Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Metal components with predetermined shapes, such as rocket nozzles or turbine blades, are difficult to support during reprocessing using conventional machine tool support units, leading to instability and reduced reprocessing accuracy.
Innovation Solution
A method involving welding a dummy member to the metal product, allowing it to be securely supported by a first support unit while the dummy member is supported by a second unit, enabling stable reprocessing without shape restrictions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a metal component with a predetermined functional shape is reprocessed using a conventional machine tool support unit, then the reprocessing can be performed, but the metal component cannot be stably supported leading to fixation instability
Solution Approach 1:
A dummy member is introduced as an intermediary component to bridge the metal product and the support unit. The dummy member has a shape specifically designed to be compatible with the support unit's chuck mechanism, while being attachable to the metal product. This intermediary enables stable support and fixation of the metal product during reprocessing without requiring the metal product itself to have a support-compatible shape.
Solution Approach 2:
The system is divided into three separate components: the metal product (with functional shape), the dummy member (with support-compatible shape), and the support unit. This segmentation allows each component to fulfill its specific function independently - the metal product maintains its functional integrity, the dummy member provides support compatibility, and the support unit ensures stable fixation.
2Stability of the object's composition
If a dummy member is welded to the metal product to enable support, then stable fixation is achieved, but the device complexity increases
Solution Approach 1:
The dummy member is designed as a temporary component that is attached to the metal product only during the reprocessing operation. After the reprocessing is completed, the dummy member is removed from the metal product. This approach adds complexity only when necessary (during reprocessing) and restores simplicity afterward, as the dummy member is discarded after serving its purpose.
3Stability of the object's composition
If the metal product shape is restricted to be supportable by the chuck mechanism, then stable support is possible, but the adaptability to different metal product shapes is reduced
Solution Approach 1:
The dummy member serves as a universal intermediary that adapts any metal product shape to the support unit. Instead of requiring the metal product to conform to the support unit's requirements, the dummy member conforms to both the metal product (through welding or attachment) and the support unit (through its chuck-compatible shape), thereby enabling support stability across diverse metal product geometries.
Solution Approach 2:
The dummy member is designed with universal functionality to work with various metal product shapes while maintaining compatibility with the support unit's chuck mechanism. This single dummy member design can accommodate different metal product geometries, making the reprocessing system versatile and adaptable without requiring multiple specialized support solutions.

Function Achieved in This Case
This approach allows for accurate reprocessing of metal products by preventing vibration and ensuring secure fixation, even for complex shapes, with the dummy member being removable post-reprocessing.

AI summary
A method of reprocessing a metal product includes a welding step for welding a dummy member to the metal product, a reprocessing step for reprocessing the metal product in a state where the metal product is supported by a first support unit and the dummy member is supported by a second support unit, and a removal step for removing the dummy member from the metal product after the reprocessing step. The reprocessing of the metal product while the metal product is fixed is thus enabled without restriction from the shape of the metal product.
