Binocular Prism Module Vertical Light Source Placement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing binoculars capable of measuring distance face design challenges due to the placement of laser diodes, which compromises the appearance by not allowing the use of organic light-emitting diodes for reticle generation.
Innovation Solution
The binocular design positions the light source and receiver above or below the prism module, utilizing a prism module with a roof prism, a first prism, and a second prism, allowing for the integration of an organic light-emitting diode by optimizing the space usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the laser diode is arranged near the ocular to avoid the OLED, then the OLED can be used for reticle generation, but the appearance design of the ocular is compromised
Solution Approach 1:
The patent moves the laser diode from the traditional lateral arrangement near the ocular to a vertical arrangement above or below the prism module. This dimensional change in component placement allows the OLED to be properly integrated into the ocular assembly for reticle generation while maintaining a clean, optimized appearance design of the ocular.
2Measurement precision
If the laser diode and laser receiver are disposed near the objective modules, then the distance measurement function is achieved, but the space for OLED integration is limited
Solution Approach 1:
The patent relocates the laser diode and laser receiver from the horizontal plane near the objective modules to the vertical dimension above or below the prism module. This spatial reconfiguration preserves the distance measurement functionality while creating adequate space within the ocular assembly for integrating the OLED to generate the reticle.
3Shape
If the laser diode is positioned to optimize appearance, then the ocular design is improved, but the distance measurement function may be affected
Solution Approach 1:
By positioning the laser diode vertically above or below the prism module rather than laterally near the ocular, the patent achieves both goals: the ocular maintains an optimized appearance design without laser components interfering with its structure, while the distance measurement function remains fully operational through the prism module's light path configuration.
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
This configuration enhances the appearance design by enabling the use of organic light-emitting diodes for reticle generation, improving the binocular's aesthetic and functional capabilities.
Implementation Method 1
The first light beam enters the third prism, is reflected by the third prism, enters the second prism through the seventh surface, passes through the sixth surface of the second prism, enters the first prism through the third surface, and is reflected by the second surface of the first prism to leave the prism module

AI summary
A prism module includes a first prism including a first surface, a second surface and a third surface, a roof prism including a roof surface and a fourth surface, a second prism including a fifth surface, a sixth surface and a seventh surface, and a third prism including a light access surface, a first reflecting surface and a second reflecting surface. A light source is disposed above the second prism and adjacent to the first and the roof prisms. A light beam emitted by the light source enters and is reflected by the third prism, enters the second prism through the seventh surface, passes through the sixth surface, enters the first prism through the third surface, and is reflected by the second surface to leave the prism module. The light beam leaving the prism module is parallel to a baseline passing through the first, the second and the fourth surfaces.
