Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional transport refrigeration systems, especially those powered by fuel cells, face lengthy and expensive repair times, leading to on-road time losses and potential losses of perishable goods due to complex and integrated systems.
Innovation Solution
The transport refrigeration system is designed with modular components, including a fuel cell system, allowing for quick replacement and maintenance of parts such as the compressor, heat exchanger, and power distribution systems, utilizing mechanical and electrical interfaces for easy installation and disconnection, thereby reducing downtime.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If the transport refrigeration system uses a conventional integrated design, then the system structure is simple, but the repair time is lengthy and the system downtime is increased
Solution Approach 1:
The transport refrigeration system is divided into multiple independent modular units, each containing specific components (compressor, condenser, evaporator, control system). These modules can be independently removed and replaced without affecting the entire system, enabling rapid repair and reducing downtime while maintaining overall system functionality through the remaining modules.
2Loss of time
If the transport refrigeration system uses modular components, then the repair time is reduced and downtime is minimized, but the device complexity increases
Solution Approach 1:
The modular components are designed with standardized interfaces and mounting mechanisms that can be applied across different refrigeration system configurations. The control system modules can manage multiple types of components, and the standardized electrical and mechanical connections allow the same module design to serve various functions, reducing the overall complexity despite the modular architecture.
