Solution Overview
Problem
The existing motor design with an integrally formed driving shaft and rotary shaft results in increased size, complex sensor connection structures, reduced reliability of sensed information, and difficulties in precise position control and component replacement.
Innovation Solution
A motor design where the driving shaft and rotary shaft are separately formed, with sensors mounted outside the housing and directly connected to a control module, allowing for simplified sensor operation and reduced motor size, featuring a sensor connecting part with a body and terminal connected to the control part, and a clutch actuator with a piston and lead screw for improved assembly and component compatibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the driving shaft of the actuator and the rotary shaft of the motor are integrally formed, then the motor and actuator can be manufactured together in one housing, but the size of the motor is increased and precise position control becomes difficult
Solution Approach 1:
The patent divides the motor and actuator into separate components with distinct housings. The motor housing contains the motor assembly while the actuator housing contains the actuator assembly, allowing independent manufacturing and assembly. This segmentation enables precise position control of the motor shaft while maintaining ease of manufacture through modular assembly processes.
2Measurement precision
If sensors are connected to the control module in the existing structure, then the state of the actuator can be measured, but the connecting structure is complex and reliability of sensed information is reduced
Solution Approach 1:
The patent introduces a sensor connecting part as an intermediary component that includes a sensor mounting part and terminal. This connecting part provides a dedicated interface for mounting sensors and establishing electrical connections to the control module, simplifying the overall connection structure while maintaining measurement precision through proper signal transmission pathways.
3Force
If a large-sized bearing is installed at the motor side to overcome the load acting on the actuator, then the load can be supported, but the size of the motor is increased
Solution Approach 1:
The patent segments the load support function from the motor assembly by providing a separate actuator housing with its own bearing structure. The actuator bearing is specifically designed to handle the actuator load, allowing the motor to maintain a compact size while the overall system achieves the required load bearing capacity through the combined motor-actuator assembly.
