Solution Overview

Problem

Existing wax melting devices face issues such as premature aging of electronic components due to high temperatures, risk of scalding, and poor heat conduction and contact between heating and temperature sensing assemblies, leading to temperature inconsistencies and potential safety hazards.

Innovation Solution

The wax melting device incorporates a spacing bracket to separate the heating aluminum pot from the PTC heating sheet and electronic control circuit board, along with aluminum-pot pressing blocks to secure the pot and improve heat transfer, and a fixing bracket to stabilize the temperature sensing probe and PTC heating sheet for consistent contact and monitoring.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Temperature

If the heating aluminum pot is placed close to the heating element for efficient heat transfer, then heat conduction efficiency is improved, but electronic components are exposed to high temperatures causing premature aging

Engineering Contradiction:

Improveheat conduction efficiencyVSAvoidelectronic component lifespan

Core Design Contradiction:

TemperatureVSReliability

Solution Approach 1:

The device is divided into distinct temperature zones: a heating zone with the PTC heating sheet and aluminum pot, and a control zone with the circuit board separated by the housing structure. This spatial segmentation allows efficient heat transfer in the heating zone while protecting electronic components in the control zone from high temperatures.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The housing structure acts as an intermediary thermal barrier between the heating aluminum pot and the electronic control circuit board. It allows the heating elements to operate at high temperatures for efficient heat conduction while the housing material protects the electronic components from thermal damage.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Stability of the object's composition

If the heating aluminum pot is secured tightly to the heating element for stable contact, then heat transfer stability is improved, but the risk of scalding to users increases

Engineering Contradiction:

Improveheat transfer stabilityVSAvoidscalding risk

Core Design Contradiction:

Stability of the object's compositionVSObject-affected harmful factors

Solution Approach 1:

The PTC heating sheet is extracted from direct contact with the aluminum pot, instead being mounted on the housing structure. This separation maintains stable heat transfer through the housing while preventing the heating element from being exposed where it could cause scalding.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The housing structure serves as an intermediary between the heating element and the external environment, providing thermal isolation that maintains stable heat transfer to the aluminum pot while preventing direct access to the heating element that could cause scalding.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Ease of manufacture

If the temperature sensing probe and heating element are mounted using flexible materials like tinfoil tape for ease of installation, then installation ease is improved, but contact stability deteriorates leading to temperature inconsistencies

Engineering Contradiction:

Improveinstallation easeVSAvoidtemperature monitoring accuracy

Core Design Contradiction:

Ease of manufactureVSMeasurement precision

Solution Approach 1:

The flexible mechanical mounting method (tinfoil tape) is replaced with a structured mechanical mounting system using brackets and positioning structures. This provides stable, consistent contact between the temperature sensing probe and aluminum pot, improving measurement precision while maintaining ease of installation through modular design.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)
