Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current devices for dispensing granular or powdered materials for ceramic tile decoration lack precision in material deposition and positioning, resulting in imprecise shading or veining effects.
Innovation Solution
A dispensing bar with a dispensing channel and suction means that uses negative pressure to block the flow of material, allowing precise control through the activation and deactivation of suction and blowing means, ensuring accurate deposition without compressing or squeezing the material.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If gravity-based dispensing devices are used to deposit granular material, then the device structure is simple, but the precision of material deposition and positioning is poor
Solution Approach 1:
The patent replaces traditional mechanical closure means with a pneumatic system. A dispensing channel with controlled openings uses air pressure to regulate material flow, eliminating complex mechanical moving parts while achieving precise deposition control through pressure regulation.
Solution Approach 2:
The invention employs pneumatic pressure control through a dispensing channel with regulated openings. By controlling air pressure applied to the granular material, the system achieves precise control over material flow and deposition position without requiring complex mechanical actuation mechanisms.
2Manufacturing precision
If complex closure means are used to control material release, then positioning precision may improve, but the device becomes more complex and harder to operate
Solution Approach 1:
Complex mechanical closure means are replaced with a pneumatic control system. The dispensing channel uses regulated air pressure to control material release, simplifying operation to pressure regulation while maintaining precise positioning through controlled opening mechanisms.
3Manufacturing precision
If traditional dispensing devices are used, then the structure is relatively simple, but the amount and position of material deposited cannot be precisely controlled
Solution Approach 1:
The patent uses a dispensing channel with pressure-regulated openings to control both the amount and position of material deposited. Pneumatic pressure control allows independent regulation of flow rate and deposition location, achieving precise control without proportionally increasing structural complexity.
Solution Approach 2:
The system controls material deposition by changing pressure parameters. By regulating air pressure applied to the granular material in the dispensing channel, the system can precisely control both the quantity of material released and its deposition position, transforming a mechanical control problem into a pressure parameter control problem.

Function Achieved in This Case
Enables precise and controlled deposition of materials, such as atomized ceramic, allowing for intricate designs and efficient application, suitable for high-volume use with minimal mechanical complexity and compact size.
Implementation Method 1
suction means, arranged to retain at least a part of the product inside the dispensing channel (2a), so as to form an accumulation which obstructs the dispensing channel (2a) and prevents the flow of the product
Implementation Method 2
the longitudinal axis has an inclination such as to allow the product to flow by gravity from the inlet opening (21) to the outlet opening (22)
