Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If conventional vacuum insulation systems are used, then thermal insulation performance is improved, but investment costs and manufacturing complexity increase significantly
Solution Approach 1:
The insulation system uses the transported cold medium itself to generate and maintain the vacuum in the insulation layer, eliminating the need for external vacuum pumps and complex vacuum generation equipment. The cold medium's temperature causes phase change of the volatile substance, creating vacuum automatically during normal operation.
Solution Approach 2:
The system utilizes phase transition of a volatile substance (from liquid to gas) driven by the cold medium's temperature to generate vacuum. The volatile substance evaporates when exposed to the cold medium, displacing air and creating vacuum conditions in the insulation layer without mechanical pumping.
2Loss of energy
If conventional vacuum insulation systems are used, then thermal insulation performance is improved, but flexibility and adaptability to complex geometries deteriorate
Solution Approach 1:
The system uses a flexible membrane to enclose the insulation layer containing the volatile substance. This membrane can be easily shaped and adapted to complex geometries of pipes, vessels, or structures, allowing the vacuum insulation to conform to any form while maintaining its insulating performance.
Solution Approach 2:
The volatile substance is pre-loaded into the insulation layer during manufacturing, ready to generate vacuum automatically when exposed to the cold medium during installation and operation, eliminating the need for post-installation vacuum pumping.
3Loss of energy
If mechanical pumping is used to create vacuum, then vacuum insulation performance is achieved, but production time and energy consumption increase
Solution Approach 1:
The system eliminates the need for external vacuum pumps by using the cold medium's own temperature to drive phase change of the volatile substance, which automatically generates and maintains the vacuum during normal operational conditions.
Solution Approach 2:
The volatile substance undergoes phase transition from liquid to gas when exposed to the cold medium's low temperature, creating vacuum conditions automatically without requiring mechanical pumping or prolonged evacuation time.
