The design includes a frame structure with an operator cage, wheels, and a body featuring a movable rack system, integrated electric motors, a camera system, impact management system, and fingerprint identification for secure access, along with a cap roof and canopy for enhanced functionality and safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional components and systems are used in electric delivery vehicles, then the vehicle structure is simpler and easier to manufacture, but the access, visibility, and safety features are insufficient
Solution Approach 1:
The vehicle body is divided into modular components including a cab section, cargo box, and interchangeable panels. The cab includes segmented access doors (front door, rear door, side door) that can be independently opened or combined, allowing flexible access configurations for different delivery scenarios while maintaining structural integrity
Solution Approach 2:
The vehicle incorporates dynamic access systems including electronically controlled doors that can be opened from either interior or exterior, a movable rack system that transitions between stowed and delivery positions, and interchangeable panels that can be swapped based on delivery requirements, enabling the vehicle to adapt to varying operational needs
2Ease of operation
If the operator cabin is positioned on one side of the vehicle, then the vehicle structure is simplified, but the access and visibility from both sides are limited
Solution Approach 1:
The access door system is designed with multi-functionality where the front door, rear door, and side door can each serve multiple purposes: providing operator access, serving as cargo access points, and combining with other doors to create larger opening configurations. This universal design allows a single door system to fulfill multiple operational requirements
Solution Approach 2:
The doors incorporate electronic control systems that allow flexible operation modes - individual doors can be opened independently or multiple doors can be opened together to create larger access openings. The system dynamically adapts to different access needs based on delivery requirements, improving ease of operation without requiring separate fixed access points
3Illumination intensity
If traditional mirror systems are used, then the vehicle structure is simpler, but the visibility and safety monitoring capabilities are insufficient
Solution Approach 1:
Traditional mechanical mirrors are replaced with electronic camera systems that capture and transmit visual information to the operator. The camera system includes multiple sensors positioned at strategic locations (front, rear, sides) that provide comprehensive vehicle surroundings monitoring, replacing the limited field of view of physical mirrors with electronic imaging capabilities
Solution Approach 2:
Camera systems and sensors are positioned as intermediary elements between the operator and the vehicle surroundings. These intermediaries capture visual data from areas not directly visible to the operator and transmit this information to the operator's display, enabling indirect observation of blind spots and rear areas without requiring the operator to physically turn or extend their view
4Adaptability or versatility
If fixed cargo storage is used, then the vehicle structure is simpler, but the adaptability for different delivery configurations is reduced
Solution Approach 1:
The cargo storage system replaces fixed shelving with a movable rack mechanism that can be positioned along tracks at different locations within the cargo box. The rack can be easily moved between stowed position (distant from operator seat) and delivery position (close to operator seat), allowing flexible cargo access and delivery configurations without requiring complex mechanical structures
Solution Approach 2:
The cargo box is designed with modular components including the movable rack, interchangeable panels, and segmented storage areas. This segmentation allows different portions of the cargo box to be configured independently, enabling adaptation to various delivery scenarios such as parcel delivery, food delivery, or larger item transport by reconfiguring the internal layout

AI summary
A land vehicle includes a frame structure, a plurality of wheels supported by the frame structure, and a body supported by the frame structure. The frame structure includes an operator cage that at least partially defines an operator cabin and a rear compartment positioned rearward of the operator cage in a longitudinal direction. The body includes a first sidewall arranged on one side of the vehicle and a second sidewall arranged on another side of the vehicle opposite the first sidewall.
