Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a single reset voltage is applied to all particle groups, then the operation is simple, but particles with different threshold voltages cannot be separated and reset independently, leading to non-uniform distribution
Solution Approach 1:
The patent segments the particle groups by their threshold voltage characteristics, assigning different reset voltages to different particle groups. This segmentation allows each particle group to be reset independently according to its specific threshold voltage, achieving uniform distribution while maintaining manageable complexity through systematic voltage assignment.
Solution Approach 2:
The patent applies the principle of local quality by tailoring the reset voltage to each specific particle group's threshold voltage requirements. Instead of a uniform approach, each particle group receives a customized voltage level appropriate to its characteristics, enabling precise control over particle migration and final distribution uniformity.
2Manufacturing precision
If reset voltages are applied sequentially to each particle group, then independent control is achieved, but the resetting time increases
Solution Approach 1:
The patent employs periodic action by applying reset voltages in a sequential manner to different particle groups. Each particle group receives its designated reset voltage in turn, allowing independent control and precise resetting while managing the overall process time through structured periodic voltage application cycles.
3Productivity
If particles are not properly reset, then the process is faster, but non-uniform particle distribution occurs and color representation becomes inaccurate
Solution Approach 1:
The patent applies parameter changes by adjusting the reset voltage levels according to the specific threshold voltage parameters of each particle group. This parameter optimization ensures that particles are properly reset with accurate color representation while maintaining efficient operation speed through scientifically determined voltage values for each particle type.
