Sensor Bracket Wall Surface for Stable Camera Separation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sensor brackets for on-board cameras are unstable in the up-down direction and require a large workspace for dismounting, as they rely on a flat spring that biases the camera only in the front direction, necessitating movement in two directions for removal.
Innovation Solution
A sensor bracket design that includes a wall surface within the bracket body to prevent the sensor from sliding excessively during dismounting, allowing for safe and easy separation by sliding the sensor along the bracket body, with a finger contact portion on the rear side to facilitate easy force application and a bottom-plate spring for stable mounting.

Engineering Contradiction Analysis
1Stability of the object's composition
If a flat spring is used to bias the on-board camera body only in the front direction, then the camera body can be mounted and fixed to the bracket, but the camera body becomes unstable in the up-down direction
Solution Approach 1:
The bracket structure is segmented into multiple functional components: a mounting plate for attachment, a holding portion with engagement protrusions for securing the camera, and a guide portion with wall surfaces for directional guidance. This segmentation allows each component to perform its specific function independently, providing stability without requiring an overly complex integrated structure.
Solution Approach 2:
The guide portion introduces a vertical dimension (up-down direction) to the mounting mechanism by providing wall surfaces that extend in the vertical direction. These wall surfaces guide the camera body during installation and prevent excessive movement in the up-down direction, adding dimensional control without significantly increasing overall structural complexity.
2Ease of operation
If the on-board camera is moved in two directions (rearward and downwards) for dismounting, then the camera can be separated from the bracket, but a relatively large work space is needed
Solution Approach 1:
Instead of requiring the camera to be pushed in multiple directions for removal, the engagement protrusions are designed to be pressed inward toward the bracket body. This inverted approach allows the camera to be detached by applying force in the opposite direction of engagement, simplifying the dismounting operation and reducing the workspace required.
Solution Approach 2:
The engagement protrusions are extracted as separate, movable elements within the holding portion. These protrusions can be independently pressed inward to release the camera body, allowing for a simplified single-direction removal operation rather than requiring complex multi-directional movement of the entire camera assembly.
3Ease of operation
If the sensor is detached by sliding along the bracket body without a wall surface, then the separation process is simple, but the sensor may move out with momentum and cause safety issues
Solution Approach 1:
The wall surfaces of the guide portion perform preliminary action by guiding the camera body during the sliding removal process. These surfaces prevent excessive movement and control the separation trajectory before the camera is fully detached, ensuring safe and controlled removal without requiring complex additional safety mechanisms.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables safe and easy separation of the sensor from the bracket even in confined spaces, preventing unnecessary stress on the flat springs and maintaining the camera's field of view without obstructing the lens, thus enhancing operational safety and convenience.
Implementation Method 1
the on-board camera main body is biased towards the front by the flat spring
Implementation Method 2
a wall surface is provided in the bracket body, the wall surface preventing the sensor to proceed in a sliding direction by having a portion of the sensor abut thereagainst

AI summary
A sensor bracket includes a bracket on which a camera that detects a state around a vehicle is mounted, and a planar portion of the bracket that holds the camera to the bracket by engaging with an engagement protrusion of the camera. The camera is detached by being slid against the bracket. The bracket is provided with a vertical rib that prevents the camera front proceeding in a sliding direction by having a portion of the camera abut thereagainst in the course of the camera moving from a mounted state to a separated state.
