Strobe Mechanism Capacitor Nesting to Prevent Vignetting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing strobe mechanisms in imaging devices often suffer from vignetting of light rays due to the lens barrel, which limits their compactness and functionality.
Innovation Solution
A strobe mechanism that includes a base member, a slide member, a strobe part, and a capacitor, where the strobe part pops up from a stored state using a slide and rotation mechanism, with the capacitor arranged in a hollow region defined by the slide member to minimize vignetting and device size.

Engineering Contradiction Analysis
1Object-affected harmful factors
If the strobe mechanism uses a conventional arrangement with the capacitor outside the slide member, then the device structure is simpler, but the lens barrel causes vignetting of strobe light rays
Solution Approach 1:
The capacitor is nested within the hollow region defined by the slide member walls, allowing the capacitor to be positioned inside the moving assembly rather than outside. This nesting arrangement eliminates the need for separate mounting space for the capacitor and prevents the lens barrel from obstructing the strobe light path, thereby resolving the vignetting issue without significantly increasing structural complexity
2Object-affected harmful factors
If the capacitor is arranged in the hollow region of the slide member, then vignetting is avoided, but the space for component arrangement becomes more constrained
Solution Approach 1:
The capacitor is positioned in the hollow region formed by the slide member walls, utilizing the vertical and lateral space within the slide assembly rather than arranging components in a planar configuration. This three-dimensional arrangement optimizes space utilization and prevents vignetting by ensuring the capacitor does not obstruct the strobe light path

AI summary
The present disclosure provides a strobe mechanism which has a compact constitution thus avoiding vignetting of strobe light rays by a lens barrel. According to one aspect of the present disclosure, there is provided a strobe mechanism which brings a strobe into a use state by making the strobe pop up from a stored state. The strobe mechanism includes: a base member; a slide member held in a movable manner in one direction with respect to the base member; a strobe part which is mounted on the slide member; and a capacitor which supplies electricity to the strobe part; and the capacitor is arranged in a region defined by walls of the slide member.
