but the refrigerator door cannot be opened and closed without disengaging the ramp
Solution Approach 1:
The ramp assembly incorporates dynamic positioning mechanisms that allow it to be automatically repositioned based on the operational state of the container. When the door needs to open or close, the ramp dynamically transitions to a retracted or elevated position that clears the door path. When loading or unloading is required, the ramp dynamically extends to the appropriate angle and position, enabling both door operations and cargo access without compromise
Solution Approach 2:
The system performs preliminary action by automatically repositioning the ramp assembly before the door opening or closing operation begins. This preliminary repositioning ensures that the ramp is already clear of the door path when the door starts to move, preventing any interference. The ramp then returns to its loading position after the door operation is complete, maintaining continuous readiness for cargo operations
3Productivity
If the ramp remains engaged during door operations, then continuous loading support is maintained, but the door cannot be opened or closed
Solution Approach 1:
The ramp assembly is designed with automated dynamic movement capability that responds to door position sensors or control signals. When the door begins to open or close, the ramp automatically transitions to a retracted position that clears the door path, allowing uninterrupted door operation. The system then automatically returns the ramp to its loading support position once the door operation is complete, maintaining continuous productivity without manual intervention
Solution Approach 2:
The system maintains continuity of useful action by ensuring the ramp is continuously available for loading support during periods when it is not interfering with door operations. The automated repositioning and return mechanisms ensure that the ramp transitions smoothly between operational states without requiring manual disengagement or reattachment, thereby maintaining continuous productivity while enabling necessary door operations

AI summary
A stand-alone, all-in-one refrigerator box and, more particularly, to a refrigerator box that provides a built-in ramp that is moveable between a stowaway position and an angled position in connection with the refrigerator box for loading and unloading the refrigerator box without having to disengage the ramp while the refrigerator door is being opened and closed.
