Rotating structure and container using rotating structure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Microwave ovens often cause local overheating and irregular heating due to the concentric rotation of turntables or stirrers, which fail to evenly distribute heat in three-dimensional objects or objects with cylindrical or cone shapes, leading to inefficient cooking.
Innovation Solution
A rotating structure where a pouch containing a sublimable or evaporable raw material is wound around a container, expanding as it heats and causing the container to rotate, allowing for uniform heating by adjusting the expansion time and direction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a turntable or stirrer rotates concentrically based on a vertical shaft, then the device structure is simple and easy to manufacture, but local overheating and non-heating phenomena occur in upward and downward directions
Solution Approach 1:
The patent applies asymmetry by using an eccentric rotation mechanism where the container rotates around an axis that does not pass through its center of gravity. This creates asymmetric motion patterns that prevent stagnant heating zones and improve temperature uniformity throughout the heating body, resolving the local overheating issue while maintaining manufacturing simplicity
Solution Approach 2:
The patent introduces a new dimension of motion by combining vertical displacement with horizontal rotation. The container not only rotates but also moves up and down in an eccentric pattern, adding a vertical dimension to the traditionally horizontal rotation. This multi-dimensional motion effectively distributes heat throughout the entire heating body, eliminating the upward and downward heating不均匀问题
2Device complexity
If a turntable rotates based on the rotation center, then the rotation mechanism is simple, but heating occurs in a concentric shape causing irregular heating according to distance from the rotation center
Solution Approach 1:
The patent employs asymmetry through eccentric rotation where the container's center of gravity is offset from the rotation axis. This creates an asymmetric orbital motion pattern that ensures all regions of the heating body, regardless of their distance from the center, receive equivalent heating exposure over one complete cycle, eliminating concentric heating patterns
Solution Approach 2:
The patent transforms the static concentric rotation into a dynamic eccentric orbital motion. The container follows an elliptical path rather than a circular path centered on the rotation axis. This dynamic motion pattern continuously changes the distance and orientation of different heating body regions relative to the heat source, achieving uniform heating without increasing device complexity
3Shape
If the heating body is relatively thick in a specific direction, then the product has three-dimensional structure, but local overheating and non-heating phenomena occur inside the thick portion
Solution Approach 1:
The patent addresses three-dimensional heating challenges by introducing vertical motion to the traditional horizontal rotation. The eccentric mechanism causes the container to oscillate vertically while rotating, ensuring that thick portions of the heating body are exposed to heat from multiple angles and positions, eliminating internal overheating and cold spots
Solution Approach 2:
The patent uses dynamic eccentric motion to continuously vary the positioning of thick product portions relative to the heat source. Instead of static rotation that may leave thick sections in stagnant zones, the dynamic orbital motion ensures continuous movement through different thermal fields, achieving uniform heating throughout the three-dimensional product structure
4Shape
If the heating body has a cylindrical shape or cone shape, then the product has regular geometry, but local overheating and non-heating phenomena occur due to concentric rotation
Solution Approach 1:
The patent applies asymmetry through eccentric rotation that disrupts the symmetric heating pattern inherent in concentric rotation. For cylindrical or conical products, this asymmetric motion ensures that all surface areas and internal regions receive equivalent thermal exposure over time, eliminating the local overheating and non-heating phenomena that occur with symmetric rotation
