Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the beam shape is made controllable to adjust coverage area, then the adaptability of the light emitting device is improved, but the communication accuracy deteriorates due to varying effect areas and position accuracy
Solution Approach 1:
The light emitting device embeds information about its current beam shape and effect area characteristics into the transmitted light signal. Receiving devices can thus obtain feedback about the actual transmission conditions, enabling them to interpret the communicated information correctly despite beam shape variations. This feedback mechanism resolves the contradiction by making the system adaptive while maintaining communication reliability.
Solution Approach 2:
The device performs preliminary characterization of its own beam shape and effect area, then uses this pre-acquired information to adjust or annotate the transmitted data. By preparing the correction information in advance based on current beam characteristics, the device ensures accurate communication regardless of how the beam shape may vary, thus maintaining reliability while allowing adaptability.
2Productivity
If the beam coverage area is expanded to reach more receiving devices, then the productivity of information transmission is improved, but the position accuracy deteriorates
Solution Approach 1:
The system segments the transmission information into multiple components: primary data and metadata about the beam's effect area and coverage characteristics. This segmentation allows receiving devices to separately process position determination data while accounting for the actual beam spread, thus maintaining position accuracy even when coverage area is expanded to reach more devices.
3Ease of operation
If the beam shape is changed to control effect area, then the ease of operation is improved, but the loss of information increases due to varying light intensity and coverage
Solution Approach 1:
The embedded metadata about beam shape and effect area provides receiving devices with feedback about the actual transmission conditions. This allows them to compensate for information loss caused by varying light intensity and coverage, ensuring accurate interpretation of the communicated data while maintaining ease of operation through beam shape control.

AI summary
A light emitting device (100) for emitting a beam of light is disclosed. The light emission of the light emitting device (100) comprises an embedded code. The light emitting device (100) comprises a beam shape controller (102) for controlling a shape of the beam of light and a first processor connected to the beam shape controller, arranged for generating the embedded code. The first processor (104) is further arranged for embedding a message in the embedded code based on the shape of the beam of light. This allows the light emitting device (100) to communicate information to a receiving device based on its effect area (i.e. the illuminated area). This information may, for example, comprise information about the beam shape and size, which may be used to determine an area wherein the receiving device is located relative to the light emitting device (100).
