World Timepiece Dial Segmentation for Multi-Zone Readability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing world timepieces face challenges in providing clear and immediate reading of multiple time zones due to visual confusion caused by excessive information on the dial, leading to potential errors in time calculation.
Innovation Solution
A world timepiece dial design featuring a first minute ring, a second hour ring, and a third ring with geographical site markings, allowing simultaneous reading of time zones using a minimal number of digits and large characters, with the third ring's markings aligned for instant time determination across multiple zones.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the dial includes an additional outer ring with names of places for each time zone, then simultaneous determination of time for each time zone is enabled, but the dial carries a large amount of information causing visual confusion and requiring very small characters
Solution Approach 1:
The dial is segmented into three distinct concentric rings, each serving a specific function: the first ring displays hour markers, the second ring displays minute markers, and the third ring displays geographical site names. This segmentation allows each ring to be optimized for its specific purpose, reducing visual confusion while maintaining multi-time zone capability
Solution Approach 2:
The patent transitions from a traditional two-dimensional dial layout to a three-dimensional concentric ring structure. By utilizing the radial dimension, the design can accommodate multiple rings with different information densities, allowing clear display of time and geographical information without crowding
2Adaptability or versatility
If the hour ring is divided into 24 sectors with reference numbers for each time zone, then instant reading of time for multiple time zones is possible, but the dial requires very small characters preventing easy time reading
Solution Approach 1:
The hour and minute information is segmented onto separate rings (first ring for hours, second ring for minutes), while the third ring provides geographical context. This segmentation allows each ring to use appropriate character sizes for its function, with hour and minute markers being larger and more readable than geographical labels
Solution Approach 2:
Different regions of the dial have different information densities and character size requirements. The first and second rings use larger characters for time indicators, while the third ring uses smaller characters for geographical names. This local differentiation optimizes readability while maintaining compact dial design
3Ease of manufacture
If the user must calculate time for each time zone from the time indicated by the hands, then the calculation is simple, but reading of various time zones is non immediate and susceptible to errors
Solution Approach 1:
The dial pre-arranges time zone information by aligning geographical site names on the third ring with their corresponding time offsets. This preliminary organization allows users to instantly read multiple time zones without performing calculations, as the information is already structured for immediate comprehension
Solution Approach 2:
The third ring with geographical site names acts as an intermediary that bridges the time indication function. By combining geographical references with time offset information, it mediates between the simple hour/minute hands and the need for multi-time zone reading, eliminating calculation requirements

AI summary
A world timepiece dial comprising a first ring (2) for minutes, with a first series of digits marked thereon, a second ring (4) for hours, with a second series of digits marked thereon, a third ring (6) with a plurality of time-zone indicating geographical site markings, such markings being adapted to be angularly aligned with the numbers of the first and second series, for instant and simultaneous reading of the time in the geographical sites. The second ring (4) is divided into twelve angular sectors (8, 8', 8",...) each bearing one digit of the second series marked thereon. The markings of the third ring (6) are arranged over at least two concentric circular areas (9, 10), each marking of one of the areas (9) being radially opposed to one marking of at least another area (10) to define respective pairs (11, 11', 11",...). The geographical sites of each pair (11, 11', 11",...) are selected for the time offset between their respective time zones to be twelve hours. An analog timepiece and a digital timepiece comprising the dial.
