Multi-Axis Laser Level Micro-Adjustment for Precise Leveling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing laser levels, particularly manual types, require cumbersome manual adjustments to ensure the laser beam is emitted along a level plane, lacking an easy and precise adjustment mechanism.
Innovation Solution
A laser level with a housing that is pivotable about three axes and equipped with micro-adjustment knobs for fine tuning along two additional axes, facilitated by bubble levels for alignment, allowing both bulk and micro-adjustments for precise laser orientation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual laser levels are used, then the device structure is simple, but the adjustment precision and ease of operation are poor
Solution Approach 1:
The adjustment system is segmented into two distinct components: macro-adjustment knobs for coarse positioning and micro-adjustment knobs for fine-tuning. This segmentation allows users to first achieve rough alignment quickly, then refine the precision without being constrained by a single complex adjustment mechanism.
Solution Approach 2:
The patent introduces multi-axis adjustment capabilities (pitch, yaw, and roll axes) to the traditional single-axis manual laser level. By adding adjustment dimensions, the device achieves comprehensive precision control while maintaining a relatively simple overall structure through modular design.
2Measurement precision
If multiple adjustment knobs are added, then the adjustment precision is improved, but the device complexity increases
Solution Approach 1:
The bubble level indicators are strategically positioned to provide immediate visual feedback for each adjustment knob's effect. Users can self-correct their adjustments by observing the bubble position relative to the crosshair reticle, eliminating the need for complex external measurement tools or multiple adjustment steps.
Solution Approach 2:
The patent incorporates real-time visual feedback through bubble levels that directly indicate the alignment status for each axis. This feedback loop allows users to make precise adjustments by simply observing the bubble position and making corresponding knob rotations, significantly improving ease of operation despite having multiple adjustment mechanisms.
3Extent of automation
If self-leveling mechanism is used, then the automatic adjustment capability is improved, but the device complexity and cost increase
Solution Approach 1:
The patent provides a hybrid system where the housing can be dynamically adjusted manually when precision is needed, while the base remains stationary and stable. This dynamic manual adjustment capability replaces complex automatic self-leveling mechanisms, achieving high precision through user control rather than automated sensors and motors.

AI summary
A laser level includes a housing having a laser emitter to emit a laser along a plane. The laser level includes a mounting base connected to the housing. The housing is pivotable relative to the mounting base about three axes by a user grasping the housing and moving the housing. The housing includes a first micro-adjustment knob to adjust the housing, relative to the mounting base, about a fourth axis. The housing includes a second micro-adjustment knob to adjust the housing, relative to the mounting base, about a fifth axis perpendicular to the fourth axis.
