Innovation Solution
Incorporating an illuminance sensor, infrared sensor, and impact sensor into the display apparatus to detect user inputs, allowing the controller to perform operations based on combinations of sensor outputs, eliminating the need for a button-type input device and enabling remote controller signal detection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a button-type input device is provided in the display apparatus, then user input capability is ensured, but manufacturing cost and device complexity increase
Solution Approach 1:
The patent makes existing sensors (illuminance sensor, infrared sensor, impact sensor) perform dual functions: their original functions (brightness detection, remote control reception, collision detection) plus new input device functions. By configuring the controller to recognize sensor output combinations as input commands, the sensors serve multiple purposes, eliminating the need for separate button components and reducing overall device complexity while maintaining user input capability
Solution Approach 2:
The patent merges the input device function with existing sensor components. Instead of having separate buttons and sensors, the controller combines signals from multiple sensors (e.g., illuminance sensor detecting hand coverage plus infrared sensor detecting body heat) to recognize user input intentions. This merging eliminates redundant components and simplifies the device structure while preserving input functionality
