Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the vibration unit is integrated into the clock host, then the vibration signal can be directly transmitted, but the clock host volume becomes large and inconvenient to carry
Solution Approach 1:
The system is divided into two independent parts: the clock host and the vibration unit. The vibration unit is separated from the clock host and can be independently placed near the user, while the clock host maintains a compact size. This segmentation resolves the contradiction by allowing reliable vibration transmission through wireless communication while keeping the clock host portable.
Solution Approach 2:
Wireless communication (RF signals) acts as an intermediary between the clock host and the vibration unit. Instead of direct physical integration or cable connection, the wireless intermediary enables signal transmission without requiring the vibration unit to be physically integrated into the clock host, thus maintaining compact size while ensuring reliable transmission.
2Ease of operation
If the vibration unit is connected through a cable, then the vibration unit can be placed closer to the user, but the cable is prone to entanglement and damage
Solution Approach 1:
The mechanical cable connection is replaced with a wireless communication system. The vibration control signals are transmitted via RF signals instead of physical cables, eliminating cable entanglement and damage issues while maintaining placement flexibility. The vibration unit can be freely positioned without being constrained by cable length or entanglement.
3Reliability
If the RF receiving module operates continuously, then signal reception is reliable, but power consumption increases
Solution Approach 1:
The RF receiving module operates in periodic wake-up cycles rather than continuously. It periodically wakes up to receive RF signals from the clock host and then returns to sleep mode. This periodic operation maintains signal reception reliability during alarm events while significantly reducing average power consumption during normal operation.
4Adaptability or versatility
If the vibration unit is placed far from the clock host, then user proximity is improved, but cable length limits the distance
Solution Approach 1:
The physical cable connection is replaced with wireless RF communication, eliminating the length constraint imposed by cables. The vibration unit can be placed at any distance within the wireless signal range, providing greater adaptability and versatility in placement options without being limited by cable length.

AI summary
A control method for a wireless RF clock oscillator is provided, which includes a clock host and an independently set vibration unit. The clock host and the vibration unit communicate through an RF signal. The wireless communication between the clock host and the vibration unit avoids a risk of cable entanglement, pulling and damage. Besides that, a mechanism is continuously sent a control signal for a pre-set time. When the clock host sends alarm start or stop signal, an RF transmitting module will send a corresponding signal in a loop for the preset time and then stop it, instead of sending it one time, in coordination with a standby mode of the vibration unit. This ensures that the vibration unit can accurately start to vibrate when the alarm starts, and stop vibrating in a timely manner when the alarm ends, ensuring the reliability of the reminder function.
