Solution Overview

Problem

Existing electronic clocks with optoelectronic display elements struggle to display time in a visually appealing and easy-to-remember manner using only twelve display units, often resulting in static or difficult-to-understand time representations.

Innovation Solution

The electronic clock employs twelve optoelectronic display units arranged around a central point, with lighting means capable of emitting different colors and intensities, controlled by a microprocessor to display hours, 5-minute intervals, and minutes through coordinated light sequences, allowing for dynamic and intuitive time representation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If two rings of light-emitting cells with 60 cells each are used to display hours and minutes, then the time can be displayed in a conventional dial format, but the display device appears overloaded and the number of display elements is excessively high

Engineering Contradiction:
ImproveTime display clarityVSAvoidNumber of display elements
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The time display is segmented into two functional groups using only 12 display elements: one element indicates the hour position while another indicates the minute position. This segmentation allows clear time display without requiring 60 elements per ring, resolving the contradiction between display clarity and device complexity.

Inventive Principle:
Principle #1Segmentation

2Device complexity

If two rings with 12 diodes each are used to display hours and minutes in 5-minute intervals, then the total number of display elements is reduced to 24, but the display becomes static and less visually appealing

Engineering Contradiction:
ImproveNumber of display elementsVSAvoidVisual appeal
Core Design Contradiction:
Device complexityVSEase of operation

Solution Approach 1:

The display system incorporates dynamic characteristics through sequential illumination patterns and color changes. The first and second light-emitting elements can be activated in sequence or simultaneously with different colors, creating a dynamic visual effect that enhances appeal while maintaining low device complexity with only 12 elements.

Inventive Principle:
Principle #15Dynamics

3Device complexity

If four binary coded indicators are used for hours, four for 5-minute intervals and four for 1-minute intervals, then the total number of display elements is reduced to twelve, but the user must translate binary-coded display into time which makes it difficult to understand

Engineering Contradiction:
ImproveNumber of display elementsVSAvoidTime display understandability
Core Design Contradiction:
Device complexityVSEase of operation

Solution Approach 1:

Different functional qualities are assigned to different display elements: one element is dedicated to displaying hour information in a visually intuitive format, another element displays minute information, and they can use different colors or illumination patterns. This local differentiation makes the time display immediately understandable without requiring binary translation, while maintaining only 12 total elements.

Inventive Principle:
Principle #3Local quality

4Device complexity

If an analog display with twelve optoelectronic display elements is used where only one or two elements are active at a time, then the number of display elements is reduced to twelve, but the remaining eleven elements remain passive making the display not particularly appealing

Engineering Contradiction:
ImproveNumber of display elementsVSAvoidDisplay visual appeal
Core Design Contradiction:
Device complexityVSEase of operation

Solution Approach 1:

The system dynamically activates multiple display elements simultaneously or in sequence. The first light-emitting element and second light-emitting element can both be active at the same time with different colors, or activate in a sequential pattern, ensuring that a significant portion of the 12 elements are dynamically engaged rather than leaving 11 passive, thereby enhancing visual appeal while maintaining low complexity.

Inventive Principle:
Principle #15Dynamics

AI summary

The electronic clock (1) has a display device, where twelve opto-electronic display units are arranged. The display units are formed by luminous mediums (2.1 to 2.12), where a control unit is designed to emit light in two different colors or intensities. The control unit has a control medium for display of hours by continuous or cyclic emission of light of a specific color or intensity. An independent claim is also included for a method for time display on an electronic clock.
