Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If fastening apparatus is designed with fixed fastening device positions, then structural simplicity is maintained, but adaptability to different workpiece models and components deteriorates
Solution Approach 1:
The fastening devices are mounted on movable platforms that can dynamically adjust their positions along the workpiece. The platforms are equipped with drive mechanisms allowing them to move to different locations, transforming the fixed-position system into a dynamic, adaptable system that can accommodate various workpiece models and component configurations.
Solution Approach 2:
The system introduces positional variability along the longitudinal axis of the workpiece by allowing platforms to move to different locations. This adds a dimensional aspect to the fastening apparatus, enabling it to adapt to different workpiece models without requiring complete redesign of the entire system.
2Adaptability or versatility
If fastening apparatus is designed with movable fastening devices, then adaptability to different workpiece models improves, but device complexity increases
Solution Approach 1:
The fastening apparatus is divided into multiple independent platforms, each capable of moving along the workpiece. This segmentation allows each platform to be controlled independently, providing flexibility in positioning fastening devices according to specific component requirements while keeping the control system modular and manageable.
Solution Approach 2:
The movable platforms serve multiple functions: they can position fastening devices at different locations, accommodate various workpiece models, and adapt to different component configurations. This multi-functionality reduces the need for multiple specialized apparatuses, thereby managing complexity through versatile design.
3Productivity
If fastening devices are fixed in position, then ease of operation is maintained, but productivity for complex fastening tasks deteriorates
Solution Approach 1:
The system incorporates automated control mechanisms that enable the platforms to move to predetermined positions and perform fastening operations autonomously. This self-service capability reduces manual intervention, maintains ease of operation through centralized control, while significantly improving productivity for complex fastening tasks involving multiple components and models.

AI summary
A fastening apparatus includes: a main structure, a movable structure mounted to be vertically movable with respect to the main structure, a support connected to the movable structure, a plurality of fastening devices mounted on the support, and a variation mechanism to vary fastening positions of the fastening devices. In particular, the variation mechanism changes the fastening positions on a 2-dimensional coordinate, and also individually moves the plurality of fastening devices along a radial coordinate and an angular coordinate of a polar coordinate system.
