Oven Door Covering Member for Gap-Free Cleanable Edges
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cooking device doors, especially oven doors, face issues with dirt and liquid accumulation at the upper surface due to gaps between multi-layered insulation, making them difficult to clean and aesthetically unappealing.
Innovation Solution
A door design featuring a covering member with a plate-like body and extending skirts that covers the upper edges of the inner and outer panels, creating a single surface and preventing dirt and liquids from entering the gaps, with optional stainless steel construction and a locking mechanism for easy assembly and disassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If multi-layered door construction is used for heat insulation, then thermal insulation efficiency is improved, but gaps between layers allow liquid and dirt transmission
Solution Approach 1:
A covering member is introduced as an intermediary element between the multi-layered door structure and the external environment. This covering member includes a body that covers the upper surface and skirts that extend downward to cover the gaps between door layers, thereby preventing liquid and dirt from entering the gaps while maintaining the thermal insulation structure.
2Stability of the object's composition
If door layers are joined together, then structural integrity is improved, but gaps at junctures create unfavorable appearance and accumulation of dirt
Solution Approach 1:
The covering member acts as a mediator that conceals the junctures between door layers. The body portion covers the upper surface where layers join, and the skirts extend downward to cover the vertical gaps, thereby hiding the structural joints from view and preventing dirt accumulation at these junctures while preserving structural integrity.
Solution Approach 2:
The covering member is constructed as a thin, flexible plate-like structure with skirts that can conform to the door assembly. This thin film approach allows the covering member to effectively cover the gaps and junctures without adding significant bulk, maintaining aesthetic appearance while preventing dirt accumulation.
3Ease of operation
If covering member is added to cover door edges, then ease of cleaning is improved, but device complexity increases
Solution Approach 1:
The covering member is segmented into distinct functional portions: a body portion that covers the upper surface and skirts that extend downward from the body. This segmentation allows each portion to perform its specific function - the body provides upper surface coverage while the skirts specifically address the gap coverage and cleaning facilitation, thereby achieving ease of cleaning with a relatively simple segmented structure.
