Solution Overview
Problem
Existing machines for machining panel edges, particularly those made of wood, risk damaging the surfaces due to excessive friction from copying devices during the machining process, and they are complex, inefficient, and lack precision.
Innovation Solution
A machine equipped with a cutting member, a detecting device that is idly rotatable and connected to a braking system with friction elements above and below the panel, allowing the detecting device to decelerate through controlled friction, reducing surface damage and improving efficiency and precision.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the copying device rotates excessively on the panel to detect the shape, then the detection function is improved, but the panel surface is damaged due to friction
Solution Approach 1:
A friction element is introduced as an intermediary between the copying device and the panel surface. The copying device contacts the friction element instead of directly contacting the panel, allowing rotation detection while the friction element absorbs the harmful friction effects through controlled friction between the copying device and the friction element itself.
Solution Approach 2:
The harmful friction function is extracted from the panel surface and transferred to a separate friction element. The friction element is positioned above and below the panel plane, separating the detection function from the panel surface interaction, thereby protecting the panel while maintaining detection capability.
2Object-affected harmful factors
If the copying device is made stationary or less rotatable to protect the panel surface, then surface damage is reduced, but the detection precision and efficiency deteriorate
Solution Approach 1:
The friction element serves as a mediator that enables the copying device to rotate freely for accurate detection while preventing direct excessive friction on the panel. The controlled friction between the copying device and friction element allows necessary rotation without damaging the panel surface.
3Object-affected harmful factors
If a braking system with friction elements is added to control copying device rotation, then surface damage is reduced, but the device complexity increases
Solution Approach 1:
The friction element serves multiple functions simultaneously: it acts as a braking element to control rotation speed, a protective element to prevent panel damage, and a reference element for the copying device to detect panel shape. This multi-functionality reduces the need for separate components, thereby limiting the increase in device complexity.
4Adaptability or versatility
If the detecting device is moved frequently between positions to machine different edges, then machining versatility is improved, but the execution time increases
Solution Approach 1:
The friction elements are pre-positioned above and below the panel plane at strategic locations. This preliminary positioning allows the copying device to quickly move between different edge machining positions without needing to search for or adjust friction contact points during operation, thereby reducing execution time while maintaining versatility.
