Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a sealing process is performed to seal the coupling portion of each member, then the vacuum space is formed, but small process errors lead to vacuum breakage and reduced reliability
Solution Approach 1:
The patent employs a flexible sealing structure where the sealing member can elastically deform to accommodate dimensional variations and misalignments during assembly. This elastic deformation capability allows the sealing member to maintain reliable sealing contact even when there are small process errors in the coupling portions, preventing vacuum breakage without requiring extremely high manufacturing precision.
2Reliability
If a radiation resistance sheet is added to resist radiation heat transfer, then adiabatic performance is improved, but device complexity increases
Solution Approach 1:
The patent combines multiple functions into the sealing member: it provides both sealing functionality to maintain the vacuum space and radiation resistance to block thermal radiation. By integrating the radiation resistance function directly into the sealing member through material selection or coating, the patent avoids adding a separate radiation resistance sheet, thereby maintaining adiabatic performance while minimizing structural complexity.
3Duration of action of stationary object
If the vacuum space is maintained for a longer duration, then adiabatic effect is sustained, but sealing reliability must be improved to prevent vacuum breakage
Solution Approach 1:
The patent designs the sealing member with built-in compensation capabilities that anticipate and cushion against potential sealing failures over time. The elastic deformation capability and dimensional tolerance accommodation are designed beforehand to prevent vacuum breakage during extended operation, allowing the vacuum adiabatic body to maintain its vacuum state for longer durations without compromising sealing reliability.
