To attract fish, fishermen generally use lures, which offer high catch rates and environmental friendliness. Fishermen who use lures must constantly move the line to make the lures move back and forth, stimulating fish attacks on the lures and increasing catch rates. However, each person can only fish with one pole at a time. This study uses the Theory of Inventive Problem Solving (TRIZ) to conduct a trend analysis of fishing lure improvement and construct a technical contradiction matrix, by using an active scent releasing device connected with a buoy lure. This device has a camera inside that uses scent as a fish attractant. The scent is released by a control button on the fishing pole. When fishing with this pole, fishermen can watch the screen attached to the fishing pole and observe the fish to decide the timing of scent release. This fishing pole with an active scent release lure can be effective in improving fishing performance. It is also different from traditional fishing methods in that one person can control more than one hand pole at a time.
