Movable Floor Box Loading System for Delivery Vehicles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for unloading boxes from vehicles during home delivery are inefficient, requiring significant physical effort from handlers, leading to prolonged unloading times, potential product breakage, and musculoskeletal disorders, while also disrupting temperature control in refrigerated compartments.
Innovation Solution
A vehicle system featuring wheeled trolleys with running rails and a roof bar to secure boxes, along with anti-roll bars and a sliding shuttle mechanism that reduces manual effort by guiding boxes towards the vehicle opening, ensuring stable transport and quick unloading without handlers entering the vehicle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If packages are stacked deep in the loading volume for efficient space utilization, then cargo capacity is improved, but unloading time and physical effort increase significantly
Solution Approach 1:
The patent applies preliminary action by pre-positioning packages on a movable floor that can be shifted forward. Packages are loaded in reverse order (last-delivery packages first) and the floor is moved forward during unloading to bring packages to the door automatically, eliminating the need for handlers to physically retrieve items from deep within the cargo area.
Solution Approach 2:
The patent implements dynamics through the movable floor mechanism that can shift position within the cargo area. The floor transitions from a static loading surface to a dynamic element that actively moves packages toward the exit, adapting the cargo system's configuration during the unloading process to maintain efficiency.
2Ease of operation
If the exterior door is opened for extended periods to facilitate package delivery, then ease of operation is improved, but temperature control deteriorates
Solution Approach 1:
The movable floor is positioned in advance to bring delivery packages to the door area before the door needs to be opened. This preliminary positioning action allows the door to remain closed longer, maintaining temperature stability while still enabling convenient delivery operations when needed.
Solution Approach 2:
The system performs self-service by automatically moving packages to the delivery position through the movable floor mechanism, reducing the need for manual handling and minimizing the time the door must remain open for delivery operations.
3Ease of operation
If packages are placed close to the cabin for easy access, then ease of operation is improved, but the first packages to be delivered are difficult to reach
Solution Approach 1:
The patent applies inversion by loading packages in reverse chronological order of delivery (last-delivery packages first) and using the movable floor to shift them forward. This inverts the traditional loading approach, allowing the first packages to be delivered to automatically move to the door position while maintaining efficient space utilization deeper in the cargo area.
4Adaptability or versatility
If handlers manually move packages from the back of the vehicle during delivery, then adaptability to home delivery is improved, but physical fatigue and musculoskeletal disorders increase
Solution Approach 1:
The movable floor performs preliminary action by automatically transporting packages from the rear cargo area to the door position before the handler needs to access them. This eliminates the need for handlers to physically move packages through the cargo area, reducing physical fatigue while maintaining home delivery adaptability.
Solution Approach 2:
The movable floor acts as an intermediary mechanism between the cargo storage area and the delivery point. It mediates the transport of packages, taking over the physical work of moving items from the back to the front, thereby protecting handlers from physical strain while enabling flexible delivery operations.

AI summary
The invention relates to a vehicle for transporting boxes in a storage space, said boxes being stacked on at least one trolley with castors engaging with at least one guide rail attached to the floor such as to guide the movement of said trolley, the vehicle comprising at least one device exerting a horizontal force on a row of boxes placed on at least one trolley in order to move same towards an opening of the vehicle. The vehicle also comprises at least one roof bar (8) holding, at the upper portion, at least one stack of boxes placed on a trolley. The presence of a roof bar ensures that the boxes are adequately held in the loading space, thus preventing breakage during transport.
