Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional IoT device control methods are inconvenient, requiring users to manually find and control devices through applications or voice commands, which can be difficult due to the complexity of recognizing device capabilities and states.
Innovation Solution
An electronic device with a physical user interface (PUI) that detects external devices, maps its functions to control capabilities, and allows users to control these devices through intuitive physical inputs, providing visual, tactile, and acoustic feedback for easy operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional IoT device control methods are used (applications or voice commands), then device control capability is provided, but user convenience deteriorates due to the need to manually find and control devices
Solution Approach 1:
The electronic device performs preliminary detection of external devices and pre-maps physical input device functions to external device control capabilities before user interaction. This allows the system to be ready for immediate control without requiring users to search for devices or configurations.
Solution Approach 2:
The system automatically detects external devices, identifies their control capabilities, and maps them to physical input device functions without requiring user intervention. The electronic device serves itself by autonomously establishing the control interface.
2Ease of operation
If voice commands are used for IoT device control, then control simplicity is improved, but accuracy deteriorates due to difficulty in recognizing device capabilities and states
Solution Approach 1:
The physical input device serves as an intermediary between the user and the external device control system. It provides tactile feedback and visual confirmation that help users accurately understand device capabilities and current states, bridging the gap between simple voice commands and precise control.
Solution Approach 2:
The system provides visual feedback through displays and tactile feedback through the physical input device when users interact with external device controls. This feedback loop enables users to accurately recognize device capabilities and current states, improving control precision while maintaining simplicity.
3Reliability
If physical input device functions are fixed, then device reliability is improved, but adaptability deteriorates when controlling different external devices
Solution Approach 1:
The function mapping between the physical input device and external device control capabilities is dynamic rather than fixed. The system can adapt the mapping in real-time based on the detected external device type and its control requirements, while the physical input device itself remains stable and reliable.
Solution Approach 2:
The physical input device is designed with multi-functionality, capable of serving both its original functions and external device control functions. Through dynamic function mapping, a single physical input device can adapt to control various types of external devices with different capabilities.

AI summary
An example electronic device may include a display module, a communication module, a physical input device, and a processor. The processor may detect a trigger related to external device control from the electronic device and identify a capability to be controlled by the external device, based on the detection of the trigger. The processor may change a first function configured to cause a designated physical input device of the electronic device to operate, to a second function related to control of the identified capability of the external device and control the capability of the external device on the basis of detection of a user input through the physical input device.
