Engineering Contradiction Analysis
1Productivity
If multiple laser systems are employed on the same construction site, then productivity and measurement capability are improved, but the risk of erroneous identification between laser devices increases
Solution Approach 1:
The patent applies the principle of color changes by using different rotation patterns (analogous to color codes) for different laser devices. Each laser device emits a unique rotation pattern that serves as its identifier, allowing detectors to distinguish between multiple laser systems on the same construction site. The rotation pattern acts as a visual signature similar to how different colors differentiate objects.
Solution Approach 2:
The patent implements parameter changes by varying the rotation speed and pattern parameters of the laser beam. By changing these rotational parameters, each laser device creates a distinct identification signature. The system modulates the rotation speed and pattern to encode unique identifiers, enabling reliable differentiation between multiple laser systems while maintaining high productivity.
2Productivity
If a laser beam rotates at high speed to improve measurement efficiency, then productivity increases, but the complexity of detecting and measuring the rotation pattern increases
Solution Approach 1:
The patent introduces an intermediary communication channel (radio frequency communication) that mediates between the rotating laser beam and the detector. Instead of relying solely on direct optical detection of the rotating pattern, the system uses RF communication to transmit rotation pattern information, significantly simplifying the detection process while maintaining high rotation speeds for improved productivity.
Solution Approach 2:
The patent replaces the mechanical/optical detection system with an electronic communication system. Rather than using complex optical sensors to directly detect and measure the rotating laser pattern, the system substitutes this with RF communication that electronically transmits rotation pattern data, reducing measurement difficulty while enabling faster rotation speeds.

AI summary
The present invention relates to a laser device for supporting work on a construction site and a laser beam detector for detecting light of a laser beam rotating around a rotation axis of a laser device. There is a need that the detector is able to identify the laser device which emitted the light that the detector detects. This can be achieved by a laser device comprising a laser unit configured to emit a laser beam; an optical element arranged to rotate the laser beam around a rotation axis; and a transmitter configured to transmit a communication signal over an interface to a receiver of a laser beam detector, wherein the communication signal provides information about a rotation pattern of the rotating laser beam.
