Device Identifying Apparatus for Unknown Peripheral Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile terminals struggle to identify and control adjacent devices from different manufacturers or unknown devices due to the lack of pre-existing operation codes and identification information.
Innovation Solution
A device identifying apparatus that includes a memory for storing power and operation codes, a communication unit for transmitting these codes, and a sensing unit to determine if the target device is turned on or driven, allowing the mobile terminal to identify and control the device even if it doesn't have pre-stored information about the target device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the mobile terminal includes pre-stored operation codes and identification information for target devices, then the reliability of remote control function is improved, but the adaptability to unknown devices from different manufacturers deteriorates
Solution Approach 1:
The device identifying apparatus pre-stores multiple power codes corresponding to different device types in its memory. Before actual remote control operation, the apparatus proactively tests these pre-stored power codes by transmitting them to the target device to determine device type and compatibility, enabling the mobile terminal to adapt to unknown devices without requiring pre-installed operation codes for every possible device
Solution Approach 2:
The device identifying apparatus acts as an intermediary between the mobile terminal and the target device. It receives requests from the mobile terminal, autonomously tests power codes to identify the target device type, and then provides the appropriate operation codes back to the mobile terminal. This intermediary mechanism resolves the contradiction by separating the device identification function from the mobile terminal, allowing the terminal to control both known and unknown devices through a unified interface
2Adaptability or versatility
If the mobile terminal tests multiple power codes to identify unknown devices, then the adaptability to various devices is improved, but the time required for device identification increases
Solution Approach 1:
Power codes for multiple device types are pre-stored in the device identifying apparatus memory before runtime. When device identification is needed, the apparatus sequentially transmits these pre-prepared power codes to the target device and detects the responses to determine device type, avoiding the need to generate or search for codes during actual operation
Solution Approach 2:
The apparatus employs periodic sequential transmission of power codes corresponding to different device types. Instead of continuous or random testing, it systematically transmits power codes in a predetermined sequence, allowing efficient identification through periodic detection of device responses within a time window for each transmitted code
3Adaptability or versatility
If the device identifying apparatus stores comprehensive operation codes for multiple device types, then the versatility of remote control is improved, but the memory requirements and device complexity increase
Solution Approach 1:
The system separates the operation code storage function from the mobile terminal and places it in the device identifying apparatus. The apparatus stores power codes corresponding to different device types in its memory, while the mobile terminal only needs to store minimal identification information. This segmentation reduces the memory burden on the mobile terminal while maintaining comprehensive remote control capability through the apparatus
Solution Approach 2:
The device identifying apparatus is designed with multi-functionality: it stores power codes for multiple device types, autonomously identifies target devices by testing these codes, and provides appropriate operation codes to the mobile terminal. This universal apparatus serves multiple purposes (storage, identification, code provision) that would otherwise require separate components, reducing overall system complexity
