Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual picking and placing of polishing heads is used, then operation simplicity is maintained, but labor cost increases and productivity decreases
Solution Approach 1:
The polishing head management system enables self-service operation through automated identification and tracking. When a polishing head is placed in the storage device, the system automatically identifies it via barcode scanning, records its information, and tracks its usage status without requiring manual intervention. This self-service mechanism resolves the contradiction by eliminating manual labor while maintaining operational simplicity.
Solution Approach 2:
The patent replaces manual mechanical operations with an automated electronic system. The barcode scanner, data acquisition device, and computer work together to automatically identify, record, and track polishing heads, substituting the manual mechanical process of picking, placing, and recording information. This substitution improves productivity while the integrated system design keeps the complexity manageable.
2Loss of information
If manual recording of use time with paper is used, then device complexity is minimized, but loss of information occurs and environmental harm increases
Solution Approach 1:
The system creates an electronic copy of the polishing head's identification information through barcode scanning. Instead of manually transcribing data onto paper, the barcode scanner automatically captures and digitizes the information, storing it in the computer's database. This electronic copying eliminates data loss associated with manual recording while the digital storage system manages complexity efficiently.
Solution Approach 2:
The barcode acts as an intermediary that carries identification information between the polishing head and the data management system. By scanning the barcode, the system automatically retrieves and records the polishing head's information without requiring manual data entry. This intermediary mechanism ensures accurate information transfer while the automated process keeps the overall system complexity manageable.
3Productivity
If automated pick-and-place device is implemented, then labor cost decreases and productivity increases, but device complexity increases
Solution Approach 1:
The patent merges multiple functions into an integrated system: the storage device houses both the polishing heads and the barcode scanning capability, while the data acquisition device combines identification, recording, and tracking functions. This merging reduces the number of separate components needed, thereby improving productivity while keeping the overall device complexity manageable through functional integration.
Solution Approach 2:
The data acquisition device serves multiple functions: it identifies polishing heads through barcode scanning, records their information in the database, tracks their usage status, and manages their storage locations. This multi-functionality improves productivity by eliminating the need for separate devices for each task while managing complexity through a single versatile system.
