Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
User operations are complex when switching between front-facing and rear-facing cameras on foldable screens in electronic devices, particularly for selfie-taking.
Innovation Solution
An electronic device with a flexible display equipped with motion sensors automatically switches to the rear-facing camera for selfie-taking upon detecting a specific flipping motion, reducing the need for manual user intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual switching between front-facing and rear-facing cameras is used, then camera selection flexibility is maintained, but user operation complexity increases
Solution Approach 1:
The system automatically detects user intent through motion sensing and activates the appropriate camera without requiring manual user intervention. The motion sensor detects when the device is flipped, and the system automatically switches to the rear-facing camera, making the device serve itself rather than requiring complex manual operations.
Solution Approach 2:
The patent replaces manual mechanical switching operations with automated motion detection and recognition systems. Instead of requiring users to manually select camera options through interfaces, the system uses motion sensors and intent recognition algorithms to automatically determine and activate the appropriate camera based on detected user actions.
2Ease of operation
If automatic camera switching based on motion detection is implemented, then user operation complexity is reduced, but device complexity increases
Solution Approach 1:
The motion sensor serves multiple functions: it detects device orientation changes, identifies user intent to switch cameras, and triggers appropriate camera activation. This multi-functional approach reduces the need for separate dedicated components for each function, thereby limiting the increase in device complexity.
Solution Approach 2:
The patent introduces an intent recognition model as an intermediary between motion detection and camera activation. This intermediary layer processes motion data, determines user intent, and translates it into appropriate camera switching actions, creating a modular system that manages complexity through functional decomposition.
3Extent of automation
If motion sensors and intent recognition models are added, then automatic camera switching capability is achieved, but manufacturing complexity increases
Solution Approach 1:
The patent combines the motion sensor, intent recognition model, and camera activation logic into an integrated system module. This merging of functions into a unified approach simplifies the manufacturing process by reducing the number of separate components that need to be assembled and configured, while still achieving high automation capability.
