Laser Calibration Device Directional Locking Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional laser calibration apparatuses require frequent re-leveling during operations like height adjustment or movement, which is time-consuming and prone to large-angle tilts, due to the lack of precise control over the auto-leveling element's movements.
Innovation Solution
A laser calibration apparatus with an auto-leveling element that restricts only the front-and-rear swinging direction, allowing sufficient leveling freedom during debugging and maintaining leveling in other directions during formal operations, preventing undesirable tilts and motion dead points.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the auto-leveling element is equipped with omni-directional locking to maintain precise leveling, then leveling precision is improved, but the apparatus requires frequent re-leveling during operations like height adjustment or movement, which is time-consuming
Solution Approach 1:
The locking function is segmented into direction-specific locks: a first locking member for front-and-rear direction and a second locking member for left-and-right direction. This allows selective locking of individual directions rather than requiring omnidirectional locking, enabling operations in locked directions while maintaining precision in other directions.
Solution Approach 2:
The system dynamically adjusts the locking state of different directions based on operational needs. The locking members can be independently engaged or disengaged, allowing the apparatus to transition between locked and unlocked states in specific directions without requiring complete re-leveling.
2Ease of operation
If the auto-leveling element allows free swinging in all directions to facilitate debugging and adjustment, then ease of operation is improved, but the apparatus may experience large-angle tilts and motion dead points during formal operations
Solution Approach 1:
The swinging freedom is segmented by direction through separate locking members. During debugging, both locking members can be disengaged to allow free adjustment in all directions. During formal operations, the first locking member can be engaged to prevent front-and-rear tilts while the second remains disengaged to allow left-and-right adjustment, avoiding motion dead points.
Solution Approach 2:
Different directional constraints are applied locally based on operational requirements. The front-and-rear direction can be locked to prevent large-angle tilts, while the left-and-right direction remains unlocked to maintain adjustment capability, creating direction-specific stability characteristics.

Function Achieved in This Case
Facilitates efficient debugging and maintains precise leveling during operations by allowing sufficient leveling freedom before locking, reducing the need for frequent re-leveling and minimizing tilts, thus enhancing operational efficiency and accuracy.

AI summary
A laser calibration apparatus includes: a laser generating apparatus having: a housing; a laser generator disposed within the housing and configured to generate a calibration laser; and an auto-leveling element disposed within the housing, the auto-leveling element being connected to the laser generator and configured to drive, the laser generator to swing in multiple directions, such that the calibration laser generated by the laser generator is parallel to the horizontal plane. The laser calibration apparatus has a semi-locked state, in which swinging of the auto-leveling element in a front-and-rear direction is restricted. The laser generating apparatus is provided with sufficient leveling freedom before forward and backward swinging of the auto-leveling element is locked, and the forward and backward swinging of the auto-leveling element is locked after the leveling is completed, thereby avoiding issues such as motion dead points.
