Portable Master-Piece Duplicating Machine with Movable Cart
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Prior art master-piece duplicating machines are cumbersome and inconvenient for use at job sites due to their stationary nature, making it difficult to create precise joints between profiles at corners of walls.
Innovation Solution
A machining device with a movable cart and rail system that allows manual sliding along a rail, secured to a table saw, enabling the cutting blade to duplicate the master-piece by securing both the master-piece and work-piece with vices and using a limiting element to control the sliding motion, allowing for precise cutting and profile coping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the master-piece duplicating machine is made stationary with a fixed cart and rail system, then the manufacturing precision and stability are improved, but the ease of operation and portability deteriorate
Solution Approach 1:
The cart and rail system is designed to be movable rather than fixed, allowing the entire duplicating machine to be transported to different job sites while maintaining manufacturing precision through the controlled sliding mechanism along the rail
Solution Approach 2:
The machine is divided into separable components including the cart, rail, vices, and limiting element, allowing for easy assembly and disassembly for transport while maintaining functional integrity during operation
2Stability of the object's composition
If the cart and work-piece are made stationary, then the stability is improved, but the productivity and adaptability deteriorate
Solution Approach 1:
The cutting blade is made movable relative to the stationary cart and work-piece, allowing the blade to slide along the rail to perform cutting operations while the work-piece remains stable and properly positioned throughout the process
Solution Approach 2:
The rail serves as an intermediary element that allows the cutting blade to move precisely along a defined path while the cart and work-piece remain stationary, enabling efficient cutting without compromising stability
3Manufacturing precision
If the machine is designed as a stationary carpentry shop equipment, then the manufacturing precision is improved, but the adaptability to different locations deteriorates
Solution Approach 1:
The entire duplicating machine including cart and rail is designed to be movable, transitioning from a stationary shop equipment to a portable job site tool while maintaining precision through the controlled sliding mechanism
Solution Approach 2:
The machine is designed to be universally applicable at various job sites for different profiling and cutting tasks, combining the precision of stationary equipment with the flexibility of portable operation

AI summary
A machining device, including: a cart, for carrying a master-piece and a work-piece; a rail, for allowing manual sliding of the cart along the rail thereabove; a first vice for securing the master-piece, the first vice being fixed to the movable cart; a second vice for securing the work-piece, the second vice being fixed to the movable cart; a limiting element, for limiting the manual sliding of the cart upon meeting of the master-piece with the limiting element; and a protrusion including at least two points extending downwards from the rail; thereby the machining device utilizes parallelism between the channel and a cutting blade of the table saw.
