Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual methods are used to attach blades to a rotating body, then the process is simple to implement, but work efficiency is low and precision is poor
Solution Approach 1:
The patent replaces manual mechanical attachment operations with an automated system that uses measurement units to detect perimeter and gap dimensions, a selection unit to determine optimal blade arrangements, and an attachment unit to execute precise positioning. This substitution of manual mechanical operations with automated measurement and control systems directly resolves the contradiction by dramatically improving productivity while accepting increased system complexity.
Solution Approach 2:
The attachment device performs self-measurement of the attachment portion's perimeter and automatic determination of blade spacing gaps, eliminating the need for external measurement tools and manual calculations. The system autonomously selects attachment configurations and executes attachment operations, enabling the process to serve itself and thereby improving efficiency without requiring additional manual intervention.
2Manufacturing precision
If automated measurement and selection systems are introduced, then manufacturing precision is improved, but device complexity increases
Solution Approach 1:
The patent replaces manual measurement and positioning operations with automated measurement units that detect perimeter and gap dimensions, and a selection unit that computationally determines optimal blade arrangements. This substitution introduces measurement and control systems that significantly improve manufacturing precision by eliminating human error in measurement and positioning.
Solution Approach 2:
The system incorporates measurement units that continuously detect the attachment portion's perimeter and the gaps between attached blades, feeding this information back to the selection and attachment units. This feedback mechanism enables real-time adjustments to ensure precise blade positioning and spacing, directly improving manufacturing precision through closed-loop control.
3Reliability
If precise measurement of perimeter and gap is performed, then attachment quality is improved, but measurement and detection difficulty increases
Solution Approach 1:
The patent employs specialized measurement units designed to automatically detect the attachment portion's perimeter and the gaps between blades. These measurement units replace difficult manual measurement tasks with automated sensing systems, improving attachment quality by ensuring consistent and accurate measurements while reducing the operational difficulty through automation.
Solution Approach 2:
The measurement units are integrated into the attachment device itself, enabling the system to perform self-measurement of critical dimensions without requiring external measurement tools or manual intervention. This self-service capability improves attachment quality through consistent automated measurement while reducing the difficulty by eliminating the need for separate measurement procedures.

AI summary
An attachment device attaches a plurality of attachment target members to an attachment portion formed in a circumferential direction of a rotating main body portion. A first measurement unit measures a physical amount concerning a perimeter of the attachment portion. An attachment unit attaches, to the attachment portion, the plurality of attachment target members selected based on the physical amount concerning the perimeter measured by the first measurement unit. A second measurement unit measures a physical amount concerning a gap between the adjacent attachment target members to be attached by the attachment unit.
