Multi-view Camera Lens Adjustment Device Magnetic Locking Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current multi-lens cameras face cumbersome and inefficient operations during P-direction lens adjustments due to frequent loosening and tightening of fastening screws, which hampers operation efficiency.
Innovation Solution
A lens adjustment device featuring a cylindrical component with rotatable lens brackets that engage through tooth slots and teeth, allowing for tension-fit adjustments, enabling easy rotation of lenses around the cylindrical component for P-direction adjustments without the need for frequent screw operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If fastening screws are used to lock the mounting disc, then the lens can be maintained in the adjusted position, but frequent loosening and tightening operations are required, resulting in cumbersome operation and low operation efficiency
Solution Approach 1:
The patent replaces the traditional mechanical fastening screw system with a magnetic field-based locking mechanism. The mounting disc is equipped with a magnet that attracts and holds the lens bracket in the adjusted position, eliminating the need for repeated screw loosening and tightening operations while maintaining position stability.
Solution Approach 2:
The patent changes the locking mechanism from a mechanical friction-based screw system to a magnetic field-based attraction system. This parameter change in the locking mechanism fundamentally alters the operation mode from manual screw adjustment to magnetic field-based position holding, improving both ease of operation and reliability.
2Reliability
If fastening screws are used to lock the mounting disc, then the lens position can be fixed, but the operation becomes complex and time-consuming
Solution Approach 1:
The patent replaces the time-consuming mechanical screw tightening process with an instantaneous magnetic field-based locking mechanism. The magnet on the mounting disc automatically holds the lens bracket in position, reducing the adjustment time from multiple screw operations to a single positioning action.
Solution Approach 2:
The patent extracts the locking function from the mechanical screw system and implements it separately through a magnetic field mechanism. This separation allows the positioning and locking functions to be achieved independently and more efficiently, reducing the time required for adjustment operations.
3Ease of operation
If a simple rotatable mounting disc is used, then the operation is simple, but the lens cannot be maintained in the adjusted position
Solution Approach 1:
The patent merges two previously separate functions into a single integrated mounting disc: the rotatable adjustment function and the position locking function. The magnetic field mechanism is integrated into the mounting disc itself, allowing the disc to both rotate freely for adjustment and automatically lock the lens bracket in the adjusted position without requiring separate locking components.
