Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the frequency of operations is increased to improve performance, then productivity is improved, but cross-talk between conductors occurs due to inductive, capacitive or conductive coupling
Solution Approach 1:
The patent applies dynamics by making the operating frequency adjustable rather than fixed. The system dynamically selects and switches between multiple supported frequency levels based on detected line quality conditions. This allows the solid state drive to operate at higher frequencies when line quality is good (improving productivity) while falling back to lower frequencies when cross-talk is detected (avoiding harmful effects).
Solution Approach 2:
The patent changes the frequency parameter of data transmission based on detected line quality. The system monitors signal integrity and adjusts the operating frequency accordingly, selecting from multiple supported frequency levels. This parameter adjustment resolves the contradiction by matching the frequency to the actual electrical conditions of the connection.
2Area of stationary object
If the space between conductors is decreased to fit more systems in standard footprint, then area utilization is improved, but conductive coupling increases due to reduced tolerances
Solution Approach 1:
The patent compensates for reduced physical spacing between conductors by dynamically adjusting the electrical operating parameters. When close spacing causes degraded line quality or cross-talk, the system automatically reduces the operating frequency to a lower supported level, thereby maintaining reliable operation despite the compact physical layout.
3Power
If voltages and currents are increased to improve performance, then power is improved, but conductive coupling and voltage jumping between conductors increases
Solution Approach 1:
The patent applies dynamics by making the power level adjustable based on detected line quality. The system monitors for signs of conductive coupling and voltage jumping, and when these harmful effects are detected, it dynamically reduces the operating frequency and corresponding voltage/current levels to prevent damage while maintaining operation at the highest safe power level.
4Productivity
If the frequency of operations is increased beyond a limited amount, then performance is improved, but inductive, capacitive and conductive coupling occurs within the network
Solution Approach 1:
The patent implements feedback by continuously monitoring line quality during operation and using this information to adjust the operating frequency. The system detects coupling effects through signal quality measurements and feeds this information back to the frequency selection logic, which then adjusts the operating frequency to maintain reliable operation while maximizing productivity.
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
This approach allows solid state drives to operate at higher frequencies without inducing cross-talk, thereby enhancing performance within the constraints of standard form factors and reducing costs.
Implementation Method 1
Inductive coupling occurs, for example, when two conductors are placed in close proximity to one another and a change in a current that is placed in one of the conductors (wires) induces a voltage across the ends of the other wire through electromagnetic induction.
Implementation Method 2
Capacitive coupling occurs when a transfer of energy occurs between two distinct electrical networks. This transfer of energy occurs by means of displacement currents induced by existing electric fields between circuit nodes.
