Solution Overview
Problem
Graphite's brittle nature and low magnetic flux density make it difficult to apply as a large-area object for induction heating, and small-area graphite is challenging to detect, leading to issues with induction heating cookers stopping prematurely.
Innovation Solution
A graphite structure comprising multiple graphite blocks connected by conductor links, which increases the magnetic flux density and allows for flexible arrangement on surfaces, including curved ones, enabling the graphite to be used as a main or auxiliary heating object.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If small-area graphite is used, then the graphite structure can be applied and handled easily, but the magnetic flux density becomes low making it difficult to detect and use for induction heating
Solution Approach 1:
Multiple small graphite blocks are connected through conductor links to form an integrated graphite structure. This merging approach maintains the ease of handling individual small blocks while achieving high magnetic flux density through the combined structure, enabling successful induction heating detection and operation
2Measurement precision
If large-area graphite is used, then the magnetic flux density is high, but the brittle property of graphite makes it difficult to apply and handle
Solution Approach 1:
The graphite structure is divided into multiple small graphite blocks connected by conductor links. This segmentation allows each block to be small enough for easy handling and application, while the connected structure achieves the magnetic flux density of a large graphite block for successful induction heating
3Adaptability or versatility
If small graphite blocks are used, then the structure can be arranged flexibly on various surfaces, but the magnetic flux density is insufficient for induction heating detection
Solution Approach 1:
Multiple small graphite blocks are connected through conductor links to form an integrated structure. This merging maintains the arrangement flexibility of small blocks on various surfaces while achieving the magnetic flux density required for induction heating detection and operation
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
The connected graphite blocks achieve a magnetic flux density similar to a large block, enhancing heating efficiency and flexibility, allowing small blocks to be effectively heated and arranged on various surfaces without premature cooker shutdown.
Implementation Method 1
the graphite has a brittle property (graphite can be brittle), making it difficult to apply large-area graphite, and small-area graphite does not have a high magnetic flux density, making it difficult to select an object to be heated for induction heating
Implementation Method 2
graphite is light in weight and has a high electrical conductivity that is greater than the electrical conductivity of stainless steel, which is used as an object to be heated during induction heating
