Squeezing Pressure Detection for Mobile Terminal Wake-Up
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Bar type mobile terminals lack intuitive methods to transition from a sleep mode to a wake-up state or activate hot keys, requiring users to press a hold key, which is inconvenient and contradicts design principles of minimizing button usage.
Innovation Solution
Incorporating pressure sensors and proximity sensors to detect squeezing pressure, allowing the mobile terminal to wake up or activate hot keys when the user grips the device, eliminating the need for pressing additional keys.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a hold key is used to wake up the mobile terminal, then the terminal can be awakened from sleep mode, but the user experience deteriorates due to the need to press additional keys and the loss of intuitive state transfer
Solution Approach 1:
The mobile terminal uses its own sensors (pressure sensor and proximity sensor) to detect user interaction and automatically wake up without requiring manual button pressing. The terminal serves itself by interpreting the squeezing action as a wake-up command, eliminating the need for additional control buttons.
Solution Approach 2:
The patent replaces the mechanical button-pressing system with a sensor-based detection system. Instead of using a physical hold key, the terminal uses pressure sensors and proximity sensors to detect the squeezing action and automatically trigger wake-up, substituting mechanical interaction with sensor-based automation.
2Device complexity
If the number of buttons is reduced, then the device design is simplified, but the terminal cannot intuitively transfer its current state to the user
Solution Approach 1:
The squeezing action serves multiple functions: it simultaneously detects both the proximity state (through pressure sensor) and triggers the wake-up action (through proximity sensor). This multi-functional interpretation of a single gesture restores intuitive state transfer without requiring additional buttons.
Solution Approach 2:
The terminal provides immediate feedback to the user by detecting the squeezing action through pressure and proximity sensors and automatically responding with wake-up. This feedback loop restores the intuitive connection between user action and terminal state, eliminating the need for additional buttons.
3Productivity
If a hold key is pressed to wake up the terminal, then the terminal transitions to wake-up state, but the user cannot immediately use hot keys due to the additional pressing required
Solution Approach 1:
The terminal is pre-configured to automatically wake up when it detects a squeezing action through its sensors. This preliminary setup eliminates the need for users to press hold keys before accessing hot keys, allowing immediate hot key usage as soon as the terminal is squeezed awake.
