Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional network connectors with gold-plating contacts suffer from significant noisy signal interference due to the induction of positive and negative electric charges, which are not adequately addressed by existing designs, leading to inferior transmission characteristics.
Innovation Solution
The network connector design incorporates a gold-plating contact module with crossed fourth and fifth contacts between the contact area and the circuit board to offset positive and negative electric charges, applying the principle of voltage balancing earlier in the gold-plating contacts, reducing interference and enhancing transmission performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the fourth and fifth gold-plating contacts are arranged parallel to each other, then the device complexity is low and manufacturing is easy, but noisy signal interference occurs due to induction of positive and negative electric charges
Solution Approach 1:
The patent applies asymmetry by crossing the fourth and fifth gold-plating contacts instead of arranging them parallel. This asymmetric crossing arrangement changes the spatial relationship between the contacts, allowing the positive and negative electric charges to offset each other and reduce noisy signal interference while maintaining manufacturing feasibility.
Solution Approach 2:
The patent implements preliminary anti-action by designing the crossing arrangement of the fourth and fifth contacts in advance, before signals are transmitted. This pre-configured asymmetric layout creates an offsetting effect on electric charges that proactively counteracts noisy signal interference, rather than attempting to correct it after the fact.
2Device complexity
If the gold-plating contacts are arranged in conventional parallel order, then the device structure is simple, but transmission performance deteriorates due to noisy signal induction
Solution Approach 1:
The patent introduces asymmetry into the contact arrangement by crossing the fourth and fifth gold-plating contacts. This asymmetric configuration reduces noisy signal induction and improves transmission reliability, while the overall device structure remains relatively simple and manageable.
Solution Approach 2:
The patent transitions from a two-dimensional parallel arrangement to a three-dimensional crossing configuration. By utilizing the spatial dimension more effectively, the contacts cross each other in space, creating an asymmetric layout that reduces electromagnetic interference while maintaining a compact structure.
3Device complexity
If voltage balancing is performed only on the circuit board, then the gold-plating contacts can be arranged simply, but the ability to offset noisy signals is insufficient
Solution Approach 1:
The patent performs voltage balancing action in advance by arranging the fourth and fifth gold-plating contacts in a crossed configuration before signals are transmitted. This preliminary asymmetric arrangement creates an inherent offsetting effect on electric charges, enhancing noisy signal compensation before signals reach the circuit board.
Solution Approach 2:
The patent combines two approaches: the asymmetric crossing arrangement of gold-plating contacts and the voltage balancing design on the circuit board. By merging these two measures, the system achieves enhanced noisy signal offsetting capability while maintaining reasonable overall device complexity.

AI summary
A network connector, it is provided with an insulation base provided in a front face thereof with a socket for insertion of a plug on a network electric line, and a gold-plating contact module is inserted in the insulation base. The gold-plating contact module has eight gold-plating contacts which are extended out of a printed circuit board. The tailing ends of the gold-plating contacts remote from the circuit board are laid out according to a sequence from a first one to an eighth one of the gold-plating contacts in the socket to form a contact area for electrically connecting a plug on a network electric line. The fourth gold-plating contact and the fifth gold-plating contact are crossed with each other at an area between the contact area and the circuit board, this forms offsetting action on positive and negative electric charges of noisy signals between the crossing area and the circuit board to enhance transmitting performance of said network connector.
