Solution Overview

Problem

Existing cooking devices fail to securely position the transformer on the collector pipe, leading to unintentional movement and instability.

Innovation Solution

A support piece with a connection end, body, and tightening part is designed to securely attach to the transformer, featuring a socket-compatible connection end, a body extending to the jaw, and a tightening part that applies pressure to the pipe surface, preventing movement.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If the transformer is connected to the collector pipe using a simple holder with jaws, then the device complexity is reduced, but the transformer cannot be securely positioned and unintentional movement occurs

Engineering Contradiction:
Improveholder structureVSAvoidtransformer position stability
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The support piece is divided into distinct functional segments: a connection end for socket attachment, a body extending toward the jaw, and a tightening part that contacts the pipe. This segmentation allows each part to perform its specific function optimally while maintaining overall structural integrity and secure positioning.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The support piece acts as an intermediary component between the transformer and the collector pipe. It provides a reliable mechanical connection by engaging with both the transformer's socket and the pipe surface, thereby ensuring stable positioning without requiring direct transformer-to-pipe attachment.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If the transformer is positioned using welding connection to the cooktop plate, then the position stability is improved, but the ease of manufacture and assembly is reduced

Engineering Contradiction:
Improvetransformer position stabilityVSAvoidassembly process
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The invention replaces the welding mechanical system with a mechanical fastening system using the support piece. Instead of permanently attaching the transformer via welding, the support piece provides a reversible mechanical connection through the socket-jaw-tightening mechanism, simplifying assembly and disassembly processes.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The support piece design allows the transformer to be self-positioned and self-secured on the collector pipe. The tightening part automatically applies pressure to the pipe surface when installed, creating a secure connection without requiring additional fastening operations or complex assembly procedures.

Inventive Principle:
Principle #25Self-service

3Ease of operation

If the holder is designed to grab the collector pipe with jaws, then the positioning capability is improved, but the transformer cannot substantially grab the pipe and movement cannot be prevented

Engineering Contradiction:
Improvepositioning capabilityVSAvoidmovement prevention
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The support piece applies local quality by concentrating the tightening function at the tightening part that directly contacts the pipe surface. This localized pressure application ensures secure gripping of the pipe without requiring the entire holder structure to have gripping capability, thereby preventing transformer movement effectively.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The support piece is pre-configured with the tightening part extending to the pipe surface before installation. This preliminary arrangement ensures that when the support piece is installed, the tightening part is already positioned to apply pressure to the pipe, preventing any potential movement of the transformer from the outset.

Inventive Principle:
Principle #10Preliminary action

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

The support piece effectively secures the transformer in place, preventing unintentional movement and ensuring stable operation while also providing grounding and electrical discharge.

Implementation Method 1

a tightening part which extends to the inner surface of the jaw at the continuation of the body and which applies pressure force to the pipe surface whereto the transformer is connected
