Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple optical apparatuses are installed to output different structured lights, then diversified functions are provided, but the volume of the electronic product increases
Solution Approach 1:
The patent combines multiple optical apparatuses into a single integrated device. A beam splitting unit divides the light from one light source into multiple beams, which are then directed to different structured light generation modules. This merging approach allows multiple functions to be provided while reducing the overall volume of the electronic product.
Solution Approach 2:
The optical apparatus is designed to perform multiple functions using a single system. The beam splitting unit and multiple structured light generation modules enable the device to output different structured lights (e.g., line patterns, dot patterns, grid patterns) simultaneously, making the optical apparatus universal and eliminating the need for separate devices.
2Adaptability or versatility
If multiple optical apparatuses are installed to output different structured lights, then diversified functions are provided, but the weight of the electronic product increases
Solution Approach 1:
The patent merges multiple optical apparatuses into a single integrated device, sharing common components such as the light source and beam splitting unit. This reduction in component quantity directly decreases the weight of the electronic product while maintaining diversified functions through multiple structured light generation modules.
Solution Approach 2:
The single optical apparatus is designed with multi-functionality, capable of generating various structured light patterns through different modules. This universal design eliminates the need for multiple separate heavy devices, thereby reducing the overall weight while providing diverse functions.
3Adaptability or versatility
If multiple optical apparatuses are installed to output different structured lights, then diversified functions are provided, but the portability of the electronic product deteriorates
Solution Approach 1:
The patent integrates multiple optical apparatuses into a compact single device, significantly improving portability. The beam splitting unit and modular structured light generation modules are arranged within a small form factor, making the electronic product easy to carry and move while maintaining diversified functions.
Solution Approach 2:
The compact optical apparatus provides universal functionality for different structured light applications, eliminating the need to carry multiple separate devices. This multi-functional integration directly enhances portability and ease of operation while maintaining adaptability to various detection needs.
4Volume of stationary object
If a single optical apparatus is used to output multiple structured lights, then the volume is reduced, but the complexity of the optical system increases
Solution Approach 1:
The patent applies segmentation by dividing the optical system into distinct functional modules: a light source, a beam splitting unit, and multiple structured light generation modules. Each module performs a specific function, and the modular architecture simplifies the overall system design and assembly, reducing the perceived complexity despite the integrated multi-functionality.
Solution Approach 2:
The beam splitting unit acts as an intermediary component that bridges the single light source and multiple structured light generation modules. It divides the incoming light beam into multiple separate beams, each directed to a different module, thereby simplifying the optical path design and reducing the complexity of coordinating multiple light sources.

Function Achieved in This Case
Enables the provision of multiple functions in a single, compact optical apparatus, enhancing spatial and temporal recognition resolution through interference fringes formed by coherent structured light patterns, thus maintaining portability and miniaturization.
Implementation Method 1
the beam splitting unit is a polygonal block-type beam splitter... The first light beam is generated after a first-portion beam of the source beam is reflected by the first surface. The second light beam is generated after a second-portion beam of the source beam is reflected by the second surface.
Implementation Method 2
The collimating unit is arranged between the light source and the beam splitting unit. After a light beam passes through the collimating unit, the light beam is collimated by the collimating unit and directed to the beam splitting unit.
Implementation Method 3
The first structured light generation module includes a first diffractive optical element... The second structured light generation module includes a second diffractive optical element
Implementation Method 4
The first structured light generation module includes a first refractive optical element... The second structured light generation module includes a second refractive optical element
Implementation Method 5
the first structured light and the second structured light are coherent with each other. When the first structured light and the second structured light are projected on a projection surface, at least one interference fringe is formed on the projection surface.

AI summary
An optical apparatus includes an illumination module, a first structured light generation module, a second structured light generation module and a beam splitting unit. The beam splitting unit is arranged between the illumination module, the first structured light generation module and the second structured light generation module. When a source beam from the illumination module is received by the beam splitting unit, the source beam is split into a first light beam and a second light beam. The first light beam is propagated in a direction toward the first structured light generation module. The second light beam is propagated in a direction toward the second structured light generation module. After the first light beam passes through the first structured light generation module, a first structured light is generated. After the second light beam passes through the second structured light generation module, a second structured light is generated.
