In-Vehicle Camera Bracket Structure for Easier Casing Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing structures for fixing a camera casing to a vehicle interior windshield are difficult to attach due to obscured fixing points, making the process challenging for workers.
Innovation Solution
A casing attaching method and structure that includes a fulcrum support structure, inclined surface structure, and shaft fixing structure, where the casing has a fulcrum rod and shafts that are guided and fixed by the bracket's inclined surfaces and spring pieces, facilitating the attachment process by guiding and securing the shafts and fulcrum rod.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional casing fixing structure is used, then the camera can be fixed to the windshield, but the fixing location becomes difficult for workers to see and the attachment process becomes difficult
Solution Approach 1:
The patent introduces a bracket as an intermediary component between the casing and the windshield. The bracket includes guide ribs that extend toward the windshield, providing visible guidance for workers during attachment. The guide ribs act as visual mediators that make the fixing location easily identifiable while the bracket itself handles the actual fixation function, separating the guidance function from the fixing function.
2Ease of manufacture
If the casing structure is simplified, then manufacturing becomes easier, but the attachment process becomes more difficult due to lack of guidance structures
Solution Approach 1:
The patent divides the attachment system into separate functional components: the casing maintains its simple structure for easy manufacturing, while the bracket is segmented into a base portion and guide ribs. The guide ribs are provided in plurality and extend in specific directions to provide visual and physical guidance during attachment. This segmentation allows the casing to remain simple while the bracket handles the complexity of guidance and fixation.
3Ease of operation
If the fixing structure is made more complex with additional guidance components, then attachment becomes easier, but the device complexity increases
Solution Approach 1:
The bracket is designed to perform multiple functions: it provides structural support for the casing, offers visual guidance through guide ribs, and enables attachment to the windshield. The guide ribs serve both as visual indicators for workers and as physical guides that align the casing during attachment. This multi-functionality reduces the need for separate dedicated guidance components, thereby limiting the increase in overall device complexity.
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
This method simplifies the attachment of the in-vehicle camera by providing clear visual guidance and secure fixation, ensuring easy and accurate placement of the camera casing on the bracket.
Implementation Method 1
a fulcrum spring piece that extends in the front-rear direction inside the reception hole and comes into contact with the fulcrum rod
Implementation Method 2
a shaft spring piece that is attached to the bracket and urges the shaft between the shaft spring piece and the arm portion
Implementation Method 3
an inclined surface structure that guides the shaft forward and guides the shaft toward the bracket when the casing faces forward and the casing is attached to the bracket

AI summary
An in-vehicle camera fixing structure includes a casing that supports an in-vehicle camera, and a bracket that holds the casing below. The casing includes a fulcrum rod protruding forward, and a left shaft and a right shaft supported above the casing and extending in a lateral direction. The bracket includes a fulcrum support structure that swingably supports the fulcrum rod, left and right temporary shaft placement pieces, and left and right shaft fixing structures that fix the left shaft and the right shaft in front of the left and right temporary shaft placement pieces, respectively. When the casing is directed forward and the casing is attached to the bracket, the left and right temporary shaft placement pieces guide the left shaft and the right shaft forward, and guide the left shaft and the right shaft toward the bracket.
