Multi-Directional Electrical Connector Set for EV Battery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing electrical connectors for electric vehicles have limited directional connectivity, requiring users to perform a series of steps to establish a connection, which is inconvenient and time-consuming.
Innovation Solution
An electrical connector set with multi-directional connectivity is designed, featuring a space-end connector with a first outer and inner circular cylinder member and a battery-end connector with a second outer and inner circular cylinder member, allowing for direct one-pass connection without rotation, utilizing signal transmitting terminals and members for simultaneous electricity, controlling, and data signal transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional electrical connectors with specific terminal designs are used, then electrical connection is established, but limited electrical-connection directionality requires repeated insertion, removal, and rotation operations
Solution Approach 1:
The patent employs asymmetric terminal designs where the battery-end electrical connector has signal transmitting terminals arranged in a specific asymmetric pattern, and the space-end electrical connector has corresponding signal receiving terminals positioned to match only in one orientation. This asymmetric configuration ensures that the connectors can only be mated in the correct rotational position, eliminating the need for trial-and-error connection attempts while maintaining ease of operation.
Solution Approach 2:
The patent inverts the traditional approach by designing the connector geometry and terminal arrangements to automatically guide correct orientation through physical compatibility. Instead of relying on user knowledge of correct orientation, the connector shapes are designed so that only the correct orientation allows physical mating, effectively making the wrong orientation physically impossible to achieve.
2Adaptability or versatility
If electrical connectors with specific terminal designs are used to establish connection, then electrical connection is achieved, but multi-directional signal transmission capability is limited
Solution Approach 1:
The patent implements multi-functionality by integrating multiple signal transmitting terminals and signal receiving terminals into a single connector assembly. Each connector simultaneously handles power transmission, ground connection, and multiple signal lines for bidirectional communication. This universal design allows the same connector structure to perform multiple functions (power, data, control signals) without requiring separate connectors for each function, thereby increasing adaptability while managing complexity through integration.

AI summary
Disclosures of the present invention mainly describe an electrical connector set mainly consisting of a space-end electrical connector disposed in a battery accommodating space and a battery-end electrical connector connected to a replaceable battery. The space-end electrical connector is integrated with a first outer circular cylinder member and a first inner circular cylinder member therein. In contrast to the space-end electrical connector, the battery-end electrical connector is also provided with a second outer circular cylinder member and a second inner circular cylinder member therein. By such arrangement, after connecting the battery-end electrical connector with the space-end electrical connector, the outer wall of the first outer circular cylinder member contacts with a circular negative electrode of the second outer circular cylinder member and the outer wall of the first inner circular cylinder member contacts with the circular positive electrode of the second inner circular cylinder member.
