Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional remote controls require users to actively enter passwords or PIN codes for personalized access, which can be cumbersome, and existing biometric remote controls lack practical implementation details for sensor systems.
Innovation Solution
A remote control that detects and processes biometric data from palmar creases and hand vein structures using a biometric sensor, illuminant, pressure sensor, processor, and communication interface, where the biometric sensor activation is coupled with the pressure sensor, allowing for user authentication without additional actions, using a combination of optical sensors and processing algorithms for secure identification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional remote controls use password or PIN code entry for personalized access, then user identification can be achieved, but the operation becomes cumbersome and time-consuming
Solution Approach 1:
The patent replaces the mechanical interaction of typing passwords or PIN codes with an optical sensing system that automatically captures and processes biometric data from the user's hand, eliminating the need for manual input and significantly reducing authentication time
Solution Approach 2:
The system performs automatic biometric authentication without requiring the user to actively participate in the identification process, as the sensor system automatically detects and processes hand characteristics when the user simply holds the remote control
2Ease of operation
If biometric sensors are integrated into remote controls for automated authentication, then ease of operation improves, but device complexity increases
Solution Approach 1:
The patent divides the authentication system into distinct functional modules: illumination source, optical sensor, pressure sensor, and processing unit, allowing each component to be optimized independently and simplifying the overall system architecture
Solution Approach 2:
The remote control integrates multiple sensor types (optical and pressure sensors) that can detect different biometric features, creating a multi-functional authentication system that can adapt to various identification methods within a single device
3Measurement precision
If optical sensors are used to detect palmar creases and hand vein structures, then identification accuracy improves, but energy consumption increases
Solution Approach 1:
The patent implements periodic activation of the illumination source and optical sensor only when authentication is needed, rather than continuous operation, significantly reducing energy consumption while maintaining detection accuracy when required
Solution Approach 2:
The pressure sensor detects hand contact and triggers the optical sensing system in advance, allowing the illumination and detection to occur only when a user is present and authentication is anticipated, optimizing energy usage
