Solution Overview
Problem
Conventional bidirectional electrical connectors have high manufacturing costs and low reliability due to the need for precise orientation during docking, which can lead to user errors and connection failures.
Innovation Solution
A bidirectional duplex electrical connector design featuring two insulation seats with elastically movable terminals and a metal housing, allowing for dual-positional and bidirectional docking with reduced manufacturing complexity and increased reliability through the use of loose-pin type and female-fork type terminals for ground and power connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional bidirectional electrical connector design is used, then manufacturing cost is high, but reliability is low
Solution Approach 1:
The electrical connector is divided into two insulation seats (first and second), each containing separate contact terminals. This segmentation allows independent positioning and connection of each seat, enabling bidirectional docking without requiring precise overall orientation. The first insulation seat and second insulation seat can be independently assembled and positioned, reducing manufacturing complexity while maintaining reliable connections in both directions.
2Manufacturing precision
If mistake-proof function is implemented, then connection orientation is ensured, but user operation becomes difficult
Solution Approach 1:
The connector employs asymmetric design within each insulation seat - the first insulation seat has first contact terminals arranged in a specific orientation, while the second insulation seat has second contact terminals arranged differently. This asymmetric arrangement within seats allows the overall connector to accept connections from both directions, eliminating the need for users to worry about orientation while maintaining precise contact alignment through the asymmetric terminal configurations.
3Ease of operation
If dual-positional docking is enabled, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The patent merges the functionality of two separate single-direction connectors into one bidirectional connector by combining a first insulation seat with first contact terminals and a second insulation seat with second contact terminals. Both seats are integrated within the same connector body and can be independently connected to corresponding terminals on the mating connector, enabling dual-positional docking without requiring two separate connector designs. This merging approach achieves bidirectional functionality while maintaining relatively simple individual seat structures.
