Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the electrode plate is not properly supported during laser cutting, then the cutting process is simpler, but the electrode plate shakes and cutting quality deteriorates
Solution Approach 1:
A supporting device is introduced as an intermediary between the laser cutting system and the electrode plate. This supporting device includes a supporting component with an abutting surface that contacts the electrode plate, providing stable support during cutting. The supporting component acts as a mediator to eliminate plate shaking without complicating the overall cutting system architecture.
2Productivity
If the laser power is increased to improve cutting speed, then productivity increases, but the risk of damaging components through excessive laser energy increases
Solution Approach 1:
The light absorbing component converts the harmful excessive laser energy that would otherwise damage components into useful heat energy. By positioning this component to intercept residual laser beams, the system transforms potential harm into a beneficial function, allowing higher laser powers to be used safely for improved cutting speed while protecting surrounding components from damage.
3Reliability
If a light absorbing component is added to manage residual laser energy, then component safety improves, but device complexity increases
Solution Approach 1:
The light absorbing component is merged with the existing supporting device structure. The supporting component serves dual functions: providing mechanical support for the electrode plate and housing the light absorbing component for managing residual laser energy. This integration reduces overall device complexity while maintaining both support and laser safety functions.

Implementation Method 1
the body includes a light absorbing component capable of absorbing the laser passing through the electrode plate
Implementation Method 2
the laser passing through the electrode plate will be dispersed in the light transmitting component after passing through the focal point, and the power density of the laser can be reduced

AI summary
An electrode plate supporting device may be used in coordination with the laser assembly and may include a body constructed with an abutting surface for abutting against an electrode plate to tension the electrode plate. The laser assembly may be configured to emit laser to the abutting surface. During laser cutting, the electrode plate may abut against the abutting surface and closely fits the abutting surface to extend fully and thus may be in a flattened state, and therefore, the problem of defocusing caused by a wavy edge may be solved. Moreover, supported by the abutting surface, the electrode plate may be tensioned and not prone to shaking, and therefore, problems such as failing to cut off the incoming material due to easy shaking of the electrode plate may be effectively solved.
