Analog Timepiece Information Display Plate Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional analog information display devices face challenges in quickly switching between multiple information items without compromising readability, particularly when displaying multiple information items on a dial plate, which leads to design constraints and user confusion.
Innovation Solution
An analog electronic timepiece with a dial plate, a rotatable date display plate, and an information display plate, where the information display plate can be moved between two positions to selectively display different information items through a display window, allowing quick switching without rotating the date display plate, thereby maintaining readability and reducing design complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single rotary disk is rotated with a step motor to display multiple information items selectively, then multiple information items can be displayed, but it takes time to display a particular information item owing to limitations of rotation speed
Solution Approach 1:
The display system is divided into two independent rotary disks: a date display plate and an information display plate. Each disk can rotate independently to display different information items, allowing parallel operation and reducing the time required to switch between information types.
Solution Approach 2:
The information display plate is designed to rotate independently from the date display plate, enabling dynamic switching between date information and additional information items without waiting for the entire display system to reconfigure.
2Adaptability or versatility
If multiple information items are displayed on a dial plate, then information completeness is improved, but design constraints increase and user identification difficulty arises
Solution Approach 1:
The dial plate design is segmented into a base dial plate with date markings and a separate rotatable information display plate with additional information items. This separation allows each component to have a simpler, more focused design while collectively providing comprehensive information display capability.
Solution Approach 2:
Additional information items are displayed by adding a vertical dimension through a rotatable overlay plate, rather than cluttering the horizontal dial plate surface with multiple marks. This dimensional approach maintains design simplicity while increasing information capacity.
3Loss of information
If a rotatable information display plate is used to selectively expose information, then unnecessary information can be hidden, but the mechanism increases device complexity
Solution Approach 1:
The date display function and additional information display function are merged into a single integrated mechanism where the rotatable information display plate serves dual purposes: displaying date information when rotated to certain positions and displaying additional information items when rotated to other positions.
Solution Approach 2:
The information display plate is designed as a universal component that can display multiple types of information (date, day, additional data) depending on its rotational position, eliminating the need for separate mechanisms for each information type.

AI summary
An information display device includes a dial plate having a display window; a rotatable date display plate provided under the dial plate and having dates to be selectively displayed through the window; an information display plate provided between the dial plate and the date display plate and including a display portion having an information item on a top surface thereof; an information display plate driver capable of moving the information display plate to any one of first and second positions. When the information display plate is in the first position, the display portion does not lie just under the window and a date in a position corresponding to the window is displayed through the window. When the information display plate is in the second position, the display portion is in a position corresponding to the window.
