Solution Overview
Problem
Existing motor vehicle control systems face challenges in optimizing the functional scope of positioning units within limited installation space, leading to inefficiencies in sensor information usage and increased space requirements due to separate installation needs for different positioning technologies like radar and Bluetooth units.
Innovation Solution
Combining radar sensor units and Bluetooth wireless units into a unified positioning module, sharing installation space and circuitry, with careful frequency separation to prevent interference, allowing for simultaneous operation and reduced installation space needs while leveraging complementary acquisition characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate installation spaces are allocated for different positioning units (radar, Bluetooth), then each unit can operate independently, but the total installation space requirements increase significantly
Solution Approach 1:
The patent combines multiple positioning units (radar sensor unit, Bluetooth wireless unit, and other positioning units) into a single integrated positioning module. This merging allows all units to share a common installation space and reference point, significantly reducing the total installation area while maintaining independent operational capabilities through electronic integration rather than physical separation.
Solution Approach 2:
The integrated positioning module serves multiple functions simultaneously - it performs radar-based distance profiling, Bluetooth-based user identification and authentication, and other positioning functions all through a single multi-functional unit. This universal design eliminates the need for separate dedicated spaces for each function while maintaining all required capabilities.
2Area of stationary object
If multiple positioning units are integrated into a single module, then installation space is reduced, but frequency interference between units may occur
Solution Approach 1:
The patent addresses frequency interference by carefully selecting and spacing apart the operating frequencies of different positioning units. The radar unit operates at approximately 79 GHz while the Bluetooth unit operates at approximately 2.4 GHz. This parameter change in frequency selection creates sufficient separation to prevent harmful interference while allowing both units to coexist in the same physical installation space.
3Device complexity
If different positioning units use identical reference points, then conversion calculations between sensor information are simplified, but the design complexity increases
Solution Approach 1:
The patent merges all positioning units into a single integrated module that shares a common reference point for all sensing operations. This merging eliminates the need for complex conversion calculations between different reference frames that would be required if separate units used different reference points. The common reference point simplifies data processing while the modular integrated design manages the manufacturing complexity.
