Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing induction heating devices have complex structures with multiple components, leading to increased material costs, assembly difficulties, and inefficiencies due to the separation of light emitting and light guide components, which complicates the manufacturing process and requires more personnel for assembly.
Innovation Solution
The induction heating device features a simplified structure with light emitting elements arranged on four surfaces around working coils, using a single indicator substrate that covers the entire coil area, reducing unnecessary components and improving assembly efficiency by minimizing the number of screws required for fixation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If light emitting components and light guide components are separated into different substrates, then the indicator can be assembled flexibly, but the number of components and harness increases, leading to increased material costs and assembly complexity
Solution Approach 1:
The patent combines light emitting components and light guide components into a single integrated indicator substrate. The light emitting element is directly mounted on the indicator substrate, which also serves as the light guide, eliminating the need for separate light guide components and harness connections. This integration reduces the total number of components while maintaining assembly flexibility.
2Manufacturing precision
If an individual indicator substrate is used per working coil, then the indicator can be precisely positioned, but the number of components and harness increases, increasing material costs and assembly complexity
Solution Approach 1:
The patent employs a universal indicator substrate design that can serve multiple working coils simultaneously. The single substrate integrates multiple light emitting elements positioned to correspond with different working coil regions, allowing one substrate to perform the function of multiple individual substrates. This reduces the total number of substrates and harness connections while maintaining precise positioning through proper element arrangement.
3Reliability
If multiple components are required for the indicator, then the indicator function can be achieved, but the assembly process requires more personnel and time, reducing productivity
Solution Approach 1:
The patent merges multiple indicator components into a single integrated assembly. The indicator substrate incorporates both the light emitting element and the light guide function, along with necessary mounting structures and electrical connections. This single integrated component can be installed as one unit, dramatically reducing assembly time and personnel requirements compared to assembling multiple separate components.
4Area of stationary object
If light emitting elements are arranged on all outer portions of the indicator substrate, then complete coverage is achieved, but unnecessary light emitting elements increase material costs
Solution Approach 1:
The patent applies local quality by strategically positioning light emitting elements only in regions where they are functionally necessary. Rather than uniformly distributing elements across the entire indicator substrate, the design places elements specifically at locations corresponding to working coil regions that require indication. This optimized arrangement achieves complete functional coverage while minimizing the total number of light emitting elements required.

Implementation Method 1
a light emitting element disposed vertically below the light guide, and configured to emit light
Implementation Method 2
In the induction heating method, eddy current may be generated in the object made of metal based on a magnetic field generated around the coil based on a high-frequency power having a predetermined magnitude applied to the coil to heat the object

AI summary
An induction heating device includes: a case; working coils; a base plate that supports the working coils; light guides that are installed on the base plate and that cover outer portions of each working coil; light emitting elements disposed below the light guides and configured to emit light; and an indicator substrate that is disposed below the base plate and that seats the light emitting elements. The indicator substrate includes a first indicator substrate, where a first portion of the light emitting elements are arranged along outer portions of the first indicator substrate, and a second indicator substrate disposed at a rear side of the first indicator substrate, where a second portion of the light emitting elements are arranged along outer portions of the second indicator substrate except for an outer portion at a front side that is adjacent to and faces the rear side of the first indicator substrate.
