Camera Rotary Member Actuator Integration for Assembly Tolerance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic devices with camera lenses face assembly tolerance issues and reduced driving transmission efficiency due to misalignment between rotary members and actuators, leading to suboptimal image stabilization during photography.
Innovation Solution
The electronic device incorporates a camera system with a lens barrel supported by a first rotary member and a second rotary member, both connected to actuators that rotate in perpendicular directions, ensuring continuous contact and minimizing assembly tolerance through a preliminary pressure applying member to maintain efficient force transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a separately provided support member is used to support the rotary member and actuator, then the assembly structure is simplified, but assembly tolerance occurs between the rotary member and actuator
Solution Approach 1:
The support member and actuator are integrated into a single unified structure. The actuator is directly mounted on the rotary member's support structure, eliminating the separate support member and thereby removing the interface that caused assembly tolerance. This merging of components ensures precise alignment while maintaining structural simplicity.
2Reliability
If a preliminary pressure applying part is used to allow continuous contact between the actuator and rotary member, then contact continuity is improved, but the pressing direction becomes non-perpendicular to the contact surface
Solution Approach 1:
Instead of applying preliminary pressure from an external support member, the actuator itself is designed with an integrated support structure that inherently maintains the correct perpendicular pressing direction. The actuator's mounting structure is configured so that the pressing force is naturally applied perpendicular to the contact surface, eliminating the need for separate preliminary pressure applying parts and their associated alignment problems.
3Reliability
If a preliminary pressure applying part is used to maintain continuous contact, then contact reliability is improved, but driving transmission efficiency is reduced due to misalignment
Solution Approach 1:
The actuator and its support structure are merged into a single integrated component. This integration ensures that the actuator is precisely positioned and oriented, maintaining continuous contact with the rotary member while applying force in the optimal perpendicular direction. This eliminates the misalignment that would otherwise reduce driving transmission efficiency, while still ensuring reliable continuous contact through the integrated design.

AI summary
An electronic device is provided which includes a housing, a display, a camera, a memory, and a processor. The camera includes a lens barrel, a first rotary member including a first rotary shaft and a first contact part, a second rotary member including a second rotary shaft and a second contact part, a frame, and a control circuit. The first rotary member rotates about the first rotary shaft in a first direction by driving a first actuator, one end of which is coupled to the first rotary shaft and an opposite end of which contacts the first contact part, and the second rotary member rotates about the second rotary shaft in a second direction that is substantially perpendicular to the first direction by driving a second actuator, one end of which is coupled to the second rotary shaft and an opposite end of which contacts the second contact part.
