Camera Flash Mechanism Two-Axis Rotation Lens Blockage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Imaging devices with a flash mechanism face the issue of flash light being blocked by a lens unit when the light emitting component pops up, limiting the range of flash emission.
Innovation Solution
The design includes a flash mechanism with a first arm and a second arm that rotate around distinct axes, allowing the flash light emitter to extend in a way that minimizes blockage by the lens unit, with specific rotational positions that adjust the orientation of the flash light emission to avoid obstruction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the light emitting component pops up from storage space, then the flash mechanism can emit light, but the flash light may be blocked by the lens unit
Solution Approach 1:
The patent introduces a two-stage rotation mechanism where the first arm rotates around a first axis and the second arm rotates around a second axis that is offset from the first axis. This dimensional arrangement allows the flash light emitter to achieve positions that avoid blockage by the lens unit, transforming a one-dimensional pop-up motion into a two-dimensional rotational workspace.
Solution Approach 2:
The flash mechanism employs dynamic rotational joints that allow the arms to change orientation during operation. The first arm can rotate to different angular positions, and the second arm can independently rotate relative to the first arm, enabling the system to dynamically adjust the flash emitter's position and orientation to avoid lens blockage.
2Illumination intensity
If the flash mechanism extends outwardly from interior space, then flash light can be emitted, but the range of flash emission is limited
Solution Approach 1:
By implementing a two-axis rotation system instead of a simple linear extension, the flash mechanism gains access to a three-dimensional workspace. The first rotation around the first axis and the second rotation around the offset second axis create spherical coordinate-like positioning, dramatically expanding the angular coverage and emission range compared to a single-axis mechanism.
Solution Approach 2:
The flash mechanism is divided into segmented components: a first arm with a first rotation joint, a second arm with a second rotation joint, and a light emitting component. This segmentation allows each segment to rotate independently around its respective axis, enabling complex positioning and broader emission coverage than a monolithic structure could achieve.

AI summary
An imaging device includes an optical system, a camera housing defining an opening with an interior storage space, and a flash mechanism connected to the housing. The flash mechanism is movable between an exposed state and an unexposed state. The flash mechanism has a first arm, a second arm, and a light emitting component attached to the second arm. The first arm is located at a first rotational position in the exposed state and is configured to rotate around a first axis located within the interior space. The second arm is located at a third rotational position in the exposed state and is configured to rotate with respect to the first arm around a second axis located closer to the subject than the first axis in the exposed state.
