Altitude Indicator Radial Numerals Watch Dial
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing watch altimeters with partially numbered scales can lead to misreading of altitude in critical situations due to space limitations on the dial.
Innovation Solution
The watch incorporates an altitude indicator with markers labeled with corresponding numerals or letters on their extension lines, allowing for easy recognition of altitude without obstructing the pointers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If numerals are placed on the dial to label markers, then altitude recognition is improved, but the dial becomes crowded and visibility of other elements deteriorates
Solution Approach 1:
The patent extends numerals along the radial direction from the markers outward toward the dial perimeter, utilizing the radial dimension rather than placing all numerals in the circular dial plane. This allows altitude labels to be displayed without occupying additional dial area, resolving the contradiction between altitude recognition accuracy and dial space availability.
2Measurement precision
If markers are densely packed to show detailed altitude intervals, then measurement precision is improved, but readability of individual markers deteriorates
Solution Approach 1:
By extending numerals radially outward from densely packed markers, the patent allows fine altitude interval markers to remain close together for precision while their corresponding numerals extend outward into less crowded radial space, improving both measurement precision and marker readability simultaneously.
Solution Approach 2:
The numeral labeling system is segmented and distributed along radial extension lines from each marker, rather than grouping all numerals together. This segmentation allows each marker to have its own clearly visible numeral extension, maintaining readability even when markers are densely packed for high precision altitude indication.

AI summary
Provided is a watch including a dial, a first pointer, and a second pointer. A plurality of hour markers and a plurality of markers other than the plurality of hour markers are mounted on the watch. The first pointer points at one of the plurality of hour markers on the dial by rotating around a first rotation axis. The second pointer points at one of the plurality of markers on the dial by rotating around a second rotation axis. Numerals or letters respectively corresponding to the plurality of markers are placed on respective extension lines of the plurality of markers adjacent to one another.
