Solution Overview
Problem
Existing methods for roasting food over an open fire, such as using a long stick or extended fork, require constant rotation to achieve even cooking, which can be tedious and difficult for children and adults to master.
Innovation Solution
A fire fishing pole device with a rod, wire, and flipping mechanism that allows for easy rotation of food items, featuring a handle, bifurcated wire, and a counterbalance weight to ensure even cooking and fun outdoor cooking experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a long stick or extended fork is used to roast food, then the food can be cooked over an open fire, but constant rotation is required which is tedious and difficult to master
Solution Approach 1:
The device employs a dynamic flipping mechanism with a weight that automatically rotates the food 180 degrees when the rod is moved in a jigging motion. This transforms the static holding action into a dynamic automatic flipping system, eliminating the need for constant manual rotation while maintaining even cooking.
Solution Approach 2:
The flipping mechanism is self-actuating through the weight's response to the jigging motion of the rod. The system serves itself by using the user's basic rod movement to trigger the automatic 180-degree flip, without requiring the user to manually rotate or control the flipping action.
2Reliability
If a simple stick is used for roasting, then the device is simple, but it cannot achieve even cooking without constant rotation
Solution Approach 1:
A weight is attached to the rod to create a counterbalance system. When the rod is moved in a jigging motion, the weight's position changes cause the flipping mechanism to automatically rotate the food 180 degrees, ensuring even cooking through gravity-assisted automatic flipping.
Solution Approach 2:
The device is divided into distinct functional segments: the rod for holding and jigging, the wire for suspending the food, and the flipping mechanism with weight for automatic rotation. This segmentation allows each component to perform its specific function independently while working together to achieve even cooking.
3Strength
If the wire is made rigid to withstand heat, then the food can be held securely, but the flipping mechanism requires precise positioning
Solution Approach 1:
The wire is pre-configured with a bifurcated structure and the flipping mechanism is pre-positioned at specific locations along the wire. The weight is attached at a predetermined position to ensure proper leverage and flipping action. This preliminary positioning simplifies the final assembly and ensures reliable operation.
Solution Approach 2:
The shaft acts as an intermediary component that connects the weight to the wire's bifurcated structure. It mediates between the weight's gravitational force and the wire's rigid structure, enabling the flipping action while maintaining the structural integrity required for heat resistance.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Facilitates even cooking of food items over a fire with reduced user effort, providing a fun and efficient outdoor cooking experience by automatically rotating the food through a 180-degree motion.
Implementation Method 1
The weight acts as a counter balance and causes the mechanism to flip when the weight is jigged to a position that is beyond a position parallel to the wire

AI summary
A device for roasting food of fire, the device designed to mimic a fishing pole and having a rod, a wire, and a flipping mechanism. The wire is attached to an end of the rod and extends a fixed length culminating in a bifurcation at its end. The bifurcation includes apertures to receive a shaft of the flipping mechanism. The flipping mechanism includes a pair of rails and skewers located at the ends of the shaft and a weight centrally located on the shaft between the bifurcation, wherein the weight acts as a counter balance to flip the flipping mechanism when the rod is moved up and down or tilted.
