Vehicle Camera Mounting Structure with Angled Biasing Surfaces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic device mounting structures for vehicles, such as cameras and sensors, face challenges in preventing rattling while maintaining a sufficient mounting space for other components, as they often require multiple springs that occupy valuable space.
Innovation Solution
An onboard electronic device mounting structure that includes a base fixed to the vehicle window with a biased portion and an engagement portion, utilizing a biasing member to apply force in one direction and supporting surfaces at different angles to prevent rattling, while minimizing space usage by reducing the need for separate biasing members and allowing for easier installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple springs are used to prevent rattling in different directions, then the rattling prevention is improved, but the mounting space for other components is reduced
Solution Approach 1:
The patent combines multiple biasing functions into a single biasing member by providing it with multiple biasing portions that extend in different directions. Each biasing portion provides elastic biasing force in a different direction, replacing the need for multiple separate springs while maintaining comprehensive rattling prevention and preserving mounting space.
2Reliability
If multiple separate biasing members are used to provide biasing force in different directions, then the rattling prevention is improved, but the device complexity increases
Solution Approach 1:
The patent merges multiple biasing members into a single integrated biasing member with multiple biasing portions. This single component provides biasing forces in multiple directions simultaneously, reducing the total number of components and simplifying the overall device structure while maintaining effective rattling prevention.
Solution Approach 2:
The biasing member is designed to perform multiple functions simultaneously - it provides elastic biasing force in multiple different directions through its multiple biasing portions, making it a multi-functional component that replaces several single-function components.

AI summary
Provided is an onboard electronic device mounting structure that prevents rattling of the electronic device, and does not unduly limit the mounting space for other components. The mounting structure (1) secures a camera (2) to a window (W) of a vehicle via a mounting device (3). An engagement portion (14) provided in a front end side of the camera abuts against a base (8) of the mounting device, and a biased portion including a columnar member provided on a lateral side of the camera is supported by the base. A biasing member (18) of the base biases the biased portion against a supporting portion (17) of the base. The supporting portion is provided with two supporting surfaces (17a and 17b) which support the biased portion with two reaction forces each at an angle to the direction of the biasing force of the biasing member.
