Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional data transmission methods are used in rotating arm links, then mechanical interfaces can be established, but data transmission integrity deteriorates due to rotation and mechanical limitations
Solution Approach 1:
The patent replaces mechanical data transmission interfaces with a wireless communication system. Transmitters and receivers are integrated into the arm modules, allowing data to be transmitted wirelessly between rotating components, thereby eliminating the constraint of mechanical interfaces on rotation capability while maintaining reliable data transmission.
Solution Approach 2:
The patent introduces wireless signals as an intermediary medium to transfer data between arm modules. Instead of direct mechanical contact, data is transmitted through electromagnetic waves, allowing continuous data flow even when arm links rotate relative to each other without physical connection constraints.
2Adaptability or versatility
If multiple interfaces from different manufacturers are used, then various functions can be integrated, but device complexity increases
Solution Approach 1:
The patent implements a universal wireless communication interface that can handle multiple functions (data transmission, control signals, feedback) through a single standardized protocol. This multi-functional approach eliminates the need for multiple specialized interfaces from different manufacturers, reducing overall system complexity while maintaining versatility.
Solution Approach 2:
The patent combines multiple communication functions into a unified wireless transmission system. Instead of separate mechanical and electrical interfaces for different functions, all data and control signals are merged into a single wireless communication channel, simplifying the interface architecture.
3Reliability
If drag chains are used to guide lines, then mechanical connections are maintained, but rotation freedom is restricted
Solution Approach 1:
The patent replaces the mechanical drag chain system with wireless communication technology. This substitution eliminates the physical constraints imposed by drag chains on arm rotation, allowing free rotation while maintaining reliable data transmission through electromagnetic fields that are not subject to mechanical winding or twisting limitations.

AI summary
An arm module includes a housing with a first connection side controllably rotatable relative to a second connection side, about an axis of rotation. The first connection side has a rotatable first connection device. The second connection side has a second connection device fixed to the housing, with a rotation-compatible data transmission device for transmitting data signals along at least one transmission path between the first and second connection sides. The transmission path includes at least one wireless transmission sub-path for wireless transmission of data signals, and at least one wire-guided transmission sub-path for wire-guided transmission of data signals. The rotation-compatible data transmission device includes at least one first wireless transmission unit and at least one second wireless transmission unit, interconnected via the transmission path and arranged to wirelessly transmit and receive data signals along the wireless transmission sub-path. An industrial robot can have a plurality of such arm modules.
