Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional manual tile engravers face challenges in processing large slabs due to the need for heavy and costly fixing systems, which complicate use and risk scratching the tiles, while existing alternatives are less convenient and inefficient.
Innovation Solution
An engraving/cutting machine with a rectilinear bar featuring high-friction yielding supports and a pivoting pressure plate with elastic means, eliminating the need for traditional suction cups or clamps by utilizing rubber inserts and torsional springs to create a stable friction surface for precise engraving.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional suction cups or clamps are used to fix the guiding bar to the slab, then engraving precision is ensured, but the device becomes heavy, costly, and complex
Solution Approach 1:
The invention extracts and eliminates the traditional fixing systems (suction cups and clamps) from the guiding bar structure. Instead of attaching the guiding bar to the slab, the system allows the bar to rest freely on the slab surface, removing the complex fixing apparatus entirely while maintaining engraving precision through the friction-based positioning mechanism.
Solution Approach 2:
The invention introduces yielding support means made of high-friction material as an intermediary between the guiding bar and the slab. This intermediary layer provides sufficient friction to prevent relative movement and ensure engraving precision without requiring mechanical fixing devices, thus simplifying the overall system.
2Stability of the object's composition
If traditional suction cups or clamps are used to fix the guiding bar, then stability is improved, but the device weight and cost increase
Solution Approach 1:
The invention removes the heavy fixing systems (suction cups and clamps) from the guiding bar assembly. The guiding bar and carriage system can now be made lightweight without compromising stability, as the high-friction yielding supports provide sufficient stabilization without additional weight.
Solution Approach 2:
The invention changes the friction parameter by using yielding support means made of high-friction material. This parameter change allows the lightweight guiding bar to achieve stable positioning on the slab through friction alone, eliminating the need for heavy mechanical fixing devices.
3Stability of the object's composition
If the guiding bar is pressed strongly against the slab by fixing clamps, then relative movement is prevented, but the slab surface may be scratched or damaged
Solution Approach 1:
The invention places a layer of yielding support means made of soft, high-friction material between the guiding bar and the slab surface before operation begins. This cushioning layer prevents direct contact between hard metal surfaces, eliminating scratching and damage while maintaining position stability through friction.
Solution Approach 2:
The yielding support material serves as an intermediary between the guiding bar and the slab, providing a protective interface that prevents surface damage. This intermediary layer transmits frictional forces to prevent relative movement without concentrating stress points that could scratch or damage the slab surface.
4Manufacturing precision
If fixing devices are added to the guiding bar system, then engraving precision is maintained, but the device becomes less convenient to use
Solution Approach 1:
The invention extracts and removes all fixing devices from the system. The guiding bar and carriage can be freely positioned and adjusted on the slab without clamps or suction cups, making the device much more convenient to set up and operate while maintaining precision through the high-friction support mechanism.
