Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a classical interface arrangement with central holding device and outer bearing elements is used, then mechanical coupling is achieved, but flexibility for energy transmission and data transmission is limited
Solution Approach 1:
The interface arrangement is divided into functionally distinct zones: a central area for optical interfaces and an outer area for mechanical bearing and electrical interfaces. This segmentation allows each zone to be optimized for its specific function, enabling flexible energy and data transmission while maintaining mechanical coupling.
Solution Approach 2:
The interface arrangement integrates multiple transmission methods (optical, electrical, mechanical) within a single structure. The central area handles optical data transmission, the outer area provides mechanical positioning and electrical connections, creating a multi-functional interface that can accommodate various sensor types and transmission requirements.
2Reliability
If mechanical contact interfaces are used for data transfer, then connection stability is achieved, but susceptibility to electrical interference increases
Solution Approach 1:
The patent replaces mechanical contact-based data transmission with optical transmission in the central area. Optical interfaces transmit data without electrical contact, eliminating electrical interference while maintaining connection stability through the mechanical bearing structure in the outer area.
Solution Approach 2:
Optical interfaces act as an intermediary between system components, enabling data transmission without direct electrical contact. This intermediary approach allows stable communication while blocking electrical interference from affecting the data transmission path.
3Productivity
If high data transmission rates are required, then optical interfaces are needed, but mechanical positioning precision may be compromised
Solution Approach 1:
The interface is segmented into a central optical area and an outer mechanical bearing area. This separation allows the optical interfaces to achieve high data transmission rates without compromising mechanical positioning precision, as the bearing elements in the outer area maintain accurate alignment while the central area handles high-speed optical communication.
