Electronic Timepiece Version Display for Local Time Update Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic timepieces lack an efficient method to confirm whether stored local time information is up-to-date, requiring manual connection to a maintenance device to verify updates, which complicates determining if the information needs updating.
Innovation Solution
Incorporating a storage unit for local time information and version information, along with a display control unit to show version information, allowing users or technicians to easily check if the local time information is current, and utilizing satellite or standard time signals to acquire and display accurate time, ensuring timely updates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If local time information is stored in the electronic timepiece for positioning and time zone calculation, then the timepiece can display accurate local time at different locations, but the user cannot easily confirm whether the stored local time information is up-to-date
Solution Approach 1:
The patent introduces version information as an intermediary element that mediates between the stored local time information and the user's need to verify its currency. The version information acts as a simple indicator that can be easily checked without requiring complex verification processes or connection to maintenance devices, thus resolving the contradiction between maintaining accurate time display and enabling easy verification of information currency.
2Reliability
If the electronic timepiece connects to a maintenance device to check local time information content, then the user can verify if updates are needed, but the process becomes complex and inconvenient
Solution Approach 1:
The patent extracts the version verification function from the complex maintenance device connection process and implements it independently within the timepiece itself through the version information storage and display mechanism. This allows users to verify information currency without needing to connect to external maintenance devices, thereby reducing device complexity while maintaining reliability of verification.
3Ease of operation
If version information is stored and displayed to indicate local time information updates, then users can easily determine if updates are needed, but additional storage and display control functionality is required
Solution Approach 1:
The patent implements multi-functionality by using the existing display unit of the electronic timepiece to serve dual purposes: displaying both the time information and the version information. The storage unit and display control unit are integrated into the existing system architecture, allowing the same hardware components to handle multiple functions without significantly increasing overall device complexity, thus achieving ease of version checking with minimal added complexity.

AI summary
An electronic timepiece has a storage unit (flash ROM) that stores local time information related to positioning information and time difference information, and version information of the local time information; a version display unit (display device) capable of displaying the version information; and a display control unit that displays the version information on the version display unit.
