Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional gravimeters are used for gravity measurement, then measurement precision is improved, but device complexity and cost increase significantly
Solution Approach 1:
The patent introduces an intermediary computational model that simulates gravitational acceleration based on celestial body positions and inertial forces. Instead of directly measuring gravity with complex instruments, the system uses a computer to calculate expected gravitational acceleration from known astronomical data, serving as a mediator between observable quantities (celestial positions) and the target measurement (gravity).
Solution Approach 2:
The patent replaces complex mechanical gravity measurement systems (springs, superconductors, atomic interferometers) with a computational approach. The measurement system substitutes mechanical sensing with mathematical modeling, using computer calculations of celestial gravitational forces to determine local gravity without physical contact or complex mechanical components.
2Measurement precision
If traditional gravimeters are used for gravity measurement, then measurement precision is improved, but ease of operation deteriorates
Solution Approach 1:
The system performs self-calibration and self-measurement by using the Earth's own gravitational field and celestial bodies as reference standards. The computational model automatically calculates gravitational acceleration from publicly available astronomical ephemerides, eliminating the need for manual calibration procedures or expert operation. The system serves itself by using natural celestial mechanics as its measurement reference.
Solution Approach 2:
The measurement system achieves multi-functionality by using a single computational framework that can determine gravity at any location on Earth given celestial body positions. The same algorithm works universally across different geographic locations and time periods, unlike traditional gravimeters that require location-specific calibration and maintenance.
3Measurement precision
If traditional gravimeters are used for gravity measurement, then measurement precision is improved, but cost increases to hundreds of thousands or millions of dollars
Solution Approach 1:
The patent replaces expensive, fragile, high-precision mechanical instruments with inexpensive computational algorithms and standard computer hardware. Instead of investing in million-dollar gravimeters with delicate components, the system uses readily available computing resources to achieve the same measurement function, dramatically reducing cost while maintaining precision through mathematical calculation.

AI summary
The disclosure provides an indirect method for measuring gravity based on the synthesis of gravitational forces generated by celestial bodies, gravitational forces generated by the Earth and other inertial forces, resulting in changes in the gravitational acceleration of the position to be measured. By regularly monitoring the direction change of gravitational acceleration of the position, the gravity measurement result of such position is deduced. When monitoring the direction change of gravitational acceleration, measure the direction of gravity at each moment, and obtain observation data on the direction change of gravitational acceleration. According to its own coordinates, the approximate value of the acceleration vector caused by the current position of the Earth is obtained as the initial solution, and the estimation data of gravity acceleration direction change is calculated, combined with the observation data of gravity acceleration direction change, and the gravity measurement result is obtained by iterative linearization.
