Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional machines for machining walls, particularly those made of wood or multilayer materials, require auxiliary lateral carriages for overturning, which leads to inefficiencies due to imprecise sliding guides and intersecting rail limitations, resulting in slower and less precise machining processes.
Innovation Solution
A machine design featuring a portal with working heads and a working surface comprising two opposite support and movement frames, equipped with translation and rotation means, allowing for horizontal machining and inclined configurations to facilitate turning over of walls without auxiliary carriages, utilizing chain transmission and linear actuators for precise movement control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If auxiliary lateral carriages are used for overturning walls, then both sides of the wall can be machined, but the machine becomes more complex and less precise due to intersecting guide rails and sliding limitations
Solution Approach 1:
The patent merges the overturning function and the support function into a single integrated frame structure. The first and second frames serve dual purposes: they support the wall during machining and enable overturning through coordinated movement, eliminating the need for separate auxiliary lateral carriages and their complex intersecting guide rail systems
Solution Approach 2:
The frames are designed with multi-functionality, serving as both support structures for the wall and as the overturning mechanism itself. By equipping the frames with translation and rotation means, they can perform multiple operations (supporting, moving, and overturning) without requiring additional dedicated auxiliary devices
2Ease of manufacture
If drawn iron plates are used for guide rails, then the machine structure is simple, but the machining precision and speed are reduced due to slipping and low acceleration
Solution Approach 1:
The patent replaces the traditional mechanical sliding system on drawn iron plates with a chain transmission system. The chains engage with sprockets or teeth on the frames, providing positive engagement that eliminates slipping, ensures precise positioning, and enables controlled acceleration while maintaining structural simplicity
3Adaptability or versatility
If auxiliary carriages with intersecting guide rails are used, then wall overturning is possible, but the overall machine size increases and compactness is reduced
Solution Approach 1:
The patent combines the overturning mechanism within the existing frame structure, eliminating the need for separate auxiliary lateral carriages. The frames themselves perform the overturning function through rotation means, significantly reducing the lateral encumbrances and overall machine footprint while maintaining the capability to overturn walls
4Device complexity
If conventional sliding guides are used, then the machine structure is straightforward, but the machining speed is limited due to low acceleration and slipping
Solution Approach 1:
The patent substitutes the sliding friction-based movement system with a chain-driven positive engagement system. The chains transmit motion through sprocket engagement, eliminating slipping and enabling higher acceleration rates and machining speeds while keeping the overall system architecture relatively simple
