Spit roaster for foods
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional spit roasters face challenges in controlling the smoking and burning of foods due to fat drippings onto hot coals, and they are often large and inflexible, limiting their use and roasting options.
Innovation Solution
A spit roaster with angled, inverted V-shaped spits and adjustable L-shaped supports allows for variable roasting heights and flexibility in placement, using a grill or fish pan for food arrangement, and can be easily assembled and moved to adapt to different spaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a metal griddle is used to prevent fat from falling onto hot coals, then the harmful effect of fat dripping is eliminated, but the roasting method changes from grill to griddle which is not desirable
Solution Approach 1:
A drip tray is introduced as an intermediary component between the food and the hot coals. The drip tray collects fat drippings and directs them away from the coals, preventing harmful smoking and burning while maintaining the open-grill roasting method. This mediator solves the contradiction by providing a solution that protects against harmful effects without changing the desired roasting approach.
2Stability of the object's composition
If conventional spit roasters are made as large and fixed installations, then structural stability is improved, but flexibility and adaptability to different spaces are reduced
Solution Approach 1:
The spit roaster is divided into separate modular components including the spit assembly and the support structure with adjustable legs. This segmentation allows the components to be assembled and disassembled easily, enabling adaptation to different spaces and placement locations while maintaining structural stability during use through the interconnected design of the modules.
Solution Approach 2:
The support structure incorporates adjustable legs that can be modified in length and position during operation. This dynamic adjustability allows the roaster to adapt to various space configurations and stability requirements, resolving the contradiction between fixed stability and flexible adaptability.
3Use of energy by moving object
If the air inlet is regulated to control heat output, then energy control is improved, but the ability to control fat ignition and smoking remains insufficient
Solution Approach 1:
The drip tray serves as a mediator that specifically addresses fat ignition control independent of air inlet regulation. By collecting and redirecting fat drippings away from the hot coals, the drip tray prevents smoking and burning effects that cannot be controlled merely by adjusting air flow, thus supplementing the existing heat control mechanism.
4Ease of manufacture
If spits are made with simple shapes for easy manufacture, then manufacturing simplicity is improved, but rigidity and heat deformation resistance are reduced
Solution Approach 1:
The spit is designed with an asymmetric inverted V-shape cross-section rather than a simple circular or square form. This asymmetric geometry provides enhanced rigidity and resistance to heat deformation while remaining manufacturable using standard metal forming processes. The inverted V-shape creates structural strength without requiring complex manufacturing steps.
