I enjoy designing for special operating environments and have experimented with the modular design approach in this project.

A New Method for Preventing Whale Entanglement Fishing Net
Heroshot for the Anti-tangle Device For Ballen Whales
The project aims to provide fishermen with a simple, effective and inexpensive lightweight fishing gear fitting device that protects whales from entanglement while helping fishermen reduce catch loss due to gear damage.
The most dangerous element is vertical buoy lines which can be placed on a variety of fishing gear. Based on whale habits and fishermen's fishing habits, three functions were developed specifically for buoy lines: visual warning, rope flexibility reducing, and auditory deterrence. Compared to competitive single type (bottom trawl) cordless gear, this product allows for multiple types of gear and switching between them.
Details for the Anti-tangle Device
There are magnets inside the tube closures for easy alignment. The main body is white to increase the possibility of reflecting light underwater, in keeping with the whale’s field of vision.
Each unit has its own pre-set depth and the numbering on the outside of the tube helps the user to know the order in which they are placed.
The lithium batteries are arranged 2 x 3 with two rows connected in series to increase current and three rows connected in parallel to increase voltage. The mechanical seal structure referenced in this product consists of a dynamic ring, a static ring, a spring, two O-rings, bushing and other supporting parts.
Scenario
Workflow: (after the five units have been installed in sequence)
1. automatically start when in the water and go to the preset depth;
2. standby and wait for the signal that the whale is passing;
3. receive the signal, go to the target position and assemble;
4. make a sound deterrent;
5. wait for the whale to leave and return to the position.
The combined length of the units is greater than the circumference of the fins and tail, making it possible to reduce the entanglement of these body parts.
