Gluing Device for Brick Slips with Controlled Dispensing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing gluing devices for brick slips and stone slips are time-consuming and costly due to the excessive use of glue, which is often cement-based and has a short open time, making it difficult to achieve full surface bonding before hardening.
Innovation Solution
A gluing device with a removable glue container, a discharge nozzle for precise glue application, and a plunger mechanism that allows for controlled dispensing of cement-based glue directly onto the brick slip, ensuring full surface bonding within the limited open time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If glue is applied in a layer or continuous line on the entire base surface, then automated processing speed is improved, but glue consumption increases and cement-based glue cannot be used effectively
Solution Approach 1:
The patent applies glue locally at the discharge nozzle directly onto the brick slip surface rather than covering the entire base surface. This localized application method reduces glue consumption while maintaining automated processing efficiency, as glue is only applied where needed for bonding.
Solution Approach 2:
Instead of applying glue to the base surface and then placing the brick slip (conventional method), the patent inverts the process by applying glue directly onto the brick slip at the discharge nozzle before placement. This inversion enables precise control of glue application and allows use of cement-based glue with short open time.
2Strength
If cement-based glue is used for full surface bonding, then bonding strength and water resistance are improved, but processing time is reduced due to rapid hardening
Solution Approach 1:
The patent applies glue to the brick slip in advance at the discharge nozzle, just before placement on the base surface. This preliminary action ensures the glue is applied at the optimal moment within the short open time of cement-based glue, allowing full surface bonding strength to be achieved without wasting processing time.
Solution Approach 2:
The patent rushes through the glue application process by applying cement-based glue directly onto the brick slip immediately before placement, completing the bonding action within the very limited open time window. This eliminates delays and ensures the glue remains processable throughout the critical bonding phase.
3Duration of action of moving object
If paste-based glue is used to allow longer processing time, then processing flexibility is improved, but bonding strength and water resistance are reduced
Solution Approach 1:
The patent changes the application parameters of cement-based glue by applying it locally and directly onto the brick slip rather than spreading it over the base surface. This parameter change allows cement-based glue (normally restricted to very short processing time) to be used effectively, achieving both strong bonding and adequate processing time for automated application.
