Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional treatment devices for workpieces are inefficient in resource utilization and fail to effectively match the treatment process with the geometry of the workpieces, leading to suboptimal treatment outcomes.
Innovation Solution
The treatment device features independently actuated nozzle units, allowing for adjustable angles of incidence of the treatment medium jets, enabling precise alignment with the workpiece geometry through the use of multiple nozzle actuators, which can be pivoted or moved to optimize the treatment process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional treatment devices use fixed or collectively actuated nozzles, then the device structure is simple, but the treatment effectiveness is reduced due to inability to match workpiece geometry
Solution Approach 1:
The nozzle device is divided into multiple independent nozzle units, each with its own actuator. This segmentation allows each nozzle to be independently controlled to match different areas of the workpiece geometry, thereby improving treatment effectiveness while distributing the complexity across modular units.
Solution Approach 2:
The nozzles are made dynamically adjustable through individual actuators that can change the angle of incidence and direction of treatment medium jets in real-time. This dynamic adaptability enables the system to match varying workpiece geometries during the treatment process, resolving the contradiction between treatment precision and system complexity.
2Adaptability or versatility
If individually actuated nozzle units are used to match workpiece geometry, then treatment effectiveness is enhanced, but the number of actuators and system complexity increases
Solution Approach 1:
Each nozzle unit is designed as a universal module that can be independently actuated to treat different areas of various workpiece geometries. The standardized nozzle unit design with integrated actuators allows the same modular component to adapt to multiple workpiece types, reducing overall system complexity while maintaining high versatility.
Solution Approach 2:
The system achieves geometry matching by changing parameters such as the angle of incidence and direction of the treatment medium jets through actuator control. This parameter-based adjustment allows a single nozzle unit design to adapt to different workpiece geometries without requiring physically different nozzle configurations, thereby reducing complexity.
3Productivity
If multiple independently actuated nozzles are used to optimize treatment angles, then resource utilization improves, but the device complexity and control requirements increase
Solution Approach 1:
The control system is designed to autonomously coordinate the multiple actuators and nozzles based on pre-programmed treatment parameters. The system automatically adjusts each nozzle's angle and direction to optimize resource utilization, reducing the need for complex manual control while improving productivity through automated resource management.
Solution Approach 2:
The control system incorporates feedback mechanisms that monitor the treatment process and automatically adjust actuator positions to optimize resource utilization. This feedback-based control allows the system to maintain high productivity by dynamically allocating treatment resources based on real-time conditions, thereby managing complexity through intelligent automation.
