Laser Level With Offset Cone Mirror for Directional Power
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing laser levels lack an improved construction that optimizes laser beam projection for enhanced power distribution and versatility in various orientations.
Innovation Solution
The laser level incorporates a laser module with a collimating lens and cone mirror configuration, where the optical axis is offset to enhance power distribution, allowing for higher power in specific directions, such as upward or forward, by adjusting the offset distance between 0.4 mm to 1.2 mm, and includes multiple laser modules for 360-degree projection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If the optical axis is offset from the apex of the cone mirror, then power distribution is optimized with higher power in specific directions, but uniform power distribution in all directions is compromised
Solution Approach 1:
The patent applies asymmetry by deliberately offsetting the optical axis from the apex of the cone mirror by a specific distance (0.4mm to 1.2mm). This asymmetric configuration causes the laser beam to reflect with higher power in specific directions (upward and forward) rather than uniformly in all directions, resolving the contradiction between optimized directional power and uniform power distribution.
2Power
If the offset distance is increased to enhance power in specific directions, then power distribution is improved, but precision of laser line projection is reduced
Solution Approach 1:
The patent applies parameter changes by optimizing the offset distance within a specific range (0.4mm to 1.2mm). This controlled parameter adjustment achieves the desired power distribution improvement while maintaining acceptable precision for laser line projection, resolving the contradiction between power enhancement and projection precision.
