Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile phone front cameras have poor imaging quality, making it difficult to achieve high-quality selfies, and existing selfie solutions like reflective mirrors are affected by cleanliness and observation angle.
Innovation Solution
A mobile phone case with a screen projection display module and receiving module that projects the mobile phone's screen onto a display, allowing the user to take selfies or livestream using the rear camera with clear visibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a reflective mirror is used for selfie display, then the user can take selfies with the rear camera, but the display effect is poor and easily affected by cleanliness and observation angle
Solution Approach 1:
The patent introduces a display screen as an intermediary device between the rear camera and the user's eye. Instead of relying on the mirror's reflective properties, the display screen directly presents the camera feed to the user, eliminating the problems of mirror cleanliness and observation angle while maintaining the convenience of rear-camera selfies.
2Ease of operation
If the front camera is used for selfies, then the operation is simple, but the imaging quality is poor and cannot meet high-quality photography requirements
Solution Approach 1:
The patent inverts the conventional selfie approach by using the rear camera (which has high imaging quality) instead of the front camera. The display screen shows the rear camera's view, allowing users to take high-quality selfies while maintaining operational simplicity, thus solving the contradiction between ease of use and imaging quality.
3Reliability
If a display screen is added to the phone case, then clear shooting interface is achieved, but the device complexity increases
Solution Approach 1:
The patent integrates multiple functions into the phone case: it serves as both a protective case and a selfie assistance device with display functionality. By making the phone case multi-functional, the added display screen does not represent pure complexity addition but rather an extension of the case's utility, combining protection, mounting, and display functions in one integrated solution.
