Adjustable Laser Engraver Housing for Variable Object Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current laser engravers lack flexible mechanisms for adjusting the orientation and spacing of the laser beam relative to the engraving surface, limiting their ability to accommodate objects of varying sizes and shapes effectively.
Innovation Solution
The laser engraver features a system with screw-type adjusters on the side panels for height and angle adjustments, a removable plate with internal screw mechanisms for further angle and height adjustments, and a height- and level-adjustable cart to support larger objects, allowing the laser beam to be directed through the open bottom and top of the housing for precise engraving.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed laser housing structure is used, then the device complexity is reduced, but the adaptability to accommodate objects of varying sizes and shapes deteriorates
Solution Approach 1:
The patent applies the dynamics principle by making the laser housing structure adjustable rather than fixed. The housing includes height adjustment mechanisms and angle adjustment mechanisms that allow the laser beam to be dynamically repositioned vertically and angularly. This enables the system to adapt to objects of varying sizes and shapes while maintaining a relatively simple overall structure through modular adjustment components.
Solution Approach 2:
The patent segments the adjustment system into distinct functional modules: height adjustment mechanisms (screw shafts with nuts), angle adjustment mechanisms (separate screw mechanisms), and a removable plate. This segmentation allows each component to perform a specific adjustment function independently, improving adaptability while keeping the overall device complexity manageable through modular design.
2Measurement precision
If multiple adjustment mechanisms are added to the laser housing, then the positioning precision of the laser beam is improved, but the device complexity increases
Solution Approach 1:
The patent implements dynamic adjustment capabilities through multiple independent mechanisms: height adjustment via screw shafts and nuts, angle adjustment via separate screw mechanisms, and optional plate removal. These dynamic adjustments enable precise positioning of the laser beam in both vertical and angular dimensions, achieving high measurement precision while maintaining operational simplicity through well-defined mechanical interfaces.
Solution Approach 2:
The adjustment system is segmented into distinct functional units: height adjustment (screw shafts and nuts), angle adjustment (screw mechanisms), and a removable plate. Each segment handles a specific aspect of positioning, allowing for precise control without creating a monolithic complex system. The modular nature of these segments makes the overall system manageable despite the multiple adjustment capabilities.
3Stability of the object's composition
If the bottom of the laser housing is closed with a plate, then the structural stability is improved, but the ease of operation for accessing objects under the housing deteriorates
Solution Approach 1:
The patent applies the dynamics principle by making the housing bottom configurable - it can be closed with a plate for structural stability during operation, or opened by removing the plate for easy access to objects underneath. This dynamic reconfiguration allows the system to switch between stable enclosed operation and accessible open operation as needed, resolving the contradiction between structural stability and ease of operation.
Solution Approach 2:
The patent extracts the plate from the permanent structure, making it a removable component. This allows the plate to be taken out when access to objects under the housing is needed, while being present when structural stability and beam direction are required. The removable plate design enables the system to have both stability and accessibility at different times without compromise.
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
This configuration enables flexible and precise positioning of the laser beam, accommodating objects of different sizes and shapes by allowing independent adjustments of the laser housing, removable plate, and cart, ensuring accurate and efficient engraving processes.
Implementation Method 1
The galvanometric laser is powered by a photon source and a known system of mirrors for directing photometric energy to the laser and moving and/or redirecting the laser beam according to a digitized program
Implementation Method 2
screw type adjusters mounted on the side panels of the laser housing for changing the height and angle of the laser housing relative to the top plane of a carriage-like support
Implementation Method 3
the laser beam can be projected through the open bottom of the housing, through the open top of the carriage and onto the target object supported by the cart

AI summary
A laser engraver comprises a generally rectangular housing with an open bottom adapted to rest on supports provided at the top plane of an open carriage. Thumb wheel screws operating in fixed nuts on the left and right sides of the laser housing and resting on supports at the top plane of the carriage allow the laser housing can be raised, lower and tilted. A plate can be removably and adjustably mountable within the housing directly under the laser for carrying smaller objects. A cart capable of carrying objects to be engraved can be moved into the space between the carriage side panels and is provided with height and level adjustments to support an object to be engraved by the laser when the removable plate is taken out of the laser housing.
