Problem
Existing linear positioners used in construction and carpentry are often non-portable, costly, complex, and difficult to assemble and maintain, making them less attractive for frequent use at different job sites.
Innovation Solution
A portable and user-friendly linear positioner system that includes a carriage driven along a track by a motor, controlled via radiofrequency signals from a handheld computer, featuring a rack with linear teeth and interchangeable table sections for adjustable length and easy assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a linear positioner is designed to be portable and easy to assemble, then ease of operation and portability are improved, but positioning precision and structural stability may deteriorate
Solution Approach 1:
The linear positioner is divided into multiple modular components including a base assembly, a carriage assembly, and a fence assembly that can be easily assembled and disassembled. The rack is segmented into multiple sections that can be connected together to achieve different lengths, facilitating portability and ease of setup while maintaining precision through standardized connection interfaces
Solution Approach 2:
The patent replaces complex mechanical positioning mechanisms with a simplified system using a motorized carriage that travels along a rack. The positioning is achieved through electronic control and feedback mechanisms rather than purely mechanical adjustments, reducing assembly complexity while maintaining precision
2Volume of moving object
If a linear positioner is designed to be compact and portable, then portability is improved, but the measurement range and functionality may deteriorate
Solution Approach 1:
The rack is designed as a segmented structure with multiple connectable sections. When maximum measurement range is needed, additional rack sections can be attached to extend the travel distance of the carriage. When portability is the priority, the rack can be configured with fewer sections or completely disassembled for transport
Solution Approach 2:
The linear positioner features an adjustable and reconfigurable structure where the fence height and rack length can be modified based on the specific work requirements. This dynamic adaptability allows the same compact device to serve multiple measurement and cutting applications
3Productivity
If a linear positioner uses automated control systems, then productivity and precision are improved, but device complexity and cost increase
Solution Approach 1:
The patent incorporates a motorized carriage with electronic control that replaces manual positioning mechanisms. The system uses a simple electronic interface with memory functions to store and recall cutting positions, providing automated control without requiring complex programming or control systems. This balance achieves improved productivity while keeping the system relatively simple and cost-effective

AI summary
Systems, methods, and apparatus for positioning and/or processing items, such as workpieces. The systems, methods, and apparatus may include or use a linear positioner forming a track. In some embodiments, the linear positioner may include a carriage configured to be driven along the track to a desired position, in response to a signal(s), such as a radiofrequency signal(s), received from a computer, which may be a general-purpose, handheld computer, such as a phone or tablet. In some embodiments, the linear positioner may comprise a shuttle including a motor and a carriage, and may be configured to drive itself as a unit along the track. In some embodiments, the track may include a rack having a linear array of teeth formed by two or more frame sections, such as table sections, coupled end to end, with each support section providing a segment of the rack.
