Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If compensation circuit is disposed near terminal portions in prior art Category 6 jacks, then the jack structure is simple, but electrical characteristics are degraded at higher speeds
Solution Approach 1:
The patent moves the compensation circuit from the traditional terminal portion area to the contact portion area, effectively changing the spatial dimension and location of the circuit placement. This dimensional repositioning allows the compensation circuit to be closer to the signal entry point, improving electrical characteristics at high speeds while maintaining structural simplicity through the flexible substrate integration
2Adaptability or versatility
If switch mechanism is added to support both Category 6 and Category 7, then adaptability is improved, but device complexity and risk of open circuits increase
Solution Approach 1:
The patent designs a universal jack structure where the same contact block and compensation circuit configuration supports both Category 6 and Category 7 standards. The flexible substrate with integrated compensation circuitry provides a unified solution that eliminates the need for separate switch mechanisms, achieving multi-functionality without additional complexity
3Productivity
If multiple pairs of contacts are used for data transmission, then communication capacity is improved, but cross-talk and external interference increase
Solution Approach 1:
The patent introduces a compensation circuit as an intermediary element between the contact pairs and the terminal portions. This compensation circuit, implemented on a flexible substrate, acts as a mediator that actively compensates for and reduces cross-talk and external interference effects, enabling multiple pairs to transmit data at high speeds without signal degradation

AI summary
A jack capable of handling both Category 6 and Category 7 speed communications. The jack includes a shield, a housing disposed in the shield and a contact block disposed in the housing. The contact block includes a base member and a plurality of contacts carried by the base member. Each contact includes a contact portion effective to touch a corresponding contact of a plug when the plug is inserted into the jack, a first end portion effective to be inserted into a circuit board, and a second end portion. A flexible substrate is connected to the second end portion, the substrate including a compensation circuit for the jack.
