Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing induction cooking devices face challenges in achieving a firm mechanical and electrical connection between the induction heating element and the carrier element, which complicates assembly and maintenance, and can result in inefficient operation due to long wire lengths.
Innovation Solution
The connection means include a reception element with undercuts and a connection member with resilient protrusions that snap into place, forming a secure snap-connection for easy assembly and disassembly, ensuring both mechanical and electrical coupling, and utilizing a short wire connection to improve high-frequency decoupling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional connection methods are used to connect the heating element to the carrier element, then a firm mechanical and electrical connection is achieved, but the assembly process becomes complex and time-consuming
Solution Approach 1:
The connection system is divided into separate functional elements: the spring element with integrated electrical contact and the recess with undercut in the carrier element. This segmentation allows each component to be optimized independently while simplifying the overall assembly process through modular installation.
Solution Approach 2:
The spring element and electrical contact are merged into a single integrated component. The spring element serves both mechanical functions (providing contact pressure and electrical isolation) and electrical functions (conducting current) simultaneously, reducing the number of parts and simplifying assembly.
2Reliability
If traditional connection methods are used, then electrical connection is established, but maintenance and servicing become difficult
Solution Approach 1:
The heating element and carrier element are segmented as separate, easily replaceable modules. The spring element connection allows the heating element to be quickly detached and replaced without complex disassembly procedures, facilitating maintenance and servicing.
3Ease of operation
If long wire lengths are used for electrical connection, then connection flexibility is improved, but high-frequency operation efficiency decreases
Solution Approach 1:
The spring element acts as an intermediary component that provides both mechanical compliance and electrical conduction in a compact form. It enables reliable electrical connection with minimal wire length by serving as the primary electrical pathway between the heating element and carrier element.

AI summary
A cooking device having an electrical heating element is arranged on a carrier element. At least one electrical wire is connected with the carrier element. The connection is facilitated by a reception element having two recesses forming undercuts and a connection member with a basis structure and an electrical contact for engagement with the wire. The connection member has two protrusions extending from the basis structure of the connection member and can be inserted into the recesses.
