Motorized Layout Pointer With Dual-Axis Beam Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing motorized layout pointers are limited to indicating layout points on a jobsite surface that is a floor and require placement near the layout point, unable to efficiently indicate points on walls or ceilings.
Innovation Solution
A motorized layout pointer with a rotatable layouting beam about two axes of rotation, equipped with motors and gimbals, allows indication on any jobsite surface, including floors, walls, and ceilings, and includes sensors for accurate orientation and distance measurement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the layouting beam is fixed in direction, then the device structure is simple, but the device can only indicate layout points on floor surfaces near the device
Solution Approach 1:
The layouting beam is made dynamically adjustable through motorized rotation mechanisms. The first rotation mechanism allows the beam to rotate about a first axis, and the second rotation mechanism allows rotation about a second axis perpendicular to the first. This dynamic positioning capability enables the beam to indicate layout points on various surfaces (floor, wall, ceiling) from a single device location, resolving the contradiction between versatility and structural complexity.
Solution Approach 2:
The invention adds rotational degrees of freedom in multiple dimensions. By introducing rotation about two perpendicular axes, the layouting beam can orient in three-dimensional space, transforming from a fixed-direction indicator to a multi-directional indicator capable of reaching any surface orientation around the device.
2Adaptability or versatility
If the layout pointer is placed in the vicinity of the layout point, then the indication is simple, but the device cannot indicate points on walls or ceilings
Solution Approach 1:
The motorized rotation mechanisms enable the layouting beam to dynamically adjust its direction without moving the entire device. The first motor rotates the beam about the first axis, and the second motor rotates it about the second axis, allowing the beam to reach any surface (floor, wall, ceiling) from a centralized device location, eliminating the need to place the device near each layout point.
Solution Approach 2:
The rotatable layouting beam acts as an intermediary that extends the device's reach. Instead of moving the entire device to different locations, the beam rotates to intermediate positions, allowing indication on various surfaces while the device remains stationary at a convenient location.
3Productivity
If manual positioning is used, then the device structure is simple, but the indication speed and precision are limited
Solution Approach 1:
The motorized rotation mechanisms enable the layouting beam to automatically position itself according to control signals. The system can autonomously adjust the beam's orientation to indicate layout points, eliminating the need for manual repositioning and significantly improving indication speed and precision while maintaining systematic control.
Solution Approach 2:
Manual mechanical positioning is replaced with motorized actuation. The first motor and second motor provide automated rotational control, substituting human operation with electromechanical systems that offer faster, more precise, and repeatable positioning capabilities.
