Vehicle Sensor Bracket Layout for Precise Positioning and Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sensor brackets for vehicles lack precision in securing the position of sensors relative to the vehicle body, leading to potential detachment and inaccurate positioning.
Innovation Solution
A sensor bracket design featuring first and second positioning portions, pressing portions, and engaging portions that securely engage the sensor at multiple points, including coupling pieces, to ensure accurate and stable mounting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple engaging portions are provided on either side of positioning portions and pressing portions, then the sensor can be prevented from detaching, but the position of the sensor relative to bracket becomes less accurate
Solution Approach 1:
The bracket is divided into distinct functional regions: positioning portions (25) that provide precise lateral positioning, pressing portions (26) that apply force, and engaging portions (27) that secure the sensor. By segmenting these functions and arranging them in a specific sequence along the first direction, the patent achieves both secure attachment and accurate positioning.
Solution Approach 2:
The patent transitions from a symmetric bilateral arrangement to an asymmetric linear arrangement where engaging portions are positioned between positioning and pressing portions along the first direction. This dimensional reorganization optimizes the spatial relationship between components, allowing the sensor to be securely engaged at a location that maintains positioning accuracy.
2Manufacturing precision
If engaging portions are positioned between positioning portions and pressing portions along the first direction, then positioning accuracy is improved, but the structural complexity increases
Solution Approach 1:
Multiple functions are merged into a single integrated bracket structure. The positioning portions, pressing portions, and engaging portions are all formed as part of the same bracket component, which simplifies manufacturing and assembly while achieving the desired positioning accuracy through careful geometric design.
Solution Approach 2:
The bracket structure is designed to automatically position and secure the sensor through its geometric features without requiring additional adjustment mechanisms or complex assembly steps. The engaging portions naturally engage with the sensor at the correct position between the positioning and pressing portions.

AI summary
A sensor bracket (1) for mounting a sensor (2) to a vehicle body, comprising: a base wall (10) opposing a back surface of the sensor; a pair of first positioning portions (25) projecting from the base wall and abutting a side edge of the sensor from a first direction extending along the base wall; a pair of first pressing portions (26) projecting from the base wall and pressing the sensor against the first positioning portion in the first direction; and a first engaging portion (27) projecting from the base wall and engaging the sensor against a movement thereof away from the base wall, the first engaging portion being positioned between the first positioning portions and the first pressing portions along the first direction.
