Delivery Vehicle Cab-Cargo Layout With Same-Side Sliding Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Delivery vehicles face challenges in efficiently accessing and organizing cargo while minimizing the overall footprint and ensuring occupant safety during delivery operations.
Innovation Solution
A vehicle design with a cab and cargo body configuration featuring sliding doors on the same side, a roof cap assembly, and multiple access points, including a sliding access door in the partition, side access door, and a retractable rear access door, along with adjustable shelves to optimize storage and accessibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If multiple access points are provided for cargo accessibility, then cargo accessibility is improved, but device complexity increases
Solution Approach 1:
The cargo body is divided into multiple sections with different access points: a first access point in the cab for small items, a second access point on the side for medium packages, and a third access point at the rear for large items. This segmentation allows different types of cargo to be accessed through different doors, improving operational efficiency without requiring a complete redesign of the vehicle structure.
Solution Approach 2:
Access points are distributed across multiple dimensions of the vehicle - front (cab), side, and rear - rather than concentrating all access through a single location. This spatial distribution allows the delivery operator to access cargo from various directions simultaneously, reducing the need to maneuver around the vehicle and improving delivery speed.
2Ease of operation
If sliding doors are used on the same side, then ease of operation is improved, but manufacturing complexity increases
Solution Approach 1:
Both the front door and side door utilize sliding door mechanisms rather than traditional hinged doors. This universal application of the sliding door design allows for consistent manufacturing processes and assembly techniques across different door locations, actually reducing overall manufacturing complexity despite the increased operational versatility.
3Object-affected harmful factors
If cab height is reduced for safety, then occupant safety is improved, but cargo storage volume decreases
Solution Approach 1:
The cargo body is designed to extend vertically above the cab roof, utilizing the vertical dimension rather than increasing cab height. This allows the cargo storage volume to be increased without compromising occupant safety, as the additional cargo space is positioned above and separate from the occupant compartment.
Solution Approach 2:
The vehicle is segmented into two distinct vertical zones: the cab at a safe, lower height for occupant protection, and the cargo body extending upward for maximum storage capacity. This segmentation allows each zone to be optimized independently - the cab for safety and the cargo body for volume.
4Ease of operation
If multiple sliding doors are provided, then cargo organization is improved, but device complexity increases
Solution Approach 1:
The cargo body is segmented into different access zones with dedicated sliding doors: front access for frequently accessed items, side access for bulk cargo, and rear access for large packages. Each door serves a specific organizational function, allowing cargo to be sorted and accessed by type and frequency without requiring complex internal cargo management systems.

AI summary
A vehicle includes a chassis and a vehicle body coupled to the chassis. The vehicle body includes a cab disposed on a forward end of the chassis and a cargo body disposed on a rear end of the chassis. The cab includes a front door that is slidably engaged to the cab. The cargo body includes a side door that is slidably engaged to the cargo body. The front door and the side door are disposed on the same side of the vehicle.
