Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing optical devices experience increased current consumption in the drive source due to interference between the anti-vibration mechanism and fixation mechanism during switching states, which is not addressed by continuous oscillation based on sensor detection.
Innovation Solution
An optical device with a processor that controls the drive source to prevent interference between the anti-vibration mechanism and fixation mechanism by adjusting the driving force based on sensor detection, using a gimbal structure and fixation mechanism to manage the switching states.

Engineering Contradiction Analysis
1Reliability
If the anti-vibration mechanism is caused to continuously oscillate based on sensor detection, then vibration correction is maintained, but current consumption in the drive source increases due to interference between the anti-vibration mechanism and fixation mechanism during switching states
Solution Approach 1:
The patent applies periodic action by controlling the anti-vibration mechanism to oscillate only during photographing operations rather than continuously. The control unit determines whether the imaging apparatus is in a photographing state and activates the anti-vibration mechanism only when needed, avoiding continuous operation that would cause interference with the fixation mechanism during switching states.
Solution Approach 2:
The patent implements dynamics by making the anti-vibration mechanism's operation state changeable based on operational conditions. The mechanism transitions between active oscillation states and inactive states depending on whether the apparatus is photographing or not, allowing the system to adapt its behavior to current operational requirements and avoid unnecessary energy consumption.
2Manufacturing precision
If the fixation mechanism switches between fixation state and release state, then positioning control is achieved, but interference occurs between the specific portion of the anti-vibration mechanism and the fixation mechanism
Solution Approach 1:
The patent applies preliminary action by having the control unit determine the operational state (photographing or not) before activating the anti-vibration mechanism. This preliminary determination allows the system to coordinate the switching of the fixation mechanism with the activation of the anti-vibration mechanism, ensuring that the specific portion of the anti-vibration mechanism does not interfere with the fixation mechanism during state transitions.

AI summary
An optical device which includes an optical system includes a sensor that detects vibration on the optical device, an anti-vibration mechanism that includes a drive source driven based on a result of detection performed by the sensor, a fixation mechanism that fixes a position of the anti-vibration mechanism by coming into contact with a specific portion of the anti-vibration mechanism, and a processor that performs control with respect to the drive source such that interference between the specific portion and the fixation mechanism does not occur while the fixation mechanism is switching from one of a fixation state, in which the fixation mechanism fixes the position of the anti-vibration mechanism, and a release state, in which the fixation state of the fixation mechanism is released, to the other of the fixation state and the release state.
