Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional connection methods are used to connect the electric motor to the gearbox, then the connection is secure, but the assembly time is increased and centering is difficult
Solution Approach 1:
The hollow cylindrical collar regions are pre-formed on both the flange part and connection part, enabling preliminary centering alignment before the actual connection is made. This preliminary action of centering reduces the time and complexity of the connection process while ensuring secure assembly.
Solution Approach 2:
The hollow cylindrical collar regions act as intermediary elements that facilitate the connection between the electric motor and gearbox. These collar regions provide a guided insertion path and centering mechanism, mediating the connection process to achieve both quick assembly and secure fixation.
2Manufacturing precision
If complex connection mechanisms are used to ensure precise alignment, then the centering precision is improved, but the device complexity increases
Solution Approach 1:
The hollow cylindrical collar regions utilize cylindrical (curved) geometry to provide automatic centering through radial symmetry. This curved surface design allows the connection parts to self-align during insertion, achieving precise centering without complex adjustment mechanisms or multiple alignment features.
