Pivotal Vehicle Detection Unit Bracket Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle detection unit attachment structures, such as the sliding and inserting method disclosed in International Publication No. WO 2015/072289, may not be adaptable to all detection unit structures and installation positions, necessitating an alternative attachment method.
Innovation Solution
A detection apparatus with a detection unit that includes a front, back, and side surface portion, and a bracket with a bottom wall and guiding portions, allowing the detection unit to be pivotally attached by diagonally inserting one end into the bracket and pivoting about that end as a rotation center, with guiding and positioning features to secure the unit's position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a sliding and inserting attachment structure is used for the detection unit, then the attachment can be simple and quick, but the structure may not be adaptable to all detection unit types and installation positions
Solution Approach 1:
The patent transitions from a static sliding insertion structure to a dynamic pivotal attachment structure. The detection unit is attached by pivoting about one end as a rotation center, allowing the attachment to adapt to different detection unit geometries and installation positions while maintaining operational simplicity.
Solution Approach 2:
The bracket is divided into functional portions: a bottom wall portion for support, side wall portions for guidance, and engaging portions for securing the detection unit. This segmentation allows each portion to be optimized for its specific function while collectively providing versatile attachment capability.
2Adaptability or versatility
If the detection unit is diagonally inserted and pivoted for attachment, then adaptability to various configurations is improved, but the attachment process becomes more complex
Solution Approach 1:
The patent introduces a rotational dimension to the attachment process. Instead of linear insertion only, the detection unit pivots about one end as a rotation center, adding a rotational degree of freedom that enables accommodation of various component configurations without significantly increasing structural complexity.
Solution Approach 2:
The bracket acts as an intermediary structure with guiding portions that facilitate the pivotal attachment. The guiding portions constrain the motion path during pivoting, making the complex attachment process manageable while maintaining adaptability to different detection unit configurations.
3Manufacturing precision
If guiding portions are added to restrict position during pivoting, then positioning accuracy is improved, but the bracket structure becomes more complex
Solution Approach 1:
The bracket incorporates localized guiding portions at specific locations rather than throughout the entire structure. These guiding portions are strategically positioned to constrain the detection unit during pivotal attachment, providing necessary positioning accuracy while minimizing overall structural complexity.

AI summary
A detection apparatus includes a detection unit configured to detect a peripheral environment of a vehicle and a bracket configured to attach the detection unit to a vehicle body. The detection unit includes a front surface portion, a back surface portion, and side surface portions. The bracket includes a bottom wall portion and a first guiding portion configured to guide the attachment of the detection unit to the bracket. When the detection unit is attached to the bracket by diagonally inserting one end of the detection unit towards the bottom wall portion and pivoting the detection unit about a side of the one end as a rotation center, the first guiding portion restricts a position of the one end.
