Solution Overview

Problem

Induction hobs face challenges in efficient assembly due to inductor placement and cable management, where inductors may cover openings, require long connection cables, and result in complex and error-prone assembly processes.

Innovation Solution

The method involves positioning an opening or recess in the inductor support plate approximately between inductors, allowing for uniform cable lengths and avoiding inductor protrusion, with the option to divide the opening into partial ones for better cable passage, and using connection devices like clamps or plug-in connections for easy access.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If inductors are arranged on the inductor support plate with connections from the support side, then electrical connection can be achieved, but the opening may be covered by inductors requiring expensive specialized assembly

Engineering Contradiction:

Improveelectrical connection reliabilityVSAvoidassembly cost and complexity

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The opening position is predetermined and optimized during the design phase to be centrally located relative to all inductors. This preliminary positioning ensures that standard assembly procedures can be used without requiring expensive specialized assembly processes, while still achieving reliable electrical connections for all inductors.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

A single centrally positioned opening serves as a universal access point for connecting multiple inductors located at different positions on the support plate. This universal opening eliminates the need for separate openings for each inductor, simplifying the manufacturing process and reducing costs.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Ease of operation

If inductors are positioned far from the opening, then connection is easier, but long connection cables are required adding assembly effort and creating nuisances

Engineering Contradiction:

Improveconnection easeVSAvoidassembly time for cable management

Core Design Contradiction:

Ease of operationVSLoss of time

Solution Approach 1:

The opening position is predetermined and optimized during the design phase to achieve an optimal balance between connection ease and cable length. This preliminary optimization ensures that inductors are positioned at distances that allow for manageable cable lengths, reducing assembly time and eliminating cable management nuisances.

Inventive Principle:

Principle #10Preliminary action

AI summary

A construction method of induction hob (11) involves attaching inductors (15a-15c) on a first side of inductor support plate (13) in a respective predetermined position such that a space is defined between inductors. A receptacle (20) for control mechanism (22) and power electronics (24) is attached on a second side of inductor support plate. The respective connecting cable (17a-17c) is passed through the opening in inductor support plate. The respective connecting cable is connected to the control mechanism and power electronics. An independent claim is also included for the induction hob.
