Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an object is moved in free fall on Earth to create zero gravity, then the effective gravity is reduced, but air resistance prevents the effective gravity from reaching close to zero
Solution Approach 1:
The system is divided into an external module that experiences air resistance during free fall and an internal module that maintains the experimental environment. This segmentation allows the external module to handle the harmful air resistance effect while the internal module preserves the zero gravity state for experiments.
Solution Approach 2:
The external module acts as an intermediary that shields the internal module from air resistance. By having the external module experience the atmospheric drag during free fall, the internal module is protected from direct exposure to this harmful factor, maintaining more accurate zero gravity conditions.
2Reliability
If complex and expensive equipment is used to create zero gravity or microgravity, then the gravity state can be achieved, but the device complexity and cost increase significantly
Solution Approach 1:
The invention extracts the essential function of creating zero gravity from complex equipment by utilizing the simple principle of free fall. Instead of using sophisticated machinery, the system extracts only the necessary gravitational effect through controlled free fall motion, greatly simplifying the device.
Solution Approach 2:
The system uses simple, inexpensive components such as a free-falling external module and basic sensors rather than expensive, complex equipment. The external module can be a simple structure that is discarded or reset after each experiment, eliminating the need for costly reusable complex machinery.
3Reliability
If the internal module moves independently within the external module, then the gravity change state is maintained, but position control precision is reduced without sensor feedback
Solution Approach 1:
Position detection sensors are installed in the external module to detect the position of the internal module. This feedback information is used to control the movement of the external module, ensuring that the internal module maintains the desired position and gravity state throughout the experiment.
