Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If traditional electrical motor structure is used, then motor function is achieved, but space for accommodating additional components is insufficient
Solution Approach 1:
The patent implements a hollow rotor structure where the rotor assembly contains an internal cavity that can accommodate optical components and light sources. This nesting approach allows additional functional components to be positioned within the existing motor structure without increasing overall volume, thereby resolving the contradiction between limited space and need for component integration.
Solution Approach 2:
The motor assembly is designed to perform multiple functions: it provides motor drive functionality while simultaneously housing and rotating optical components for scanning and light sources for status indication. This multi-functionality allows the single motor assembly to replace what would traditionally require separate components, addressing the versatility requirement.
2Adaptability or versatility
If optical components are added to the motor, then scanning and indication functions are enabled, but device complexity increases
Solution Approach 1:
The patent combines the motor drive function with optical component rotation function by coupling the optical components to the rotor assembly. This merging of functions allows the motor to simultaneously provide mechanical drive and rotate optical components for scanning, reducing overall system complexity compared to using separate motors for each function.
Solution Approach 2:
By nesting optical components within the hollow rotor structure, the patent integrates multiple functional elements into a compact arrangement. This nesting reduces the number of separate assemblies required and simplifies the overall device structure while maintaining the desired versatility.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables the integration of optical components and light sources within the motor, allowing for enhanced functionality such as scanning and status indication without additional space, improving the motor's ability to drive UAVs and perform range-finding tasks.
Implementation Method 1
When an electrical current passes through the winding wires, a magnetic field is formed which then rotates the rotor relative to the stator
Implementation Method 2
The bearing assembly can rotate relative to the rotor assembly and/or the stator assembly while maintaining the relative locations of the rotor/stator assemblies
