Toroidal Air Aperture Layout for Uniform Autonomous Cooking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing autonomous cooking apparatuses fail to distribute heat uniformly within the cooking compartment, leading to uneven cooking and inefficient energy use due to localized air flow distribution.
Innovation Solution
A hollow toroidal shaped sending aperture on the lid, which cooperates with the peripheral edge of the container, allows for a uniform distribution of heated air across the entire periphery, ensuring all food is cooked evenly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a localized sending aperture is used to send heated air, then the structure is simple, but the heat distribution becomes non-uniform
Solution Approach 1:
The sending aperture is divided into multiple independent nozzles arranged along an arc, where each nozzle directs heated air to a different zone of the container. This segmentation allows the system to maintain structural simplicity while achieving uniform heat distribution across the entire container volume.
Solution Approach 2:
The sending aperture transitions from a single-point localized structure to an arc-shaped distributed structure, adding spatial dimensionality to the air delivery system. This arc arrangement enables heated air to be delivered along a curved path, covering a broader area and improving heat distribution uniformity without significantly increasing structural complexity.
2Device complexity
If heated air is directed to a single localized point, then the device structure is simple, but cooking becomes non-uniform
Solution Approach 1:
The air delivery system is segmented into multiple nozzles positioned at different locations along an arc, with each nozzle targeting a specific cooking zone. This ensures that all areas of the food container receive adequate heated air, achieving uniform cooking results while keeping the overall device structure relatively simple.
Solution Approach 2:
Different sections of the arc-shaped sending aperture are configured to deliver heated air to specific local zones of the container, with each section optimized for its designated area. This local quality approach ensures that every part of the cooking compartment receives appropriate heat treatment, improving cooking uniformity without requiring a completely complex device structure.
3Device complexity
If air flow is concentrated in a restricted zone, then energy consumption is high due to inefficiency, but the sending aperture structure remains simple
Solution Approach 1:
The sending aperture is segmented into multiple nozzles distributed along an arc, allowing heated air to be delivered to multiple zones simultaneously. This reduces energy waste by ensuring that heated air reaches the entire container volume effectively, improving energy efficiency while maintaining a relatively simple aperture structure.
Solution Approach 2:
The sending aperture adopts an arc-shaped configuration that extends in the spatial dimension, allowing heated air to be distributed along a curved path rather than concentrated at a single point. This dimensional expansion improves energy utilization efficiency by ensuring comprehensive heat coverage throughout the container.
