Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional separate connection boxes are used for each motor, then each motor can be connected independently, but the cabling complexity increases and maintenance becomes more difficult
Solution Approach 1:
Multiple connection boxes are merged into a single integrated connection box that serves multiple motors. The connection box contains multiple hybrid connector parts arranged parallel to each other, allowing multiple cables to be connected and routed through the same housing, thereby reducing overall system complexity and improving ease of operation.
Solution Approach 2:
The connection box is designed as a universal component that can accommodate multiple hybrid connector parts and serve multiple motors simultaneously. It integrates functions of multiple separate connection boxes while providing a standardized interface for hybrid cable connections.
2Adaptability or versatility
If T-pieces are used for cable connections, then cable routing is possible, but the device complexity and number of components increases
Solution Approach 1:
The function of T-pieces for cable routing is merged into the connection box housing itself. The housing contains multiple hybrid connector parts arranged parallel to each other, allowing cables to be routed through the housing without requiring separate T-piece components, thereby reducing the total number of components while maintaining routing capability.
3Volume of moving object
If heat-generating components are concentrated in one area, then the motor structure is compact, but heat dissipation becomes difficult
Solution Approach 1:
The connection box housing is segmented into multiple regions with multiple hybrid connector parts arranged parallel to each other. This segmentation allows heat from multiple cable connections to be distributed across different areas of the housing, improving heat dissipation while maintaining a compact overall structure.
Solution Approach 2:
The hybrid connector parts are arranged in a parallel configuration within the connection box housing, utilizing three-dimensional space efficiently. This spatial arrangement allows heat to dissipate in multiple directions through the housing walls, improving thermal management while maintaining compactness.
4Ease of repair
If maintenance requires access to different sides of motors, then all motors can be serviced, but the ease of maintenance decreases
Solution Approach 1:
The hybrid connector parts are arranged asymmetrically within the connection box housing, with all connectors positioned to be accessible from a single side. This asymmetric arrangement within the housing allows maintenance personnel to access all connections from one side, improving ease of repair while maintaining operational consistency.

Function Achieved in This Case
This design improves operability and maintenance by simplifying cabling connections, reducing maintenance costs, and enhancing heat dissipation, allowing for efficient operation and reduced complexity in systems with multiple electric motors.
Implementation Method 1
the hybrid connector parts are arranged in the lower part, so that their housing parts can be made of metal, as a result of which the heat can even be passed on from the lower part to these housing parts
Implementation Method 2
the surface area of the motor that dissipates heat to the environment is increased, thus improving heat dissipation
