Solution Overview
Problem
Conventional teaching operations for applying a coating agent, such as a sealing agent, require significant effort and time due to the need for extensive measurement of an object's shape at multiple points, leading to decreased production efficiency.
Innovation Solution
A coating method and device that utilize a nozzle for applying the coating agent, with first and second sensors to detect the object's surfaces, generating detection data before and after application, and comparing extraction data to assess the coating state, allowing for reduced effort and time in teaching operations by intermittently inspecting detection positions within the coating zone.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If teaching operations perform extensive measurement at many measurement points to ensure accurate coating application, then coating precision is improved, but the time and effort required for teaching operations increases significantly
Solution Approach 1:
The patent applies partial measurement by selecting only critical measurement points rather than measuring the entire object surface. The teaching operation focuses on measuring specific regions where coating accuracy is most important, such as corners, edges, or areas with complex geometry, while skipping less critical areas. This reduces the number of measurement points from potentially thousands to a manageable subset that still ensures adequate coating precision.
Solution Approach 2:
The patent divides the object surface into multiple regions and selectively measures only certain regions based on their importance for coating quality. By segmenting the measurement task into critical and non-critical areas, the system can focus computational and measurement resources on the most important zones, thereby reducing overall measurement time while maintaining coating accuracy in key areas.
2Adaptability or versatility
If teaching operations measure shape at numerous measurement points to accommodate object shape variations, then adaptability to shape variations is improved, but the complexity of teaching operations increases
Solution Approach 1:
Instead of measuring the entire object surface to capture all shape variations, the patent measures only critical regions where shape variations most significantly impact coating quality. This partial measurement approach maintains adaptability to shape variations in important areas while avoiding the complexity of processing data from numerous measurement points across the entire surface.
Solution Approach 2:
The patent applies different measurement strategies to different regions of the object based on local requirements. Critical regions with complex geometry or high coating requirements receive detailed measurement, while simpler regions receive minimal or no measurement. This local differentiation reduces overall teaching operation complexity while maintaining adaptability where it matters most.
