✅ ‌Translation (Strictly Accurate, Maintaining Original Meaning):‌

When horizontal and vertical frames are joined, no soft double-sided adhesive tape is applied on the mating surface, resulting in gaps at the joint and causing water leakage.

Solution:‌ Apply double-sided adhesive tape on the cross-section of the joint, or design a connective component with a glue injection channel; after assembly, inject sealant to achieve sealing at the connection.

The cross-sectional structure is unreasonably designed, and the uneven distribution of screw fastening points causes uneven stress during tightening, leading to gaps.

Solution:‌ Modify the cross-sectional design to ensure uniform stress distribution when screws are tightened.

The fastening screws are too short, resulting in insufficient clamping force, making the frame prone to deformation and gaps.

Solution:‌ Replace the screws with appropriate specifications, and pay attention to the dimensional tolerance fit between the screw diameter and the screw fastening holes in the profile.
