Solution Overview

Problem

Conventional clamshell grills have limited compression force for cooking due to the weight of the upper platen assembly and suffer from reliability issues with leveling components exposed to high temperatures, affecting cooking efficiency and food handling.

Innovation Solution

A grill design featuring a movable lower grill plate with leveling mechanisms and a latch mechanism to enhance compression force and stability, allowing for adjustable gap settings and improved heat distribution, along with integrated grease receptacles for efficient food handling and cleaning.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Force

If the upper platen assembly is used to apply compression force to the food, then the food can be grilled effectively, but the compression force is limited to the weight of the platen

Engineering Contradiction:
Improvecompression forceVSAvoidweight of upper platen assembly
Core Design Contradiction:
ForceVSWeight of moving object

Solution Approach 1:

The patent inverts the traditional clamshell grill design by making the lower platen assembly movable instead of the upper platen assembly. This allows the lower platen to be raised and lowered to apply compression force to the food, while the upper platen remains stationary and can be securely latched in place. The movable lower platen can be equipped with leveling mechanisms that are not exposed to high temperatures, and the stationary upper platen can be heavier to provide adequate compression force without movement limitations.

Inventive Principle:
Principle #13The other way round (Inversion)

2Manufacturing precision

If leveling components are positioned above the upper platen assembly, then the upper platen can be leveled, but the excessive heat affects the reliability and operation of the leveling component

Engineering Contradiction:
Improveleveling precisionVSAvoidreliability of leveling component
Core Design Contradiction:
Manufacturing precisionVSReliability

Solution Approach 1:

The patent extracts the leveling mechanisms from the high-temperature upper platen assembly and relocates them to the lower platen assembly. The lower platen, being movable and positioned away from the primary heat source, provides a cooler environment for the leveling components. This extraction allows the leveling mechanisms to operate reliably without being exposed to excessive heat, while still achieving the necessary leveling precision for proper grilling.

Inventive Principle:
Principle #2Taking out (Extraction)

3Force

If the upper platen assembly is made heavier to increase compression force, then better food searing can be achieved, but the device complexity and operator effort increase

Engineering Contradiction:
Improvecompression forceVSAvoidcomplexity of platen assembly
Core Design Contradiction:
ForceVSDevice complexity

Solution Approach 1:

By inverting which platen is movable, the patent allows the stationary upper platen to be optimized for weight and compression force without compromising operational ease. The heavier upper platen can be securely latched in place, providing adequate compression force for food searing. The movable lower platen, being lighter and equipped with leveling mechanisms, is easier to operate and position, reducing overall device complexity and operator effort.

Inventive Principle:
Principle #13The other way round (Inversion)

AI summary

A grill is provided including a base structure. An upper platen assembly is connected to the base structure and includes an upper gritting plate. A lower platen assembly is connected to the base structure and includes a lower grilling plate. A plurality of leveling mechanisms is mounted to the base structure and arranged in contact with the lower grilling plate. The leveling mechanisms are configured to move the lower gritting plate relative to the upper grilling plate. At least one grease receptacle has an inboard sidewall and an outboard sidewall connected by a compartment configured to receive grease from a grilling surface of the lower plate. The inboard sidewall is mounted to the lower grilling plate at or below the grilling surface.
