Motor Assembly Latch Mechanism for Stable Flip Camera
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions for full-screen smartphones, such as flip cameras, face challenges in stably folding the camera mechanism, leading to potential detachment during vibrations like those experienced in vehicles.
Innovation Solution
A motor assembly with a drive motor, gear, rotation output shaft, displacement mechanism, and latch is used to drive and lock the function module, ensuring it remains securely within the accommodation space by synchronizing linear motion with the shaft and using a latch to engage and disengage the module.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a flip camera mechanism is used to implement full-screen smartphone, then the screen coverage is improved, but the stability of the folded camera mechanism deteriorates
Solution Approach 1:
The latch mechanism is activated in advance to secure the camera module in its folded position before any external vibrations or movements occur. The motor assembly drives the latch to engage with the camera module proactively, preventing potential detachment rather than reacting after detachment occurs.
Solution Approach 2:
The latch acts as an intermediary component between the motor assembly and the camera module. It transfers and secures the connection, ensuring stable engagement of the camera module in the folded state while allowing controlled movement when needed.
2Adaptability or versatility
If the camera module is made detachable for functionality switching, then the adaptability is improved, but the reliability of preventing accidental detachment deteriorates
Solution Approach 1:
The system dynamically adjusts between two states: a locked state where the latch secures the camera module to prevent accidental detachment, and an unlocked state where the camera module can be moved for functionality switching. The motor assembly controls the transition between these states based on operational requirements.
Solution Approach 2:
The motor assembly receives control signals that trigger the latch mechanism to engage or disengage the camera module. This feedback-controlled system ensures the camera module is securely locked during normal operation but can be released when functionality switching is required, balancing reliability and adaptability.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The motor assembly effectively rotates and locks the function module, preventing accidental detachment due to external forces like vehicle vibrations, ensuring reliable operation and functionality switching between lens modes.
