Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for measuring the salinity of salt water in large salt fields are inefficient due to difficulties in accurately observing the salinity from a distance or moving closer to measurement devices, leading to time-consuming and inaccurate results.
Innovation Solution
A system utilizing a float that changes floating height in response to salinity changes, with a radio wave reflecting mechanism that allows for remote and accurate measurement of salinity through intensity changes in the reflected wave, enabling easy and precise salinity measurement across large areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If observation is performed from a distance, then measurement time is reduced, but measurement precision deteriorates
Solution Approach 1:
The patent applies a reflective material with specific reflectivity characteristics to the float. This material reflects radio waves with intensity that varies according to the float's floating height, enabling remote detection of salinity changes through radio wave intensity measurements rather than visual observation of scales.
Solution Approach 2:
The patent replaces the mechanical visual observation system with a radio wave-based detection system. Instead of requiring visual inspection of graduated scales, the system uses radio waves to detect the float's position and convert it into measurable intensity signals for remote salinity measurement.
2Measurement precision
If visual observation of scales is performed, then salinity can be measured, but it requires time and effort to move closer to devices
Solution Approach 1:
The patent introduces radio waves as an intermediary to transfer information about the float's position and the liquid's salinity. The reflective material on the float modulates the radio wave intensity according to its floating height, allowing remote measurement without physical proximity to the device.
3Measurement precision
If graduated scales are used for measurement, then salinity can be determined, but the area required for effective observation becomes large
Solution Approach 1:
The patent transitions from two-dimensional visual observation of graduated scales to a different measurement dimension using radio wave intensity. The reflective material converts the float's vertical position into variable radio wave intensity, enabling measurement information to be transmitted through intensity modulation rather than spatial scale visualization.
