Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional LiDAR systems require complex and time-consuming optical path adjustments due to the interdependence of components, leading to a large volume and cumbersome design.
Innovation Solution
A modular design for the laser transceiving module with the emitting optical system, laser splitting module, and receiving optical system arranged in separate channels within a cavity, with the emitting and receiving modules positioned outside, allowing for simplified light adjustment and reduced volume.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional assembly methods with interdependent components are used, then the laser transceiving module can be assembled, but the light adjustment becomes complex and time-consuming
Solution Approach 1:
The patent divides the laser transceiving module into independent functional modules: emitting module, receiving module, and processing module. Each module contains its own optical components and can be assembled and adjusted independently, eliminating the interdependence problem in conventional designs and simplifying the light adjustment process.
Solution Approach 2:
The patent implements preliminary light adjustment and positioning within each independent module before final assembly. The emitting and receiving modules are pre-adjusted to ensure optimal optical alignment, which simplifies the overall system integration and reduces adjustment time during final assembly.
2Stability of the object's composition
If complex fixing structures are used to secure component positions, then the components can be firmly fixed, but the module volume increases
Solution Approach 1:
The patent integrates the fixing function directly into the module housing structure rather than using separate complex fixing mechanisms. The housing is designed with built-in positioning features and mounting structures that securely hold components in place while minimizing the overall volume required for fixation.
Solution Approach 2:
The patent applies localized fixing structures only where needed within the module, rather than using a comprehensive complex fixing system throughout. The independent module design allows for targeted, minimal fixing structures that provide adequate stability without adding excessive volume.
