Solution Overview
Problem
Conventional optical wireless data transmission systems experience data interruptions when the distance between rotatable transmitter/receiver units is small compared to their size, leading to issues with maintaining visual contact and ensuring continuous data connection.
Innovation Solution
An optical transmitter/receiver unit design that integrates receiving and transmitting optics, allowing the transmission beam to propagate along the axis of rotation, ensuring continuous data transmission regardless of the relative rotational position between units.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the distance between transmitter and receiver is reduced to achieve compact system size, then the system becomes more space-efficient, but visual contact is lost and data transmission is interrupted
Solution Approach 1:
The patent positions the transmitter and receiver on the same rotation axis rather than opposite sides, utilizing axial alignment to maintain visual contact. This dimensional reconfiguration allows the optical path to remain unobstructed during rotation, solving the contradiction between compact size and transmission reliability.
Solution Approach 2:
The transmitter and receiver are integrated into a single rotatable component that serves both transmission and reception functions simultaneously. This multi-functional design eliminates the need for separate opposing units, reducing system volume while maintaining continuous optical contact through shared axial positioning.
2Device complexity
If conventional separate transmitter and receiver units are used in rotatable components, then the system structure is simple, but data transmission is interrupted when units rotate out of alignment
Solution Approach 1:
The transmitter and receiver are merged into a single integrated unit positioned on the rotation axis, eliminating the need for separate opposing units. This combination maintains continuous visual contact during rotation while simplifying the overall system structure through unified positioning.
Solution Approach 2:
The patent transitions from a lateral/opposite positioning arrangement to an axial/collinear arrangement along the rotation axis. This dimensional change ensures that the optical path remains aligned during rotation, maintaining data connection continuity without requiring complex alignment mechanisms.
3Adaptability or versatility
If optical transmitters and receivers are positioned opposite each other, then the system follows conventional design, but rotation causes loss of line of sight and transmission interruption
Solution Approach 1:
The patent repositions components from opposite lateral locations to collinear axial locations on the rotation axis. This dimensional transformation allows the system to maintain visual contact during rotation, as the optical path remains aligned along the axis regardless of rotational position, thereby improving both adaptability and reliability.
Solution Approach 2:
Instead of positioning transmitters and receivers opposite each other across the rotation axis, the patent inverts the approach by placing them on the same axis. This inverted configuration fundamentally changes the geometric relationship, ensuring continuous optical contact while maintaining full rotational flexibility.

AI summary
The invention relates to an optical transceiver unit (200) comprising a carrier (210) that can be rotated about an axis of rotation (206), an optical receiver (204) which is arranged on the carrier (210) on the axis of rotation (206) in order to receive an optical receiving signal (226) from a first direction, an optical transmitter (202) which is arranged on the carrier (210) that is adjacent to the optical receiver (204), in order to transmit an optical transmission signal in a second direction, and an optical transceiver system (214) which is arranged on the carrier (210) on the axis of rotation (206) above the optical receiver (204) and extends over the optical receiver (204) and the optical transmitter (202). The optical transceiver system (214) comprises an optical receiving system (218) and an optical transmission system arranged in the optical receiving system (218). The optical receiving system (218) is designed to guide the optical receiving signal incident on the transceiver unit (214) towards the optical receiver (204) on the axis of rotation (206), and the optical transmission system is designed to move the optical transmission signal (208) on the axis of rotation (206) emitted by the optical transmitter (202) such that a transmission signal (226) exits the transceiver system (214) in the region of the axis of rotation (206).
