Dynamic Object Lock Screen for Portable Terminal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional portable terminals have a monotonous operation mechanism for releasing the touch lock function, which can lead to accidental and inconvenient 'pocket dialing', and there is a need for an improved method to control the lock function.
Innovation Solution
An apparatus and method that change the shape or position of objects on a function lock screen in a portable terminal, using a display unit and processors to control the lock function based on user input, with objects having variable areas indicating the extent of change, allowing for user interaction to release or enter the lock mode.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional touch lock function is implemented with fixed operation mechanisms, then the lock function can prevent accidental touch inputs, but the operation mechanism becomes monotonous and user satisfaction decreases
Solution Approach 1:
The patent applies dynamics by making the lock screen objects changeable and adaptable. Instead of fixed operation mechanisms, the system dynamically adjusts object shapes, positions, and combinations based on user interactions. The lock function maintains reliability while improving ease of operation through these dynamic changes, directly resolving the contradiction between consistent lock protection and varied user experience.
Solution Approach 2:
The patent utilizes parameter changes by modifying object parameters (shape, position, size) on the lock screen. The control unit changes these parameters in response to user inputs, creating varied operation mechanisms while maintaining the lock function's effectiveness. This approach allows the system to prevent accidental inputs while providing engaging and diverse interaction patterns.
2Device complexity
If the lock screen uses fixed object shapes and positions, then the implementation is simple, but user satisfaction and engagement decrease
Solution Approach 1:
The system implements dynamic object transformations on the lock screen, where objects can change shape, position, and configuration based on user interactions. The control unit manages these changes without requiring complex hardware modifications, maintaining relatively simple implementation while significantly enhancing user engagement through varied and engaging operation mechanisms.
Solution Approach 2:
The patent introduces dimensional changes by allowing objects to transform in multiple dimensions (shape, position, size) rather than relying on fixed two-dimensional static elements. This adds depth and variety to the lock screen interactions, improving user engagement while the software-based implementation keeps the overall device complexity manageable.
3Ease of manufacture
If conventional touch lock methods are used with pre-set patterns, then the lock function is easy to implement, but the operation mechanism becomes monotonous
Solution Approach 1:
The patent implements a universal lock screen system where objects can serve multiple functions - they can be moved, resized, shaped, combined, and separated. This multi-functionality allows the same basic object framework to support diverse operation mechanisms, maintaining ease of implementation while providing variety in user interactions. The control unit manages these varied operations through a unified software architecture.
Solution Approach 2:
The system transitions from static pre-set patterns to dynamic object manipulations. Objects on the lock screen can be dynamically modified in shape, position, and configuration, creating varied operation mechanisms without requiring multiple separate implementations. This dynamic approach maintains ease of manufacture through software flexibility while significantly improving operation mechanism variety.
