Dual-Rotating Mount Structure for Compact Vehicle-Mounted Cameras
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing moving body mounted devices, such as driving recorders, are large in size and lack the ability to be attached to different surfaces of a moving body while allowing for changeable orientation of the optical axis, compromising usability.
Innovation Solution
A moving body mounted device with a body, first and second attachment portions, and a fixture that allows independent rotation of these portions about an axis, enabling attachment to various surfaces and adjustable orientation without increasing device size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the base is made rotatable in a wide range in the forward/backward direction relative to the body, then the orientation adjustability is improved, but the device size increases
Solution Approach 1:
The attachment structure is divided into two separate attachment portions (first and second attachment portions) positioned at different locations on the body. Each attachment portion can be independently rotated and fixed, allowing the device to adapt to different mounting surfaces and orientations without requiring a single large-range rotational mechanism, thus maintaining compact size while achieving versatility.
2Adaptability or versatility
If the device is designed to be attached to different surfaces of the moving body, then the usability is improved, but the structural complexity increases
Solution Approach 1:
The device incorporates two attachment portions that can be used in various combinations - both can be attached to the same surface for enhanced stability, or to different surfaces for orientation adjustment. This universal attachment capability allows a single device structure to serve multiple mounting scenarios without requiring complex specialized mechanisms for each case.

AI summary
A moving body mounted device includes: a body; a first attachment portion arranged on a first side in a first direction relative to the body, and attachable to a first attachment target member of a moving body; a second attachment portion arranged on a second side opposite to the first side in the first direction relative to the body, and attachable to a second attachment target member of the moving body; and a fixture for fixing the first attachment portion, the body, and the second attachment portion to each other. The first attachment portion and the second attachment portion are independently rotatable about an axis extending in the first direction relative to the body. The fixture enables each of the first attachment portion and the second attachment portion to be fixed in a desired rotational position relative to the body.
