Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional LiDAR systems face complexity and accuracy issues due to the use of separate motor and mirror components, which can lead to torsion, twisting, and vibration, affecting the redirection of light pulses, and require mechanical systems for scanning, limiting the system's efficiency and reliability.
Innovation Solution
An integrated mirror motor galvanometer that repurposes a motor rotor with a mirror face, eliminating separate components and reducing mechanical complexity by integrating the mirror with the motor, thereby improving scanning accuracy and reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate motor and mirror components are used for light pulse redirection, then the system can perform scanning function, but mechanical complexity increases and scanning accuracy decreases due to torsion, twisting, and vibration
Solution Approach 1:
The patent combines the motor rotor and mirror into a single integrated component where the mirror is directly mounted on the rotor. This eliminates separate motor and mirror components, reducing mechanical complexity and eliminating torsion, twisting, and vibration between separate parts, thereby improving scanning accuracy and reliability
2Productivity
If multiple separate components are used for scanning, then the system can achieve scanning coverage, but the number of moving parts increases reducing system efficiency
Solution Approach 1:
The integrated mirror motor galvanometer merges the motor rotor and mirror into one component, significantly reducing the number of moving parts. This eliminates the need for separate motor mounting structures, mirror mounting structures, and multiple alignment mechanisms, thereby improving scanning efficiency and system reliability
3Ease of manufacture
If separate motor and mirror components are used, then component manufacturing is simplified, but assembly precision and alignment accuracy deteriorate
Solution Approach 1:
By integrating the mirror directly onto the motor rotor, the patent eliminates complex assembly and alignment procedures between separate components. The mirror and rotor are manufactured as a single precision component, ensuring accurate alignment is built-in during manufacturing rather than requiring complex post-assembly alignment procedures
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
The integrated design enhances scanning efficiency and accuracy by reducing mechanical issues, allowing for more precise redirection of light pulses and enabling higher resolution scanning with fewer moving parts.
Implementation Method 1
The integrated mirror motor galvanometer repurposes a rotor of a motor to include a mirror face that redirects the light pulses interfacing therewith. Thus, when the rotor oscillates, so does its mirror face.

AI summary
Embodiments discussed herein refer to an integrated mirror motor galvanometer. The integrated mirror motor galvanometer repurposes a rotor of a motor to include at least one mirror face that redirects the light pulses interfacing therewith. This way, when the rotor oscillates along its range of rotation, the at least one mirror face also oscillates.
