Touch Sensitive Processing Apparatus Power Saving Mode Gesture Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for an electronic system that can receive a power-on command via a touch gesture on a touch-sensitive area in a power saving mode and switch to a normal operation mode, which consumes more power, eliminating the need for a dedicated on/off button and enhancing device aesthetics and waterproof capabilities.
Innovation Solution
The system includes a host, a power supply module, and a touch-sensitive processing apparatus with electrode interface components and a processor that detects touch events on a touch panel to determine a power-on command and send a notification to the power supply module to switch from power saving to normal operation mode.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a dedicated on/off button is used to switch between power saving mode and normal operation mode, then the system can reliably receive power-on commands, but the device structure becomes more complex, aesthetic appearance is compromised, and waterproof ability is reduced
Solution Approach 1:
The invention extracts the power-on command reception function from the dedicated mechanical button and relocates it to the touch-sensitive area. The touch-sensitive processing apparatus independently detects touch gestures and generates power-on notifications, separating this function from the mechanical button structure while maintaining reliable command reception.
Solution Approach 2:
The touch-sensitive area is given multiple functions: it serves as both the display interface and the power-on command input interface. By detecting specific touch gestures (such as pressing the power icon displayed on the screen), the same area that displays information also receives control commands, eliminating the need for separate dedicated buttons.
2Reliability
If a dedicated on/off button is used to switch modes, then the system can reliably receive power-on commands, but the device's waterproof ability and casing strength are reduced
Solution Approach 1:
The invention removes the mechanical button component from the device casing, extracting its function to the touch-sensitive area. This eliminates the physical opening or recess needed for the button, thereby improving casing integrity, strength, and waterproof sealing.
Solution Approach 2:
The mechanical button system is replaced with an electronic touch-sensitive system. Instead of physical contact through a mechanical interface, users interact through capacitive or resistive touch sensing, which requires no physical openings in the casing, thus maintaining full sealing and structural integrity.
3Ease of operation
If the touch sensitive processing apparatus receives power in power saving mode to detect touch gestures, then the system can switch to normal operation mode via touch gesture, but the power supply module must maintain power to the touch sensitive processing apparatus during power saving mode
Solution Approach 1:
The power supply system is segmented into two independent parts: the host system that enters power saving mode with minimal or no power, and the touch-sensitive processing apparatus that receives dedicated minimal power to maintain detection capability. This segmentation allows the touch function to remain operational while the main system conserves energy.
Solution Approach 2:
The touch-sensitive processing apparatus maintains a ready state with minimal power during power saving mode, performing preliminary detection of touch gestures. When a touch gesture is detected, it immediately triggers the power-on notification to the host system, avoiding the need for full system power to be maintained continuously.

AI summary
The present invention provides a touch sensitive processing method for switch an electronic system into a normal operation mode upon receiving a touch gesture in a power saving mode. The electronic system includes a host and a power supply module. The host is configured to execute an operating system to control the electronic system in the normal operation mode. The power supply module is configured to supply power to the host in the normal operation mode and to cut power supply to the host in the power saving mode. The touch sensitive processing method includes: detecting multiple touch events via multiple touch sensitive electrodes of a touch panel; determining whether a power-on command is formed by these touch events; and sending a power-on notification to the power supply module for supplying power to the host and switching to the normal operation mode when the power-on command is formed by these touch events.
