Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional resistors are used to divide voltage, then voltage division function is achieved, but the circuit area occupied is large and signal quality is poor (low-definition with noise)
Solution Approach 1:
The patent transitions from traditional planar resistor layouts to a three-dimensional folded resistor structure. The resistance bar is folded back on itself multiple times within a compact footprint, utilizing the third dimension (vertical space) to achieve long resistance paths without occupying large planar area. This dimensional transformation resolves the contradiction by providing both compact area occupation and maintained signal quality through adequate resistance length.
Solution Approach 2:
The resistor structure implements a nested configuration where the resistance bar folds within itself, creating a compact nested pattern. Each fold nests part of the resistance path within the spatial envelope of previous sections, maximizing the use of available three-dimensional space while maintaining the required resistance value and signal integrity.
2Volume of moving object
If circuit dimensions are shrunk, then miniaturization is achieved, but traditional resistors become less applicable due to space constraints
Solution Approach 1:
By folding the resistance bar into three-dimensional space, the patent enables resistors to fit within miniaturized circuit volumes while maintaining functional performance. The folded structure achieves long resistance paths within small footprints, making resistors applicable in modern compact electronic devices where traditional planar resistors would be too large.
3Adaptability or versatility
If multiple voltage options are needed, then more resistor configurations are required, but this increases device complexity and space requirements
Solution Approach 1:
The folded resistor structure incorporates multiple tap points along the resistance bar, enabling a single resistor component to provide multiple voltage division ratios. By selecting different pairs of contact pads on the folded structure, engineers can obtain various resistance values and voltage divisions without requiring multiple separate resistors, thus achieving multi-functionality while reducing overall device complexity.
