Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If a traditional power connector system is used, then power transmission is achieved, but the connector has a high profile and is difficult to connect
Solution Approach 1:
The patent transitions from a linear insertion approach to a rotational insertion mechanism, where the connector insert rotates as it enters the receptacle. This dimensional change in the insertion motion allows for a low-profile design while maintaining ease of connection through magnetic guidance and tactile feedback during the rotational mating process.
Solution Approach 2:
The patent replaces traditional mechanical alignment and engagement mechanisms with magnetic fields. Magnets embedded in both the insert and receptacle provide automatic alignment and guidance during insertion, eliminating the need for complex mechanical guide features and reducing the overall connector profile while improving ease of connection.
2Volume of moving object
If the connector receptacle depth is reduced to save space, then device thickness is reduced, but connection reliability may be compromised
Solution Approach 1:
The patent incorporates magnets in advance within both the connector insert and receptacle housing. These pre-positioned magnetic elements perform the alignment and guidance functions before physical contact is made, ensuring reliable connection establishment even in the reduced space of a low-profile design.
Solution Approach 2:
The patent introduces magnetic fields as an intermediary force between the connector insert and receptacle. This magnetic mediator enables reliable connection by providing continuous guidance and attraction forces throughout the insertion process, compensating for the reduced mechanical engagement space in low-profile configurations.
3Ease of manufacture
If a simple connector design is used, then manufacturing is easier, but data signal transmission capability is lost
Solution Approach 1:
The patent designs the connector system to perform multiple functions through a unified structure. The same axisymmetric connector housing and insert that provide mechanical connection and power transmission also incorporate integrated contacts for data signal transmission, eliminating the need for separate data connectors and maintaining manufacturing simplicity.
Solution Approach 2:
The patent merges power transmission and data signal transmission functions into a single connector system. By integrating data contacts within the power connector housing and insert, the design achieves multi-functionality without increasing manufacturing complexity, as the combined structure is manufactured as one unified component rather than multiple separate connectors.

Implementation Method 1
Magnets can be used to help guide a connection between a connector insert and a connector receptacle
Implementation Method 2
Canted springs can be used to provide a tactile response to the insertion of the connector insert into the connector receptacle, to help to secure the connector insert in place when mated
Implementation Method 3
Canted springs can be used to provide a tactile response to the insertion of the connector insert into the connector receptacle, to help to secure the connector insert in place when mated, and to provide an electrical path for a supply voltage, ground, or other bias voltage or signal
