Solution Overview
Problem
Autonomous vehicles lack infrastructure for detecting and managing objects within the vehicle, such as luggage, leading to challenges in communication and storage management.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If autonomous vehicles use basic transportation functionality without object detection infrastructure, then vehicle simplicity is maintained, but object management capability is insufficient
Solution Approach 1:
The system divides the vehicle into multiple storage bins with individual transceivers, allowing independent detection and management of objects in each bin. This segmentation enables granular object tracking without requiring a completely complex centralized detection system throughout the entire vehicle.
Solution Approach 2:
The transceivers in storage bins serve multiple functions: detecting object presence, communicating with the computer system, and enabling user notifications. This multi-functionality reduces the need for separate dedicated components for each detection and communication task, thereby managing system complexity.
2Productivity
If the vehicle implements comprehensive object detection and storage management systems, then object management efficiency is improved, but device complexity increases
Solution Approach 1:
Objects with embedded transmitters automatically announce their presence and location to the vehicle's computer system. The system self-updates on object locations without requiring manual input or complex active scanning mechanisms, thereby improving management efficiency while keeping detection system complexity relatively low.
Solution Approach 2:
The transceivers in storage bins provide continuous feedback to the computer about object presence and location. This feedback mechanism enables real-time object management and user notifications without requiring complex periodic scanning or manual checking systems.
3Measurement precision
If the vehicle uses simple storage bins without transceivers, then manufacturing cost is reduced, but object detection capability is insufficient
Solution Approach 1:
Transceivers are placed locally in specific storage bins that require object detection capability, rather than equipping all storage spaces uniformly. This allows high detection precision where needed while maintaining simpler, more cost-effective manufacturing for bins where basic storage suffices.
4Measurement precision
If the system continuously monitors all storage bins for object presence, then object tracking accuracy is improved, but energy consumption increases
Solution Approach 1:
The system uses periodic communication between transmitters and transceivers rather than continuous monitoring. Objects periodically transmit their presence information, and transceivers periodically check for objects, achieving accurate tracking while consuming less energy compared to continuous active scanning or monitoring.

AI summary
An object is identified within a specified distance from a vehicle. The object is assigned a position in the vehicle and the object is detected in the position. Upon detecting the object in the position, a vehicle component is actuated.
