Pusher Assembly Storage Frame for Easier Product Retrieval

The patent applies the dynamics principle by introducing a movable shelf system where shelves can be automatically repositioned along vertical rails. This allows the storage structure to dynamically adapt to retrieval needs, automatically bringing products from higher shelves down to accessible positions, thereby maintaining high storage capacity while eliminating the labor-intensive nature of manual retrieval.

The patent implements the self-service principle through an automated retrieval mechanism where the system itself performs the work of bringing products to users. The movable shelves automatically descend or reposition containers to an accessible position without requiring users to physically reach, climb, or manually handle heavy items, thereby eliminating repetitive strain and injury risks while maintaining ease of operation.

The patent applies segmentation by dividing the large storage center into multiple modular rack units, each equipped with independent movable shelf mechanisms. This segmentation allows parallel operation of multiple retrieval points simultaneously, enabling high-volume storage while maintaining high retrieval efficiency through distributed, concurrent access across multiple modular sections.
