Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If multiple shaping members are used to achieve precise edge shaping, then manufacturing precision improves, but device complexity increases
Solution Approach 1:
The device divides the shaping function into multiple independent shaping members (first shaping member, second shaping member, third shaping member) that can be individually controlled and positioned. Each shaping member has its own actuator, allowing precise control of the edge shaping process while maintaining modular device architecture that manages complexity.
Solution Approach 2:
The shaping members are designed to be movable relative to each other through independent actuators, enabling dynamic adjustment of their positions and orientations during the shaping process. This dynamic capability allows the device to achieve complex edge geometries by coordinating the movement of multiple shaping members, resolving the contradiction between precision and complexity.
2Manufacturing precision
If movable shaping members with coordinated movement are implemented, then shaping quality improves, but ease of manufacture deteriorates
Solution Approach 1:
The device is segmented into independent functional modules (shaping members with their respective actuators and positioning mechanisms) that can be manufactured separately and then assembled. This modular approach maintains shaping quality through precise individual component design while simplifying the overall manufacturing process by allowing parallel production of components.
Solution Approach 2:
The shaping members are designed with universal characteristics, where each member can perform multiple functions (shaping, positioning, and coordination with other members). This multi-functionality reduces the total number of specialized components needed, thereby improving ease of manufacture while maintaining high shaping quality through versatile component design.
3Manufacturing precision
If relative axial and radial movements of shaping members are added, then shaping precision improves, but device complexity increases
Solution Approach 1:
Each shaping member is equipped with independent actuators that enable dynamic control of both axial and radial movements. This dynamic positioning capability allows precise control of the shaping process by adjusting the position of each member in multiple degrees of freedom, achieving high shaping precision while managing complexity through coordinated control of individual movable components.
Solution Approach 2:
The device incorporates control mechanisms that monitor the positions and movements of the shaping members and adjust them in real-time to achieve the desired edge geometry. This feedback control enables precise coordination of axial and radial movements, maintaining shaping precision while managing the complexity of the movement mechanisms through automated position control.

AI summary
The device (1) has an outer maintaining body (7) including detachment (22) forming a cavity (13) with an outer side face (14) of an inner maintaining body (6) for receiving an edge (B) of an opening (O) of a metal container (C). A maneuver and control unit controls coordinated displacement of a forming body (11) and the inner and outer maintaining bodies. The control unit ensures an axial relative movement of the forming body with respect to an assembly comprising the maintaining bodies and a radial relative movement of the inner maintaining body with respect to the outer maintaining body.
