Split-Lid Grill Design to Prevent Direct Heat Exposure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional grill designs direct hot air towards the user's face when the lid is opened, posing discomfort and safety risks, and require users to frequently open the lid to manage charcoal and food, which can be inconvenient.
Innovation Solution
A split-lid configuration that opens sideways, allowing heat to rise upwards and incorporating drawer-style trays for easy access to charcoal and food, along with viewing windows for monitoring cooking progress without opening the lid.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a traditional front-to-back opening lid is used, then the lid structure is simple and easy to manufacture, but hot air directly hits the user's face causing discomfort and safety risks
Solution Approach 1:
The lid is divided into two separate sections that open independently from the front, allowing each section to be opened partially rather than requiring the entire lid to be opened. This segmentation enables users to access only the necessary portion of the grill while keeping the other section closed, thereby blocking direct heat exposure to the face while maintaining structural simplicity
Solution Approach 2:
The lid sections open horizontally from the front rather than lifting vertically from the back. This dimensional change in the opening direction allows heat to rise upward inside the closed sections while blocking the direct path of hot air toward the user's face, solving the safety issue without significantly increasing structural complexity
2Ease of operation
If the lid is opened frequently to manage charcoal and food, then the user can monitor and adjust cooking elements, but heat continuously escapes and exposes the user to hot air
Solution Approach 1:
The grill interior is divided into multiple accessible sections with independent lid segments. Users can open only the specific section containing the charcoal or food that needs attention, rather than opening the entire lid. This selective access reduces the frequency and extent of heat exposure while maintaining ease of operation for managing cooking elements
Solution Approach 2:
The partially open lid sections act as intermediaries that allow selective access to different grill zones. By positioning the lid sections to open only the necessary portions, users can interact with charcoal and food through controlled openings that minimize heat escape and direct heat exposure compared to opening the full lid
3Ease of operation
If the entire lid is opened to access charcoal and food, then the user has full access to all grill elements, but a large amount of heat escapes and creates safety hazards
Solution Approach 1:
The lid is segmented into multiple independent sections that can be opened individually. Users can open only the specific section containing the element that needs attention (charcoal, food, or monitoring), keeping other sections closed to retain heat. This selective opening minimizes heat loss while providing adequate access to grill elements
Solution Approach 2:
Instead of opening the entire lid (excessive action), users open only the necessary portion of the lid (partial action) required to access or monitor specific grill elements. This partial opening provides sufficient access for most cooking tasks while significantly reducing the amount of heat that escapes, thereby reducing energy loss

AI summary
A grill with a split lid that allows the user to safely and efficiently manage cooking food items. The grill includes a housing body, a first split lid, a second split lid, a grill tray, a charcoal tray, and a support-structure assembly. The first split lid and the second split lid cover and provide access to the housing body. The split lid and the second split lid are positioned opposite to each other, across a main opening of the housing body. The first split lid is laterally and hingedly connected to a first lateral sidewall of the housing body. Similarly, the second split lid is laterally and hingedly connected to a second lateral sidewall of the housing body. The support-structure assembly is adjacently mounted to the housing body, opposite the main opening. The grill tray and the charcoal tray are each laterally and slidably mounted into the housing body.
