Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If connectors are miniaturized to reduce size, then compactness is improved, but high-frequency operation becomes difficult and noise interference increases
Solution Approach 1:
The patent employs nested shielding structures where an inner shielding layer is placed within the connector cavity and an outer shielding layer surrounds it, creating multiple levels of electromagnetic protection. This nested arrangement effectively blocks high-frequency noise and interference while maintaining compact connector dimensions.
Solution Approach 2:
The patent introduces grounding pieces as intermediary elements that connect the shielding layers to the ground. These grounding pieces act as mediators to dissipate electromagnetic interference and noise, enabling the miniaturized connector to operate reliably at high frequencies by providing controlled impedance and noise pathways.
2Reliability
If automatic bolt lock connection mode is used to ensure firm contact, then connection reliability is improved, but operation difficulty increases due to inability to easily unlock
Solution Approach 1:
The patent implements a self-service unlocking mechanism where the connector can be easily unlocked by pressing a release button that automatically actuates the locking mechanism. The pressing member translates user pressure into automated unlocking action, eliminating the need for complex manual operations while maintaining reliable automatic locking during normal use.
Solution Approach 2:
The patent employs dynamic locking and unlocking mechanisms where the locking state can be easily transitioned between locked and unlocked positions. The elastic member and pressing member work together to provide a dynamic system that maintains firm locking during operation but allows quick, easy unlocking when needed through simple button pressing.

AI summary
The invention provides an easy lock connector with unlock structure applied to a flat wire and a circuit board. The flat wire has a notch and a ground wire on the two sides of a head end respectively. The easy-lock connector includes an upper housing, a lower housing, a rubber core and a terminal. After the notch of the flat wire is buckled by a stopper of the lower housing, by pressing a pressing member of the upper housing, the pressing member applies an external force to an elastic member of the lower housing to deform the elastic member. An extension arm of the lower housing is linked by the elastic member to cause the stopper to act in one direction so as to release the state of the stopper from locking the gap. In another embodiment, the easy-lock connector can also achieve an electromagnetic shielding effect by adding a shielding iron shell.
