Innovation Solution
A temperature control system integrated into the lid of the transit container, comprising a temperature control assembly, shock isolation devices, exhaust assemblies, and a mounting plate, which allows for airflow and inertial load transmission, maintaining a controlled temperature while minimizing the system's height to fit within the container's lid cavity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a temperature control system is integrated into the lid of the transit container, then the temperature control capability is improved, but the device complexity increases
Solution Approach 1:
The temperature control assembly is integrated into the lid structure of the transit container, merging the temperature control function with the existing container structure. This reduces the need for separate temperature control units and simplifies the overall system architecture while maintaining effective temperature regulation capability.
Solution Approach 2:
The lid structure is designed to serve multiple functions: it provides structural closure for the container while simultaneously housing the temperature control assembly. This multi-functionality reduces the number of separate components needed, thereby reducing device complexity while improving temperature control capability.
2Reliability
If shock isolation devices are used to protect the temperature control assembly, then the reliability is improved, but the device complexity increases
Solution Approach 1:
Shock isolation devices are pre-installed between the temperature control assembly and the lid structure to provide protective cushioning before shocks occur. This beforehand protection ensures the temperature control assembly is safeguarded against vibrations and shocks during transit, improving reliability without requiring complex active protection systems.
3Volume of moving object
If the temperature control assembly is located in a cavity of the lid, then the space utilization is improved, but the manufacturing precision requirements increase
Solution Approach 1:
The lid structure is segmented to create a dedicated cavity that houses the temperature control assembly. This segmentation allows the temperature control system to be precisely positioned within the lid volume, optimizing space utilization while the modular cavity design helps manage manufacturing precision requirements through standardized fabrication processes.

AI summary
A transit container, such as a rack-mount style container, includes a temperature control system for maintaining a desired temperature within the container such that any cargo within the container remains operational at selected times and possibly in selected locations. The temperature control system includes support or mounting brackets, a temperature control assembly, shock isolation devices for shock attenuation of the temperature control assembly, exhaust assemblies that include exhaust fans and exhaust/intake louvers, and a mounting plate attachable to a lid of the transit container. The temperature control assembly and the aforementioned components may be arranged to have a low-height profile or envelope, which in turn permits the temperature control system to be located in a cavity or chamber of the lid.
