Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The complexity and cost of production in LiDAR optical systems are increased due to the need for multiple optical elements and complex assembly processes, which require numerous parts and lengthy adjustment procedures.
Innovation Solution
An optical system design that integrates optical elements within a bracket's accommodation cavity, using a restrictive assembly to secure the elements in place, thereby simplifying assembly and reducing the number of parts, and utilizing a light-transmitting sheet for protection and alignment, allowing direct mounting and reducing production costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If optical elements are assembled in a lens barrel first and then mounted on a bracket, then the optical system achieves proper alignment and positioning, but the production complexity and assembly complexity increase significantly
Solution Approach 1:
The patent merges the lens barrel and bracket into a single integrated bracket structure. The bracket directly provides both the mounting function and the optical alignment function through integrated features such as the optical element receiving cavity and positioning structures, eliminating the need for separate lens barrel components and reducing assembly steps.
Solution Approach 2:
The bracket is designed to perform multiple functions simultaneously: it serves as the mounting structure for optical elements, provides alignment through integrated positioning features, and replaces the traditional lens barrel function. This multi-functionality reduces the total number of components and simplifies the overall assembly process.
2Reliability
If multiple separate components are used in the optical system, then the system achieves proper functionality, but the number of parts increases and production costs increase
Solution Approach 1:
The patent combines multiple separate components (lens barrel, bracket, mounting structures) into a single integrated bracket assembly. This merging reduces the total number of parts while maintaining all necessary optical functions through carefully designed integrated features.
Solution Approach 2:
The integrated bracket performs multiple functions that previously required separate components: mounting optical elements, providing alignment, and serving as the structural support. This multi-functionality reduces part count while ensuring the optical system maintains its required functionality and reliability.
3Stability of the object's composition
If traditional lens barrel assembly is used, then optical elements are properly secured, but the production time and assembly time increase
Solution Approach 1:
The bracket is pre-designed with integrated positioning cavities and alignment features that automatically guide optical elements into their correct positions during assembly. This preliminary preparation of the bracket structure eliminates the need for time-consuming adjustment and alignment procedures during the actual assembly process.
Solution Approach 2:
By merging the mounting and alignment functions into a single integrated bracket, the patent enables faster assembly as workers no longer need to separately attach lens barrels and adjust alignments. The single integrated component can be installed in one operation, significantly improving productivity while maintaining stable optical element positioning.
