Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current human-computer interface technologies, such as those used in touch display panels, are inefficient and lack confidentiality, particularly in emergency situations where users struggle to quickly and secretly send messages or calls, as they require unlocking and manual input, which can be slow and risky.
Innovation Solution
An electronic device with a fingerprint recognition area on the display unit and a sensing unit below it, allowing for simultaneous capture of fingerprint information from at least two fingers, which, when matched with preset data, executes predefined commands, such as sending emergency messages, using a processing unit and optional capacitance and pressure sensing units for enhanced accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If traditional touch display interface is used for emergency communication, then device structure remains simple, but operation speed is slow and confidentiality is compromised due to required unlocking and manual input
Solution Approach 1:
The patent merges the fingerprint sensing function with the display touch function by integrating the sensing unit below the display unit at the fingerprint recognition area. This combination allows the device to use a single integrated component for both display and biometric authentication, eliminating the need for separate unlocking and messaging actions, thereby speeding up emergency communication while maintaining relatively simple device structure.
Solution Approach 2:
The system pre-configures multiple fingerprint information templates corresponding to different operation commands during normal usage. When emergency situation is detected through multi-fingerprint recognition, the pre-configured commands can be executed immediately without requiring manual input or sequential authentication steps, thus achieving rapid emergency response.
2Reliability
If multi-fingerprint recognition is implemented for emergency commands, then operation confidentiality is improved, but fingerprint recognition accuracy requirement increases
Solution Approach 1:
The system incorporates capacitance detection unit and pressure sensing unit that work together with the fingerprint sensing unit to provide multi-parameter feedback. By monitoring capacitance changes and pressure distribution alongside fingerprint patterns, the system can verify multi-fingerprint authenticity more reliably, ensuring high confidentiality while maintaining practical recognition accuracy through multiple verification dimensions.
3Length of stationary object
If sensors are integrated within the display area, then device thickness is reduced, but sensor detection sensitivity may be compromised
Solution Approach 1:
The sensing unit is nested below the display unit, with the fingerprint recognition area positioned at the display surface and the sensing components layered underneath. This nested arrangement allows the sensing functionality to be embedded within the existing display structure, reducing overall device thickness while maintaining adequate detection sensitivity through the layered configuration that preserves sensor-to-fingerprint contact quality.

AI summary
An electronic device and a command execution method for a fingerprint recognition-based electronic device are provided. The electronic device includes a display unit and a sensing unit. A fingerprint recognition area is provided on the display unit. When the captured fingerprint information includes fingerprint information of at least two fingers, it means that the user touches the fingerprint recognition area with multiple fingers, it is likely that an emergency occurs. Then, the fingerprint recognition unit matches the collected fingerprint information with the preset fingerprint information, and if the matching is successful, the processing unit executes a corresponding operation command. Compared with the existing technology, the electronic device of the present disclosure facilitates user operations and makes sending an emergency message more conveniently, efficiently and secretly; on the other hand, the electronic device greatly reduces the overall thickness of mobile devices, making mobile devices thinner and lighter to meet market demand.
