Gas-Tight Tritium Light Source Housing with Integrated Colored Ring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sighting devices require laborious manual application of bright colored rings for improved visibility during daylight and twilight, and adhesive bonding for light source mounting, which is time-consuming and not easily exchangeable.
Innovation Solution
A light source with a colored annularly encircling body around its longitudinal center axis, integrated into the housing, providing a visible colored ring in daylight and a central light-emitting point at night, and a non-destructive, frictionally engaging connection for easy mounting and exchangeability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a bright colored ring is manually applied to the holder for improved visibility during daytime, then visibility is improved, but production time increases considerably
Solution Approach 1:
The patent combines the colored ring function with the light source housing itself, eliminating the need for separate manual application of colored rings to the holder. The housing is manufactured with the colored ring integrated as part of its structure, thereby improving visibility while reducing production time by removing the manual coloring step.
Solution Approach 2:
The colored ring is pre-integrated into the housing during manufacturing rather than being applied manually during assembly. This preliminary action of incorporating the visual enhancement feature into the base component eliminates subsequent manual operations and reduces overall production time.
2Reliability
If adhesive bonding is used for light source mounting, then secure mounting is achieved, but exchangeability and automated mounting become difficult
Solution Approach 1:
The patent divides the mounting system into separable mechanical components that can be assembled and disassembled without adhesive. The light source and holder are designed with complementary mechanical features (such as recesses and protrusions or threaded connections) that provide secure mounting while allowing easy separation for exchangeability and automated assembly.
3Reliability
If adhesive bonding is used for light source mounting, then secure mounting is achieved, but automated mounting becomes difficult
Solution Approach 1:
The mounting system is segmented into separate mechanical components with standardized interfaces that can be assembled by automated equipment. The design eliminates adhesive bonding in favor of mechanical fastening methods (such as snap-fits, threads, or interference fits) that are suitable for automated assembly processes while maintaining secure mounting.
4Illumination intensity
If a colored ring is manually applied to the holder, then visibility during daylight is improved, but the production process becomes more complex
Solution Approach 1:
The colored ring function is merged with the housing structure, eliminating the need for separate manual application processes. The housing is manufactured with the colored ring as an integrated feature, either through multi-material injection molding, co-molding, or other manufacturing techniques that combine multiple functions into a single component, thereby simplifying the production process while maintaining improved daylight visibility.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enhances visibility with a seamless transition between colored ring and light-emitting point, and allows for adhesive-free, automated mounting and easy exchange of the light source, reducing production time and improving usability.
