Painting System Shared Cleaning Tank
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional painting systems require multiple cleaning tanks for each painting robot, leading to increased parts count, production time, and equipment costs due to the individual configuration of painting robots.
Innovation Solution
A painting system with a single cleaning tank and a cartridge carrier that can handle both painting robots, allowing for overlapping movable regions to reduce the number of parts and streamline the paint cartridge replacement process, enabling efficient cleaning and reduced equipment costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If each painting robot is provided with an individual cleaning tank, then each robot can independently clean its spray gun, but the number of parts count increases and equipment cost rises
Solution Approach 1:
The patent merges the cleaning function from individual robot units into a centralized cleaning tank that serves multiple painting robots. The cleaning tank is positioned in a region accessible to multiple robots, allowing them to share the same cleaning resource rather than each having dedicated cleaning equipment.
Solution Approach 2:
The cleaning tank is designed as a universal facility that can serve multiple painting robots simultaneously or sequentially. By positioning it in an overlapping movable region, the system enables any painting robot to access the same cleaning tank for maintaining their spray guns, reducing overall system complexity.
2Productivity
If each painting robot has its own cleaning tank, then cleaning can be performed independently, but production time and assembly time increase
Solution Approach 1:
Multiple painting robots share a common cleaning tank, which reduces the total number of cleaning operations needed during system assembly and setup. This shared resource approach decreases the time required to install and configure the painting system while maintaining cleaning effectiveness.
3Adaptability or versatility
If painting robots are configured as individual units with dedicated cleaning tanks, then each robot is self-sufficient, but the painting system becomes more complex and expensive
Solution Approach 1:
The cleaning tank is designed as a universal facility that multiple painting robots can access. This universal approach maintains the functional independence of each robot while reducing system complexity by eliminating redundant cleaning tanks. The robots retain their self-sufficiency in terms of cleaning capability, but share the underlying infrastructure.

AI summary
A painting system includes painting unit including a first painting robot and a second painting robot, a cartridge carrier, and a cleaning tank. The painting robots each include a robot arm including a painting machine. The cartridge carrier includes a cartridge grip part. A first region is a region where a movable region of the painting machine of the first painting robot overlaps with a movable region of the cartridge grip part. A second region is a region where the movable region of the painting machine of the second painting robot overlaps with the movable region of the cartridge grip part. The cleaning tank is provided in a position including at least a part of the first region and at least a part of the second region.
