Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of energy

If an incandescent light bulb is used to heat aromatic substances, then heating function is provided, but heating efficiency is low and energy consumption is high

Engineering Contradiction:

Improveheating efficiencyVSAvoidenergy consumption

Core Design Contradiction:

Loss of energyVSUse of energy by moving object

Solution Approach 1:

The patent replaces the incandescent light bulb (electromagnetic radiation heating) with a direct heating element that contacts the aromatic substance container, enabling efficient thermal conduction heating and eliminating energy loss from electromagnetic radiation.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces a heating element as an intermediary between the power source and the aromatic substance container, enabling direct thermal energy transfer through contact, which significantly improves heating efficiency compared to remote electromagnetic heating.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Use of energy by moving object

If an incandescent light bulb is used for lighting, then lighting function is provided, but lighting efficiency is low and it violates eco-friendly regulations

Engineering Contradiction:

Improvelighting efficiencyVSAvoidenvironmental compliance

Core Design Contradiction:

Use of energy by moving objectVSObject-affected harmful factors

Solution Approach 1:

The patent replaces the incandescent light bulb with an LED light source, which converts electrical energy directly to light with much higher efficiency and without the harmful electromagnetic radiation and heat waste associated with incandescent bulbs, thus complying with eco-friendly regulations.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Ease of operation

If electrical components are exposed without protection, then ease of access is improved, but safety hazards increase

Engineering Contradiction:

ImproveaccessibilityVSAvoidsafety

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The patent uses a transparent protective cover (shell) that encloses the electrical components including the heating element and LED, providing physical protection and electrical isolation while maintaining visual transparency, thus ensuring safety without compromising the ability to observe the aromatic substance evaporation.

Inventive Principle:

Principle #30Flexible shells and thin films

4Productivity

If a heater is placed close to aromatic substances, then heating efficiency is improved, but risk of overheating and fire increases

Engineering Contradiction:

Improveheating efficiencyVSAvoidfire hazard

Core Design Contradiction:

ProductivityVSObject-affected harmful factors

Solution Approach 1:

The patent uses a transparent protective cover that physically separates the heating element from the aromatic substance container, preventing direct contact and potential fire hazards while allowing efficient thermal conduction through the container base, thus resolving the contradiction between heating efficiency and safety.

Inventive Principle:

Principle #30Flexible shells and thin films

Solution Approach 2:

The patent introduces the container base as an intermediary thermal conduction path between the heating element and the aromatic substances, enabling controlled heat transfer at a safe distance, thus improving heating efficiency without creating fire hazards from direct exposure.

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

A scent warmer, includes a heater for generating electric heat to a heat conductor to heat the fragrance in the inner container of the scent warmer to produce fragrance; and a lighting device integrated in a housing. The lighting device has a candle-like lamp protruding from the upper side of the housing to produce a candle-like light effect, which does not produce chaotic smoke and open flames, and is safe and environmentally friendly. The lighting device includes a first lighting unit that emits light onto a light-transmissive safety lampshade, forming a light effect that shines inside and outside the housing, creating a light decorative effect, enhancing the ambient atmosphere for using the fragrance diffuser, and having a lighting effect, so that the evaporation of the fragrance substance of the scent warmer inside the housing and the amount of the fragrance substance stored can be observed.
