Engineering Contradiction Analysis
1Speed
If voltage transitions are performed simultaneously among multiple voltage levels, then data transmission speed is improved, but communication quality deteriorates due to signal interference and jitter
Solution Approach 1:
The patent applies preliminary action by delaying the start timing of certain voltage transitions before simultaneous transitions occur. The controller intentionally delays the transition start timing of at least one voltage transition relative to other transitions, preparing the signal paths in advance to avoid interference during the actual simultaneous transition phase, thereby improving communication quality while maintaining transmission speed
Solution Approach 2:
The patent implements dynamics by making the transition start timing variable and controllable. The controller dynamically adjusts the timing of voltage transitions based on signal conditions, allowing the system to adapt between simultaneous transitions (for speed) and staggered transitions (for quality) depending on the communication requirements
2Stability of the object's composition
If voltage transition timing is adjusted to improve communication quality, then signal stability is improved, but device complexity increases due to additional control mechanisms
Solution Approach 1:
The controller is designed with multi-functionality, serving both to manage the overall voltage transition sequence and to implement the timing delay function. This universal controller integrates multiple control tasks into a single device, avoiding the need for separate delay circuits or control units, thereby reducing device complexity while maintaining signal stability
Solution Approach 2:
The patent applies parameter changes by modifying the timing parameter of voltage transitions through the controller. Instead of adding complex hardware, the system achieves signal stability by changing the temporal parameter (transition start timing) of the existing voltage transitions, using software or control logic to adjust timing without increasing device complexity
