Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If conventional parking space management systems use image processing and data calculations to determine vehicle presence, then measurement precision can be maintained, but device complexity increases significantly
Solution Approach 1:
The patent replaces complex image processing systems with a radio wave-based detection system. The communication apparatus transmits radio waves and detects vehicle presence through signal reflection and absorption characteristics, substituting mechanical/optical systems with electromagnetic wave-based detection that requires simpler hardware configuration.
Solution Approach 2:
The patent introduces radio waves as an intermediary medium to detect vehicle presence. Instead of directly processing images or sensor data, the system uses radio wave transmission and reflection patterns as an intermediate step to determine whether a parking space is occupied, simplifying the overall detection mechanism.
2Measurement precision
If simple detection methods are used to determine parking space occupancy, then device complexity is reduced, but measurement precision deteriorates
Solution Approach 1:
The communication apparatus performs multiple functions using a single system: it manages communication protocols, transmits data, and detects vehicle presence through radio wave interaction. This multi-functional approach eliminates the need for separate detection devices, achieving simple configuration without sacrificing detection accuracy.
Solution Approach 2:
The communication apparatus uses its own transmitted radio waves to detect vehicle presence. By analyzing the reflection and absorption of its own signals, the system achieves self-contained detection capability without requiring additional external sensors or complex multi-device coordination.
3Measurement precision
If beamforming technology is implemented to associate parking spaces with transmission directions, then measurement precision improves for space identification, but device complexity increases
Solution Approach 1:
The patent applies beamforming to create direction-specific radio wave transmission patterns, where each beam is localized to a specific parking space direction. This localizes the detection capability to specific spatial zones, enabling accurate parking space identification through directional signal characteristics without requiring complex omnidirectional systems.

AI summary
A parking space management method by a communication apparatus comprises transmitting, a radio signal beamformed in a specific direction, determining that a parking space associated with the specific direction is in a state of being vacant when the communication apparatus receives a response signal in response to the radio signal, and determining that the parking space is in a state of being occupied by a vehicle parked therein when the communication apparatus does not receive the response signal.
