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

VSEngineering 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

Engineering Contradiction:
Improverepair timeVSAvoidsystem structure
Core Design Contradiction:
Ease of repairVSDevice complexity

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.

Inventive Principle:
Principle #1Segmentation

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

Engineering Contradiction:

Core Design Contradiction:
Loss of timeVSDevice complexity

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.

Inventive Principle:
Principle #6Universality (Multi-functionality)
