Motorcycle Rear Radar Cover Layout for Mud-Safe Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing motorcycle radar devices are exposed and prone to water and mud splashes, and may have their electromagnetic wave transmission obstructed by the front wheel, leading to reduced functionality.
Innovation Solution
The rear radar device is covered by a material that transmits electromagnetic waves, similar to the headlight and taillight, which shields it from water and mud while maintaining its operational range and avoiding interference from the motorcycle's frame and other components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the radar device is arranged exposed outward, then the transmission/reception range of electromagnetic wave is secured, but water and mud may be splashed on the radar device
Solution Approach 1:
A cover member made of electromagnetic wave-transmitting material is introduced as an intermediary between the radar device and the external environment. This cover member allows electromagnetic waves to pass through while protecting the radar device from water and mud splashes. The headlight and taillight act as additional intermediary elements that shield the radar device without blocking its detection function.
Solution Approach 2:
The cover member is designed as a thin, flexible structure that can be positioned between the radar device and external elements. This thin film approach allows electromagnetic waves to penetrate effectively while providing sufficient protection against water and mud. The flexible nature allows it to be integrated into the motorcycle's existing structure.
2Object-affected harmful factors
If the radar device is covered by a material, then protection from water and mud is improved, but electromagnetic wave transmission may be obstructed
Solution Approach 1:
The cover member is designed with specific local properties: it is made of material that is transparent to electromagnetic waves while providing protection against water and mud. The headlight and taillight are positioned specifically to shield the radar device without blocking the transmission/reception portion. This localized quality approach ensures protection is provided only where needed without compromising electromagnetic wave transmission.
Solution Approach 2:
The solution employs composite material properties where the cover member combines water/mud resistance with electromagnetic wave transparency. The headlight and taillight also serve as composite structures that provide both lighting functions and protective shielding. This composite approach allows simultaneous achievement of protection and transmission.
3Object-affected harmful factors
If the radar device is positioned to avoid water splash, then protection is improved, but the transmission range may be reduced by frame obstruction
Solution Approach 1:
The cover member acts as an intermediary that allows electromagnetic waves to pass through while providing physical protection. The headlight and taillight serve as intermediary shielding elements that protect the radar device from water splash without blocking the transmission range, as they are positioned and designed to be transparent to the radar's electromagnetic waves.
Solution Approach 2:
The radar device is positioned in three-dimensional space to optimize both protection and transmission range. By utilizing vertical positioning (above the rear wheel) and horizontal positioning (rearward of the rear frame), the system achieves protection from water splash while maintaining clear transmission paths. This dimensional optimization allows simultaneous achievement of both goals.

AI summary
The motorcycle 1 includes a headlight 31, a taillight 46, and a rear radar device 62. The headlight 31 includes a part of material that shields the electromagnetic wave. The taillight 46 includes a part of material that shields the electromagnetic wave. The rear radar device 62 transmits a transmission wave, which is the electromagnetic wave for detecting the surroundings, from a transmission/reception portion, and receives a reflected wave in which the transmission wave is reflected on an object, at the transmission/reception portion. The transmission/reception portion of the rear radar device 62 is covered by a member with a material that transmits the electromagnetic wave, at least in a range where the transmission wave is transmitted. The rear radar device 62 is arranged outside a rear projection device of the taillight 46, in the rear view.
