Solution Overview
Problem
Existing service cart technologies have not effectively implemented semi-automated or fully-automated systems capable of performing multiple tasks, thereby failing to completely remove the human factor from job positions, limiting productivity, profitability, and customer convenience.
Innovation Solution
A service cart device equipped with a main body, storage members, a top member, attachment members, computation interfaces, drive units, and sensors, which includes a buoyant top member, active lock members, and a power unit, allowing for self-propulsion, object detection, and communication with user devices to optimize route planning and delivery of goods.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual service carts are used for transporting goods, then human labor is required for operation, but this increases operational costs and reduces productivity
Solution Approach 1:
The service cart is equipped with autonomous navigation capabilities including sensors, processors, and control systems that enable it to navigate, avoid obstacles, and deliver goods without human intervention. The cart independently performs tasks such as route planning, obstacle detection, and self-positioning, effectively removing the need for manual operation while maintaining efficient goods transportation.
2Productivity
If automated navigation systems are added to service carts, then productivity increases, but device complexity increases
Solution Approach 1:
The service cart integrates multiple functions into a single platform: navigation (GPS, inertial sensors), obstacle detection (ultrasonic, optical sensors), communication (wireless modules), and power management all work together in a unified system. This multi-functional integration achieves high delivery precision while managing system complexity through coordinated operation of various subsystems.
3Reliability
If sensor devices are integrated for obstacle detection, then safety improves, but device complexity increases
Solution Approach 1:
The service cart employs multiple sensor types (ultrasonic sensors, optical sensors, infrared sensors) that continuously scan the environment ahead of the cart to detect obstacles before collision occurs. The system processes sensor data in real-time and initiates avoidance maneuvers in advance, ensuring safe operation while managing sensor complexity through centralized control algorithms.

AI summary
A service cart device to transport goods and services which may include a main body member, storage members, top member, attachment member, and computation interface. The device may also include wheel members, one or more of a drive unit, and sensor devices. The storage members may be carried by the main body member. The top member may be positioned above and carried by the main body member. The attachment member may be attached to an upper portion of the top member. The wheel members may be rotatably attached to a lower surface of the main body member. The drive units may selectively rotatably move at one or more of the wheel members. The sensor devices may be configured to detect adjacent objects and surfaces. The sensor devices may emit a detection signal relating to adjacent to object(s) and surface(s) detected. The top member may comprise a buoyant material.
