Innovation Solution

An aircraft equipped with a transmitter capable of sending electromagnetic waves of specific wavelengths and rotary wings, autonomously flying over a field to collect environment information such as water content, temperature, and pH using sensor elements that change properties in response to environmental conditions, allowing for efficient data collection without the need for frequent battery replacements or manual data retrieval.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If an enormous number of field observation devices are located on extensive farmland to obtain environment information distribution, then measurement precision is improved, but device complexity and labor requirements increase significantly

Engineering Contradiction:
