Taillight Housing Integration for Straddle Vehicle Radar Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Straddle type vehicles face erroneous detection issues when using detection units to sense conditions behind the vehicle due to interference from non-target objects and the road surface, which are not effectively addressed by existing detection devices.
Innovation Solution
The detection unit is integrated within the taillight housing, positioned to avoid interference from non-target objects and the road, with a design that separates light and radio wave transmission regions, ensuring accurate detection and protection from environmental factors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the detection unit is positioned behind the vehicle to detect surrounding conditions, then the detection coverage is improved, but erroneous detection from non-target objects and road surface interference increases
Solution Approach 1:
The detection unit is extracted from the conventional position behind the vehicle and relocated inside the taillight housing. This extraction removes the detection unit from the interference zone of non-target objects and road surface, eliminating the harmful factors while preserving detection functionality.
Solution Approach 2:
The taillight housing serves as an intermediary structure that houses the detection unit. The housing acts as a protective mediator that shields the detection unit from environmental interference while allowing radio waves to pass through for detection operations.
2Reliability
If the detection unit is integrated inside the taillight housing, then protection from environmental factors is improved, but the complexity of housing design increases
Solution Approach 1:
The taillight housing is designed to serve multiple functions: its original function of housing and protecting the light source, and a new function of housing and protecting the detection unit. This multi-functionality provides environmental protection without adding separate protective structures, thereby avoiding increased complexity.
Solution Approach 2:
The detection unit is merged with the taillight housing structure. Instead of creating a separate protected enclosure for the detection unit, the design combines it with the existing housing, reducing overall structural complexity while maintaining protection.
3Illumination intensity
If the housing has an uneven shape to diffuse light, then light distribution is improved, but the structure becomes more complex
Solution Approach 1:
The housing is designed with local quality variation: the light-emitting portion has an uneven shape for optimal light diffusion, while the detection unit portion maintains a simple flat structure. This localized application of complexity only where needed achieves good light distribution without unnecessarily complicating the entire housing structure.
