Rotatable Display Cyclic Patterns for Electronic Timepiece Readability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic timepieces with rotational members struggle to effectively display various types of information in a way that is easy to recognize and understand, as simple movements of these members do not adequately convey changes in displayed information across multiple functions.
Innovation Solution
An electronic timepiece featuring a first display section with a rotatable part that simultaneously displays multiple contents at predetermined angles, creating a cyclic display pattern, and a processor that selects angular positions to rotate the part, ensuring the display content changes are visually dynamic and user-friendly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If multiple types of information are displayed using simple movements of rotational members to specific destinations, then various functions can be displayed, but the displayed information is too simple to recognize change and lacks visual dynamics
Solution Approach 1:
The patent applies periodic action by making the first rotatable part rotate cyclically through multiple display patterns, where the same display content appears multiple times at different angular positions. This periodic repetition creates visual dynamics that make information changes easily recognizable, while the cyclic nature allows the system to maintain a relatively simple mechanical structure without requiring complex multi-position mechanisms.
2Adaptability or versatility
If a single display content is shown at a time, then the display is simple, but multiple functions cannot be displayed simultaneously
Solution Approach 1:
The patent segments the display content by simultaneously displaying multiple types of information (first through fifth display contents) at different angular positions around the rotatable part. Each segment of the rotation displays a different function, allowing multi-functionality while maintaining clear visual separation. The processor selectively rotates to specific angular positions to display relevant information, making it easy for users to recognize and differentiate between various functions.
3Measurement precision
If rotational members move to specific destinations to display information, then accurate information can be shown, but the movement is too simple to convey change effectively
Solution Approach 1:
The patent adds the temporal dimension of cyclic rotation to the spatial arrangement of display contents. Instead of simply moving to different positions, the rotatable part completes multiple cycles, presenting the same display content at different angular positions across multiple patterns. This dimensional transformation creates rich visual dynamics that effectively convey information changes while maintaining precise angular positioning for accurate display.

AI summary
An electronic timepiece includes a first display section including a first rotatable part and a processor. In the first display section, a predetermined number of display contents being a same display content is simultaneously displayed at predetermined angle intervals in a rotation angle range of the first rotatable part, wherein the predetermined number is two or more. The first display section makes a display pattern that shows change in the display content appear the predetermined number of times cyclically according to rotation of the first rotatable part. When causing the first display section to display a first display content of first display contents included in the display pattern, the processor selects an angular position from angular positions for the first display content in the predetermined number of display patterns, and causes the first rotatable part to rotate to the selected angular position.
