Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a traditional laser level projects laser beams to target points, then the basic alignment function is achieved, but accuracy deteriorates when obstructions are present
Solution Approach 1:
The system uses a controller to detect when the laser beam intersects a surface at an incorrect location, calculates the lateral distance between the actual and target intersection points, and provides feedback signals to a remote device. This feedback loop enables continuous adjustment of the laser beam aim to achieve accurate alignment even when obstructions are present.
Solution Approach 2:
The patent replaces manual mechanical adjustment of laser levels with an automated electronic control system. The controller automatically calculates lateral distances and transmits adjustment signals to a remote device, eliminating the need for manual trial-and-error positioning and improving both accuracy and efficiency.
2Ease of operation
If manual adjustment of laser levels is used, then basic alignment is possible, but installation efficiency deteriorates due to time-consuming adjustments
Solution Approach 1:
The system performs self-adjustment by automatically detecting beam intersection locations, calculating required corrections, and transmitting adjustment commands without requiring constant manual intervention. The controller and remote device work together to autonomously optimize laser beam positioning, significantly improving installation efficiency.
Solution Approach 2:
Manual mechanical adjustment operations are replaced with an automated electronic control system that calculates and transmits adjustment signals electronically. This substitution eliminates time-consuming manual adjustments and accelerates the alignment process.
3Device complexity
If laser beam aim is fixed, then device complexity is reduced, but adaptability deteriorates when target locations need adjustment
Solution Approach 1:
The system transitions from a fixed laser beam aim to a dynamic, adjustable aim controlled by electronic signals. The remote device can modify the laser beam direction based on calculated lateral distances, providing adaptability while maintaining relatively simple device architecture through software-based control rather than complex mechanical systems.
Solution Approach 2:
The laser beam parameters (specifically the aim direction) are made changeable through electronic control signals transmitted from the remote device. This allows flexible adjustment of target locations by modifying beam parameters dynamically, achieving high adaptability without substantially increasing device complexity.

AI summary
A laser level receives information describing a series of install points. The laser level than projects one or more laser beams at the install point(s), such as a planar laser beam along the run and a targeting laser beam at the point selected by the user. After the user finishes work on a first install point, the user can instruct the laser level to project the targeting laser beam at the next point, such as the user sending the instruction wirelessly.
