Solution Overview
Problem
The existing chip-based anti-shaking mechanism in camera apparatuses occupies large space, hindering further development towards weight reduction and miniaturization due to the use of flexible printed circuits for connection and conduction.
Innovation Solution
A camera apparatus design incorporating a substrate movably connected to a base via an anti-shaking elastic member, with a photosensitive chip and second driving member, allowing the substrate to move relative to the base for shake prevention, reducing the size of the anti-shaking mechanism and improving integration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a camera module is integrated into a smartphone, then photographing function is added, but device complexity increases
Solution Approach 1:
The flash component is nested within the photographing hole of the camera module. The flash is positioned inside the camera module's photographing hole, utilizing the existing space structure. This nesting approach adds the flash function without requiring additional external space, thereby integrating multiple functions (camera and flash) into a single structural unit and reducing overall device complexity.
Solution Approach 2:
The patent merges the flash component with the camera module by positioning the flash within the photographing hole. This combining of separate components (camera lens and flash) into a single integrated structure reduces the number of separate parts and simplifies the overall device architecture while maintaining both photographing and lighting functions.
2Adaptability or versatility
If flash is disposed outside photographing hole, then flash can be disposed, but it occupies additional space and increases device complexity
Solution Approach 1:
The flash component is nested within the photographing hole of the camera module. The flash is positioned inside the camera module's photographing hole, utilizing the existing space structure. This nesting approach adds the flash function without requiring additional external space, thereby integrating multiple functions (camera and flash) into a single structural unit and reducing overall device complexity.
3Illumination intensity
If light guide component is added to guide light, then lighting uniformity is improved, but device complexity increases
Solution Approach 1:
The photographing hole serves multiple functions: it accommodates both the camera lens for photographing and the flash component for lighting. This multi-functional design allows the flash to be positioned within the existing photographing hole structure, using the hole as both an optical path for the camera and a mounting space for the flash, thereby avoiding the need for separate dedicated spaces and reducing overall device complexity.
Solution Approach 2:
The light guide component acts as an intermediary element that receives light from the flash and distributes it uniformly. By introducing this light guide structure within the photographing hole, the patent achieves improved lighting uniformity while keeping the overall design compact, as the light guide utilizes the existing spatial configuration rather than requiring additional external components.

AI summary
This application discloses a camera apparatus, including: a lens, a mounting frame, a first driving member, an anti-shaking driving mechanism, a second driving member, and a photosensitive chip. The lens penetrates the mounting frame. The first driving member is disposed on the mounting frame. The lens and the photosensitive chip are disposed sequentially in a direction of an optical axis of the lens. The anti-shaking driving mechanism includes a substrate, an anti-shaking elastic member, and a base. The substrate is movably connected to the base through the anti-shaking elastic member. Both the photosensitive chip and the second driving member are disposed on the substrate. Therefore, the first driving member is enabled to drive the substrate through the second driving member, thereby enabling the photosensitive chip to follow the substrate for anti-shaking motion.
