Solution Overview
Problem
Existing planar drive devices with electromagnetically coupled platforms lack simple and efficient mechanisms for controlling the pressure state of a medium within a storage chamber, limiting their operational flexibility and effectiveness in handling various objects.
Innovation Solution
The storage chamber is integrated on the platforms, allowing for autonomous control of the pressure state by adjusting the distance between the platforms, enabling direct transfer of the pressure state to a working tool through a fluid line, and utilizing a piston-cylinder or bellows structure for volume and pressure adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the storage chamber is integrated on the platforms with autonomous control, then the pressure state control flexibility is improved, but the device complexity increases
Solution Approach 1:
The storage chamber is integrated directly on the platforms, merging the storage function with the platform structure. This allows autonomous control of the pressure state by adjusting the distance between platforms, eliminating the need for separate external pressure control systems and reducing overall device complexity while improving flexibility.
Solution Approach 2:
The platforms serve multiple functions: they provide structural support, enable movement across the drive surface, and simultaneously act as containers for the storage chamber with autonomous pressure control. This multi-functionality improves adaptability without proportionally increasing complexity.
2Adaptability or versatility
If the distance between platforms is adjusted to control pressure, then the pressure state adjustment range is improved, but the control mechanism complexity increases
Solution Approach 1:
The system uses the platforms' own relative movement to control the pressure state. By adjusting the distance between platforms through their inherent mobility function, the system achieves pressure control without requiring separate control mechanisms, valves, or pumps. The platforms essentially control their own pressure state through self-service.
Solution Approach 2:
The pressure control is achieved through pneumatic principles by varying the volume of the storage chamber through platform distance adjustment. This allows continuous pressure adjustment ranging from vacuum to overpressure states using the existing electromagnetic coupling and mobility infrastructure.
3Measurement precision
If the storage chamber volume is changed by platform distance adjustment, then the pressure control precision is improved, but the mechanical stability worsens
Solution Approach 1:
The patent replaces traditional mechanical pressure control systems (pistons, valves, seals) with an electromagnetic field-based approach. The electromagnetic coupling between platforms and drive surface enables precise position control through field interaction, allowing accurate volume adjustment of the storage chamber without complex mechanical components that would compromise stability.
