Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing robot tools for dispensing anticorrosion wax on motor vehicle body parts are inefficient for both narrow line and planar applications, requiring either separate tools or lengthy cycle times due to their inability to switch between non-atomized and atomized delivery modes effectively.
Innovation Solution
A robot tool with a dual-nozzle unit that can switch between delivering anticorrosion wax as a non-atomized jet and an atomized spray cone by controlling the supply of compressed air, allowing for flexible and efficient application on both linear and planar surfaces without the need for tool changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a robot tool uses non-atomized delivery of anticorrosion wax in the form of narrow lines, then the application precision is improved, but the productivity deteriorates because it is time-consuming to fill large areas
Solution Approach 1:
The robot tool incorporates a switchable nozzle unit that can dynamically change between non-atomized delivery mode (for narrow lines with high precision) and atomized delivery mode (for large areas with high productivity). This dynamic adaptability allows the system to optimize for precision or productivity depending on the specific application requirements without compromising either capability
Solution Approach 2:
The nozzle unit is designed with dual functionality, integrating both non-atomized and atomized delivery capabilities within a single device. The internal nozzle provides non-atomized delivery while the external nozzle provides atomized delivery, allowing the robot tool to handle both precision line applications and large-area coatings without requiring tool changes
2Productivity
If a robot tool is configured for atomized delivery of anticorrosion wax, then the productivity is improved for planar application, but the ability to deliver narrow lines deteriorates
Solution Approach 1:
The switchable nozzle configuration enables the system to dynamically adapt its delivery mode. When atomized delivery is activated for planar surfaces, productivity increases. When non-atomized delivery is activated for narrow lines, precision is restored. This dynamic switching resolves the contradiction by allowing the system to optimize for the specific task at hand
Solution Approach 2:
The dual-nozzle design provides universal capability for both atomized and non-atomized delivery within a single tool. The internal nozzle maintains narrow line delivery capability while the external nozzle enables atomized planar application, making the robot tool universally suitable for both application types without sacrificing either productivity or precision
3Manufacturing precision
If separate robot tools are used for line-shaped and planar application, then the manufacturing precision for each mode is improved, but the device complexity increases due to tool changes
Solution Approach 1:
The invention merges the functionality of two separate robot tools (one for non-atomized line delivery, one for atomized planar delivery) into a single integrated nozzle unit. The internal and external nozzles are combined in a switchable configuration, eliminating the need for tool changes while maintaining the precision benefits of both specialized tools
Solution Approach 2:
By integrating both non-atomized and atomized delivery capabilities into one universal nozzle unit, the system eliminates device complexity associated with multiple tools and changes. The switchable configuration allows the single tool to perform both functions with equal precision, reducing overall system complexity while maintaining high manufacturing precision
4Manufacturing precision
If tool changes are required between line-shaped and planar application, then the manufacturing precision for each mode is maintained, but the loss of time increases due to tool changes
Solution Approach 1:
Both non-atomized and atomized delivery capabilities are prepared in advance within the single switchable nozzle unit. The internal and external nozzles are pre-configured and ready for immediate switching without requiring tool changes. This preliminary preparation of both delivery modes in one tool eliminates time loss during transitions while maintaining precision
Solution Approach 2:
The switchable nozzle unit enables rapid dynamic switching between non-atomized and atomized delivery modes without physical tool changes. This dynamic capability allows the system to maintain high manufacturing precision for both application types while dramatically reducing the time loss that would otherwise occur during tool changes, thereby shortening overall cycle time

Implementation Method 1
the internal nozzle in the delivery direction is aligned so as to be flush with the external nozzle such that, when the atomizing chamber is not supplied with compressed air, anticorrosion wax which exits in the form of a jet by way of the internal nozzle may be delivered as a jet through the atomizing chamber and through the external nozzle
Implementation Method 2
The atomizing chamber, when the atomizing chamber is supplied with compressed air, is configured for atomizing the jet exiting from the internal nozzle by way of the supplied compressed air
Implementation Method 3
the supply duct for the compressed air opens into the atomizing chamber

AI summary
A robot tool for dispensing an anticorrosion wax including a nozzle unit for delivering non-atomized wax as a thin jet and wax atomized with compressed air as a spray cone. The nozzle unit is connected to a supply duct for compressed air and to a supply duct for wax, and has an internal nozzle for producing the jet and an external nozzle for producing the spray cone. An atomizing chamber is between the internal nozzle and the external nozzle, wherein the supply duct opens into the atomizing chamber. The internal nozzle is flush with the external nozzle such that, when the atomizing chamber is not supplied with compressed air, wax which exits as the jet may be delivered through the atomizing chamber and through the external nozzle. The atomizing chamber when supplied with compressed air is configured for atomizing the jet exiting from the internal nozzle by the compressed air.
