Ceramic Press Structure with Polycentric Cuts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ceramic tile-forming presses have large, complex structures that are inefficient in terms of size and assembly, with high resistance to fatigue and stability issues due to the need for extensive support and modular components, leading to increased production costs and potential deformation under load.
Innovation Solution
A compact, lightweight press structure featuring monolithic annular elements with specific full-thickness cuts and lubricated surfaces, allowing for modular assembly and distribution of load stresses, reducing the overall size and weight while maintaining resistance to fatigue and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a large free space between uprights is provided to accommodate large pressing rectangles, then the inlet mouth for material is sufficient, but the structure becomes excessively large and tall requiring partial interment
Solution Approach 1:
The patent reorients the structural support from a vertical configuration (tall uprights) to a horizontal configuration (longitudinal beams along the inlet direction). This dimensional change allows the pressing force to be supported along the length of the press rather than requiring height, thus resolving the contradiction between providing sufficient free space and avoiding excessive structure height
2Strength
If thick uprights are used to guarantee undeformability under pressing force, then structural stability is improved, but the structure becomes excessively tall and complex
Solution Approach 1:
The patent divides the structural support into multiple longitudinal beams distributed along the inlet direction, rather than using a single thick upright. Each beam carries a portion of the pressing force, and their collective arrangement provides the necessary structural stability while maintaining a simpler, more compact overall structure
Solution Approach 2:
The support structure is reconfigured from vertical uprights to horizontal longitudinal beams, changing the dimension in which structural strength is provided. This allows the press to achieve the required resistance to pressing force through the length of the beams rather than through vertical height, simplifying the overall device complexity
3Adaptability or versatility
If a modular structure with multiple resistant elements is used to adapt to loading defects, then flexibility is improved, but the assembly complexity increases
Solution Approach 1:
The press structure is divided into multiple modular pressing units, each with its own resistant elements, arranged in series along the inlet direction. This segmentation allows individual modules to be adjusted or replaced independently to adapt to loading defects, while the modular nature simplifies assembly compared to a monolithic complex structure

AI summary
A structure for presses, a resistant structure of which includes at least a resistant element which, in turn, includes an annular element or arch, internally of which are predisposed two facing surfaces, between which at least a power organ is insertable, which power organ is suitable for compressing an object or material to be pressed between two bodies. Full-thickness cuts are symmetrically arranged at ends of the facing surfaces, each cut, starting from the end of the relative facing surface, develops over an arc of a polycentric curve which exhibits at least a first tract, the most external surface of which connects with the lateral surface of the vertical portion of the annular element or arch, and at least a second tract which is connected to the first tract and extends over a portion of not less than a quarter of an arc of circumference.
