Solution Overview
Problem
Existing self-levelling multi-line laser devices are complex, costly, and have high energy consumption due to their mechanical design and reliance on rotating parts, which limits their reliability and precision over time.
Innovation Solution
A self-levelling multi-line laser device with three line projection devices, each featuring a reflecting cone and a laser beam directed towards the cone's apex, utilizing cylindrical, transparent cone carriers to generate three mutually perpendicular laser lines that can be projected over 360° without rotating parts, using laser diodes and collimating optics for precise alignment and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If rotating deflection elements are used to generate laser lines, then laser lines can be projected over 360°, but the device becomes mechanically complex and costly
Solution Approach 1:
The patent replaces the mechanical rotating deflection element with a static reflecting cone that has a specific geometric shape. The cone's surface is designed to reflect the laser beam in all directions simultaneously, eliminating the need for mechanical rotation while achieving 360° projection coverage. This substitution of mechanical motion with a geometric optical solution resolves the contradiction between angular range and device complexity.
2Adaptability or versatility
If rotating parts are used to generate laser lines, then 360° projection is achieved, but reliability decreases due to wear and tear
Solution Approach 1:
The patent eliminates all rotating mechanical parts by using a stationary reflecting cone with a specially designed surface geometry. The cone's reflective surface is shaped to redirect the laser beam in all directions without requiring any motion. This static optical solution removes wear and tear associated with rotating components, significantly improving device reliability while maintaining 360° projection capability.
3Measurement precision
If complex mechanical systems are used for self-levelling, then alignment accuracy is improved, but manufacturing costs increase
Solution Approach 1:
The patent replaces complex mechanical self-levelling systems with a simple gravitational pendulum mechanism. The optics carrier is suspended as a pendulum that automatically aligns itself with the gravitational vector, providing self-levelling functionality through a passive mechanical advantage rather than active control systems. This simplified approach maintains alignment accuracy while dramatically reducing manufacturing complexity and cost.
4Adaptability or versatility
If rotating laser units are combined to generate multiple lines, then multi-line projection is achieved, but device weight increases
Solution Approach 1:
The patent merges multiple laser line generation functions into a single compact optics carrier that houses multiple reflecting cones and laser sources. Instead of separate rotating laser units, the invention integrates three laser sources and three reflecting cones into one unified structure, all mounted on a common pendulum-suspended carrier. This consolidation achieves multi-line projection capability while minimizing device weight through shared mechanical support and compact optical arrangement.
