Solution Overview

Problem

Existing TV remote control systems lack the ability to provide tailored TV programs to different users based on their individual preferences and suitability, particularly in preventing minors from accessing inappropriate content.

Innovation Solution

A remote control with an optical sensor that obtains heart rate feature information from users and matches it against a stored library to send specific playing instructions to the TV, ensuring that programs corresponding to the user's identifier are played, and includes features for authentication and priority comparison between users.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If TV programs are made available for different users, then user satisfaction and program suitability are improved, but system complexity increases due to multiple user profiles and authentication mechanisms

Engineering Contradiction:

Improveprogram suitability for different usersVSAvoidsystem complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent replaces traditional mechanical authentication methods (remote control codes, TV password entry) with a biometric authentication system using optical sensors to detect heart rate patterns. This substitution simplifies the user interaction while maintaining security, as users only need to place their finger on the sensor without needing to remember codes or passwords. The biometric data is processed automatically to identify users and provide personalized program recommendations.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system enables self-service authentication where users automatically identify themselves through their unique heart rate patterns detected by the optical sensor. The TV system autonomously matches the detected biometric data against stored profiles and grants access without requiring manual intervention for authentication, thereby reducing operational complexity while improving adaptability to different users.

Inventive Principle:

Principle #25Self-service

2Measurement precision

If biometric authentication is added to the remote control, then user identification accuracy is improved, but device complexity and manufacturing difficulty increase

Engineering Contradiction:

Improveuser identification accuracyVSAvoidmanufacturing difficulty

Core Design Contradiction:

Measurement precisionVSEase of manufacture

Solution Approach 1:

The patent integrates multiple functions into the remote control device, combining the optical sensor for biometric authentication with existing remote control functionalities. The optical sensor serves dual purposes: it acts as both a proximity sensor and a heart rate detector, eliminating the need for separate biometric hardware and reducing manufacturing complexity. This multi-functional approach allows the same component to perform multiple tasks, thereby improving user identification accuracy without proportionally increasing manufacturing difficulty.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Adaptability or versatility

If heart rate detection is implemented in the remote control, then user authentication capability is improved, but device complexity and power consumption increase

Engineering Contradiction:

Improveuser authentication capabilityVSAvoidpower consumption

Core Design Contradiction:

Adaptability or versatilityVSUse of energy by moving object

Solution Approach 1:

The heart rate detection function is activated periodically or on-demand rather than continuously. The optical sensor operates intermittently, triggering authentication only when needed (e.g., when the user attempts to access the TV or change channels). This periodic operation significantly reduces power consumption compared to continuous monitoring, while still maintaining effective user authentication capability whenever required.

Inventive Principle:

Principle #19Periodic action

AI summary

The present disclosure provides a TV program playing method, a remote control and a TV, and the method comprises: obtaining, by the remote control, a first unlock instruction triggered by a first user when a TV system is in standby state; obtaining, by the remote control, a first heart rate feature information of the first user via the optical sensor according to the first unlock instruction; sending, by the remote control, a first playing instruction carrying an identifier of the first user to the TV when a difference between the first heart rate feature information and a second heart rate feature information in a feature library is less than a threshold so that the TV plays a program in a program list corresponding to the identifier of the first user, wherein the feature library pre-stores corresponding relationship between identifiers and heart rate feature information of users.
