Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional rear seat entertainment systems require passengers to physically move forward to operate the touch screen on the backrest of the front seat, which is inconvenient.
Innovation Solution
A rear seat entertainment remote controller equipped with a biometric sensor that senses user biometric signals and finger gestures, allowing for remote control of the rear seat monitor without physical touch, using a sensing module with ECG and PPG sensors, and a short-range wireless communication module for Bluetooth communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a touch screen is disposed on the backrest of the front seat, then the rear seat entertainment function is provided, but the rear seat passenger must move upper body forward to operate the screen which reduces ease of operation
Solution Approach 1:
A remote controller is introduced as an intermediary device between the user and the rear seat entertainment system. The remote controller includes a sensing surface with biometric sensors that detect user input, allowing operation of the entertainment system without requiring the user to physically approach or touch the screen on the front seat backrest.
Solution Approach 2:
The patent replaces mechanical touch interaction with biometric sensing technology. Instead of requiring physical contact with the screen, the system uses biometric sensors to detect user presence and input, substituting the mechanical operation mode with a non-contact sensing mechanism.
2Adaptability or versatility
If biometric sensors are added to the remote controller, then healthcare function is provided, but device complexity increases
Solution Approach 1:
The remote controller is designed with multi-functionality, serving both as a control device for the rear seat entertainment system and as a healthcare monitoring device. By integrating biometric sensors into the remote controller, it can perform multiple functions including entertainment control and health monitoring, making the device more versatile without requiring separate devices.
3Measurement precision
If the sensing surface includes multiple sensors, then measurement precision is improved, but manufacturing precision requirements increase
Solution Approach 1:
The sensing surface is divided into multiple sensing regions with different types of biometric sensors (ECG sensors, PPG sensors, impedance sensors). Each sensor type is positioned in specific segments of the sensing surface to detect different biometric parameters. This segmentation allows for specialized measurement capabilities while organizing the complex sensor array into manageable functional zones.

Function Achieved in This Case
Enables passengers to control the rear seat monitor and receive healthcare information such as heart rate, stress analysis, and emotional state without needing to physically interact with the screen, enhancing convenience and accuracy of healthcare measurements.
Implementation Method 1
the biometric sensor may include an electrocardiogram (ECG) sensor
Implementation Method 2
a photoplethysmogram (PPG) sensor
Implementation Method 3
The sensing module may sense the finger gesture based on a change in impedance on the plurality of divided electrodes
