Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If work management systems associate fastening data with tools and measuring instruments to improve traceability, then manufacturing quality and traceability are improved, but the complexity of the system increases and manual tracking remains time-consuming
Solution Approach 1:
The server system performs multiple functions: storing fastening member information, managing work schedules, tracking tool usage, verifying fastening data, and generating reports. This multi-functional approach consolidates what would otherwise require separate systems, improving traceability while controlling overall system complexity through integration.
Solution Approach 2:
The system automatically verifies fastening data by comparing actual fastening results against predetermined standards and schedules. This feedback mechanism ensures quality control and traceability without requiring manual verification, reducing the time and effort needed for quality assurance while maintaining system reliability.
2Manufacturing precision
If manual tracking and verification of fastening processes are performed to ensure quality, then manufacturing precision is maintained, but man-hours and processing time increase significantly
Solution Approach 1:
The fastening management system automatically performs verification of fastening data by comparing actual results with predetermined standards. The system self- verifies compliance without requiring manual intervention, maintaining manufacturing precision while eliminating the time-consuming aspect of manual tracking and verification.
Solution Approach 2:
The system replaces manual mechanical tracking methods with automated electronic data collection and verification. Fastening data is automatically captured and verified by the server system, substituting manual verification processes with automated computational verification, thereby maintaining precision while reducing man-hours.
3Reliability
If detailed tracking of each fastening process step is implemented to prevent errors, then work reliability is improved, but the ease of operation decreases due to increased documentation requirements
Solution Approach 1:
The system automatically captures and records fastening process data without requiring manual documentation. The automated data collection and verification processes maintain work accuracy while eliminating the burden of manual documentation, thereby preserving ease of operation.
Solution Approach 2:
The system creates automatic digital copies of fastening data and process information. This automated record-keeping replaces manual documentation requirements, ensuring detailed tracking for reliability while maintaining operational simplicity by eliminating the need for manual data entry and documentation.
4Productivity
If automated verification systems are introduced to reduce manual labor, then productivity increases, but the device complexity and initial investment increase
Solution Approach 1:
The server system performs multiple functions including data storage, schedule management, verification, and reporting within a single integrated platform. This multi-functionality increases productivity by automating multiple processes while controlling infrastructure complexity through consolidation rather than requiring multiple separate systems.
Solution Approach 2:
The automated verification system provides real-time feedback on fastening quality and compliance. This automated feedback loop increases processing efficiency by eliminating manual verification steps while the feedback mechanism itself is implemented through software logic rather than complex additional hardware, balancing productivity gains with manageable system complexity.

AI summary
Provided are a work management device and a work management method, whereby progress-as-predicted for prescribed work can be readily confirmed and the number of work hours can be reduced. A work management server 7 obtains tightening information relating to a bolt, etc., (a tightening member having a first IC tag) that is tightened when attaching and removing a component (a component having a second IC tag) by using a tool 5, determines whether or not the combination of information indicated by the first IC tag and information indicated by the second IC tag, as read from this tightening information, is correct, and outputs the determination results.
