Oven
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional ovens require users to manually remove baked goods to add additional ingredients, risking burns from the oven's inner walls due to the inability of the oven door to support or hold items during this process.
Innovation Solution
The oven design includes a pivotally connected door that forms a platform outside the entrance when open, with a frame-abutted portion increasing the door's bearing capacity, allowing safe placement and transfer of baked objects without direct contact with the oven's inner walls.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the conventional oven door is used without support structure, then the structure is simple, but the door cannot support baked goods when open, requiring manual handling that risks burns
Solution Approach 1:
The frame is divided into multiple components including side pieces and a crosspiece that can be assembled together to form the support structure. The oven door is segmented with a platform portion and a handle portion, allowing independent functionality of each segment.
Solution Approach 2:
The frame provides more support than minimally required by extending the platform beyond the door opening, creating an oversized support surface that can accommodate various baking pans and trays, exceeding the basic functional requirement.
2Strength
If the oven door is modified to include a platform and frame support, then the bearing ability is increased to support baked goods, but the device complexity increases
Solution Approach 1:
The frame structure is merged with the oven door assembly, where the side pieces and crosspiece form an integrated support system with the door. The platform is merged with the door, creating a combined structure that serves both as a door and a support surface.
Solution Approach 2:
The frame and platform structure serves multiple functions simultaneously: it supports the oven door, provides a platform for baked goods, and creates an oversized support surface. The structure is designed to be self-supporting, eliminating the need for additional external support mechanisms.
3Adaptability or versatility
If users manually remove baked goods from the oven to add ingredients, then ingredients can be added, but users risk burns from touching the hot inner walls
Solution Approach 1:
The platform acts as an intermediary between the oven interior and the user's hands. Baked goods are placed on the platform, which is supported by the frame, allowing users to add ingredients without directly touching the hot oven walls or the baked goods themselves.
Solution Approach 2:
The solution moves the support function from the vertical dimension (reaching into the oven) to the horizontal dimension (platform extending outward). By creating an oversized support surface that extends beyond the door opening, the system allows ingredient addition from a safe external position rather than from within the hot oven space.
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 design enables users to add ingredients safely without risking burns, as the oven door can support objects externally, facilitating easier handling and reducing the risk of scalding from the oven's inner walls.
Implementation Method 1
The heating element is disposed in the oven body and is adapted to heat the inner space
Implementation Method 2
The heating element is disposed in the oven body and is adapted to heat the inner space
Implementation Method 3
The oven door is pivotally connected to the oven body and is located at the entrance. When the oven door pivots to a closed position, the entrance is closed. When the oven door pivots down to an open position from the closed position, the entrance is opened.
Implementation Method 4
When the oven door is located at the open position, the second surface of the oven door is abutted against the abutted portion of the frame. Since the abutted portion of the frame abuts the second surface of the oven door, the bearing ability of the oven door could be increased

AI summary
An oven includes an oven body, a heating element, a frame, and an oven door. The oven body has an inner space inside and includes a front plate, wherein the front plate has an entrance that communicates with the inner space. The heating element is adapted to heat the inner space. The frame is engaged with the oven body and has an abutted portion. The oven door is pivotally connected to the oven body and is located at the entrance. The oven door can pivot to a closed position to close the entrance and can pivot downward to an open position from the closed position to open the entrance. When the oven door is located at the open position, the second surface abuts against the abutted portion of the frame, thereby forming a platform outside the entrance for placing objects.
