Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If multiple radars are deployed to cover multiple detection spaces, then the detection coverage is improved, but the device complexity and information integration difficulty increase
Solution Approach 1:
The patent merges detection results from multiple radars by creating overlapping detection spaces and integrating their output data. The processor combines information from multiple radars to determine target object locations, merging what would otherwise be separate detection systems into a unified multi-space detection network that maintains simplicity while expanding coverage.
Solution Approach 2:
The detection device is designed with universal functionality to handle detection results from multiple radars simultaneously. The processor can process detection data from any radar in the network, determine target locations across multiple spaces, and provide unified output, making the system adaptable to various radar configurations and space arrangements.
2Area of stationary object
If multiple radars are deployed to cover multiple detection spaces, then the detection coverage is improved, but the difficulty of integrating information from multiple radars increases
Solution Approach 1:
The patent segments the detection space into multiple overlapping zones, each associated with a specific radar. By dividing the overall detection area into manageable segments with clear boundaries and overlap regions, the system simplifies information integration - each radar handles its own segment while shared overlap regions provide redundancy and enable seamless transitions between detection spaces.
Solution Approach 2:
The processor acts as an intermediary that receives detection results from multiple radars, processes and integrates this information, and produces unified location determination output. This intermediary component manages the complexity of information integration by standardizing how data from different radars is combined, making the integration process systematic rather than ad hoc.
3Device complexity
If a single radar is used to detect target object location, then the device complexity is reduced, but the detection range coverage becomes insufficient
Solution Approach 1:
The patent extends detection coverage by adding spatial dimensionality through multiple detection spaces rather than simply increasing the power or range of a single radar. By organizing detection areas into multiple overlapping zones in different spatial locations, the system achieves expanded coverage while keeping individual radar units simple and the overall architecture manageable.

AI summary
A multi-radar based detection device and detection method for a target object are provided. In the detection method, a first detection result corresponding to a first detection space and a second detection result corresponding to a second detection space are received. The first detection space entering a first status is determined in response to the first detection result indicating that the target object in the first detection space moves to an overlapping area between the first detection space and the second detection space. First information is output in response to determining that the first detection space enters the first status. The second detection space entering a second status is determined in response to the second detection result indicating that the target object not in the second detection space appears in the overlapping area. Second information is output in response to determining that the second detection space enters the second status.
