Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional color change valve design is used, then structure is simple, but color change time is long and cleaning efficiency is low
Solution Approach 1:
The patent combines the cleaning agent valve module and color change micro valve module into a single integrated color change valve bank, with both valves sharing a common channel. This merging reduces the number of separate components and connection points, thereby shortening color change time while maintaining structural simplicity.
Solution Approach 2:
The valve bank is segmented into distinct functional modules (cleaning agent valve module and color change micro valve module) that can be independently controlled. This segmentation allows for optimized cleaning pathways and faster color changes without significantly increasing overall device complexity.
2Measurement precision
If traditional paint channel design is used, then manufacturing is simple, but residual paint detection is impossible
Solution Approach 1:
The patent incorporates a turbidity detection module that provides real-time feedback on paint residue in the common channel. The detection results are fed back to the control system, enabling automated determination of whether cleaning is complete and triggering additional cleaning cycles if necessary, achieving precise residual paint detection.
Solution Approach 2:
The common channel serves multiple functions: it transports paint during spraying, transports cleaning agents during color changes, and enables turbidity detection for residual paint monitoring. This multi-functionality reduces the need for separate detection channels while achieving precise measurement capability.
3Productivity
If color change and cleaning are performed separately, then control is simple, but color change efficiency is low
Solution Approach 1:
The control system uses real-time turbidity detection feedback to automatically determine when cleaning is complete and when color change can proceed. This feedback-based control integrates cleaning and color change operations, significantly improving color change efficiency by eliminating manual inspection and decision-making steps.
Solution Approach 2:
The system performs self-monitoring and self-control of the color change process through the turbidity detection module and integrated control system. The system automatically adjusts cleaning duration and triggers color change operations based on real-time channel conditions, achieving high efficiency through automated self-service control.

AI summary
The present disclosure belongs to the technical field of mechanical spraying, and a color change block with detection feedback as well as spraying equipment are provided. The color change block with detection feedback comprises a cleaning agent valve module, a color change micro valve module, a mixing pipe module and a turbidity detection module which are connected in sequence. A complete collinear common channel is formed among these modules, and the wall surface of the common channel is a complete plane. The turbidity detection module is further connected to the control module and used for monitoring the turbidity of a medium flowing through the common channel in real time so as to determine whether the medium in the common channel meets a cleaning requirement or not and feed a determination result back to the control module, and then the control module switches other media to form a closed-loop control.
