Conventional electronic timepieces face inefficiencies in obtaining date and time information due to complex operation processes and high power consumption when selecting between external device communication and satellite radio wave reception, particularly when location information is also sought.
Innovation Solution
An electronic timepiece with a processor, receiver, and communicator that selects between obtaining date and time information from an external device via Bluetooth or satellite radio waves based on user input, optimizing the operation by skipping unnecessary steps and reducing power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the electronic timepiece provides multiple operation selections for obtaining date and time information (including difficult-to-obtain configurations), then the adaptability is improved, but the operation complexity increases and unnecessary operations are required
Solution Approach 1:
The electronic timepiece automatically determines the appropriate information obtaining operation based on stored setting information, without requiring the user to manually select from multiple operation types. The device serves itself by autonomously selecting whether to perform a first information obtaining operation (e.g., satellite radio wave reception) or a second information obtaining operation (e.g., external device communication) based on pre-stored settings, thereby eliminating unnecessary user operations while maintaining adaptability
Solution Approach 2:
The setting information regarding which information obtaining operation to perform is stored in advance in the electronic timepiece. This preliminary configuration allows the device to automatically execute the appropriate operation without requiring the user to make selections at the moment of need, thus simplifying the operation process while preserving the ability to handle multiple scenarios
2Adaptability or versatility
If the electronic timepiece includes operation selections for obtaining location information along with date and time, then the functionality is improved, but the operation process becomes more complex and time-consuming
Solution Approach 1:
The electronic timepiece automatically selects and executes the appropriate information obtaining operation based on pre-stored setting information, eliminating the need for users to manually choose between different operation types including location information retrieval. The device autonomously determines whether to perform satellite-based or external device-based information obtaining, thereby reducing operation time while maintaining full functionality
Solution Approach 2:
The electronic timepiece is designed to handle multiple functions (date and time obtaining, location information obtaining) through a unified automatic selection mechanism. By storing setting information that covers various scenarios in advance, the device can universally handle different information obtaining needs without requiring separate manual selection processes for each function
3Adaptability or versatility
If the electronic timepiece allows selection between satellite radio wave reception and external device communication, then the adaptability is improved, but the device complexity increases
Solution Approach 1:
The electronic timepiece automatically manages the complexity of multiple communication methods by autonomously selecting between satellite radio wave reception and external device communication based on pre-stored setting information. The device handles the complexity internally without requiring the user to understand or configure the multiple communication options, thus maintaining adaptability while presenting a simple interface

AI summary
An electronic timepiece, including: a receiver which receives broadcast radio waves including time information; a communicator which carries out wireless communication by establishing communication connection with an external device which is set; a processor; and an operation receiving unit which receives an input operation via an operating member, wherein in a case where a predetermined input operation corresponding to a command for obtaining information regarding a present time is received via a predetermined operating member, the processor selects a first information obtaining operation by which the information is obtained from the external device which is set via the communicator or a second information obtaining operation by which the information is obtained based on the broadcast radio waves received by the receiver according to whether a setting regarding the external device exists.
