Portable environmental control units for temporary shelters face size and weight restrictions that limit their capacity and efficiency for cooling and heating, necessitating a solution that enhances performance while minimizing transport footprint.
Innovation Solution
An expandable environmental control unit with a base section and a mobile section that can be collapsed for storage and transport, featuring a temperature control system with a compressor, outdoor heat exchangers, and an indoor heat exchanger, which can be expanded to provide efficient air flow and temperature control, utilizing a reversing valve for heating or cooling functions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If the environmental control unit is designed with fixed compact dimensions for transport, then it meets size and weight restrictions, but its cooling and heating capacity is limited
Solution Approach 1:
The environmental control unit employs an expandable mobile section that can transition between a collapsed configuration for transport and an extended configuration for operation. The mobile section includes extendable struts and movable components that allow the unit to dynamically change its dimensions, enabling it to meet size restrictions during transport while providing sufficient cooling and heating capacity when deployed in the extended position.
2Area of stationary object
If the environmental control unit is designed with fixed compact dimensions for transport, then it meets size restrictions, but its efficiency is limited
Solution Approach 1:
The unit utilizes an expandable mobile section with extendable struts and movable heat exchangers that allow the system to optimize its surface area and heat transfer efficiency when deployed. The outdoor and indoor heat exchangers can extend to provide adequate heat transfer area for efficient operation, while retracting to minimize footprint during transport.
3Productivity
If the mobile section is extended for operation, then capacity and efficiency are improved, but the footprint for transport increases
Solution Approach 1:
The mobile section is designed to nest within or collapse against the base section when not in use. The extendable struts and movable heat exchangers can be retracted into a compact configuration that fits within the base section's footprint, allowing the unit to be transported in a minimized volume while maintaining full capacity when deployed.
