Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If two separate connectors are used for power transmission and signal transmission on servo motor, then the functions are clearly separated, but the assembly becomes complicated and manufacturing cost increases
Solution Approach 1:
The patent combines power transmission terminals, signal transmission terminals, and braking terminals into a single integrated connector assembly. The insulating housing contains all three types of terminals arranged in distinct cavities, allowing one connector to replace what would traditionally require multiple separate connectors, thereby simplifying assembly while maintaining functional separation through internal organization.
Solution Approach 2:
The single connector assembly performs multiple functions simultaneously: power transmission through power terminals, signal transmission through signal terminals, and braking control through braking terminals. This multi-functional design eliminates the need for multiple specialized connectors, reducing assembly complexity and manufacturing cost while maintaining reliable functional separation through dedicated cavities for each terminal type.
2Reliability
If two connectors are provided on servo motor for power and signal transmission, then functional requirements are met, but assembling becomes cumbersome and time-consuming
Solution Approach 1:
The patent merges power transmission, signal transmission, and braking functions into a single connector assembly that attaches to the servo motor in one operation. The insulating housing integrates all terminal types, allowing assembly workers to complete what would traditionally require multiple connector installations in a single step, thereby improving productivity without compromising functional completeness.
Solution Approach 2:
The connector assembly is pre-integrated with all necessary terminals (power, signal, and braking) arranged in their final positions within the insulating housing before installation. This preliminary organization of all components in one unit eliminates the need for multiple separate installation steps, streamlining the assembly process and improving productivity while ensuring functional completeness.
3Reliability
If traditional connectors are used on compact servo motor, then standard functionality is provided, but assembly difficulty increases due to limited space
Solution Approach 1:
The patent consolidates multiple terminal functions into a single compact connector assembly with integrated power, signal, and braking terminals. This unified design reduces the overall space requirement compared to multiple separate connectors, making it suitable for compact servo motors while maintaining standard functionality and improving assembly ease through a single installation operation.
Solution Approach 2:
The connector assembly utilizes vertical stacking of cavities (power cavities, signal cavities, braking cavities) within the insulating housing to organize terminals in three-dimensional space. This spatial arrangement maximizes functional integration within a compact footprint, enabling standard functionality in a space-efficient configuration that is easier to assemble on compact servo motors.
4Reliability
If locking mechanism rotates on plug device, then secure connection is achieved, but it becomes unsuitable for applications with compact space above connector
Solution Approach 1:
Instead of rotating the locking mechanism upward as in traditional designs, the patent inverts the locking action by having the locking protrusion on the receptacle device engage with the locking cavity in the plug device from below. The locking cover moves horizontally to secure the connection, eliminating the need for vertical rotation space and making the connector adaptable to compact installations while maintaining connection security.
Solution Approach 2:
The locking mechanism transitions from a static rotational motion requiring vertical space to a dynamic horizontal sliding motion. The locking cover moves laterally to engage or disengage the locking protrusion with the locking cavity, providing secure connection while adapting to compact spaces above the connector by eliminating vertical rotation requirements.
