Laser Level Cone-Mirror Optics for Asymmetric Beam Power
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing laser levels lack an improved construction that optimizes laser beam projection for enhanced performance and versatility.
Innovation Solution
The laser level incorporates a laser module with a collimating lens and cone mirror configuration that offsets the optical axis upward, allowing for a higher power portion directed upward and a lower power portion directed opposite, with adjustable offsets ranging from 0.4 mm to 1.2 mm, and includes multiple laser modules for projecting laser lines in both vertical and horizontal planes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If the optical axis is offset upward from the cone mirror apex, then the power distribution of the laser line is optimized with higher upward power, but the symmetry of the laser projection is reduced
Solution Approach 1:
The patent applies asymmetry by intentionally offsetting the optical axis of the laser module upward from the apex of the cone mirror by a specific distance (0.4mm to 1.2mm). This asymmetric positioning creates unequal power distribution in the laser line, with the upward portion receiving higher power and the downward portion receiving lower power, thereby optimizing power distribution for specific applications while accepting reduced symmetry
2Adaptability or versatility
If multiple laser modules are included for vertical and horizontal projection, then the versatility of the laser level is improved, but the device complexity increases
Solution Approach 1:
The patent implements multi-functionality by integrating multiple laser modules within a single device - one module configured for vertical plane projection (360 degrees) and another for horizontal plane projection (360 degrees). This universal design allows the laser level to perform multiple functions (vertical leveling, horizontal leveling, crosshair alignment) simultaneously, enhancing versatility while managing complexity through integrated housing design

Function Achieved in This Case
This configuration enhances beam projection efficiency, enabling more focused power distribution for specific applications, such as directing more power towards ceilings or floors, and supports stable leveling on uneven surfaces.
Implementation Method 1
The laser module includes a laser generator, a collimating lens and a cone mirror. The laser module may be configured to project a laser line in a vertical plane generally about 360 degrees.
Implementation Method 2
The laser generator generates a laser beam which passes through the lens and reflects off of the cone mirror.
