Optical Binoculars Dual Light Source Illumination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional optical binoculars lack versatility and user-friendliness, particularly in night vision applications, as they do not effectively illuminate targets at varying distances, limiting the user's field of view and comfort during use.
Innovation Solution
The optical binocular incorporates a first light source assembly with a plano-convex lens for long-range illumination and a second light source assembly with a convexo-plane lens and condensing cup body for close-range illumination, allowing for adjustable focal lengths and improved emission angles, along with a liquid-crystal display panel and ergonomic design for enhanced viewing experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single light source assembly is used in conventional optical binoculars, then the device structure remains simple, but the binoculars cannot effectively illuminate targets at varying distances, limiting the field of view and user comfort
Solution Approach 1:
The patent divides the illumination system into two separate light source assemblies: a first light source assembly with a first lens for long-range illumination, and a second light source assembly with a second lens for close-range illumination. This segmentation allows each assembly to be optimized for its specific function, resolving the contradiction between versatility and complexity by creating specialized components rather than attempting to make a single assembly handle all scenarios.
Solution Approach 2:
The patent creates a multi-functional illumination system where two light source assemblies work together to provide comprehensive illumination coverage at both long and short distances. This universal approach allows the binoculars to adapt to various viewing conditions without requiring the user to switch devices or make manual adjustments, effectively achieving versatility through coordinated multiple components.
2Illumination intensity
If the focal length of the lens is increased for long-range illumination, then the long-range light emission is improved, but the emission angle becomes narrower, reducing close-range illumination effectiveness
Solution Approach 1:
The patent applies local quality by assigning different optical characteristics to different light source assemblies. The first lens has a longer focal length optimized for long-range illumination with a narrower emission angle, while the second lens has a shorter focal length optimized for close-range illumination with a wider emission angle. Each assembly's optical properties are locally optimized for its specific function, resolving the contradiction between long-range intensity and overall angular coverage.
3Adaptability or versatility
If the focal length of the lens is decreased for close-range illumination, then the emission angle widens, but the long-range light emission capability is reduced
Solution Approach 1:
The patent segments the illumination function into two specialized assemblies: one optimized for close-range with a shorter focal length and wider emission angle, and another optimized for long-range with a longer focal length and narrower emission angle. This segmentation resolves the contradiction by allowing each assembly to excel at its designated range without compromise.
Solution Approach 2:
The patent creates a dynamic illumination system where the appropriate light source assembly can be activated based on the required viewing distance. The system adapts to different operational conditions by selectively engaging the first or second light source assembly, providing optimal performance whether the user needs close-range or long-range illumination.

AI summary
An optical binocular is provided, including a main body, a lens module, a display module, a first light source assembly and a second light source assembly. The lens module is disposed on one side of the main body. The display module is disposed in the main body and electrically connected to the lens module, and is configured to display an image. The first light source assembly includes a first light source and a first lens, and emits a first light. The second light source assembly includes a second light source and a second lens, and emits a second light. The first light source emits a long-range light through the first lens, and the second light source emits a close-range light through the second lens, wherein the focal length of the first lens is greater than the focal length of the second lens.
