Vacuum Vibration Press for Engineered Stone Slabs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for manufacturing engineered stone slabs, such as the Breton vacuum vibration press, are costly, energy-inefficient, and require significant vibrational energy transmission, leading to high resin usage and prolonged production times, while also imposing structural vibrations and high operational costs.
Innovation Solution
A lightweight vacuum vibration press design that applies vibrational energy from both above and below the slab, eliminating the need for a massive inertial base, reducing resin requirements, and optimizing energy transfer for faster production cycles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional Breton vacuum vibration press is used to manufacture engineered stone slabs, then the slab quality can be achieved, but the apparatus weight is extremely high (350+ tons inertial base) and installation cost is prohibitive
Solution Approach 1:
The patent extracts and eliminates the massive inertial base (350+ tons) from the conventional Breton press design. Instead of using a heavy stationary base to generate vibrations, the invention uses a lightweight press plate that can be vibrated directly, removing the unnecessary mass while maintaining the essential vibration function for slab production
Solution Approach 2:
The patent inverts the traditional approach by applying vibrations from both above and below the press plate simultaneously. Rather than relying on a heavy base to generate vibrations from one direction, the system uses opposing vibration sources that work together to achieve the same compaction effect with minimal mass
2Reliability
If conventional Breton press design is used, then slab formation is achieved, but energy consumption is high and production time is prolonged
Solution Approach 1:
The patent employs periodic vibration cycles applied from both above and below the press plate, creating efficient compaction rhythms that achieve slab formation faster than continuous single-direction vibration. The alternating vibration patterns optimize energy transfer to the slab material
Solution Approach 2:
The system maintains continuous effective vibration action on the slab throughout the pressing cycle by coordinating upper and lower vibration sources. This ensures that useful compaction energy is applied continuously without interruption or waste, shortening production time while reducing total energy consumption
3Reliability
If conventional Breton press is used, then engineered stone slabs can be produced, but structural vibrations are imposed on surrounding infrastructure
Solution Approach 1:
The patent converts what would normally be harmful vibrations into a beneficial controlled process by applying vibrations from both directions simultaneously. The opposing vibration sources create internal cancellation effects that contain the vibrational energy within the press plate and slab, preventing transmission to surrounding infrastructure while maintaining effective compaction
4Manufacturing precision
If conventional Breton press design is used, then slab compaction is achieved, but resin usage is high due to insufficient vibration efficiency
Solution Approach 1:
The patent uses intense mechanical vibrations applied from both above and below the press plate to achieve thorough slab compaction. This efficient vibration method properly consolidates the stone aggregate and eliminates voids, allowing the resin binder to work effectively at lower concentrations rather than requiring excess resin to compensate for poor compaction
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The new press achieves equivalent or superior slab quality with reduced resin usage, shorter production times, lower energy consumption, and minimal structural vibrations, while significantly lowering the apparatus' weight and installation costs.
Implementation Method 1
a first vibration device attached to a bottom of the vibration table, and a second vibration device attached to a top of the pressing mechanism. The pressing mechanism and the vibration devices are configured to apply compressional and vibrational forces to the slab
Implementation Method 2
A vacuum vibration press for making engineered stone slabs applies as much or more CPE energy to a formed ES-BS slab mixture as a conventional Breton press

AI summary
A vacuum vibration press manufactures engineered stone slabs that are equal or superior in appearance and physical properties to slabs manufactured using a conventional Breton press, while weighing less, costing less to manufacture, providing shorter press cycle times, requiring less resin, and consuming less energy. In addition to providing a vibration device above the slab, the press also includes a second vibration device below the slab, which replaces the massive inertial base of a Breton press. The vibration devices can have different frequencies, amplitudes, and/or vibration axes. The press can be completely enclosed within a vacuum chamber, and vibrationally isolated from surrounding structures. In embodiments, volume reduction blocks reduce the volume to be evacuated. Embodiments use screw jacks and springs or air bags to provide controlled pressing force and precisely uniform slab thickness. Slabs can be inserted and removed on a conveyor belt, or in separate trays on rollers.
