Rotary Counter Display Spacing Dynamics
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rotary indicator displays face challenges in reducing the window height while maintaining good legibility, as constant character spacing fails to accommodate varying values effectively, leading to either overloading or incomplete character display.
Innovation Solution
A method that varies the spacing between characters in a rotary indicator window, adjusting between a maximum and minimum value based on the number of characters visible, allowing for a smaller window height without compromising legibility by ensuring at least one character remains fully visible.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the window height is reduced to display more data, then the quantity of information displayed increases, but the legibility of characters decreases
Solution Approach 1:
The patent applies dynamics by making the character spacing variable rather than fixed. The spacing between characters automatically adjusts based on the number of characters visible in the window, allowing the display to adapt to different states (single character vs. multiple characters). This dynamic adjustment enables the window height to be reduced while maintaining legibility, as the spacing contracts when multiple characters are visible and expands when a single character is displayed.
Solution Approach 2:
The patent changes the parameter of character spacing from a constant value to a variable parameter that depends on the display state. By making the spacing parameter dynamic based on the number of visible characters, the system can reduce window height while preserving legibility. The spacing parameter is adjusted according to whether one or multiple characters are visible, optimizing the display for each state.
2Device complexity
If constant spacing between characters is used, then the display structure is simple, but the window height cannot be reduced without compromising character visibility
Solution Approach 1:
The patent transforms the static spacing structure into a dynamic one. Instead of using constant spacing throughout, the system implements variable spacing that adapts to the number of characters visible in the window. This dynamic approach allows the window height to be minimized while ensuring characters remain fully visible, as the spacing automatically contracts when multiple characters are displayed and expands when a single character is shown.
3Quantity of substance
If the window height is reduced to accommodate more data, then the quantity of displayed information increases, but intermediate values may not be displayed correctly
Solution Approach 1:
The patent ensures accurate display of intermediate values by implementing dynamic spacing adjustment. When intermediate values cause multiple characters to be visible in the window, the spacing automatically contracts to accommodate them without compromising legibility. This dynamic response ensures that intermediate values are displayed correctly with full character visibility, maintaining display precision while maximizing the quantity of information shown.

AI summary
An embodiment of the invention relates to a method for managing the display of a rotary indicator on a digital screen, the method making it possible to permanently display in a window at least one value of the indicator in the form of characters, the values scrolling vertically in the window, a distance d defining a spacing between two characters of two successive values. The distance d varies between a value dmini when two successive values are visible in the window and a value dmaxi when a single value is visible in the window.
