Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a ring is inserted into the heat exchange pipeline to space it from the plate, then adiabatic performance is improved, but the installation becomes extremely difficult and the ring may move from desired position
Solution Approach 1:
The spacing function is divided into multiple discrete spacing members positioned at different locations around the heat exchange pipeline, rather than using a single continuous ring. This segmentation makes installation easier while maintaining adiabatic performance
Solution Approach 2:
The spacing members are designed to be installed before the heat exchange pipeline is placed, allowing for easier positioning and fixation. The supporting unit is prepared in advance to guide and secure the pipeline at the correct position
2Strength
If the ring is made of solid material to support the plate, then structural strength is improved, but heat conduction increases causing adiabatic loss
Solution Approach 1:
The supporting unit uses a lattice structure with localized solid members rather than a continuous solid ring. This provides structural strength at specific points while maintaining thermal insulation through the open lattice structure
Solution Approach 2:
The supporting unit combines materials with different thermal properties, using low thermal conductivity materials for the spacing members while maintaining mechanical strength through the structural design
3Reliability
If foam filling material is added to provide adiabatic walls, then adiabatic performance is improved, but fabrication cost increases and fabrication method becomes complicated
Solution Approach 1:
The patent removes the foam filling material and separate adiabatic wall structure, relying instead on the vacuum adiabatic body and strategically positioned spacing members to achieve the required thermal insulation
Solution Approach 2:
The supporting unit and spacing function are merged into a single integrated structure, eliminating the need for separate adiabatic materials and simplifying the fabrication process
