Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile phone cameras typically have two separate cameras with independent photosensitive chips, leading to increased cost and size due to redundant components.
Innovation Solution
A camera device design where a single photosensitive chip is shared between two camera assemblies, rotating between them using a driver and transmission component, allowing both cameras to function without the need for duplicate chips.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If two separate cameras with independent photosensitive chips are used, then each camera can function independently, but the cost and size of the device increase due to redundant components
Solution Approach 1:
The patent merges two separate photosensitive chips into a single shared photosensitive chip that can be optically coupled to either the first or second camera assembly through a switching mechanism. This combining approach eliminates redundant components while maintaining the capability to support both cameras, directly resolving the contradiction between reliability and device size.
Solution Approach 2:
The single photosensitive chip is designed to serve multiple functions by being switchably coupled to different camera assemblies. The optical switching mechanism allows the same photosensitive chip to function with either camera, providing multi-functionality that reduces overall device size while preserving camera operation capabilities.
2Reliability
If two separate cameras with independent photosensitive chips are used, then each camera can function independently, but the cost of the device increases
Solution Approach 1:
The patent combines the photosensitive sensing function into a single shared component rather than requiring two separate chips. This merging reduces the total bill of materials cost and manufacturing complexity while maintaining the ability to support both camera assemblies through optical switching.
Solution Approach 2:
The single photosensitive chip provides universal functionality for both camera assemblies, eliminating the need to manufacture and stock two separate expensive components. The optical switching mechanism adds minimal cost compared to the savings from eliminating one entire photosensitive chip assembly.
3Volume of stationary object
If a single photosensitive chip is shared between two camera assemblies, then device size and cost are reduced, but the complexity of switching between cameras is increased
Solution Approach 1:
The patent introduces an optical switching mechanism as an intermediary component that manages the connection between the single photosensitive chip and the two camera assemblies. This intermediary handles the complexity of switching, allowing the photosensitive chip itself to remain a simple, unified component while enabling flexible camera operation through controlled optical routing.

AI summary
A device with two cameras utilizing one photosensitive assembly includes a first camera assembly, a second camera assembly, and the photosensitive assembly. The first camera assembly and the second camera assembly are symmetrically positioned at both sides of the photosensitive assembly. The photosensitive assembly includes a driver and a connected photosensitive chip, the driver can drive the photosensitive chip to rotate, so that a photosensitive surface of the photosensitive chip is rotated between the first camera assembly and the second camera assembly. Therefore, the first camera assembly and the second camera assembly of the camera device are able to share one photosensitive chip, thereby the overall size and cost of the camera device is reduced. The present application also provides a mobile terminal having the camera device.
