Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices with flexible displays face inconvenience in activating or deactivating the auto-framing function, requiring manual user input, which is inefficient and cumbersome.
Innovation Solution
The electronic device automatically activates the auto-framing function based on predefined conditions, such as being folded within a specified angle range and detecting an object in the camera's field of view, without the need for user input.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual user input is required to activate or deactivate the auto-framing function, then the device can respond to user intentions, but the ease of operation deteriorates due to the cumbersome manual activation process
Solution Approach 1:
The system automatically activates the auto-framing function by detecting the device's own state (folded angle) without requiring external user input. The sensor detects when the device is folded within a specified angle range and automatically triggers the camera application with auto-framing enabled, allowing the device to serve itself by interpreting its physical state as a user intention.
Solution Approach 2:
The system performs preliminary detection of the device's folded state using the sensor before activating the auto-framing function. By continuously monitoring the folded angle and preparing the camera application in advance when the device enters the specified angle range, the system eliminates the need for manual activation and reduces time loss.
2Ease of operation
If the auto-framing function is activated automatically based on folded state detection, then the ease of operation improves, but the device complexity increases due to additional sensors and control logic
Solution Approach 1:
The sensor that detects the folded state is utilized for multiple purposes: determining the device's operational mode, triggering the camera application, and activating the auto-framing function. This multi-functional use of the sensor and control logic minimizes the addition of new components while achieving automatic activation.
Solution Approach 2:
The control logic for detecting the folded state, determining the operational mode, and activating the auto-framing function is merged into a unified control process. The processor integrates these functions, using the sensor input to directly trigger the camera application with auto-framing enabled, thereby reducing overall system complexity.
3Productivity
If the camera application is automatically executed with auto-framing when folded within a specified angle range, then the productivity improves by eliminating manual steps, but the device complexity increases due to integrated control mechanisms
Solution Approach 1:
The system automatically executes the camera application with auto-framing enabled by detecting the device's folded state, allowing the device to initiate the complete workflow (detection → application execution → function activation) without manual intervention. This self-service approach eliminates multiple manual steps and improves productivity.
Solution Approach 2:
The system performs preliminary detection of the folded state and pre-configures the camera application before execution. By continuously monitoring the folded angle and preparing the application in advance, the system enables rapid automatic execution when the threshold is reached, improving productivity without requiring complex real-time processing during camera operation.
