Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a fixed connector design is used to ensure structural stability, then manufacturing precision is improved, but adaptability to positional deviations deteriorates
Solution Approach 1:
The connector design incorporates a movable insulator that can shift position relative to the fixed insulator, transforming the rigid fixed structure into a dynamic system. The movable insulator is guided by bent portions of contact pieces that allow controlled movement in the horizontal direction, enabling the connector to adapt to positional deviations while maintaining electrical connection functionality.
Solution Approach 2:
The connector is divided into two distinct parts: a fixed insulator that maintains structural stability and a movable insulator that accommodates positional variations. This segmentation allows each part to perform its specialized function - the fixed part ensures manufacturing precision while the movable part provides adaptability to positional deviations.
2Adaptability or versatility
If a floating connector design is used to accommodate positional deviations, then adaptability is improved, but connection reliability deteriorates due to improper fitting
Solution Approach 1:
The movable insulator provides controlled dynamic adjustment capability, allowing the connector to adapt to positional deviations through guided movement along the bent portions of contact pieces. This controlled mobility ensures proper fitting and maintains connection reliability while accommodating positional variations.
Solution Approach 2:
The bent portions of contact pieces serve as intermediary elements that mediate between the fixed and movable insulators. These bent portions provide guided movement paths that ensure the movable insulator shifts properly to accommodate positional deviations while maintaining reliable electrical connections.
3Strength
If rigid contact pieces are used to ensure structural strength, then strength is improved, but ease of operation deteriorates due to stress concentration
Solution Approach 1:
The contact pieces incorporate bent portions that enable controlled movement and flexibility. This dynamic design allows the contact pieces to deform elastically during assembly, reducing stress concentration and making the connector easier to assemble while maintaining sufficient structural strength for reliable operation.
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
The connector design effectively accommodates positional deviations between substrates, reducing stress on contact points and improving connection reliability by allowing the movable insulator to move parallel to the substrate plane, thus enhancing assembly workability and preventing conduction failures.
Implementation Method 1
contacts that include a first contact portion that is in contact with the other connector, a second contact portion, and a coupling portion that couples the first contact portion and the second contact portion. The first engagement portion, the first bent portion, the coupling portion, the second bent portion, and the second engagement portion are arranged in a connecting direction

AI summary
A connector includes a plurality of contacts. Each of the contacts includes a first engagement portion, a second engagement portion, a first bent portion, a second bent portion, and a coupling portion. A second angle formed by a reference straight line and a second straight line is smaller than a first angle formed by the reference straight line and a first straight line, where the first straight line is a straight line passing through an end of the first bent portion on the first engagement portion side and an end of the first bent portion on the coupling portion side, and the second straight line is a straight line passing through an end of the second bent portion on the coupling portion side and an end of the second bent portion on the second engagement portion side.
