Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the heating element is turned on locally before use, then the wax reaches ideal temperature, but the user cannot start heating remotely during transit

Engineering Contradiction:

Improveremote control capabilityVSAvoidheating time

Core Design Contradiction:

Ease of operationVSLoss of time

Solution Approach 1:

The patent replaces manual local control of the heating element with an automated remote control system. A microcontroller receives commands via wireless communication (Bluetooth/Wi-Fi) from a mobile device, automatically activating the heating element and regulating temperature through a feedback loop with a temperature sensor, eliminating the need for manual intervention and enabling remote operation.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Measurement precision

If basic visual inspection is used to determine wax quantity, then no additional components are needed, but the measurement is not accurate

Engineering Contradiction:

Improvewax quantity measurementVSAvoiddevice structure

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The patent replaces manual visual inspection with an automated electronic measurement system. Load cells (force sensors) are integrated into the device structure to continuously measure the weight of the wax pot, providing precise digital readings of wax quantity through a microcontroller, which compensates for the added complexity by automating the measurement process.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Adaptability or versatility

If fixed temperature settings are used, then the control system is simple, but it cannot accommodate different types of wax or cleaning mode

Engineering Contradiction:

Improvetemperature customizationVSAvoidcontrol system

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent transforms the static fixed temperature control into a dynamic adaptive system. The microcontroller adjusts heating power in real-time based on feedback from a temperature sensor, maintaining the setpoint temperature through proportional control. This enables flexible temperature adjustment for different wax types and cleaning modes while maintaining system stability.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent implements a closed-loop feedback control system where a temperature sensor continuously monitors the heating element temperature and feeds this information back to the microcontroller. The microcontroller compares the actual temperature with the desired setpoint and adjusts the heating power accordingly, enabling precise temperature control for various wax types and operational modes.

Inventive Principle:

Principle #23Feedback

4Object-affected harmful factors

If the hot lid is placed on the housing surface, then no additional components are needed, but it creates safety hazards

Engineering Contradiction:

Improvesafety hazard from hot lidVSAvoiddevice structure

Core Design Contradiction:

Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The patent extracts the hot lid from direct contact with the housing surface by providing a dedicated lid holder component. The lid holder is specifically designed to receive and secure the lid in a safe position away from the housing, preventing thermal damage and burn hazards while maintaining overall device compactness.

Inventive Principle:

Principle #2Taking out (Extraction)
