Automatic Laser Stand Height Adjustment via Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for adjusting the height of stands used with laser devices, such as tripods, require manual operation and often necessitate a second operator, especially in outdoor conditions with limited visibility, and lack efficient communication for automatic height adjustment.
Innovation Solution
A method that enables automatic height adjustment of a stand by transmitting control signals from a laser receiver to the height adjustment device via a communication link, allowing the stand to move until the laser beam hits a detector, with optional communication for deactivating shock functions and integrating the laser device for full automation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual height adjustment of the stand is used, then the stand can be adjusted to the desired height, but a second operator is required especially outdoors with limited visibility
Solution Approach 1:
The stand performs height adjustment automatically using its own laser device and detector to sense position and control the drive mechanism, eliminating the need for external operators or assistance
Solution Approach 2:
The laser detector continuously monitors the laser beam position and feeds this information back to the control unit, which automatically adjusts the stand height until the beam hits the detector, enabling self-regulating operation
2Ease of operation
If a remote control is used to adjust the wall bracket, then the laser device can be positioned, but the operator must first read the difference between actual and target position manually
Solution Approach 1:
The system automatically reads the difference between actual and target position through the laser detector and control unit, which continuously monitor beam position and calculate required adjustments without manual intervention
Solution Approach 2:
The manual reading and control process is replaced by an automated optical-electronic system where the laser detector and control unit directly sense position differences and execute adjustments without human calculation or input
3Object-affected harmful factors
If the laser power is limited for safety, then protective measures are not needed, but the laser beams are not visible or difficult to see outdoors
Solution Approach 1:
The laser detector senses the low-power laser beam and provides feedback to the control unit, which uses this information to automatically adjust the stand position, making the visibility issue irrelevant to the adjustment function
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables single-operator, fully automatic height adjustment of laser device stands, improving visibility and efficiency by eliminating the need for manual control and allowing the laser device to be used for its primary functions post-adjustment.
Implementation Method 1
laser devices that generate point and/or linear laser beams
Implementation Method 2
a laser beam is directed onto a detector device of the laser receiver

AI summary
The device (1) has a receiving unit (12) receiving a laser apparatus (5), which is adjusted in a vertical direction (15) by an automatic height setting unit (16). A laser receiver (3) is connected with the height setting unit over a communication link, which is designed in a form of radio or infrared connection. The laser receiver is connected with the laser apparatus over the communication link. A switch device is switched between an active state and a deactivated state, where the laser receiver is reversible between two modes of operation. An independent claim is also included for a method for adjusting height of a stand in a vertical direction.
