Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing self-luminous bodies, such as tritium gas lights, are limited by their shape due to an unfavorable ratio of surface area to thickness, restricting their design flexibility and applications.
Innovation Solution
A method for producing self-luminous bodies involving a housing with depressions and feeder openings, where a fluorescent or phosphorescent layer is applied and excited by decay radiation, allowing for the creation of self-luminous bodies with customizable shapes and structures, including planar designs, by using a medium that emits decay radiation within a gas-tight cavity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If traditional tritium gas lights are used, then they provide self-luminous functionality, but they have an unfavorable ratio of surface area to thickness and are restricted in shape
Solution Approach 1:
The housing is divided into at least two separable housing parts that can be joined together to enclose a cavity. This segmentation allows for flexible assembly and enables the creation of planar and custom-shaped self-luminous bodies with optimized surface area to thickness ratios, directly resolving the shape flexibility limitation of traditional monolithic tritium lights.
Solution Approach 2:
The invention transitions from traditional three-dimensional bulky tritium lights to planar, two-dimensional self-luminous bodies. By creating flat housing parts that enclose a cavity when joined, the design achieves a large surface area relative to thickness, enabling applications like watch crystals and keyboard backgrounds where thin, flat lighting is required.
2Adaptability or versatility
If housing parts are joined to enclose a cavity, then self-luminous bodies with customizable shapes can be produced, but the housing must be connected in gas-tight manner with additional feeder openings
Solution Approach 1:
Feeder openings are intentionally left open during the assembly process before the cavity is sealed. This preliminary action allows for the introduction of fluorescent/phosphorescent substances and tritium gas through the openings, after which the openings are closed and welded. This approach enables customizable cavity contents without requiring permanent complex sealing structures during assembly.
Solution Approach 2:
The feeder openings serve as intermediary access points that facilitate the introduction of cavity contents (fluorescent substance, phosphorescent substance, or tritium gas) during assembly. These openings are temporary features that enable versatile cavity configuration while maintaining relatively simple housing structures, as they can be closed and welded after use.

AI summary
A process produces self-illuminating bodies, in which a recess is made in a housing part of a housing and a fluorescent and/or phosphorescent layer and/or a mask is arranged on a boundary wall of a cavity which is formed by joining the housing parts together. The housing parts are connected in a gastight manner, with at least one feed opening from outside into the cavity remaining open. Furthermore, a medium emitting decaying radiation is introduced through the at least one feed opening into the cavity, the decaying radiation being intended to illuminate the fluorescent and/or phosphorescent layer. Furthermore, a self-illuminating body and also the use thereof are specified.
