Electronic Device Time Zone Setting with Unified Display Mode
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic timepieces require complex user operations to switch between timekeeping and navigation modes for setting time zones, involving multiple steps and mode changes, which complicates the process of setting the correct time zone based on current location.
Innovation Solution
An electronic device with a receiver for satellite signals, a display, and a control method that allows users to set time zones with simplified operations by displaying set time zone data and initiating navigation or timekeeping modes with a single operation, eliminating the need for additional input device interactions to end time zone display modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the electronic timepiece operates in time zone setting function mode, then the user can select and set time zone data, but the user must perform multiple operations to switch between time zone setting mode and normal time display mode, increasing operational complexity
Solution Approach 1:
The patent combines the time zone setting function with the normal time display function into a single integrated mode. The same display shows both time zone data and navigation mode reception status, eliminating the need to switch between separate modes. This merging of functions allows users to set time zones and check reception status without mode transitions, directly resolving the operational complexity issue.
Solution Approach 2:
The display is designed to serve multiple functions simultaneously: it displays time zone data, navigation mode reception status, and normal time information all in the same mode. This multi-functionality eliminates the need for separate dedicated displays for each function, allowing users to access all information without switching modes and reducing operational steps.
2Reliability
If the electronic timepiece requires switching between different modes for time zone setting and normal time display, then each function can be dedicated to its own mode, but the user must perform additional operations to switch modes, increasing the number of steps required
Solution Approach 1:
The patent merges time zone setting operations and normal time display operations into a single unified mode. The display simultaneously presents time zone data, reception status indicators, and time information without requiring mode transitions. This eliminates the time loss associated with switching between dedicated modes while maintaining functional clarity through distinct visual indicators for each function.
3Loss of information
If the display shows time zone data in a dedicated time zone display mode, then the time zone information is clearly presented, but the user must perform additional operations to end the time zone display mode and return to normal mode
Solution Approach 1:
The patent integrates time zone data display with normal time display in the same mode. The display shows time zone information, reception status, and time data simultaneously without requiring a dedicated display mode. This eliminates the need to enter and exit separate display modes while keeping all information clearly visible through structured presentation on the same display screen.

AI summary
An electronic device has a reception device; a display device; an input device; a display controller that controls the display device to display the set time zone data when a first operation of the input device instructing displaying time zone data is detected; a positioning driver that operates the reception device to run a reception process and acquire positioning information when a second operation of the input device instructing starting reception in the navigation mode is detected while time zone data is displayed on the display device; and a time zone setter that sets time zone data based on the acquired positioning information.
