Solution Overview
Problem
Existing electric weeding systems pose a risk of accidents due to high voltage operations when users fail to wear protective equipment, leading to potential harm.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the electric weeding system is activated without user presence detection, then the operation is simple and fast, but the safety risk increases due to potential accidental activation without protective equipment
Solution Approach 1:
The sensor detects user presence in advance before the system is activated. The control system checks for the presence signal before allowing activation, preventing accidental operation without protective equipment. This preliminary detection ensures safety conditions are met before the high-voltage system operates.
Solution Approach 2:
A sensor acts as an intermediary between the user and the control system. The sensor detects whether the user is wearing insulating boots and transmits this information to the control system, which then decides whether to permit activation. This intermediary component enables safety verification without significantly complicating the overall system.
2Reliability
If a sensor-based user presence detection system is implemented, then safety is improved by preventing activation without protective equipment, but the device complexity increases
Solution Approach 1:
The sensor system automatically detects user presence and communicates this information to the control system without requiring manual input. The control system autonomously decides whether to permit activation based on the sensor signal, reducing the need for complex manual safety protocols and minimizing the operational burden on the user.
3Reliability
If the control system continuously monitors user presence, then safety is enhanced, but the energy consumption increases
Solution Approach 1:
The control system checks for user presence periodically or at key activation moments rather than continuously monitoring. The sensor detects presence and the control system verifies the signal before allowing system activation, maintaining safety while minimizing energy consumption by avoiding constant monitoring.
