Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a treatment device is used to thoroughly treat the photocuring model, then the cleaning effectiveness is improved, but the treatment process becomes less intelligent and more manual
Solution Approach 1:
The patent implements a feedback assembly that includes sensors (such as photoelectric sensors or cameras) to detect the position, orientation, and resin distribution state of the member-to-be-cleaned in real-time. This detection information is fed back to the control system, which automatically adjusts the treatment unit's parameters (such as cleaning agent spray amount, rotation speed, or treatment head position) to optimize the cleaning process. This closed-loop feedback mechanism transforms the manual treatment process into an intelligent automated system that maintains high cleaning effectiveness while reducing human intervention.
2Productivity
If the member-to-be-cleaned is rotated at high speed for centrifugal cleaning, then resin removal efficiency is improved, but the complexity of the driving unit increases
Solution Approach 1:
The patent combines the driving unit for rotation with the treatment unit in an integrated structure. The driving unit (such as a motor or servo mechanism) is directly coupled to the member-to-be-cleaned or to a rotating platform that holds the member, allowing synchronized rotation and treatment operations. This merging eliminates the need for separate, complex positioning and rotation mechanisms, reducing overall device complexity while maintaining high-speed centrifugal cleaning capability for improved resin removal efficiency.
Solution Approach 2:
The patent employs a dynamic driving unit that can automatically adjust rotation speed based on real-time feedback from the feedback assembly. The control system modulates the driving unit's output to optimize rotation speed during different stages of the cleaning process (e.g., higher speed for initial resin removal, lower speed for final cleaning), thereby achieving high productivity without requiring a permanently over-engineered high-speed mechanism throughout the entire process.
3Manufacturing precision
If more cleaning agent is used to ensure thorough resin removal, then cleaning completeness is improved, but agent consumption increases
Solution Approach 1:
The patent employs the treatment unit to deliver cleaning agents locally and precisely to specific areas of the member-to-be-cleaned based on feedback from the feedback assembly. Instead of uniformly applying cleaning agent to the entire surface, the system identifies regions with residual resin and concentrates the cleaning agent application on those specific locations. This localized treatment approach ensures thorough resin removal from critical areas while minimizing unnecessary agent consumption on already clean surfaces.
Solution Approach 2:
The control system dynamically adjusts cleaning agent application parameters (such as spray pressure, flow rate, or dosage) based on real-time feedback about the resin distribution state. When the feedback assembly detects heavy resin accumulation in certain areas, the system increases agent application in those regions; when areas are already clean, the system reduces or stops agent application. This parameter modulation based on actual conditions achieves complete cleaning while optimizing agent consumption.
