Drawer Lateral Wall Laser Deformation for Retaining Device Stability

The patent applies preliminary action by performing laser deformation treatment on the support profile before the laser welding process. This pre-treatment creates controlled stress concentrations and material modifications in advance, which prevent detachment during subsequent loading. The deformation is applied at specific locations on the support profile to create preferential deformation zones that enhance connection reliability under load.

The patent utilizes parameter changes by modifying the physical state of the support profile through laser-induced thermal deformation. The laser treatment changes local material parameters such as hardness, stress distribution, and structural density in the deformation zones. These parameter changes create a more reliable connection that can withstand operational loads without detaching, while maintaining the precision benefits of laser welding.

The patent merges two laser-based processes (deformation treatment and welding) into a single integrated manufacturing system. Both processes use the same laser technology platform, allowing them to be performed sequentially in one setup without requiring additional equipment or complex process integration. This merging approach increases strength through combined thermal effects while minimizing the increase in device complexity.

The patent replaces traditional mechanical strengthening methods (such as mechanical fastening, riveting, or cold-forming) with laser-based thermal deformation and welding. This substitution eliminates the need for additional mechanical components and complex assembly operations, achieving enhanced load-bearing capacity through controlled thermal processes instead of mechanical means.
