Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing scent warmers face difficulties in easily replacing parts, such as power cords and lighting modules, and accommodating different electrical socket configurations, leading to increased complexity and cost due to fixed connections and inefficient incandescent bulbs.
Innovation Solution
A base structure with a support structure, electrical connector, and power cord connector that allows easy connection and replacement of power cords, and includes rigid electrical connections and a modular design for lighting and heating modules, enabling flexibility in electrical standards and reducing the need for frequent bulb replacements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If fixed connections are used for power cords and electrical components, then structural stability is improved, but ease of repair and part replacement deteriorates
Solution Approach 1:
The scent warmer is divided into separable modules including a base, power cord assembly, lighting module, and heating element. Each component can be independently removed and replaced through designated connection interfaces, allowing easy maintenance while maintaining structural integrity during operation.
Solution Approach 2:
The power cord incorporates a flexible connection mechanism that allows dynamic adjustment and easy disconnection. The electrical connections use removable terminals and snap-fit interfaces that transition from a fixed state during operation to an easily separable state for maintenance, resolving the contradiction between stability and repairability.
2Illumination intensity
If incandescent light bulbs are used as heating elements, then lighting function is improved, but energy efficiency deteriorates
Solution Approach 1:
The lighting and heating functions are separated into distinct modules. The lighting module uses energy-efficient LED or CFL bulbs that provide illumination without excessive heat generation, while the heating function is handled by a dedicated resistive heating element. This segmentation allows each component to be optimized for its specific function, resolving the energy efficiency problem of using incandescent bulbs for both purposes.
Solution Approach 2:
The base structure incorporates multiple heating elements and light sources that can be independently controlled. Users can select different operational modes (lighting only, heating only, or both combined) to optimize energy consumption based on actual needs, rather than relying on a single incandescent bulb to perform both functions inefficiently.
3Ease of repair
If modular design with removable power cords is implemented, then ease of repair is improved, but device complexity increases
Solution Approach 1:
The base incorporates a universal power cord connection interface that accepts multiple plug types and configurations. This standardized interface simplifies the replacement process by providing a consistent connection mechanism regardless of the specific power cord variant, reducing the perceived complexity for users while maintaining ease of repair.
Solution Approach 2:
Instead of making the power cord permanent and difficult to remove, the design inverts the approach by creating a deliberately simple, tool-free removal mechanism. The power cord uses a snap-fit or bayonet connection that is intentionally easy to disassemble, transforming what could be a complex electrical connection into a simple mechanical interface that users can easily service.

Implementation Method 1
The heating element heats the plate primarily by conduction, and the plate transfers the heat to the scented wax or oil
Implementation Method 2
The incandescent light bulb heats the bottom of the plate primarily through radiation and convection
Implementation Method 3
The incandescent light bulb heats the bottom of the plate primarily through radiation and convection
Implementation Method 4
The burning wick melts the wax near the wick and pulls the liquid wax, along with the scents included in the wax, up into the wick by capillary action or absorption

AI summary
A scent warmer may include an at least substantially hollow member having at least one inner surface defining an internal cavity therein, a receptacle disposed at a first longitudinal end of the at least substantially hollow member for holding scented material therein, and a support structure configured to support at least one lighting module within the internal cavity of the at least substantially hollow member. The support structure may be a separate member from the at least substantially hollow member. The at least substantially hollow member may be configured to conceal at least substantially all of the support structure when the at least substantially hollow member is placed over the support structure on a flat surface.
