Rotating Laser Level Tracking Moving Detector Trajectory
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing laser levels are unable to measure different distances at different angles or plot a trajectory map of a traveling route due to their fixed base, which restricts their ability to rotate and follow the movement of a detector.
Innovation Solution
A method and system that includes a laser emitting device with a driving mechanism allowing the housing to rotate relative to the base, enabling the emission of laser beams at various angles, and a communication system between the emitting and receiving devices to track the movement and calculate distances and angles, allowing for the recording and plotting of a trajectory map.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the laser level uses a fixed base to maintain stability, then the instrument remains stable and easy to operate, but it cannot rotate to follow the movement of the detector, limiting measurement capability
Solution Approach 1:
The patent applies the dynamics principle by transforming the fixed base into a rotatable base. The base is now capable of rotating around the vertical axis while maintaining stability during operation. This allows the laser level to dynamically adjust its orientation and follow the movement of the detector, enabling measurements at different angles and positions without sacrificing operational stability.
2Device complexity
If the laser level remains fixed to a reference surface, then the structure remains simple and cost-effective, but it cannot track the trajectory of a moving detector
Solution Approach 1:
The patent applies the universality principle by enabling the laser level to perform multiple functions. In addition to its traditional function of emitting a leveled laser plane, the instrument now also functions as a tracking device that can follow the detector's movement and record trajectory information. This multi-functionality is achieved through the rotatable base and integrated sensors, allowing a single device to replace what would traditionally require separate instruments.
Solution Approach 2:
The patent introduces an intermediary mechanism in the form of a rotatable base with integrated sensors (encoder, gyroscope, accelerometer) that mediates between the fixed reference surface and the moving detector. This intermediary captures the rotational position and movement data, enabling the system to track the detector's trajectory while maintaining the simplicity of the overall structure.
3Productivity
If the laser beam only sweeps on the leveled plane, then the rotating head is sufficient without rotating the instrument, but different distances at different angles cannot be measured
Solution Approach 1:
The patent applies the dynamics principle by enabling the entire instrument to rotate dynamically in response to the detector's position. Instead of the laser beam merely sweeping on a fixed leveled plane, the instrument itself rotates to orient the laser beam toward the detector at different angles and distances. This dynamic rotation is controlled by sensors that detect the detector's position, ensuring accurate distance measurements at various angles while maintaining operational efficiency.

AI summary
The present disclosure provides a method for measuring an angle and a distance.
