Solution Overview

Problem

Conventional induction heating devices face challenges in efficiently and cost-effectively connecting the induction coil to the carrier plate, leading to increased production time and costs due to the use of screws.

Innovation Solution

The induction coil is connected to the carrier plate using a first and second connection member with vertical and horizontal portions, which are inserted into corresponding slots on the base plate, allowing for a secure and efficient assembly process.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If screws are used to connect the induction coil to the carrier plate, then the connection is reliable, but the production time increases and production costs increase

Engineering Contradiction:
Improveconnection reliabilityVSAvoidproduction time
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The connection system is segmented into separate components: connection members with vertical portions extending from the carrier plate, and slots in the base plate that accommodate these vertical portions. This segmentation allows for easier assembly compared to traditional screw connections while maintaining structural integrity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Connection members act as intermediary elements between the carrier plate and the base plate of the induction coil. These intermediaries facilitate the connection process by providing a simple insertion mechanism through the slots, eliminating the need for complex screw fastening while ensuring reliable mechanical coupling.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If screws are used to connect the induction coil to the carrier plate, then the connection is reliable, but the production costs increase

Engineering Contradiction:
Improveconnection reliabilityVSAvoidproduction cost
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The connection system is divided into modular components (connection members and slots) that can be manufactured separately and assembled easily. This segmentation reduces manufacturing complexity and costs compared to precision-machined screw holes and fasteners, while maintaining connection reliability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The connection members appear to be simple, inexpensive components that can be easily manufactured and replaced if needed. This approach uses cost-effective elements rather than expensive screw fastening systems, reducing overall production costs while maintaining functional reliability.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

3Productivity

If a simple connection method is used to reduce production time, then productivity improves, but the connection reliability may be compromised

Engineering Contradiction:
Improveproduction timeVSAvoidconnection reliability
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

By segmenting the connection into vertical portions and corresponding slots, the design achieves both simplicity for fast assembly and reliability through precise geometric fitting. The segmented structure allows quick insertion while maintaining secure mechanical connection.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The vertical portions of the connection members are nested within the slots of the base plate, creating a secure fitted connection. This nesting arrangement ensures reliable mechanical coupling while allowing for rapid assembly without complex fastening operations.

Inventive Principle:
Principle #7Nested doll (Nesting)
