Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices face challenges in ensuring high security against unauthorized use and operation errors, particularly in scenarios requiring stringent authentication, such as unlocking or accessing confidential data.
Innovation Solution
An electronic device equipped with a detection portion to obtain fingerprint and positional data, a memory portion to store registered biometric data, and a control portion to compare and authenticate these data, enhancing security by requiring precise matching of both fingerprint and positional inputs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If fingerprint authentication is implemented, then security is improved, but device complexity increases
Solution Approach 1:
The patent combines the fingerprint sensor with the display panel into an integrated structure, where the sensor is embedded within the display layers. This merging approach enables authentication functionality without adding separate authentication hardware, thus improving security while minimizing increases in device complexity.
Solution Approach 2:
The display panel serves multiple functions: it acts as both the visual display interface and the fingerprint sensing interface. By making the display panel multi-functional, the patent eliminates the need for separate authentication components, resolving the contradiction between enhanced security and device complexity.
2Reliability
If multiple authentication parameters are required, then security is improved, but ease of operation deteriorates
Solution Approach 1:
The patent merges fingerprint recognition with positional information verification into a single integrated authentication process. Both parameters are collected simultaneously through the same display interface, and the system validates them together in one operation, maintaining ease of use while enhancing security through multi-parameter verification.
3Device complexity
If fingerprint sensor is integrated into display portion, then device complexity is reduced, but manufacturing precision requirements increase
Solution Approach 1:
The patent implements a nested structure where the fingerprint sensor is embedded within the display panel layers. The sensor is positioned between specific functional layers of the display, creating a compact integrated assembly. This nesting approach reduces overall device complexity while establishing clear manufacturing guidelines for layer integration and alignment.
