Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a fixed electric connection port position is used, then the connection structure is simple, but the user convenience deteriorates due to limited plugging directions
Solution Approach 1:
The electric connection port is segmented into multiple independent conductive strips (first conductive strip and second conductive strips) arranged at different positions within the concave trench. Each conductive strip can independently establish electrical connection with corresponding elastic contacts, enabling multi-position plugging capability while maintaining structural simplicity
Solution Approach 2:
The electric connection port structure is designed to perform multiple functions: it can accept connectors plugged from different directions (frontward or backward) and establish reliable electrical connections regardless of plugging position. The universal design allows the same port structure to accommodate various connector positions without requiring additional components
2Ease of operation
If the electric connector can be plugged at any position, then the user convenience improves, but the connection reliability may deteriorate due to variable contact positions
Solution Approach 1:
The electric connector incorporates elastic contacts (first elastic contact and second elastic contacts) that can dynamically adjust their position and apply contact force. When the connector is plugged at any position within the concave trench, the elastic contacts automatically deform to establish reliable electrical connection with the conductive strips, ensuring connection reliability regardless of plugging position
Solution Approach 2:
The elastic contacts utilize changes in physical parameters (deformation, contact force) to maintain reliable electrical connection. As the connector is inserted at different positions, the elastic contacts change their deformation state and contact pressure to ensure consistent electrical connection quality across all valid plugging positions

Function Achieved in This Case
This design enhances user convenience by enabling flexible plugging directions and secure power transmission during charging, allowing the connector to be plugged into any position along the port's extending direction.
Implementation Method 1
The electric connector includes a first elastic contact and a second elastic contact both of which are exposed and protruded outward. The first elastic contact corresponds to the first conductive strip, and the second elastic contact corresponds to the at least one second conductive strip.

AI summary
The present disclosure discloses an electronic device including an electronic apparatus and an electric connector. The electronic apparatus includes an electric connection port. The electric connection port includes a concave trench, a first and second conductive strips are disposed in the concave trench. The first conductive strip and the second conductive strip respectively extend along an extending direction of the concave trench. The electric connector includes a first and second elastic contacts which are exposed and protruded outward. When the electric connector is plugged into the electric connection port, the first elastic contact is in contact with the first conductive strip, and the second elastic contact is in contact with the second conductive strip. The electric connection port may accommodate the electric connector, so that the electric connector may be selectively plugged to any position on the electric connection port along the extending direction of the concave trench.
