Solution Overview
Problem
Existing directional heads for aligning and tracking targets, such as aircraft, face challenges in minimizing aerodynamic influences and maintaining low weight while ensuring contactless energy and data transmission, especially when components need to rotate and are subject to mechanical stress, making traditional sliding contacts unsuitable for long-term use.
Innovation Solution
The solution involves a contactless energy and data transmission arrangement using annular and rotatably interlocking bearing flanges with modular transmission elements, including low-loss segmented core structures with radially arranged U-cores and annular windings, allowing for coaxial alignment of beam paths with energy and data transmission modules, and utilizing capacitive signal transmission through integrated annular or cylindrical capacitor plates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If sliding contacts are used for energy and data transmission in rotating components, then mechanical connection is established, but maintenance-free long-term use is excluded due to wear and mechanical stress
Solution Approach 1:
The patent replaces mechanical sliding contacts with an inductive coupling system using magnetic fields. A transmitter coil in the stationary part and a receiver coil in the rotating part create a magnetic coupling that transfers energy and data without mechanical contact, eliminating wear and enabling maintenance-free operation while allowing continuous rotation
Solution Approach 2:
The patent introduces a magnetic field as an intermediary between the stationary and rotating parts. The magnetic field serves as the medium for energy and data transmission, allowing the system to overcome the limitation of mechanical contacts while maintaining reliable coupling across the air gap
2Object-affected harmful factors
If beam paths are superimposed in parallel to achieve common aperture, then aerodynamic influences are minimized, but alignment precision becomes more difficult
Solution Approach 1:
The patent merges the beam paths of the laser and tracker sensors into a common aperture by superimposing them in parallel. This integration allows both optical paths to share the same opening, minimizing aerodynamic interference while maintaining precise alignment through careful optical design and positioning
Solution Approach 2:
The patent addresses alignment precision by introducing additional degrees of freedom in the positioning system. Multiple adjustment mechanisms allow alignment in both azimuth and elevation directions, enabling precise beam superposition while maintaining the parallel configuration that reduces aerodynamic effects
3Use of energy by moving object
If transformer coils are arranged coaxially in tubular parts for contactless energy transmission, then electromagnetic induction is achieved, but rotational movement and alignment flexibility are restricted
Solution Approach 1:
The patent designs the transmitter and receiver assemblies to serve multiple functions: they provide inductive energy transmission through coaxial coil arrangements while simultaneously enabling rotational movement and azimuth/elevation alignment. The universal design allows the same structure to achieve both efficient energy transfer and flexible positioning
Solution Approach 2:
The patent introduces dynamic capabilities to the inductive coupling system by allowing the transmitter and receiver assemblies to rotate and align in multiple directions. The coils maintain their coaxial relationship during movement, enabling the system to adapt its orientation while preserving efficient electromagnetic coupling

AI summary
The arrangement has a transmission unit designed as a transmission module, and contactlessly bridging an air gap. The transmission unit is arranged around a central free space (20) as a circular module bank with module halves that are moveably supported relative to each other. A ball bearing arranged between bearing rings that are held by a circular plate screwed with a bar of the bearing rings. The transmission module serves to transform a signal transmission that exhibits twisted tapping, which is controlled via a rotary drive.
