Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If electric current is used to mitigate unwanted life forms, then mitigation effectiveness is improved, but control and predictability deteriorate due to uncontrolled spark discharges
Solution Approach 1:
A conductivity generator (e.g., water spray or ionization device) is introduced as an intermediary between the electrode and the unwanted life form. This intermediary creates a controlled conductive path through air that is otherwise insulating, allowing precise control of current flow to the target while preventing uncontrolled spark discharges to surrounding areas.
2Productivity
If direct contact between electrode and unwanted life form is made, then current transfer efficiency is improved, but damage to surrounding crops and safety risks worsen
Solution Approach 1:
The conductivity generator creates a localized conductive region only at the position of the unwanted life form through targeted water spray or ionization. This allows high current density precisely where needed (improving transfer efficiency) while maintaining insulating conditions in surrounding areas (protecting crops and reducing safety risks).
Solution Approach 2:
The conductivity generator acts as a spatially selective intermediary that bridges the gap between the electrode and the unwanted life form only at the target location. This enables effective current transfer to the pest while the insulating air gaps to surrounding crops prevent collateral damage.
3Object-affected harmful factors
If air conductivity between electrode and unwanted life form is low, then safety and precision are improved, but current transfer capability worsens
Solution Approach 1:
The system maintains low air conductivity everywhere (ensuring safety and precision) while creating localized high conductivity regions only at the unwanted life form position using the conductivity generator. This spatial differentiation resolves the contradiction between general low conductivity for safety and local high conductivity for effective current transfer.
