Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a traditional orbital machine with fixed displacement is used, then the machine structure is simple, but the machine lacks versatility and cannot manage shaft rotation speed and torque effectively
Solution Approach 1:
The stator case is divided into two distinct portions: a first stator case portion and a second stator case portion. Each portion has chambers with minimum volumes at different angular positions, allowing independent control of displacement phases. This segmentation enables the machine to achieve variable displacement functionality while maintaining a relatively simple overall structure.
Solution Approach 2:
The invention introduces dynamic adjustability by enabling relative rotation between the first and second stator case portions around the common rotation axis. This dynamic configuration allows the angular offset between chambers to be varied during operation, providing continuous displacement control and transforming the machine from fixed to variable displacement operation.
2Adaptability or versatility
If circuit systems or reduction systems are added to manage varying shaft rotation speed and torque, then machine versatility improves, but system complexity and costs increase
Solution Approach 1:
The orbital machine is designed to perform multiple functions within a single integrated structure. By incorporating two stator case portions with adjustable angular offset, the machine can directly manage varying shaft rotation speed and torque requirements through displacement control, eliminating the need for separate circuit systems or reduction systems that would otherwise be required.
Solution Approach 2:
The angular offset between the first and second stator case portions acts as an intermediary mechanism for controlling displacement. By adjusting this offset, the machine mediates between different operational requirements for shaft rotation speed and torque, providing smooth transition and control without requiring complex external systems.
3Speed
If axial units are used to achieve higher rotation speeds, then displacement control improves, but the need for reduction systems increases complexity
Solution Approach 1:
The dynamic relative rotation between stator case portions enables the machine to operate efficiently across a range of rotation speeds without requiring fixed geometric configurations. This dynamic adaptability allows the machine to maintain optimal performance at various speeds, reducing or eliminating the need for reduction systems.
4Adaptability or versatility
If solutions with plurality of inlets and outlets are used, then displacement variability improves, but only binary switching is achieved limiting versatility
Solution Approach 1:
Rather than relying on binary switching between fixed displacement modes, the invention employs continuous dynamic adjustment of the angular offset between stator case portions. This enables smooth, progressive variation of displacement across a continuous range, providing superior operational flexibility and versatility compared to binary switching solutions.
