Radar-Integrated Assist Grip for Passenger Presence Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicles require a separate component or expose the radar device internally, compromising the external appearance and requiring additional manufacturing efforts to install the radar device for passenger presence detection.
Innovation Solution
An assist grip with a built-in radar member that senses passenger presence, coupled to the vehicle interior and rotatable, allowing convenient installation and improved aesthetics by integrating the radar functionality within a functional grip component.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a separate component is manufactured or the radar device is exposed inside the vehicle, then passenger presence detection function is achieved, but external appearance is compromised and additional manufacturing efforts are required
Solution Approach 1:
The patent combines the radar device with the assist grip into a single integrated component. The radar member is housed within the grip part, which serves both as a functional grip for passengers and as a mounting structure for the radar device. This merging eliminates the need for separate radar components and their associated mounting hardware, thereby reducing overall system complexity while maintaining passenger presence detection capability.
Solution Approach 2:
The assist grip is designed to serve multiple functions: it provides a gripping handle for passenger safety and convenience, and simultaneously houses the radar device for passenger presence detection. The grip part acts as both a mechanical component for user interaction and a structural housing for the electronic radar system, demonstrating multi-functionality that reduces the total number of components needed in the vehicle interior.
2Adaptability or versatility
If a separate component is manufactured for installing the radar device, then radar functionality is achieved, but manufacturing cost and installation complexity increase
Solution Approach 1:
The radar device is integrated into the assist grip structure, where the grip part serves as the housing for the radar member. This eliminates the need for separate mounting brackets, fasteners, and installation procedures that would be required if the radar were installed as a distinct component. The assist grip itself becomes the installation structure, simplifying both manufacturing and installation processes.
3Adaptability or versatility
If the radar device is exposed in the interior, then passenger presence detection is enabled, but aesthetic appearance is degraded
Solution Approach 1:
The radar member is nested within the grip part, which provides a cosmetic housing that conceals the electronic components. The grip part serves as an outer shell that encloses the radar device, presenting a clean, aesthetic interior surface while still allowing the radar to perform its detection function. This nesting arrangement hides the technical components behind a design-friendly exterior.
