Solution Overview

Problem

Existing motorcycle radar systems divert the driver's attention from the road by requiring them to look at rear-view mirrors for visual warnings, posing a safety risk, especially on busy roads.

Innovation Solution

A radar device that illuminates a portion of the dashboard monitor to provide visual alerts about vehicles in blind spots and approaching zones without requiring the driver to look away from the road, using sensors and controllers to determine the illumination based on vehicle presence and speed.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a radar device is mounted on a motorcycle to enable automated driving functions, then safety and automated driving capability are improved, but device complexity and integration challenges increase

Engineering Contradiction:
ImprovesafetyVSAvoidintegration complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The radar device is integrated into the motorcycle's headlight assembly, combining two separate functional components (radar system and lighting system) into a single unified structure. This merging approach reduces overall system complexity by eliminating separate mounting requirements and shared structural real estate, while maintaining both radar detection capabilities and headlight functionality.

Inventive Principle:
Principle #5Merging (Combining)

2Object-generated harmful factors

If the radar device is integrated into the headlight assembly, then aerodynamics and design cleanliness are improved, but manufacturing complexity and assembly difficulty increase

Engineering Contradiction:
ImproveaerodynamicsVSAvoidassembly difficulty
Core Design Contradiction:
Object-generated harmful factorsVSEase of manufacture

Solution Approach 1:

The headlight assembly is divided into distinct functional modules: the headlight housing, the radar device, and the turn signal assembly. These segmented components are designed to be assembled together through standardized interfaces, allowing for modular manufacturing and simplified assembly processes while maintaining the aerodynamic benefits of integration.

Inventive Principle:
Principle #1Segmentation

3Measurement precision

If the radar device is exposed on the motorcycle, then detection capability is improved, but susceptibility to damage from road debris and environmental factors increases

Engineering Contradiction:
Improvedetection capabilityVSAvoiddamage susceptibility
Core Design Contradiction:
Measurement precisionVSObject-affected harmful factors

Solution Approach 1:

The radar device is nested within the protected environment of the headlight assembly housing, which shields it from road debris, weather elements, and physical damage. The radar antenna is positioned within the headlight structure rather than being externally exposed, maintaining detection capabilities while providing mechanical protection through the integrated housing design.

Inventive Principle:
Principle #7Nested doll (Nesting)

AI summary

The present invention relates to a motorcycle comprising a radar device configured to detect, for each side of said motorcycle (1), the presence of a vehicle near or approaching in at least a first zone (BSD, BSD') characteristic of its blind spot and in at least a second zone (LCA, LCA') adjacent to and behind said first zone (BSD, BSD') with respect to the direction of travel of said motorcycle (1). The radar device (16) comprises at least one sensor (161) and at least one controller (162) that determines the presence of said vehicle in one of said zones (BSD, BSD, LCA, LCA') based on a signal sent by said sensor element (161). According to the invention, the controller (162) is connected, directly or indirectly, to a monitor (13) of the dashboard (12) of the motorcycle (1) and determines the illumination of at least one predetermined portion (131, 131', 132, 132') of said monitor (13) when it detects the presence of said vehicle in one of said zones (BSD, BSD', LCA, LCA').
