Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cooking appliances with built-in niches face challenges in achieving a significant temperature drop between the cooking appliance and adjacent furniture without compromising the volume of the cooking space, often requiring additional installation space and expensive thermal insulation.
Innovation Solution
The cooking appliance features a housing with outer walls that include indentations and embossing areas specifically designed to surround the muffle, creating a compact shape that enhances temperature drop by varying the distance between the muffle and furniture walls, and incorporates a thermally shielding plate element for efficient cooling, promoting air circulation and turbulence.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If appropriate thermal insulation around the cooking chamber is provided, then the temperature drop between cooking appliance and furniture is improved, but additional installation space is required and cooking space volume is reduced
Solution Approach 1:
The outer wall is provided with localized indentations and embossing areas at specific positions adjacent to the muffle, creating zone-specific thermal management. The embossing areas with increased surface area are positioned precisely where thermal insulation is most needed, while other areas maintain their original configuration to preserve cooking space volume.
Solution Approach 2:
The solution transitions from a uniform thermal insulation approach to a multi-dimensional configuration by adding indentations and embossing features to the outer wall. This creates varying distances between the muffle and outer wall at different locations, effectively adding geometric complexity in the spatial dimension to achieve thermal management without uniform space consumption.
2Temperature
If a relatively large distance between the cooking space and built-in furniture is maintained, then temperature drop is improved, but cooking space volume is reduced
Solution Approach 1:
Instead of uniformly increasing the distance between cooking space and furniture, the invention applies localized indentations and embossing features only in specific zones where thermal management is critical. This maintains the original cooking space volume while achieving temperature drop through targeted geometric modifications to the outer wall configuration.
3Temperature
If specific heat-insulating materials are used, then temperature drop is improved, but cost increases significantly
Solution Approach 1:
The invention changes the geometric parameters of the outer wall by introducing indentations and embossing features, rather than changing the material parameters by using expensive heat-insulating materials. This modifies the thermal management approach from material-based to geometry-based, achieving temperature drop through increased surface area and altered heat transfer paths without incurring significant material costs.
4Volume of stationary object
If outer wall is made compact to reduce installation space, then installation space requirement is reduced, but temperature management becomes more difficult
Solution Approach 1:
The outer wall is designed with local variations in configuration through indentations and embossing areas at specific positions. These localized features create zones with different thermal characteristics, allowing effective temperature management in critical areas while maintaining an overall compact form factor for reduced installation space requirements.
Solution Approach 2:
The solution resolves the contradiction by introducing geometric complexity in the form of indentations and embossing features on the outer wall surface. This adds dimensional variation to the compact structure, creating effective thermal management zones without significantly increasing the overall installation space footprint.
5Ease of manufacture
If thin sheet metal housing parts are used, then manufacturing cost is reduced, but torsional rigidity is insufficient
Solution Approach 1:
The indentations and embossing features introduce curved geometric forms to the thin sheet metal outer wall. These curved features, particularly the embossing areas with raised portions, inherently increase the torsional rigidity of the sheet metal structure by creating geometric reinforcement, allowing the use of thinner, more cost-effective materials while maintaining structural strength.
