Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional woodworking tenoning machines require users to manually calculate and input multiple specifications for different tenon shapes, widths, and thicknesses, leading to a cumbersome and inaccurate process when changing shapes, widths, and thicknesses.
Innovation Solution
A working control module with a human machine interface (HMI) that allows users to select and input characteristic variables for a desired tenon shape, generating a 3D model and automating the working process through a tool selection, model calculation, 3D drawing, working path, feeding, and material returning modules.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional woodworking tenoning machine is used to change different shapes, widths, and thicknesses of wood materials, then the machine can process various wood specifications, but the user has to manually calculate and input multiple specification values which makes the working process troublesome and reduces working accuracy
Solution Approach 1:
The patent uses a camera to capture images of the wood material and employs image recognition technology to automatically identify and copy the wood's shape, width, and thickness parameters. This eliminates the need for manual measurement and input, directly resolving the contradiction by maintaining versatility while dramatically improving ease of operation
Solution Approach 2:
The system enables the woodworking machine to automatically determine its own processing parameters by using the camera and image recognition module to self-identify the wood material specifications. The machine serves itself by automatically setting the working parameters without human intervention, thus improving ease of operation while maintaining adaptability
2Manufacturing precision
If the user manually inputs characteristic variables of the desired tenon shape, then the machine can calculate multiple specification values, but the working result cannot be learned in advance and the process is time-consuming
Solution Approach 1:
The patent implements a preview function that displays the expected tenon shape and working results before actual processing. The image recognition module pre-calculates all specification values and presents them to the user for confirmation, allowing the user to review and approve the results in advance. This eliminates the need for iterative manual input and calculation, significantly reducing time loss while maintaining manufacturing precision
Solution Approach 2:
The patent replaces the manual mechanical process of inputting and calculating specification values with an automated image recognition and computer vision system. The camera captures the wood material, the system automatically calculates all tenon parameters, and displays the results for preview, substituting manual operations with automated technological processes to reduce time consumption while maintaining precision
3Productivity
If the conventional machine requires repeated manual input for each new wood specification, then the machine can maintain simple control structure, but the working efficiency is reduced due to the troublesome working process
Solution Approach 1:
The patent integrates multiple functions into a unified control system that combines camera imaging, image recognition, parameter calculation, and machine control. The control module serves multiple purposes: capturing wood specifications, identifying parameters, calculating tenon dimensions, and controlling the processing operation. This multi-functionality improves productivity by eliminating repetitive manual operations while the integrated design keeps the overall system complexity manageable

AI summary
A working control module of a woodworking tenoning machine is configured to work a wood material in a desired tenoning shape by using a human machine interface (HMI). The working control module contains: a tool selection module, a tenoning shape selection module, a model calculation module, a three-dimensional (3D) drawing module, a working path module, a feeding module, a working module, and a material returning module. Thereby, the user is capable of selecting the desired tenon shape, inputting the at least one characteristic variable of the desired tenon shape to draw, view or amend the 3D model by using the HMI of the working control module. After confirming the 3D model, the wood material is worked in the desired tenon shape automatically, thus enhancing working efficiency and working accuracy.
