Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If heavy machinery modules are made fixed and stable for operation, then operational reliability is improved, but maintenance access and module reconfiguration become difficult
Solution Approach 1:
The sortation system is divided into multiple independent modules that can be separated from each other. Each module can be accessed, maintained, or reconfigured independently while the rest of the system continues to operate, resolving the contradiction between operational reliability and maintenance access.
Solution Approach 2:
The system transitions from a fixed configuration to a dynamic, reconfigurable configuration. Modules can be moved between operational and maintenance states using robotic systems and air bearing technology, allowing the system to adapt between requiring stability during operation and accessibility during maintenance.
2Ease of repair
If machine modules are separated for maintenance, then ease of repair is improved, but system complexity increases
Solution Approach 1:
The robotic systems and air bearing mechanisms serve multiple functions: they enable module separation for maintenance, facilitate module reconfiguration for different operational modes, and support both heavy and light modules. This multi-functionality reduces overall system complexity despite the added capability of module separation.
3Ease of operation
If manual movement of modules is enabled, then ease of operation is improved, but friction and energy loss increase
Solution Approach 1:
Air bearing technology is used to create a pneumatic cushion between modules and the support surface. This pneumatic layer dramatically reduces friction during manual movement while requiring minimal energy to maintain, resolving the contradiction between ease of operation and energy loss.

AI summary
Systems, methods, and apparatuses are disclosed for external mobility systems for heavy machinery and equipment. In one embodiment, an example system may include a first module, a second module coupled to the first module, and a third module coupled to the first module and the second module. Systems may include an air bearing system disposed under the third module, where the air bearing system is configured to apply an upward force on the third module, and an air supply coupled to the air bearing system. The upward force on the third module may reduce a static friction of the third module with respect to a floor surface by at least 90%, such that the third module can slide from a default position to an expanded position.
