Solution Overview

Problem

Household waffle irons often face issues with users losing or misplacing cooking plates when they are separated from the appliance, especially when the original packaging is destroyed or when the device is used far from its storage place.

Innovation Solution

Incorporating a dedicated cavity within the appliance for storing the cooking plates, ensuring they remain attached and easily accessible, with a locking mechanism and a latching system to secure the plates in place.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If the cooking plates are separated from the appliance for cleaning or storage, then the appliance can be cleaned more easily and the plates can be used for different cooking functions, but the plates can be lost or misplaced by users

Engineering Contradiction:
Improveease of cleaningVSAvoidplate retention
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The cavity integrated into the appliance housing provides a nested storage space for the cooking plates. When plates are not in use, they are stored within the cavity, ensuring they remain associated with the appliance and cannot be lost or misplaced, while still allowing easy removal for cleaning.

Inventive Principle:
Principle #7Nested doll (Nesting)

2Reliability

If a cavity is added to store the cooking plates, then the plates cannot be lost or misplaced, but the device complexity increases

Engineering Contradiction:
Improveplate retentionVSAvoidappliance structure
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The cavity is integrated directly into the existing appliance housing structure, merging the storage function with the existing body of the appliance. This approach adds the storage capability without requiring a separate, independent storage component, thereby minimizing the increase in overall device complexity.

Inventive Principle:
Principle #5Merging (Combining)

3Ease of operation

If the cavity is made accessible from the front face, then the plates can be easily stored and retrieved, but the structural integrity of the appliance may be compromised

Engineering Contradiction:
Improveplate accessibilityVSAvoidappliance structure
Core Design Contradiction:
Ease of operationVSStrength

Solution Approach 1:

The opening is positioned in the front face of the housing, providing easy access to the cavity. The housing structure is designed with localized reinforcement around the opening to maintain structural integrity while allowing access. This ensures that the opening does not compromise the overall strength of the appliance.

Inventive Principle:
Principle #3Local quality

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

This solution keeps the appliance complete and ready for use by preventing plate separation, facilitating storage, and reducing the risk of loss or misplacement, while maintaining ease of use and cleaning.

Implementation Method 1

an electric heating resistance making it possible to supply the cooking plate 7 with the energy necessary for cooking the food. The electric heating resistance is arranged in the shell 6, under the cooking plate 7, and, in the present embodiment, it is in contact with the cooking plate 7, the transmission of energy taking place by conduction.

Methodology Applied
Scientific EffectThermal conduction: Conduction (thermal)

Implementation Method 2

each cooking sub-assembly 2, 3 comprises a thermal reflector which is arranged between the electrical resistance and the shell 6 so as to protect the latter from the heat given off by the former.

Methodology Applied
Scientific EffectThermal radiation reflection: Reflection

AI summary

The appliance (1) has lower and upper cooking subsets (2,3) articulated between an open position and a close position. Each of the cooking subset has a lower hull (6) forming body of the subsets and a removable cooking plate (7) receiving food such as meat, to be cooked. A cavity (11) is provided for arranging the cooking plate. The cavity has an opening that permits the passage of the plate and is accessible from exterior of the appliance regardless of relative position of the subsets.
