Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current Automated Valet Parking (AVP) systems rely on central servers for infrastructure assistance data processing, leading to increased data transfer distances, hardware requirements, and bandwidth needs, which can be inefficient and costly.
Innovation Solution
Implementing an edge computing architecture within the parking facility, where base units process infrastructure assistance data from a limited number of surroundings sensors, reducing data transfer distances and hardware needs, and using a daisy chain topology for efficient expansion and communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a central server is used for processing infrastructure assistance data in AVP systems, then centralized control and data management are achieved, but data transfer distances increase, bandwidth requirements increase, and hardware costs increase
Solution Approach 1:
The patent segments the centralized server into multiple distributed base units, each responsible for processing sensor data and providing infrastructure assistance data for its local area. This segmentation reduces data transfer distances and bandwidth requirements while maintaining reliable control through the distributed network of base units.
Solution Approach 2:
The patent transitions from a single-point centralized architecture to a multi-point distributed architecture, adding spatial distribution as a new dimension. Base units are positioned at different locations within the parking facility, creating a distributed network that reduces data transfer distances while maintaining centralized coordination through the parking facility management system.
2Loss of information
If a central server processes all surroundings sensor data, then comprehensive data availability is achieved, but bandwidth requirements and hardware needs increase
Solution Approach 1:
The patent applies local quality by having each base unit process only the sensor data from its immediate surroundings rather than all sensor data from the entire parking facility. This localized processing reduces the data volume each base unit must handle while ensuring comprehensive coverage through the collective action of multiple base units.
Solution Approach 2:
The patent implements partial action by having each base unit process only a subset of the total sensor data - specifically, data from sensors in its local area. This partial processing approach reduces overall system hardware requirements while maintaining complete data availability through the distributed network of base units.
3Area of stationary object
If base units are connected to multiple surroundings sensors across the entire parking facility, then complete area coverage is achieved, but data transfer complexity and bandwidth needs increase
Solution Approach 1:
The patent segments the parking facility into multiple local areas, each monitored by a base unit. Each base unit is connected only to sensors in its local area, creating manageable segments that reduce data transfer complexity. The collective segments cover the entire parking facility area.
Solution Approach 2:
The patent implements local quality by having each base unit handle only the sensors and data in its immediate vicinity. This localized connection approach reduces data transfer complexity for each base unit while the network of base units collectively provides complete area coverage.
