Optical Driver Controller Locking State Actuator Load
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Optical driver apparatuses face excessive load issues in actuators and transmission mechanisms when attached to optical apparatuses with locking mechanisms, as driving the actuator in a locked state generates excessive force.
Innovation Solution
An optical driver apparatus with a controller that determines the state of a locking mechanism and either drives the actuator or performs a warning operation based on the locking state, preventing excessive load by not driving the actuator when the mechanism is locked and providing a warning when the locking mechanism restricts motion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the actuator is driven when the locking mechanism is in a locking state, then the operation member can be driven, but excessive load is generated in the actuator and transmission mechanism
Solution Approach 1:
The controller checks the locking state before driving the actuator. If the locking mechanism is in the locking state, the controller prohibits actuator driving, thereby preventing excessive load generation before it occurs. This preliminary check and conditional prohibition resolves the contradiction by ensuring the actuator is only driven when the locking mechanism is in the unlocking state.
2Strength
If the actuator is prohibited from driving when the locking mechanism is locked, then excessive load is avoided, but the operation member cannot be driven
Solution Approach 1:
The controller receives feedback from the locking mechanism state (locking or unlocking) and adjusts the actuator driving accordingly. When the locking mechanism is in the unlocking state, the controller permits actuator driving; when in the locking state, it prohibits driving. This feedback-based control resolves the contradiction by dynamically adapting the actuator operation to the current locking state, ensuring both load avoidance and operational capability.

AI summary
The optical driver apparatus is detachably attachable to an optical apparatus. The optical apparatus includes a lens operation member operable manually, and a locking mechanism switchable between a locking state of restraining motion of the lens operation member and an unlocking state of releasing the restraint. The optical driver apparatus includes a driver operation member, an actuator configured to move the lens operation member, and a controller configured to control the actuator. The controller is configured to drive the actuator in response to an operation of the driver operation member when the locking mechanism is in the unlocking state and to control the actuator, when the locking mechanism is in the locking state, so as to provide one of a state of not driving the actuator in response to the operation of the driver operation member and a state of performing a warning operation.
