Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for machine gluing stone strips to substrates face challenges in achieving consistent adhesion quality and speed, particularly with varying strip dimensions and complex bonding patterns, leading to potential gaps or excessive joint thicknesses and inadequate bonding strength.
Innovation Solution
A method where the contact pressure is dynamically determined based on the delay time and glue temperature, allowing for variable contact pressures and times to optimize adhesion, with a device equipped to apply glue and pressure units controlled by a unit that adjusts settings for each stone strip based on its properties and substrate conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If constant contact pressure and contact time are used during machine gluing, then the manufacturing process is simple and fast, but the adhesion quality cannot be guaranteed due to varying strip dimensions and glue conditions
Solution Approach 1:
The patent implements dynamic adjustment of contact pressure and contact time parameters during the gluing process. The contact pressure is varied based on the delay time between glue application and strip placement, allowing the system to adapt to different glue conditions and strip dimensions rather than using fixed constant values throughout the process
Solution Approach 2:
The patent changes the parameters of contact pressure and contact time based on the delay time variable. By adjusting these parameters dynamically according to when the strip is placed relative to glue application, the system optimizes adhesion quality for varying conditions without requiring completely complex new equipment
2Productivity
If the production speed is increased by reducing contact time, then productivity improves, but adhesion quality deteriorates
Solution Approach 1:
The patent establishes specific relationships between contact time and delay time parameters. By defining contact time ranges (0.005-1 second) that correlate with delay time, the system maintains adequate adhesion quality while enabling faster production cycles compared to traditional constant long contact times
3Strength
If the contact pressure is increased to ensure adhesion, then bonding strength improves, but energy consumption increases and production speed decreases
Solution Approach 1:
The patent varies contact pressure based on delay time rather than applying uniformly high pressure. By adjusting pressure levels according to when strips are placed relative to glue application, the system achieves sufficient bonding strength while minimizing unnecessary energy consumption from excessive pressure application
Solution Approach 2:
The patent applies contact pressure selectively and partially - using higher pressure only when needed based on delay time conditions, and lower pressure when conditions allow. This avoids the excessive energy consumption of applying high pressure universally to all strips regardless of actual adhesion requirements

AI summary
Method and device for machine gluing stone strips to a substrate, wherein glue is applied to the substrate and/or the stone strips, wherein subsequently, after a delay time, the stone strips are each pressed against the substrate with the glue between the stone strips and the substrate, during a contact time and with a contact pressure, wherein the contact pressure is determined as a function of the delay time between the glue being applied and the stone strip being pressed, and optionally also as a function of the glue temperature.
