Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If cooling vents are designed with fixed closures, then the structural integrity and protection of the HV cable is improved, but the ability to cool the cable effectively is worsened
Solution Approach 1:
The venting closures are designed to be movable rather than fixed, allowing them to transition between open and closed positions. This dynamic design enables the system to provide both protection when closed and cooling when open, resolving the contradiction between structural integrity and cooling effectiveness.
2Temperature
If cooling channels are permanently open, then the cooling effectiveness is improved, but the protection and safety of the electrical systems is worsened
Solution Approach 1:
The movable venting closures enable the cooling channels to be dynamically opened or closed based on operational requirements. This allows the system to maintain safety by closing the channels when protection is needed while preserving cooling capability when opened, resolving the contradiction between cooling effectiveness and system safety.
3Reliability
If the fuselage structure is sealed, then the protection against environmental factors is improved, but the accessibility for maintenance is worsened
Solution Approach 1:
The fuselage structure is segmented with movable venting closures that can be independently opened to provide access to the battery pack and HV cable. This segmentation allows the majority of the fuselage to remain sealed for protection while specific sections can be opened for maintenance, resolving the contradiction between environmental protection and maintenance accessibility.
