AI Technical Summary
Technical Problem
After being changed to a thinner design, the connection stability between the sofa's base, armrests, and backrest cannot meet the requirements of the screw and bolt fixing method, affecting the overall structural stability.
Method used
Limiting holes are provided on any two of the connected parts of the armrest, backrest, and base. The connecting section of the connector passes through the limiting hole, and the limiting section is located on the side away from the second component, forming a support and limiting fit to ensure the stability of the connection.
Benefits of technology
Even after the sofa components were made thinner, the stability of the connection between the two parts was still guaranteed, thus ensuring the stability of the overall sofa structure.
