Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing portable electronic devices require precise tracing of a preset handwritten pattern to lock or unlock functions, leading to recognition errors and increased user burden, while simplifying the pattern compromises security.
Innovation Solution
A portable electronic device with a display unit and input detection system that allows users to set or release a locked state through continuous or sequential screen operations, reducing user burden while maintaining security by eliminating the need for precise pattern tracing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a handwritten pattern is used for security locking, then security level is improved, but user burden increases due to recognition errors and need for precise tracing
Solution Approach 1:
The patent changes the parameter of input recognition from precise pattern matching to area-based operation counting. Instead of requiring exact tracing of handwritten patterns, the system counts the number of times a display area is touched or operated within a predetermined time period, transforming the security mechanism from precision-dependent to quantity-dependent.
Solution Approach 2:
The patent replaces the mechanical tracing operation system with an automated detection system that monitors and counts display operations. The input detection unit automatically detects and counts operations on the display unit, eliminating the need for manual pattern tracing and reducing user burden while maintaining security through programmed operation thresholds.
2Ease of operation
If the handwritten pattern is simplified to reduce user burden, then ease of operation is improved, but security level is lowered
Solution Approach 1:
The patent changes the security parameter from pattern complexity to operation frequency. Instead of relying on complex handwritten patterns, the system uses the number of display operations within a time period as the security criterion, allowing simple operations to be secured through quantity rather than complexity.
Solution Approach 2:
The system pre-sets the locked state and the predetermined number of operations required for unlocking. The lock control unit is configured in advance to automatically transition from locked to unlocked state when the predetermined operation count is reached, eliminating the need for users to design complex patterns while maintaining security through pre-programmed thresholds.
3Reliability
If precise pattern tracing is required, then security level is maintained, but recognition errors increase and user burden increases
Solution Approach 1:
The patent changes the measurement parameter from precise pattern matching accuracy to operation count threshold. The input detection unit detects display operations and the lock control unit compares the counted operations against a predetermined threshold, replacing precision-based recognition with quantity-based verification that is more tolerant of user input variations.
Solution Approach 2:
The system uses the user's own repeated operations on the display as the security verification mechanism. The input detection unit automatically counts operations performed by the user, and the lock control unit automatically transitions the state when the threshold is met, making the security system self-verifying without requiring external validation or precise pattern matching.

AI summary
A portable electronic device includes a display unit; an input detection unit that detects an input to the display unit, and a lock control unit that sets or releases a locked state for a part or all of functions of the portable electronic device when a predetermined input is detected by the input detection unit, wherein the predetermined input includes inputs, in which a preset screen operation is continuously performed by a predetermined number of times in an area of the display unit.
