Solution Overview
Problem
Existing chafing dish skirts fail to provide effective heat and flame resistance while also blocking wind, leading to potential fire hazards and inconsistent heating during outdoor events.
Innovation Solution
A protective cover member with a basket and tray design, featuring a heat-resistant panel that wraps around the chafing dish, an elastic upper lip, and air vents, combined with a pocket for tools, to contain heat, block wind, and maintain food warmth safely.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional chafing dish skirt is used, then the structure is simple and easy to manufacture, but it fails to provide effective heat and flame resistance while blocking wind
Solution Approach 1:
The panel member is constructed from composite materials including an inner layer of heat-resistant material (such as silicone or rubber) and an outer layer of durable material (such as polyester or nylon fabric). This composite structure provides both heat and flame resistance while maintaining durability and wind-blocking capability, resolving the contradiction between reliability and material complexity.
Solution Approach 2:
The protective cover employs flexible panel members made from heat-resistant materials that can conform to the chafing dish structure while providing thermal protection. The flexible nature allows the cover to maintain its protective function without requiring complex rigid structures, thus improving heat resistance while controlling structural complexity.
2Object-affected harmful factors
If a protective cover is added to block wind, then wind resistance is improved, but the device complexity increases
Solution Approach 1:
The protective cover is divided into multiple separate panel members (front panel, back panel, and side panels) that can be individually attached to the chafing dish. This segmentation allows each panel to be optimized for its specific function (heat resistance, wind blocking) while keeping the overall structure manageable and relatively simple to assemble and manufacture.
Solution Approach 2:
The panel members are designed to serve multiple functions simultaneously: they provide wind blocking, heat resistance, and flame protection all in one component. This multi-functionality reduces the need for additional separate protective elements, thereby improving wind resistance without proportionally increasing device complexity.
3Temperature
If the panel member is made from heat resistant material, then heat resistance is improved, but the material selection and manufacturing complexity increases
Solution Approach 1:
The use of composite materials with an inner heat-resistant layer and an outer durable fabric layer provides effective heat resistance while allowing manufacturing through standard lamination or coating processes. This approach maintains manufacturing simplicity by using established industrial techniques rather than requiring specialized heat-resistant material processing.
Solution Approach 2:
The patent specifies that the heat-resistant material should have a heat deflection temperature of at least 150°C, providing a clear quantitative parameter for material selection. This parameter-based approach simplifies manufacturing by giving manufacturers specific criteria to meet rather than requiring complex material characterization, thus improving heat resistance while maintaining ease of manufacture.
4Object-affected harmful factors
If the panel member wraps around the basket to block wind, then wind blocking effectiveness is improved, but the fit and alignment precision requirements increase
Solution Approach 1:
The flexible panel members can be bent and shaped to conform to the cylindrical or rectangular form of the chafing dish basket. This flexibility compensates for minor variations in basket dimensions and alignment, allowing effective wind blocking without requiring high-precision manufacturing tolerances for panel fitment and alignment.
Solution Approach 2:
The protective cover is designed to be adjustable and adaptable to different chafing dish configurations. The panels can be positioned and secured at optimal locations to block wind effectively, rather than requiring fixed precision alignment. This dynamic adaptability improves wind blocking effectiveness while reducing manufacturing precision requirements.

AI summary
A protective cover member is a four-walled shield which would serve as a wind blocker, preventing gusts of wind from extinguishing Sternos heaters which are heating a chafing dish. At the same time, the protective cover member would keep the Sterno flames contained within the unit, reducing the risk of fire while also allowing for more effective food warming. In addition, convenient handles would permit users to attend to the Sternos without fear of burning their hands.
