Backpack Working Machine Shoulder Pad Attachment

The patent introduces a pad member as an intermediary component between the hard attachment area and the worker's shoulder. This pad member includes a cushioning layer that mediates the contact, allowing the hard structural parts to maintain their strength while the soft cushioning layer prevents shoulder discomfort. The pad member is integrated into the backpack band structure, enabling it to perform both protective and comfort functions simultaneously.

The patent applies local quality by providing cushioning only at the specific attachment area where the hard parts contact the shoulder, rather than making the entire backpack band soft. The pad member with its cushioning layer is localized at the critical contact zone, maintaining structural strength where needed while providing comfort at the contact point with the worker's shoulder.

The patent merges the pad member with the backpack band structure, integrating the cushioning component into the existing band rather than adding it as a separate, independent element. The pad member is combined with the band body and attachment mechanisms, allowing multiple functions (support, cushioning, attachment) to be achieved through a unified structure, thereby reducing overall device complexity.

The pad member is designed to serve multiple functions: it provides cushioning for comfort, acts as a structural support element, and integrates with the attachment mechanisms. By making the pad member multi-functional, the patent avoids adding separate components for each function, thereby reducing device complexity while achieving shoulder discomfort relief.

The pad member is pre-configured with its cushioning layer and attachment structure in a ready state before use. The upper end part is designed to automatically position itself and hold downward when attached, eliminating the need for manual adjustment during operation. This preliminary configuration ensures that when the backpack band is attached, the cushioning effect is immediately active without requiring additional operational steps.

The attachment mechanism is designed to be self-adjusting, where the upper end part of the pad member automatically positions itself to intervene between the attachment and the shoulder. The structure self-regulates to ensure proper cushioning without requiring manual intervention or complex adjustment procedures, thereby maintaining ease of operation while achieving effective cushioning.
