Watch Crystal Luminous Display for Dark Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing diving watches are insufficient in displaying information such as orientation and additional data like water depth and diving duration in deep darkness, as luminescent paint only enhances clock time visibility, failing to provide clear recognition of other crucial information.
Innovation Solution
A watch design featuring a light-transmissive member with multiple luminous bodies on both sides, creating a three-dimensional display surface that enhances the visibility and distinguishability of markings and information, allowing users to easily recognize the watch's orientation and additional data in dark environments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If only luminescent paint is applied to the dial and pointer, then the clock time visibility is improved, but the visibility of other information (orientation, water depth, diving duration) deteriorates in deep darkness
Solution Approach 1:
The patent applies luminous bodies to multiple dimensions - on the dial, on the pointer, and crucially on the crystal surface. This multi-layered spatial arrangement creates a three-dimensional display effect where information is distributed across different depths, allowing users to perceive orientation and additional data (water depth, diving duration) simultaneously with clock time in dark environments.
Solution Approach 2:
The luminous display is segmented into multiple independent luminous bodies positioned at different locations and depths - on the dial background, on the pointer, and on the crystal. This segmentation allows different types of information to be displayed separately and simultaneously, with each luminous element contributing to different aspects of the display (time, orientation, depth data).
2Device complexity
If luminescent paint is applied only to the dial and pointer, then the structure remains simple, but the ease of recognizing orientation and additional information deteriorates in dark environments
Solution Approach 1:
By adding luminous bodies on the crystal surface (a different depth dimension from the dial and pointer), the patent creates a three-dimensional luminous display. This dimensional addition enhances ease of recognition in dark environments without significantly complicating the overall device structure, as the crystal already exists as a protective element.
Solution Approach 2:
The crystal serves multiple functions: it protects the internal components and simultaneously acts as a display surface for luminous bodies. This multi-functionality allows the same component to contribute to both structural integrity and information display, avoiding the need for additional separate display elements.
3Loss of information
If a three-dimensional display surface with multiple luminous bodies is created, then the visibility and distinguishability of markings and information is improved, but the device complexity increases
Solution Approach 1:
The light-transmissive member (crystal) is designed to serve dual purposes: maintaining its primary function as a protective cover while simultaneously functioning as a display surface for luminous bodies. This eliminates the need for separate display components, reducing overall device complexity despite the enhanced three-dimensional display capability.
Solution Approach 2:
The patent merges the protective crystal with the display function by positioning luminous bodies directly on the crystal surface. This combination integrates the protective element and information display into a single unified structure, achieving enhanced visibility without proportionally increasing device complexity.

Function Achieved in This Case
The enhanced visibility of the watch's markings and information due to the three-dimensional display surface improves user recognition of the watch's orientation and additional data, such as water depth and diving duration, even in deep darkness.

AI summary
A watch includes crystal, a dial including a marking, a pointer including a luminous body, and a light-transmissive member disposed between the crystal and the dial, the light-transmissive member including a first face facing the crystal and a second face facing the dial, in which the first face is provided with a first luminous member and a second luminous member, and the second face is provided with a third luminous member and a fourth luminous member.
