Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If electronic components are used for timekeeping, then the alarm clock can display time digitally and electronically, but the time accuracy deteriorates due to component errors and temperature changes
Solution Approach 1:
The patent introduces a wireless communication module as an intermediary between the alarm clock and external time sources (smartphones, computers, or network time servers). This mediator receives accurate time data from external devices and transfers it to the clock module, enabling the alarm clock to synchronize with standard time sources and overcome the inherent inaccuracies of electronic components.
2Ease of operation
If manual time adjustment is implemented, then the alarm clock can be set to specific times, but the time accuracy deteriorates due to user errors and disruptions
Solution Approach 1:
The patent implements automatic time synchronization functionality where the alarm clock autonomously obtains time information from external devices through wireless communication. The system automatically calibrates the clock module without requiring user intervention, eliminating manual adjustment errors and ensuring continuous time accuracy. Users simply need to enable the synchronization feature, and the system handles time calibration automatically.
3Measurement precision
If wireless communication modules are added for automatic time calibration, then the time accuracy improves through automatic synchronization, but the device complexity increases
Solution Approach 1:
The patent designs the wireless communication module to support multiple communication protocols (WiFi, Bluetooth, infrared, ZigBee, NFC) and multiple time sources (smartphones, computers, network servers). This multi-functional approach allows the same hardware module to serve various purposes and work with different external devices, reducing the need for separate dedicated components for each function and thereby limiting the increase in overall device complexity.
