Solution Overview
Problem
Conventional discharge amount control devices fail to accurately apply fluids with high viscosity along target application tracks due to the fluid's behavior after discharge, leading to deviations from the intended application path.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional discharge amount control devices are used to control fluid discharge based on application speed detection, then the discharge amount can be controlled, but the fluid application track deviates from the target track due to fluid viscosity behavior
Solution Approach 1:
The system performs preliminary track generation by calculating the expected fluid application track based on the nozzle track and fluid viscosity characteristics before actual fluid discharge occurs. This allows the control system to anticipate and compensate for fluid behavior deviations, ensuring the fluid applies along the correct target track rather than following the nozzle path directly.
Solution Approach 2:
The system detects the actual fluid application track and compares it with the target track, using this feedback information to adjust the discharge amount control. The detected deviation is fed back to the control unit which modifies the discharge rate dynamically to correct track deviations caused by fluid viscosity.
2Adaptability or versatility
If the fluid discharge unit moves along a curved track, then the application area can be covered, but the fluid application track deviates from the curved target track due to fluid inertia and viscosity
Solution Approach 1:
Before the fluid discharge unit follows a curved track, the system pre-calculates the expected fluid application path by inputting the curved nozzle track and fluid viscosity parameters into the track generation unit. This allows the system to anticipate the fluid's curved behavior and adjust the nozzle movement accordingly to maintain accurate alignment with the target curved track.
Solution Approach 2:
The system dynamically adjusts the discharge amount based on real-time detection of fluid application deviations during curved movement. The control unit modifies the discharge rate on-the-fly to compensate for fluid inertia and viscosity effects that cause deviations from the intended curved application path.
3Ease of operation
If the discharge amount is controlled based on application speed, then the discharge rate can be regulated, but the fluid track deviates when changing from straight to curved paths
Solution Approach 1:
The system uses detection units to monitor the actual fluid application track and provides feedback to the control unit. This feedback loop allows the system to distinguish between intentional curved track changes and unwanted deviations, enabling the control unit to adjust discharge amount dynamically to maintain precision during track transitions.
Solution Approach 2:
The track generation unit calculates the expected fluid application track in advance based on the planned nozzle path and fluid characteristics. This preliminary calculation allows the control system to prepare appropriate discharge rate profiles that account for upcoming curved sections, ensuring smooth transitions and accurate application without sudden changes in discharge amount.

AI summary
A track generation device generates a track of a fluid discharge unit that discharges a fluid for applying the fluid to a surface of an object along a target application track. The track generation device includes a storage unit and a track generation unit. The storage unit stores a time-series model indicating a relationship between the track of the fluid discharge unit and an application track of the fluid in consideration of behavior of the fluid due to a viscosity, and the relationship is learned based on an actual track of the fluid discharge unit and an actual application track of the fluid. The track generation unit is configured to generate the track of the fluid discharge unit corresponding to the target application track using the time-series model upon reception of the target application track.
