Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional visual inspection methods are used to assess positioning accuracy, then the production process remains simple, but the measurement precision and manufacturing precision are insufficient leading to increased rejects
Solution Approach 1:
The patent replaces traditional mechanical visual inspection methods with fluoroscopy imaging technology. The fluoroscopy device captures images of the electronic component and antenna structure, allowing precise measurement of positioning accuracy without direct mechanical contact or complex manual inspection systems.
Solution Approach 2:
The patent introduces fluoroscopy images as an intermediary medium between the positioning process and quality assessment. The images serve as a bridge that translates physical positioning into measurable visual data, enabling accurate measurement without requiring complex direct measurement equipment.
2Manufacturing precision
If fluoroscopy imaging is implemented for real-time positioning verification, then manufacturing precision improves, but device complexity and production time increase
Solution Approach 1:
The fluoroscopy imaging is performed at an early stage in the production process, immediately after the electronic component is placed on the carrier body. This preliminary verification allows for real-time detection and correction of positioning errors before subsequent production steps, preventing waste of time and materials.
Solution Approach 2:
The patent implements a feedback mechanism where fluoroscopy images are analyzed to determine positioning accuracy, and this information is used to adjust the positioning process. The evaluation device provides feedback on whether positioning criteria are met, enabling continuous improvement and correction during production.
3Manufacturing precision
If fluoroscopy imaging and image-based determination are used, then positioning quality is improved, but the difficulty of detecting and measuring increases
Solution Approach 1:
The patent extracts the critical positioning information from the fluoroscopy images by focusing analysis on specific features - the electronic component and antenna structure. By isolating and analyzing only the relevant elements in the images, the measurement process becomes more manageable despite the complexity of the imaging technology.
