Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing assembly of depth elements, cameras, and projectors in electronic devices faces challenges in precise mounting, leading to inefficiencies and reduced performance due to scattered components and large errors in distance measurements, affecting shooting performance and face recognition reliability.
Innovation Solution
An electronic assembly is designed with a bracket that mounts a depth element, a first camera, a projector, and a second camera, where the second camera is positioned opposite to the first camera, and a third camera is adjacent, improving mounting efficiency and reducing optical crosstalk by fixing the components at precise distances using specific protrusions and grooves, and a sliding base mechanism for flexible deployment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple imaging components (depth element, cameras, projector) are scattered and mounted separately in the electronic device, then the device can accommodate these components, but the mounting efficiency is low and assembly errors are large
Solution Approach 1:
The patent combines multiple imaging components (depth element, first camera, projector, second camera) into a single integrated assembly. This merging approach allows all components to be pre-positioned and pre-aligned together as one unit, dramatically improving mounting efficiency when the entire assembly is installed into the electronic device housing, while also ensuring precise relative positioning between components through the unified assembly structure.
Solution Approach 2:
The patent segments the imaging system into a separate modular assembly that can be independently manufactured and tested before final installation. This segmentation allows for specialized precision manufacturing of the assembly itself, while simplifying the main device assembly process. The modular assembly includes mounting protrusions and receiving grooves that enable precise positioning when integrated into the housing.
2Measurement precision
If imaging components are mounted without precise positioning structures, then the assembly process is simple, but the distance measurement accuracy and image overlap reliability are poor
Solution Approach 1:
The patent introduces a bracket as an intermediary component that provides precise positioning structures (mounting protrusions and receiving grooves) between the imaging components and the housing. This intermediary element enables accurate distance measurement and image overlap by ensuring fixed geometric relationships between components, while keeping the overall assembly process manageable through standardized interfaces.
Solution Approach 2:
The patent uses fixed geometric parameters defined by the mounting protrusions and receiving grooves to control the relative positions of imaging components. By establishing predetermined distance parameters and angular relationships through these positioning structures, the system ensures accurate depth measurement and image overlap without requiring complex real-time adjustment mechanisms.
3Volume of moving object
If imaging components are positioned too close together, then the device form factor is compact, but optical crosstalk occurs between components
Solution Approach 1:
The patent applies different spatial arrangement strategies to different components within the assembly based on their optical characteristics. The bracket positions each imaging component at optimized locations that maintain compact overall dimensions while ensuring adequate optical separation where needed. This local optimization prevents optical crosstalk between the projector and cameras while keeping the device form factor compact.
4Adaptability or versatility
If multiple cameras are arranged in different directions, then the shooting coverage is comprehensive, but the assembly alignment precision becomes more difficult to maintain
Solution Approach 1:
The patent merges multiple cameras (first camera and second camera with different imaging directions) into a single integrated assembly with the depth element and projector. This unified structure pre-establishes the precise angular relationships and positioning between cameras pointing in different directions, ensuring comprehensive shooting coverage while maintaining alignment precision through the rigid assembly framework rather than separate mounted components.
