Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If multiple ions are trapped simultaneously to reduce measurement time, then measurement speed is improved, but ion interference occurs leading to measurement errors
Solution Approach 1:
The ion trap is divided into multiple independent trap regions along the x-axis, with each region capable of trapping and measuring individual ions independently. The planar ion trap structure creates distinct potential wells separated by sufficient distance to prevent ion interactions, allowing parallel measurement of multiple ions without interference while maintaining measurement accuracy.
2Measurement precision
If a single ion is trapped and measured sequentially to ensure accuracy, then measurement precision is maintained, but measurement time increases
Solution Approach 1:
Multiple ion measurement systems are merged into a single planar ion trap device. The trap simultaneously holds multiple ions in separate regions, and the microwave and laser irradiation systems are configured to irradiate multiple ions concurrently. This merging enables parallel angle measurements of multiple ions in the same device, significantly improving measurement speed while maintaining precision through proper spatial separation.

AI summary
The present invention reduces measurement time. A gyroscope of the present invention includes a planar ion trap part, a microwave irradiation part, a laser irradiation part and a measurement part. The planar ion trap part includes two rf electrodes and two DC electrode rows, and forms ion traps that trap one ion on a substrate, a normal direction of the surface of the planar ion trap part corresponds to a z direction. The rf electrodes are disposed in the x direction on the substrate at a predetermined interval. The DC electrode rows are disposed in the x direction on the substrate so as to sandwich the two rf electrodes. The DC electrode rows each include at least five DC electrodes in the x direction. The trapped ions are spaced so as not to interfere with each other. The microwave irradiation part irradiates the ions with π/2 microwave pulses.
