Inductive heating cooker
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional induction-heating cookers face challenges in achieving a smaller and thinner design due to the requirement for a larger, box-shaped operation board holder, which increases development costs and mold/die investments, as the holder must accommodate various operation board shapes and sizes.
Innovation Solution
The induction-heating cooker features an outer frame with an upper opening and a top plate, where the operation board is held from the lower surface side by an operation board holding part on the outer frame side surface, allowing for a reduced space occupation and effective space utilization, with a support member connecting the frame's sides to enhance rigidity and accommodate diverse operation board sizes and shapes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a bottomed box-shaped operation board holder is used to house the operation board, then the operation board is securely fixed to the outer frame, but the holder occupies excessive space and increases the overall size and thickness of the induction-heating cooker
Solution Approach 1:
The invention extracts the operation board holder from the conventional bottomed box-shaped structure and repositions it to the side surface of the outer frame. This removes the holder from the internal space, allowing the operation board to be held securely while opening up the internal volume for better space utilization and thinner design.
Solution Approach 2:
The invention transitions the operation board holder from a three-dimensional box structure occupying internal space to a two-dimensional surface-mounted structure on the side surface of the outer frame. This dimensional change eliminates the need for the holder to occupy vertical space, enabling a thinner overall design.
2Adaptability or versatility
If the operation board holder is designed to accommodate various operation board shapes and sizes, then the holder must be made in multiple variations, but this increases development costs and investment in molds and dies
Solution Approach 1:
The invention designs a universal operation board holder that can accommodate multiple operation board shapes and sizes. The holder is configured with a recessed portion that can adapt to different board dimensions, eliminating the need for multiple specialized holders and reducing development complexity.
Solution Approach 2:
The holder incorporates flexible or adjustable elements that allow it to adapt dynamically to different operation board configurations. This dynamic capability enables a single holder design to serve multiple purposes across different product variations.
3Reliability
If the operation board holder is positioned inside the outer frame, then the operation board is protected and secured, but the internal space is reduced and the cooker cannot achieve a thinner profile
Solution Approach 1:
The invention extracts the operation board holder from the internal positioning and relocates it to the side surface of the outer frame. This extraction removes the holder from the thickness-critical path, allowing the cooker to achieve a thinner profile while maintaining secure operation board mounting.
Solution Approach 2:
The holder design incorporates thin-walled or flexible structures that provide adequate protection and securing functionality with minimal thickness, enabling the overall cooker design to be more compact in the vertical dimension.

AI summary
The outer frame 4 has a plurality of outer frame throughhole 7, an operation board holding member 6 goes through the outer frame throughhole 7 and fixed to the outer frame 4. Thereby, it is possible to hold and fix the operation board 3 to the outer frame side surface 4a with a simple and inexpensive configuration. Accordingly, this makes it possible to reduce the space occupied by the operation board holding member 6 in the main body, and parts can be arranged efficiently within a limited space of the main body, thereby achieving a thinner size of the outer frame 4 in the induction-heating cooker.
