Optical Device Moving Groups Collision Avoidance Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In miniaturized image capturing devices, multiple moving groups within a zoom lens system often interfere with each other during movements due to shared moving regions, leading to potential collisions.
Innovation Solution
An optical device with at least two moving groups that share driving regions, utilizing a control unit and actuators to independently move these groups within an integrated coordinate system, ensuring their position coordinates do not coincide, thereby preventing collisions.

1Volume of moving object
If multiple moving groups share driving regions to miniaturize the optical device, then the device size is reduced, but the risk of collision between moving groups increases
Solution Approach 1:
The control unit continuously monitors the positions of multiple moving groups through actuators and adjusts their movements in real-time. By implementing feedback control, the system detects when moving groups approach collision zones and automatically modifies their trajectories to prevent interference, thereby enabling safe sharing of driving regions in a miniaturized device.
Solution Approach 2:
The patent makes the moving groups dynamically controllable by the control unit, which independently adjusts their positions and speeds based on real-time conditions. This dynamic control allows the system to optimize space utilization by having groups share driving regions at different times or under different conditions, while maintaining collision avoidance through active position coordination.
2Device complexity
If multiple moving groups operate independently in shared regions, then the device structure is simplified, but the complexity of controlling their positions increases
Solution Approach 1:
The control unit serves multiple functions simultaneously: it controls the positions of all moving groups, prevents collisions, coordinates actuators, and manages the integrated coordinate system. This universal control approach simplifies the overall device structure by using a single control unit for all operations, while the control unit's sophisticated algorithms handle the complexity of coordinating multiple groups in shared regions.
