Solution Overview

Problem

Cooking apparatuses face challenges in protecting control panels from heat generated within the cooking cavity and effectively guiding air flow for cooling, particularly when the control panel is located on the door, which can hinder the expansion of the cooking cavity's height and width.

Innovation Solution

A bracket is integrated into the door to shield the control panel from heat and guide air flow, blocking heat transfer while allowing the air to flow through, thus protecting the panel and enhancing cooling efficiency.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Volume of moving object

If the control panel is located on the door, then the cooking cavity height and width can be expanded, but the control panel is exposed to heat from the cooking cavity

Engineering Contradiction:
Improvecooking cavity volumeVSAvoidheat exposure to control panel
Core Design Contradiction:
Volume of moving objectVSObject-affected harmful factors

Solution Approach 1:

The door structure is segmented into multiple components: the door body, a heat shielding bracket, and the control panel. The bracket is positioned between the cooking cavity and the control panel to create a thermal barrier, separating the heat source from the sensitive control components while maintaining the door's structural integrity and functionality.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

A heat shielding bracket is introduced as an intermediary element between the cooking cavity (heat source) and the control panel (sensitive component). This bracket acts as a thermal mediator that blocks heat transfer to the control panel while allowing the door to remain open and functional.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Object-affected harmful factors

If heat shielding is added to protect the control panel, then heat protection is improved, but the device structure becomes more complex

Engineering Contradiction:
Improveheat protection of control panelVSAvoiddoor structure complexity
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The heat shielding bracket is merged with the door assembly rather than being a separate, standalone component. The bracket is integrated into the door's structural framework, combining the heat shielding function with the existing door support and mounting structures, thereby reducing overall complexity.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The bracket serves multiple functions: it provides heat shielding for the control panel, acts as a structural support element for the door, and potentially serves as a mounting fixture for other door components. This multi-functionality reduces the need for additional separate parts.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Object-affected harmful factors

If the bracket blocks heat transfer to the control panel, then heat protection is improved, but air flow for cooling may be obstructed

Engineering Contradiction:
Improveheat protection of control panelVSAvoidcooling air flow efficiency
Core Design Contradiction:
Object-affected harmful factorsVSLoss of energy

Solution Approach 1:

The bracket is designed with non-uniform geometry featuring open regions and solid regions. The solid portions provide heat blocking where needed, while the open regions allow cooling air to pass through. This local differentiation of properties (open vs. solid) enables simultaneous heat protection and air flow maintenance.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The bracket incorporates thin wall structures that provide thermal blocking while maintaining airflow permeability. The thin film-like portions of the bracket are sufficient to block radiant and conductive heat transfer but do not significantly impede convective air flow for cooling purposes.

Inventive Principle:
Principle #30Flexible shells and thin films
