Induction Coil Assembly Using Power Cables as Spring Elements
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The installation of induction cooking hob components is complex due to the need for precise arrangement and connection of induction coils, temperature sensors, and power supply units, which requires specialized spring elements and multiple steps.
Innovation Solution
A modular induction coil assembly with a carrier plate supporting the coil winding, electrically isolating sheets, and thermally insulating sheets, where power cables act as spring elements to simplify installation by pressing the coil assembly against the glass ceramic panel, eliminating the need for additional spring elements and reducing complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional separate component installation is used, then precise arrangement and connection can be achieved, but installation complexity increases and requires specialized spring elements
Solution Approach 1:
The patent combines the coil winding, temperature sensor, power cables, and carrier plate into a single integrated induction coil assembly. This merging eliminates the need for separate installation of multiple components and removes the requirement for specialized spring elements, as the power cables themselves provide the necessary mechanical support and electrical connection. The assembly can be installed as one unit, significantly reducing installation complexity while maintaining precise arrangement through the integrated design.
2Reliability
If multiple separate components are installed, then functional requirements are met, but installation time and steps increase
Solution Approach 1:
The patent implements preliminary action by pre-assembling the coil winding, temperature sensor, power cables, and carrier plate into a complete induction coil assembly before installation. All functional connections and mechanical arrangements are prepared in advance during manufacturing, allowing the entire assembly to be installed in one step rather than requiring multiple sequential installation steps for individual components. This dramatically reduces installation time while ensuring all functional requirements are met through the pre-configured assembly.
