1Volume of moving object
If the coupling device uses traditional joint devices without support devices, then the structure is simpler, but the radial installation space is not optimally utilized and large deflection angles cannot be accommodated
Solution Approach 1:
The coupling device is divided into multiple levels with first and second couplings arranged at different radial positions. Each coupling contains thread-reinforced joint devices that can be independently positioned and supported, allowing the system to accommodate large deflection angles while optimizing radial space utilization.
Solution Approach 2:
The patent introduces a vertical dimension by arranging couplings at different radial levels (first coupling at outer radial position, second coupling at inner radial position). This multi-level arrangement allows the coupling device to accommodate large deflection angles while maintaining compact radial footprint, effectively utilizing the available radial installation space.
2Adaptability or versatility
If the coupling device accommodates large deflection angles, then the adaptability is improved, but the axial installation space increases
Solution Approach 1:
Instead of accommodating deflection angles through axial extension, the patent utilizes the radial dimension by arranging multiple couplings at different radial levels. The first coupling is positioned at an outer radial position while the second coupling is positioned at an inner radial position, allowing large deflection angle accommodation within a compact axial footprint.
Solution Approach 2:
The coupling device incorporates elastic bodies that provide flexibility and dynamic adaptation to deflection angles. The elastic bodies allow the joint devices to accommodate angular movements while maintaining a compact structure, enabling the coupling device to adapt to various operational conditions without requiring excessive axial space.
3Volume of moving object
If the thread-reinforced joint devices are held in predetermined radial positions by support devices, then the radial space utilization is optimized, but the device complexity increases
Solution Approach 1:
The support devices serve multiple functions: they hold the thread-reinforced joint devices in predetermined radial positions, provide structural support for the multi-level coupling arrangement, and enable the accommodation of large deflection angles. This multi-functionality reduces the need for additional separate components, thereby optimizing radial space utilization without proportionally increasing overall device complexity.
