Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple remote control devices are used for controlling different user devices, then each device can be controlled specifically, but the complexity of operation increases and user convenience deteriorates
Solution Approach 1:
The remote control device is designed to control multiple types of user devices (lighting, multimedia, air control) through a single universal interface. The device can automatically identify and adapt to different target devices using optical signal detection and pattern recognition, eliminating the need for multiple specialized remotes while maintaining reliable device-specific control functionality
Solution Approach 2:
The system enables automatic device identification and selection through optical signal transmission and processing. The remote control automatically detects optical signals from user devices, analyzes signal patterns to identify the target device, and establishes control without requiring manual device selection or user input, making the system self-configuring and user-friendly
2Measurement precision
If device addresses are used for identifying user devices, then precise device selection is possible, but the complexity of operation increases when multiple devices of the same type are present
Solution Approach 1:
The system uses optical signal patterns (analogous to color changes) as unique identifiers for each user device. Each device transmits a distinctive optical signal pattern that the remote control can detect and recognize, replacing complex address-based identification with intuitive optical pattern recognition. This allows precise device identification through visual/optical differentiation rather than memorizing addresses
Solution Approach 2:
The patent replaces manual address input or selection mechanisms with automatic optical signal-based identification. The remote control uses optical sensors to detect and analyze signal patterns transmitted by user devices, automatically matching the pattern to the intended target device. This substitutes complex mechanical or manual selection processes with automated optical recognition, simplifying the device selection process while maintaining precise identification
3Reliability
If optical signals with long duration are used for identification, then signal detection reliability improves, but the response time increases
Solution Approach 1:
The optical identification signal uses periodic modulation with specific patterns (alternating high and low states) that can be quickly recognized. The signal is transmitted in structured bursts with defined patterns rather than continuous long-duration signals, allowing the remote control to rapidly detect and identify the device type through pattern recognition while maintaining reliable detection through the periodic nature of the signal
Solution Approach 2:
The optical identification signal includes a predetermined pattern structure with high and low states that are designed for rapid recognition. The signal pattern is pre-configured with distinctive characteristics (specific durations of high and low states) that enable the remote control to quickly identify the device type without requiring prolonged signal transmission or complex analysis, achieving fast and reliable identification
