Induction Coil Snap Connection for Shorter Cooker Wiring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing induction cooking devices face challenges in achieving a firm and efficient electrical and mechanical connection between the heating element and the carrier element, which complicates assembly and maintenance, and can lead to inefficient operation due to long wire lengths.
Innovation Solution
A connection member made of sheet metal with resilient protrusions that form a snap-connection with recesses in the reception element, ensuring a secure and easy assembly and disassembly of the induction coil, utilizing a V-shaped contour for the protrusions and a flat basis structure, and an electrical wrap connection for efficient high-frequency decoupling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional connection methods are used to ensure firm mechanical and electrical connection, then connection reliability is improved, but device complexity and assembly difficulty increase
Solution Approach 1:
The connection means are divided into separate components: a connection member with resilient protrusions and a reception element with recesses. This segmentation allows for simple assembly by snapping the components together while maintaining firm mechanical and electrical connection, resolving the contradiction between connection reliability and assembly complexity.
Solution Approach 2:
The connection member integrates both mechanical connection functions (protrusions for snap-fit) and electrical connection functions (contact for electrical wire) into a single component. This merging eliminates the need for separate mechanical fasteners and electrical connectors, simplifying assembly while ensuring reliable combined mechanical-electrical connection.
2Reliability
If traditional wiring methods are used, then electrical connection is established, but wire length increases reducing operational efficiency
Solution Approach 1:
The electrical connection function is extracted from the traditional long-wire routing and integrated directly into the connection member. The electrical contact on the connection member provides a short, direct electrical path, eliminating the need for long wires and improving operational efficiency while maintaining reliable electrical connection.
3Strength
If complex connection methods are used to ensure firm connection, then connection strength is improved, but manufacturing cost increases
Solution Approach 1:
The connection member uses resilient protrusions made from sheet metal with modified physical parameters (elasticity, shape). The protrusions are designed with specific resilience characteristics that enable strong snap-fit connection while being manufactured from simple sheet metal through punching and bending operations, keeping manufacturing costs low while achieving strong connections.
