Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If custom-designed MSM actuator systems are used for each control task, then control performance is optimized, but production cost and design complexity increase significantly
Solution Approach 1:
The actuator system is divided into modular components: flux-conducting bows, coil carriers, and expansion units. Each module can be independently designed, manufactured, and assembled. The flux-conducting bows are segmented into multiple stackable units with standardized contact sections, allowing flexible configuration for different control tasks without redesigning the entire system.
Solution Approach 2:
The standardized flux-conducting bows and coil carriers are designed as universal components that can be used across multiple applications. The same basic modules can be stacked in different quantities and configurations to meet various control requirements, eliminating the need for custom design for each control task while maintaining optimized performance.
2Reliability
If custom-designed MSM actuator systems are used for each control task, then control performance is optimized, but production efficiency decreases
Solution Approach 1:
The system is segmented into standardized modules that can be manufactured independently and assembled like LEGO blocks. The flux-conducting bows are produced as identical standardized components with consistent contact sections, enabling high-volume production through efficient manufacturing processes and reducing assembly time for different actuator configurations.
Solution Approach 2:
Instead of changing the fundamental design parameters for each application, the system maintains standardized parameters for modular components. The desired control characteristics are achieved by varying the number of stacked modules and their arrangement, not by redesigning individual components, thus enabling efficient production through parameter scaling rather than parameter redesign.
3Productivity
If standardized modular components are used, then production efficiency and adaptability improve, but magnetic flux conduction effectiveness may be compromised
Solution Approach 1:
While the overall component design is standardized, the contact sections of the flux-conducting bows are specifically optimized for magnetic flux conduction. These localized areas have enhanced properties (such as increased surface area or improved material characteristics) to ensure effective flux transfer between stacked modules, maintaining high magnetic coupling efficiency despite the modular standardized architecture.

Implementation Method 1
coil means in the form of a coil device to the magnetic shape memory material of such an expansion unit, which coil device generates the magnetic field required for expanding the expansion unit as a reaction to a current feed
Implementation Method 2
actuators of this type exploit the effect that the shape memory material (also: shape memory alloy material) experiences an expansion as a reaction to an applied magnetic field
Implementation Method 3
the electromagnetic flux generated by the current feed of the coil means is brought to the expansion unit with the aid of magnetic-flux conduction means
