Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If double-point incremental forming is used to achieve local incremental deformations, then flexibility and moldless manufacturing are improved, but geometric accuracy and forming range deteriorate
Solution Approach 1:
The patent divides the forming process into multiple discrete steps by slicing the 3D model into layered 2D curves. Each layer represents a discrete forming stage with specific tool paths, allowing incremental deformation to be controlled in segmented steps rather than continuous motion, thereby improving geometric accuracy while maintaining flexibility
Solution Approach 2:
The patent performs preliminary actions by pre-calculating and planning the complete tool paths for both forming and support tools before actual manufacturing. The 3D model is sliced and processed to generate all necessary 2D curves and tool paths in advance, allowing optimization of the entire forming sequence beforehand to ensure high geometric accuracy
2Ease of operation
If traditional incremental forming control methods are used, then process simplicity is maintained, but forming accuracy and control optimization deteriorate
Solution Approach 1:
The patent implements feedback mechanisms by using the sliced 3D model to continuously guide and adjust tool paths during forming. The pre-calculated 2D curves serve as reference feedback for controlling tool positions and motions, ensuring that each incremental step follows the intended geometry accurately while maintaining systematic control
Solution Approach 2:
The patent performs preliminary path planning and optimization before manufacturing by slicing the model and generating all tool paths in advance. This preliminary action allows comprehensive optimization of forming sequences, support strategies, and tool trajectories to maximize forming accuracy while keeping the actual manufacturing process straightforward
3Device complexity
If single-point incremental forming is used, then device complexity is reduced, but forming capability and accuracy deteriorate
Solution Approach 1:
The patent merges the functions of forming and support operations into a coordinated dual-tool system. Both the forming tool and support tool operate simultaneously with synchronized tool paths derived from the same sliced 3D model, combining their capabilities to achieve high forming accuracy and capability while maintaining systematic control
