Camera Device Guard Member with Rotating Projecting Part
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Camera devices installed on vehicles, especially buses, face challenges in maintaining a sufficient rearward visual field while being protected from external impacts, as guard portions can limit the visual field when mounted on the rear part of the vehicle.
Innovation Solution
A camera device design featuring a guard member with a projecting part that can be positioned either outside or inside the lens cover depending on the mounting location, ensuring protection from impacts without obstructing the visual field, by being further outside when mounted on the side and closer to the vehicle when mounted on the rear.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a guard portion is provided to protect the lens cover from roadside trees or the like, then the lens cover is protected from external impact, but the rearward visual field is limited when the camera is installed on the rear part of the vehicle
Solution Approach 1:
The guard member is designed with a rotatable projecting part that can change its position between a first state (extending outward to protect the lens cover) and a second state (retracted to not limit the visual field). This dynamic adjustment allows the same structure to serve different functions depending on the mounting location and operational requirements.
Solution Approach 2:
The guard member is divided into a main body and a separable projecting part. The projecting part can be independently positioned in different states, allowing the protection function to be activated only when needed (side mounting) while minimizing visual field limitation (rear mounting).
2Reliability
If the camera is designed with a guard member for side mounting protection, then robustness against contact with roadside trees is improved, but design uniformity across different vehicle locations is compromised
Solution Approach 1:
The guard member with a rotatable projecting part serves multiple functions: it provides robust protection when mounted on the side of the vehicle, and it can be retracted to maintain aesthetic uniformity when mounted on the rear. This multi-functional design allows a single structure to meet different requirements at different mounting locations.
3Object-affected harmful factors
If the projecting part is disposed further outside the lens cover for side mounting, then protection from impact is enhanced, but the visual field is obstructed when mounted on the rear part
Solution Approach 1:
The projecting part of the guard member is designed to be rotatable, allowing it to dynamically adjust its position. In the first state, it extends further outside the lens cover to maximize impact protection for side mounting. In the second state, it rotates to a retracted position that does not obstruct the visual field for rear mounting, thus eliminating the trade-off between protection and visual field coverage.

AI summary
Disclosed is a camera device including: a camera body; a transparent lens cover configured to cover a lens portion of the camera body; and a guard member configured to protect the lens cover from external impact, in which a projecting part is formed in the guard member, and when the camera device is mounted on a target object, the camera device is in a first state in which the lens cover is disposed between the projecting part of the guard member and the target object, or is in a second state in which the projecting part of the guard member is disposed between the lens cover and the target object.
