Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If conventional space travel experiments are conducted, then understanding of space effects on human biology is improved, but ability to decouple gravity effects from other factors is insufficient
Solution Approach 1:
The invention segments the complex space environment into distinct controllable components by using a space simulator that can independently vary gravity (through rotation), temperature, and other parameters. This allows researchers to study gravitational effects in isolation from other space-related stressors, directly addressing the limitation of conventional space travel experiments where multiple factors occur simultaneously.
2Measurement precision
If microfluidic Brain-On-Chip is used to simulate space conditions, then cellular-level assessment of space effects is enabled, but device complexity increases
Solution Approach 1:
The microfluidic Brain-On-Chip serves as an intermediary system between conventional space experiments and direct human subject studies. This chip-based platform allows precise control and measurement of cellular responses to space conditions, providing high measurement precision while avoiding the complexity of conducting full-scale human experiments in space. The chip acts as a simplified model that captures essential biological responses.
3Adaptability or versatility
If temperature control is added to simulate space conditions, then environmental accuracy is improved, but device complexity and operational requirements increase
Solution Approach 1:
The space simulator is designed with multi-functionality, where a single rotating platform system simultaneously achieves gravitational simulation through centrifugal force and temperature control through integrated environmental chambers. This universal design allows the same hardware infrastructure to serve multiple experimental needs, reducing overall system complexity compared to having separate dedicated systems for each function.
