Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the focusing mechanism and anti-vibration mechanism are integrated, then the device can achieve both focusing and anti-shake functions, but the assembly becomes more difficult due to inherent vibrations and centering adjustment requirements
Solution Approach 1:
The patent divides the integrated focusing and anti-vibration mechanism into separate modules: a focusing mechanism with a first coil and lens holder, and an anti-vibration mechanism with a second coil and movable frame. This segmentation allows each mechanism to be assembled and adjusted independently, eliminating the assembly difficulties caused by combined vibrations and centering requirements while maintaining both functions in a single device.
2Adaptability or versatility
If the focusing mechanism and anti-vibration mechanism are integrated, then both functions are achieved, but the mechanism becomes prone to wear and indentation after drop impact
Solution Approach 1:
By separating the focusing mechanism and anti-vibration mechanism into independent modules with distinct coil assemblies and mounting structures, the patent prevents impact forces from affecting the entire mechanism during drop events. The focusing mechanism remains stationary while only the anti-vibration mechanism absorbs impact, eliminating wear and indentation problems that occur when both mechanisms are integrated and subjected to impact together.
3Ease of manufacture
If the locking mechanism is added to lock the drive frame and movable frame, then assembly is facilitated and impact protection is improved, but the device complexity increases
Solution Approach 1:
The patent replaces complex mechanical locking structures with a magnetic locking mechanism where a magnet on the drive frame interacts with a ferromagnetic material on the movable frame. This electromagnetic approach simplifies the locking mechanism by eliminating mechanical latches, springs, and adjustment components, thereby reducing overall device complexity while providing reliable locking and impact protection.

Function Achieved in This Case
Facilitates assembly by reducing inherent vibrations and prevents wear and indentation during drops, maintaining the anti-shake function.
Implementation Method 1
the magnet attracts the locking yoke, causing the drive frame to press against the base
Implementation Method 2
the magnet drives the drive frame to rotate via the drive coil

AI summary
The present invention relates to an imaging device and a camera. The imaging device includes an autofocus lens module with an optical axis, an imaging module, and an anti-vibration mechanism. The anti-vibration mechanism includes, from an image side to an object side in sequence: a base with a magnet disposed thereon; a drive frame rotatably disposed on the base, a rotation axis of the drive frame being perpendicular to the optical axis, a locking mechanism and a drive coil being disposed on opposite sides of the rotation axis; a movable frame with the imaging module fixedly disposed thereon, the movable frame driving the imaging module to move together relative to the optical axis to achieve anti-shake, and a cooperating mechanism corresponding to the locking mechanism being disposed on the movable frame. Such imaging device and camera can reduce assembly difficulty and avoid wear and indentation caused by drop impact.
