Solution Overview
Problem
Existing remote control systems for household appliances require users to actively switch between devices and memorize button correspondences, making them inconvenient and less user-friendly, especially when multiple devices are present.
Innovation Solution
A remote control system that uses a rotation vector sensor, ultra-wideband module, and touch display to intuitively identify and control targeted electronic devices by calculating rotation vector and position data, displaying a control interface specific to the device, and transmitting infrared signals for function control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If universal remote controls or learning remote controls are used to control multiple household appliances, then the remote control can switch between different devices, but the user still has to actively press buttons to switch between remote controls and memorize button correspondences
Solution Approach 1:
The remote control device automatically identifies the target electronic device by detecting rotation vector data and position data, and automatically switches to display the corresponding control interface without requiring user intervention to manually select devices or memorize button functions
Solution Approach 2:
The system uses strong sensing capabilities (rotation vector sensor and ultra-wideband module) to rapidly and accurately identify the target device, accelerating the device switching process and eliminating the need for manual device selection
2Device complexity
If fixed button positions and texts are used on the remote control, then the remote control structure is simple, but the user is required to memorize the correspondence between buttons and functions
Solution Approach 1:
The control interface is dynamically generated and displayed on the touch display module based on the detected target electronic device, allowing button positions, texts, and layouts to change automatically according to the controlled device rather than using fixed button arrangements
Solution Approach 2:
The system transitions from traditional fixed physical button layouts to a flexible digital touch display interface, adding the dimension of software-based interface customization that adapts to different electronic devices without changing the physical remote control structure
3Adaptability or versatility
If multiple remote control devices are present in the household, then each household appliance can be controlled, but the user has to find the corresponding remote control device to control a specific household appliance
Solution Approach 1:
The remote control device is designed with universal functionality to control multiple types of electronic devices through automatic identification, eliminating the need for multiple separate remote controls while maintaining the ability to control various household appliances
Solution Approach 2:
The system uses sensors (rotation vector sensor and ultra-wideband module) to continuously detect the user's orientation and position relative to electronic devices, providing real-time feedback to automatically determine and switch to the appropriate control interface
