Solution Overview
Problem
Existing machining devices for metal containers, such as aerosol and beverage containers, are limited by performance due to the need to absorb kinetic energy during rotating processes, leading to reduced production speed and increased loads on containers and machinery, with known solutions either requiring external energy or being complex and costly to retrofit.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the machine speed is increased to improve productivity, then production speed increases, but the impact forces and stresses on the container increase
Solution Approach 1:
The patent applies preliminary action by pre-accelerating the processing unit in the transverse direction before the main impact. This preparatory movement allows the processing unit to be positioned optimally relative to the container, enabling the main impact to occur at reduced relative speed while maintaining effective machining. The acceleration unit activates the processing unit beforehand, so that when the motion unit impacts the container, the relative velocity is minimized, reducing harmful impact forces.
Solution Approach 2:
The patent implements dynamics by making the processing unit independently movable relative to the motion unit through an acceleration unit. Instead of a fixed rigid connection, the processing unit can dynamically adjust its position and velocity independently. This dynamic capability allows the system to optimize the relative speed between the processing unit and container at the moment of impact, enabling high machine speeds while controlling impact forces through active velocity management.
2Productivity
If the machine speed is increased to improve productivity, then production speed increases, but the time available for rotating processes decreases
Solution Approach 1:
The patent applies dynamics by decoupling the rotating process timing from the main machine cycle through independent activation. The acceleration unit can independently control when the processing unit engages with the container, allowing the rotating process to occur during a controlled, extended period rather than being constrained by the overall machine cycle time. This dynamic timing control enables sufficient process duration even at high production speeds.
Solution Approach 2:
The patent uses preliminary action by activating the processing unit in the transverse direction before the main impact occurs. This pre-positioning allows the rotating process to be initiated and sustained for the necessary duration before the actual machining impact, ensuring that the process has adequate time to complete even when the overall machine cycle is shortened for high productivity.
3Productivity
If an external stop is used to activate the device, then higher cycle rates are enabled, but high stresses are generated in the stop and machine
Solution Approach 1:
The patent applies segmentation by dividing the activation function into two independent parts: the motion unit that provides the main linear movement, and the acceleration unit that provides independent transverse acceleration of the processing unit. This segmentation eliminates the need for a separate external stop, as the processing unit is activated by the acceleration unit itself. The impact forces are thus distributed and controlled within the system rather than concentrated on an external stop, reducing stresses while maintaining high cycle rates.
Solution Approach 2:
The patent implements dynamics by replacing the static external stop with an active acceleration unit that dynamically controls the processing unit's movement. Instead of relying on a fixed stop that absorbs all impact forces, the acceleration unit actively manages the velocity and position of the processing unit, enabling controlled engagement with the container. This dynamic approach reduces peak impact stresses while maintaining high cycle rates through optimized timing and velocity control.
4Object-affected harmful factors
If an air damper is used to reduce impact, then damping effect increases with speed, but the activation point becomes unstable
Solution Approach 1:
The patent applies feedback by using sensors to detect the actual position and velocity of the processing unit, and using this information to adjust the acceleration unit's operation in real-time. This closed-loop control ensures that the processing unit reaches the correct activation point with precise velocity, regardless of variations in machine speed or environmental conditions. The feedback mechanism compensates for any deviations, maintaining manufacturing precision while still achieving impact force reduction through controlled velocity management.
Solution Approach 2:
The patent implements dynamics by replacing the passive air damper with an active acceleration unit that dynamically adjusts its operation based on real-time conditions. Instead of relying on fixed damping characteristics that become unstable at varying speeds, the acceleration unit actively controls the processing unit's velocity and position, maintaining precise activation point positioning across the full range of operating speeds. This dynamic control ensures both impact reduction and positioning accuracy.
