Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional drive systems are used to move large masses in the simulator, then the simulator can achieve required motion ranges, but the drive technology demands become excessively high and the structure becomes complex
Solution Approach 1:
The patent replaces traditional direct mechanical drive systems with a cable-driven mechanism. Motors mounted on the stationary foundation drive cables that pass through pulleys to move the heave carriage and rotate the carriage basket. This substitution reduces the mechanical complexity at the moving components while maintaining the ability to simulate various flight conditions.
Solution Approach 2:
Instead of mounting motors on the moving carriage to directly drive it, the patent inverts the approach by mounting motors on the stationary foundation and using cables to transmit force to the moving components. This inversion simplifies the moving structure while achieving the same functional outcomes.
2Productivity
If motors are mounted on the moving carriage to drive it, then direct drive is achieved, but the system becomes complex and costly
Solution Approach 1:
The patent inverts the conventional approach by mounting motors on the stationary foundation rather than on the moving carriage. The motors drive cables that pass through pulleys to move the heave carriage and rotate the carriage basket, significantly reducing manufacturing complexity and cost while maintaining operational efficiency.
Solution Approach 2:
The patent introduces cables and pulleys as intermediary elements between the stationary motors and the moving components. This intermediary mechanism allows force transmission without requiring motors to be mounted on the moving carriage, simplifying the overall system and reducing production costs.
3Device complexity
If a cable drive system is used with motors on the foundation, then device complexity and cost are reduced, but the system must effectively transmit forces to move large masses
Solution Approach 1:
The patent uses pulleys (circular/spheroidal elements) to guide and transmit cable forces. The pulleys mounted on the heave carriage and carriage basket efficiently transmit the cable tension forces to move the large masses, maintaining force transmission capability while keeping the system simple and cost-effective.
Solution Approach 2:
The cables act as intermediaries that transmit forces from the stationary motors to the moving components. Combined with pulleys that redirect and transmit these forces, the system effectively moves large masses while maintaining structural simplicity and reducing overall system complexity.
