Mobile Terminal Activation Sensing Unit for Energy-Efficient Function Execution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile communication terminals require a user to manually activate functions by turning on the display and navigating through interfaces, which can be inconvenient and limit the ability to perform operations without fully activating the device.
Innovation Solution
A mobile communication terminal equipped with an activation sensing unit that detects a change from an inactive state (display off, communicable) to an active state (display on, communicable) and performs a predetermined operation when this change is detected, allowing functions to be executed without fully activating the display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the display is turned on to operate functions, then the terminal can perform various operations, but the energy consumption increases and the operation becomes more complex
Solution Approach 1:
The patent applies partial action by enabling specific functions to operate without fully activating the display. The sensing unit detects user input (touch, gesture, or button press) and activates only the necessary function temporarily, rather than requiring full display activation. This allows energy-efficient operation for specific tasks while maintaining ease of use.
2Adaptability or versatility
If additional interface or button is added to perform specific function, then the function can be executed, but the device complexity increases
Solution Approach 1:
The patent implements universality by enabling the display and sensing units to serve multiple purposes. The display acts as both a full interface when activated and a touch-sensitive input surface when inactive. The sensing unit detects various input types (touch, gesture, button press) to trigger different functions, allowing one component to fulfill multiple operational roles without adding separate dedicated buttons or interfaces.
Solution Approach 2:
The patent merges the functions of separate components into unified operations. The touch input on the inactive display is combined with button press detection through the same sensing unit. Multiple functions (health sensing, authentication, location transmission) are merged into a single activation mechanism, reducing device complexity while maintaining versatility.
3Use of energy by moving object
If the terminal is kept in inactive state to save energy, then energy consumption decreases, but the ability to perform operations without activation is limited
Solution Approach 1:
The patent applies preliminary action by preparing the sensing unit to detect user input even when the display is inactive. The system maintains readiness to recognize touch, gesture, or button press inputs without requiring full activation. When input is detected, the system immediately activates the appropriate function, bridging the gap between energy-saving inactive state and operational capability.

AI summary
A mobile terminal includes a touch screen display, a camera, a power button and an activation button for turning on the touch screen display. The mobile terminal has a first function and a second function to perform in response to user input and provides user settings for configuring at least one of the first and second functions such that the at least one of the first and second functions is performed along with turning on the touch screen display when pressing of the activation button is detected while the touch screen display is turned off. The mobile terminal is configured to perform the first and second functions depending upon length of pressing of the activation button in addition to turning on the touch screen display.
