Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing number of electronic components in terminal devices is hindered by the space occupied by both front-facing and rear-facing cameras, making it difficult to integrate more components due to their combined housing space requirements.
Innovation Solution
A photographing module that functions as both a front-facing and rear-facing camera by using a light sensing chip that captures ambient light from different sources through adjustable light capturing holes, eliminating the need for separate cameras and reducing housing space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If both a front-facing camera and a rear-facing camera are equipped in the terminal device, then different photographing requirements are satisfied, but the space occupied in the housing increases
Solution Approach 1:
The light sensing chip is designed to perform multiple functions by capturing light from different directions. Through optical elements and adjustable light capturing holes, the same chip can function as both a front-facing camera for selfies and a rear-facing camera for general photography, eliminating the need for separate camera modules
Solution Approach 2:
The patent combines the front-facing camera and rear-facing camera functions into a single integrated photographing module. The light sensing chip, optical elements, and housing structure are merged into one unit that can capture light from both front and rear directions, reducing the total number of components and space occupation
2Area of stationary object
If the front-facing camera is made retractable to extend out of the housing, then the screen-to-body ratio is increased, but the device complexity and space management become more difficult
Solution Approach 1:
The invention extracts the light capturing function from a traditional retractable camera mechanism and integrates it into a fixed housing structure. By using adjustable light capturing holes and optical elements within a stationary module, the front-facing camera function is achieved without requiring mechanical extension and retraction mechanisms
Solution Approach 2:
The patent introduces dynamic adjustability through adjustable light capturing holes that can change their opening direction or position. This dynamic feature allows the same fixed structure to adapt to different photographing scenarios (front-facing and rear-facing) without mechanical movement of the entire camera module
