Solution Overview
Problem
Existing coating removal systems using electromagnetic induction heating face challenges in efficiently removing coatings from small parts due to heavy apparatuses and requiring transformer replacement for different heating head sizes, leading to inefficiencies in time and effort.
Innovation Solution
A heater system with a high-frequency power source, transformer, and detachable heating units, where the inductance values of the heating units and cables are adjustable to match the selected heating head, allowing for seamless switching between different heating heads without replacing the transformer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a heavy apparatus body including power source and transformer is moved to reach target area, then the heating unit can be positioned for coating removal, but the apparatus becomes difficult to move and cannot smoothly remove coating from small parts
Solution Approach 1:
The apparatus is divided into a stationary body (10) containing the heavy power source and transformer, and a movable heating unit (20) that can be detached and positioned at the target area. This segmentation allows the heavy components to remain fixed while only the lightweight heating unit needs to be moved, resolving the contradiction between ease of movement and operational capability.
2Adaptability or versatility
If multiple heating heads with different sizes are used for different coating removal areas, then the apparatus can handle various applications, but the transformer must be replaced which requires significant time and effort
Solution Approach 1:
The transformer (21) is designed with universal compatibility to work with multiple heating heads (31, 32) of different sizes through detachable connections. This allows the same transformer to serve multiple functions with different heating heads, eliminating the need for replacement and reducing the time loss when changing between different coating removal applications.
3Ease of operation
If the inductance value of heating units is adjusted to match the selected heating head, then seamless switching between heating heads is enabled, but the system complexity increases
Solution Approach 1:
The inductance values of the heating units are adjusted to correspond to the characteristics of different heating heads. By pre-setting appropriate inductance values for each heating unit configuration, the system enables seamless switching between heating heads of different sizes without requiring complex real-time adjustments, thus improving ease of operation while managing system complexity through pre-configured parameters.
