Sensor Bracket with Detachable Spring and Tool Restriction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sensor bracket systems for on-board cameras are unstable in the up-down direction due to the integral flat spring design, requiring replacement of the entire bracket when the spring fails, and pose a risk of damaging the windshield during spring replacement.
Innovation Solution
A sensor bracket with a detachable spring member and a displacement restriction portion that receives the tool, preventing it from hitting the windshield, allowing safe and easy replacement of the spring without damaging the windshield.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the flat spring is integral with the bracket, then the bracket structure is simple, but when the spring fails, the entire bracket must be replaced
Solution Approach 1:
The bracket is divided into separate components: the bracket body and the flat spring are made as detachable parts rather than an integral structure. The flat spring is designed as a separate replaceable component that can be independently removed and replaced without replacing the entire bracket, thus resolving the contradiction between structural simplicity and ease of repair.
2Ease of operation
If a tool is used to press the spring member for replacement, then the spring can be installed, but the tool may hit the windshield and cause damage
Solution Approach 1:
A displacement restriction portion is introduced as an intermediary structure between the tool and the windshield. This restriction portion limits the movement range of the tool during spring installation, preventing the tool from contacting and damaging the windshield while still allowing the installation operation to be performed.
3Device complexity
If the flat spring biases the camera only in the front direction, then the mounting mechanism is simple, but the camera becomes unstable in the up-down direction
Solution Approach 1:
The flat spring is designed to extend in multiple directions rather than solely in the front direction. By extending the spring in lateral directions as well, it provides biasing forces in multiple dimensions, thereby stabilizing the camera in the up-down direction and other directions while maintaining a relatively simple mounting mechanism structure.
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
The solution provides a stable mounting system for on-board cameras by using a detachable spring member and a displacement restriction portion, enabling safe and easy replacement of the spring, preventing damage to the windshield and ensuring the camera remains securely attached.
Implementation Method 1
a spring member provided in the bracket body, the spring member abutting against the sensor and biasing in a direction that maintains a mounted state of the sensor

AI summary
A sensor bracket includes a bracket on which a camera that detects a state around a vehicle is mounted, a flat spring that abuts against the camera and biasing in a direction that maintains a mounted state of the camera when the camera is mounted on the bracket, and a recess that receives a portion of a tool and restricts a displacement range of the tool when the flat spring is pressed by the tool and is mounted on a projection for the spring of the bracket.
