Vertical Rotating Grilling Frame for Clean Multi-Level Cooking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing grilling devices, such as skewers, face issues with meat juices and fat dripping onto other food items, leading to taste impairment and health risks, and require additional steps for grilling food of different sizes, which is time-consuming and labor-intensive. Additionally, clamping mechanisms can damage the skin of grilled food during removal.
Innovation Solution
A grilling device with a U-shaped holding frame and rotatable design about a vertical axis, featuring spaced-out support elements to prevent contact between food items, allowing for easy loading and quick removal, and an antimicrobial surface treatment to prevent bacterial growth. The device includes detachable support elements and trays to catch juices and fat, ensuring even grilling and improved hygiene.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If food items are arranged closely together on horizontal skewers to maximize grilling capacity, then space utilization is improved, but meat juices and fat drip onto underlying food causing taste impairment and health risks
Solution Approach 1:
The patent transitions from horizontal skewer arrangement to vertical arrangement around a central rotating axis. This dimensional change allows food items to be positioned one above another without direct contact, preventing juice contamination while maintaining high grilling capacity through efficient vertical space utilization.
Solution Approach 2:
The grilling device divides the cooking space into multiple independent levels with spacing between them. Each food item is positioned on its own level, separated by gaps that prevent dripping juices from contaminating food below, while the modular structure maintains overall grilling efficiency.
2Productivity
If multiple food items of different sizes are grilled simultaneously on horizontal skewers, then productivity is improved, but additional work steps are required to remove finished items and re-s skewer unfinished items
Solution Approach 1:
The patent implements a rotating skewer mechanism that allows continuous rotation during grilling. This dynamic arrangement enables all food items on a skewer to be evenly cooked simultaneously, and when one item is finished, the skewer can be easily rotated out and replaced without disturbing other items, eliminating the need for complex removal and re-s skewering operations.
3Stability of the object's composition
If food items are clamped tightly on skewers to secure them during grilling, then stability is improved, but the skin of grilled food is displaced or injured during removal
Solution Approach 1:
The patent uses localized securing elements positioned at specific points on the food item rather than continuous clamping. The skewer design incorporates discrete attachment points that hold the food securely during rotation and grilling, but allow easy release at the end without exerting continuous pressure that would damage the skin or cause displacement during removal.
