Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If copper wires are directly connected to charging terminals at 180° angle, then electrical connection is established, but mounting becomes difficult and charging socket height becomes excessive
Solution Approach 1:
The patent changes the connection angle from 180° (horizontal) to 90° (vertical), reorienting the copper wire connection in a different spatial dimension. This dimensional change allows the charging socket to be mounted flush with the vehicle body surface, reducing protrusion height and facilitating mounting while maintaining reliable electrical connection.
2Device complexity
If charging socket is designed with direct wire connection, then structure is simple, but quick plug function is not achieved and harness replacement is slow
Solution Approach 1:
The patent segments the charging system into modular components: charging socket, harness assembly with connector, and cable assembly. The connector is divided into a housing portion and a terminal portion that can be independently assembled and replaced. This segmentation enables quick plug functionality and fast harness replacement while maintaining manageable structural complexity through standardized interfaces.
3Object-affected harmful factors
If metal shield is added to connector for electromagnetic shielding, then shielding effect is improved, but processing difficulty and cost increase, assembly time increases, and short-circuiting risk increases
Solution Approach 1:
The patent replaces expensive, difficult-to-process metal shields with a cost-effective plastic housing that incorporates electromagnetic shielding functionality through material selection or structural design. The housing serves as both the mechanical enclosure and the shielding element, eliminating the need for separate metal shield components and reducing processing difficulty, assembly time, and short-circuiting risk while maintaining adequate electromagnetic interference protection.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Each cable is detachably connected to the corresponding terminal by a terminal connector, facilitating disassembly and assembly of the terminals and cables, and fast replacement of the cables. The shield shell effectively shields electromagnetic radiation, reducing interference, and the 90° connection reduces the height of the charging socket, facilitating mounting and wire layout.
Implementation Method 1
The arrangement of a shield shell can effectively shield electromagnetic radiation in the shield shell, reducing electromagnetic interference with other electrical elements
