Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If multiple independent electrostatic attraction force regions are generated by multiplying existing products side by side, then the number of regions increases, but the system complexity and physical space requirements increase significantly
Solution Approach 1:
The patent combines multiple electrode arrays into a single integrated structure where electrodes are arranged in rows and columns forming multiple independent regions. Instead of using separate products side by side, the invention merges them into one unified device that generates multiple electrostatic attraction force regions simultaneously, reducing system complexity while maintaining the desired number of regions.
Solution Approach 2:
The patent transitions from a one-dimensional linear arrangement of electrodes to a two-dimensional matrix arrangement with rows and columns. This dimensional change allows multiple independent electrostatic attraction force regions to be generated within a compact area, increasing the number of regions without proportionally increasing system complexity or physical footprint.
2Quantity of substance
If multiple independent electrostatic attraction force regions are generated by multiplying existing products side by side, then the number of regions increases, but the physical space required increases
Solution Approach 1:
The patent arranges electrodes in a two-dimensional matrix with rows and columns, allowing multiple electrostatic attraction force regions to be generated in a compact area. This dimensional arrangement maximizes the use of available space, enabling more regions to be generated without proportionally increasing the physical footprint compared to linear side-by-side placement.
Solution Approach 2:
The patent creates a nested structure where electrode rows and columns intersect to form multiple independent regions within a single device footprint. The electrodes are positioned such that they share common boundaries and spacing, efficiently nesting multiple functional regions within the available physical space.
3Adaptability or versatility
If electrode arrays are arranged in matrix form on at least two axes, then the number of independent controllable regions increases, but the device complexity increases
Solution Approach 1:
The patent divides the electrode structure into segmented rows and columns that can be independently controlled. Each row and column can be activated or deactivated separately, allowing independent control of multiple electrostatic attraction force regions. This segmentation provides versatility in controlling adhesion at different regions while using a systematic arrangement that manages complexity through modular design.
4Adaptability or versatility
If insulating surfaces are used to separate electrode arrays, then independent control of electrostatic regions is achieved, but the manufacturing complexity increases
Solution Approach 1:
The patent uses thin insulating surfaces or films to separate electrode rows and columns. These thin film insulators are integrated into the electrode array structure, providing electrical isolation between adjacent electrodes while maintaining a compact design. The use of thin films rather than bulky insulating structures simplifies the overall manufacturing process and reduces the complexity of assembling multiple components.
