Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing droplet discharge technologies face challenges in accurately placing droplets into droplet storage parts without causing the discharge part to collide with the storage vessel.
Innovation Solution
A droplet discharge device with a droplet discharge part, a detecting part, a holding part, and a mover part, which collectively move relative to the storage vessel to accurately position the droplet discharge tip within the storage vessel's recessed droplet storage parts, using sensors to detect the vessel's shape and a controller to control the movement and discharge process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the droplet discharge part is moved close to the storage vessel for accurate droplet placement, then droplet placement accuracy is improved, but the risk of collision between the discharge part and vessel surface increases
Solution Approach 1:
The detecting part performs shape detection of the storage vessel surface before the droplet discharge operation begins. This preliminary detection allows the system to acquire surface shape data and determine safe discharge positions in advance, enabling the droplet discharge part to be positioned accurately without colliding with the vessel surface.
Solution Approach 2:
The system uses the detecting part to continuously monitor the shape of the storage vessel surface and feeds this information back to the control part. Based on this feedback, the control part adjusts the position of the droplet discharge part in real-time, ensuring accurate droplet placement while avoiding collision with the vessel surface.
2Adaptability or versatility
If the detecting part is used to detect the shape of the storage vessel, then adaptability to varying vessel specifications is improved, but device complexity increases
Solution Approach 1:
The detecting part is designed with multi-functionality, serving both to detect the shape of the storage vessel surface and to provide position information for droplet discharge. This universal component reduces the need for separate detection and discharge systems, thereby limiting the increase in device complexity while maintaining high adaptability to various vessel specifications.
