Optical Sensor Disposition for Saddle Riding Vehicle Appearance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Optical sensor disposition structures for saddle riding vehicles face a trade-off between maintaining detection region and improving appearance characteristics, as visible installation degrades aesthetics but hidden installation narrows the field of vision.
Innovation Solution
An optical sensor disposition structure that includes an airflow guide member covering the front section of the vehicle body, with an introduction port to guide air rearward, and an optical sensor positioned to overlap this port in a front view, along with a second airflow guide member forming an airflow path and a lens on the boundary section between the members, which is recessed and overlaps the airflow guide member in a side view, ensuring the sensor is not easily visible.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the optical sensor is installed on a central portion of a window screen, then the detection region is maintained, but appearance characteristics are degraded because the camera is easily seen from the outside
Solution Approach 1:
The patent repositions the optical sensor from a central front-facing location to a lateral position where it overlaps the introduction port in front view. This dimensional relocation allows the sensor to be obscured by the airflow guide member from the front, improving appearance while maintaining detection capabilities through the port opening.
Solution Approach 2:
The introduction port serves as an intermediary element that allows the optical sensor to be positioned laterally while still providing forward detection capability. The port acts as a window through which the sensor can detect objects while being visually concealed by the airflow guide member from the front view.
2Shape
If the optical sensor is installed at a position that cannot be easily seen from the outside, then appearance characteristics are improved, but the field of vision is narrowed
Solution Approach 1:
The patent utilizes the vertical dimension by positioning the optical sensor to overlap the introduction port in front view. This allows the sensor to be concealed behind the airflow guide member from the front while maintaining an unobstructed field of vision through the port opening, effectively resolving the contradiction between appearance and detection capability.
Solution Approach 2:
The introduction port creates a localized opening in the airflow guide member that provides a clear detection path for the optical sensor. This local quality change allows the sensor to have an unobstructed field of vision through the port while the rest of the guide member conceals the sensor from external view, improving appearance without sacrificing detection capability.
3Shape
If the lens is disposed on the boundary section between airflow guide members, then the optical sensor is more difficult to visually recognize, but device complexity increases
Solution Approach 1:
The patent integrates the lens directly into the boundary section between the first and second airflow guide members, merging the optical component with the structural elements. This integration approach conceals the lens within the existing structure, making it more difficult to visually recognize while avoiding the need for separate mounting mechanisms, thereby limiting the increase in device complexity.
