Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing motor assemblies in LiDAR systems face challenges in achieving accurate torque and rotation speed due to complex assembly processes and tooling-dependent positioning, leading to fluctuations in assembling accuracy.
Innovation Solution
A motor assembly design for LiDAR that includes a mounting bottom plate with a stator seat positioning groove, a circuit board assembled in a positioning manner, and a wound stator sleeved on a stator positioning protrusion, allowing for tooling-free positioning and improved relative position accuracy, thereby simplifying the assembly process and enhancing torque and rotation speed accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If tooling-dependent positioning is used in the assembly process, then the assembly process can be standardized, but the assembling accuracy fluctuates and the process becomes complex
Solution Approach 1:
The motor assembly components (stator seat, mounting bottom plate, wound stator) are designed with self-positioning structures including positioning grooves, positioning protrusions, and positioning holes that enable tooling-free positioning. The components position themselves during assembly through these built-in geometric features, eliminating the need for external positioning tools and achieving consistent high accuracy without complex assembly processes.
2Measurement precision
If traditional assembly methods are used, then the assembly process is established, but the relative position accuracy of components cannot be effectively controlled
Solution Approach 1:
Positioning grooves, positioning protrusions, and positioning holes are pre-designed and pre-formed on the motor assembly components during manufacturing. These preliminary positioning features ensure that when assembly occurs, the components automatically achieve precise relative positioning without requiring additional measurement or adjustment operations, thereby improving both relative position accuracy and assembly ease.
3Manufacturing precision
If precise positioning structures are added to improve accuracy, then the assembling accuracy improves, but the device complexity increases
Solution Approach 1:
The positioning functions are merged into the existing structural components of the motor assembly. The stator seat, mounting bottom plate, and wound stator incorporate positioning grooves, protrusions, and holes as integral parts of their structures rather than as separate added features. This merging approach achieves precise positioning without significantly increasing overall structural complexity.
