Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If a long handle or rod structure is used for remote operation, then the operation distance is extended, but the pressing force for depressing the spray nozzle becomes insufficient
Solution Approach 1:
A lever mechanism is introduced as an intermediary between the pusher and the spray nozzle button. The lever amplifies the pushing force from the pusher through mechanical advantage, converting a small remote pushing force into sufficient pressing force on the nozzle button while maintaining remote operation capability.
Solution Approach 2:
The mechanism transforms the linear pushing motion from the pusher into rotational motion of the lever, and then into vertical pressing motion on the nozzle button. This dimensional transformation allows force amplification while maintaining remote operation distance.
2Force
If a complex mechanism is used to generate sufficient pressing force, then the pressing force requirement is met, but the device weight increases making it unsuitable for aerial vehicles
Solution Approach 1:
The lever mechanism uses the pushing force from the pusher itself to generate the required pressing force through mechanical advantage, without requiring additional heavy actuators or force-generating components. The system serves itself by converting the remote operation force into sufficient pressing force through intelligent mechanical design.
Solution Approach 2:
The patent replaces complex heavy-duty actuators with a simple lever mechanism that provides mechanical advantage. This substitution achieves the required pressing force using minimal weight, making the device suitable for aerial vehicle mounting.
3Device complexity
If a fixed spray location mechanism is used, then the structure is simplified, but the adaptability to different locations and purposes is reduced
Solution Approach 1:
The spray device is mounted on a mobile unit that can move to different locations dynamically. The lever mechanism and pusher assembly can also adjust their positions and angles, allowing the device to adapt to different spray locations and purposes while maintaining relatively simple structural components.

AI summary
A remote operation spray device configured to depress-operate a spray nozzle of a spray device from a remote location. Device generates adequate pushing force required for depression and, by achieving weight reduction of the device proper, enables easy mounting on an aerial vehicle or other mobile unit. Device includes a main body fixedly attached to a mobile unit, a holder fixedly retaining a spray cartridge and a spray mechanism for jetting spray. The spray mechanism includes a base member, a depressing member pivotably attached to the base member for pressing down a spray nozzle, a pushed member provided at a distal end of the depressing member, and a pusher installed on the base member for pushing the pushed member to move horizontally. The horizontal pushing action of the pusher pushes and moves the pushed member to pivot the depressing member and press the spray nozzle vertically downward.
