Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional connector uses directional design with mechanical lead angle and inclined plane for combination, then the connector can transmit power and signals effectively, but the connector becomes prone to damage during incorrect insertion and lacks blind insertion function
Solution Approach 1:
The patent applies asymmetry by designing the male head and female seat with non-symmetrical electrode arrangements and positioning structures. The male head includes a first circular body with electrodes at specific positions, while the female seat has a corresponding asymmetric electrode layout. This asymmetric design ensures that correct insertion aligns the electrodes properly, while incorrect insertion prevents contact, thereby providing damage resistance during insertion while enabling blind insertion capability.
Solution Approach 2:
The patent inverts the conventional approach by making the connector non-directional through symmetric circular designs with multiple electrode groups arranged in concentric circles. Instead of relying on mechanical lead angles and inclined planes for directional guidance, the connector allows insertion from either direction with electrodes designed to make contact regardless of rotation angle, thereby achieving both damage resistance and blind insertion functionality.
2Volume of moving object
If a conventional connector is miniaturized to reduce size, then the connector can be applied in compact electronic products, but the connector becomes more susceptible to damage from excessive force during incorrect insertion
Solution Approach 1:
The patent applies nesting by arranging multiple electrode groups in concentric circular patterns within the male head and female seat. The first electrode group is arranged in a first circular pattern, the second electrode group in a second circular pattern, with additional electrode groups nested in intermediate regions. This nested circular arrangement allows the compact connector to maintain multiple functional electrodes while minimizing overall size, and the distributed electrode layout ensures that incorrect insertion does not concentrate force on single vulnerable points.
Solution Approach 2:
The patent segments the connector into multiple independent electrode groups (first electrode group, second electrode group, third electrode group, fourth electrode group) with distinct functions and positions. Each electrode group can be independently designed with optimal spacing and arrangement, allowing the miniaturized connector to achieve high integration while maintaining damage resistance through distributed load bearing across multiple segmented elements rather than concentrated stress on single components.
3Reliability
If a connector uses fool-proof design to prevent incorrect insertion, then the connector can avoid damage, but the fool-proof structure is still easily damaged by excessive force during incorrect insertion attempts
Solution Approach 1:
The patent applies self-service by designing the male head and female seat with self-aligning electrode arrangements and positioning structures that automatically guide correct insertion without requiring external fool-proof mechanisms. The asymmetric electrode layouts and circular body designs enable the connector to self-correct insertion orientation, eliminating the need for additional protective structures that would be vulnerable to excessive force. The connector protects itself through its inherent geometric and electrical design rather than relying on separate fool-proof components.
4Adaptability or versatility
If a circular connector uses multiple electrode groups in concentric arrangements to achieve non-directional connections, then the connector enables blind insertion and simultaneous power and signal transmission, but the device complexity increases
Solution Approach 1:
The patent applies universality by designing the circular connector with multiple electrode groups that can simultaneously perform multiple functions: the first and second electrode groups transmit power, while the third and fourth electrode groups transmit control signals. The concentric circular arrangement allows the same basic structure to accommodate different electrode configurations and functions, enabling the connector to adapt to various application requirements without increasing fundamental design complexity. The modular electrode group design allows selective activation of different electrode pairs for different operational modes.

AI summary
The present invention provides a circular connector, which comprises a male head and a female seat. The male head provides a first circular body, a third circular body, a first electrode group and a third electrode group. The female seat provides a first base, a second circular body, a fourth circular body, a second base, a second electrode group and a fourth electrode group. The second base, the fourth circular body, the second circular body and the first base are arranged outwards from the center point of the female seat. The male head is combined with the female base, so that the third circular body is inserted between the second circular body and the fourth circular body to realize non-directional electrical connection.
