Rotatable USB Scent Diffuser Housing for Heat Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
USB scent diffusers often fail to operate efficiently due to the fragrance emitting member not being optimally positioned to receive heat from the resistor, limiting their effectiveness.
Innovation Solution
A USB scent diffuser design featuring a rotatable first housing connected to a second housing with a fragrance emitting member that can be slidably positioned above a heat-producing circuit board, allowing for adjustable alignment and efficient heat transfer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If the fragrance emitting member is fixed in a static position, then the device structure is simple, but the heat transfer efficiency is insufficient
Solution Approach 1:
The fragrance emitting member is made rotatable relative to the housing through a rotating mechanism, allowing dynamic adjustment of its position. This enables the member to be oriented optimally for heat transfer from the heating element while maintaining structural simplicity through the use of a straightforward rotational joint.
2Productivity
If the fragrance emitting member is positioned to receive optimal heat, then the diffusion efficiency is improved, but the accessibility for replacement is reduced
Solution Approach 1:
The device is divided into separable components: the housing, the fragrance emitting member, and the rotating mechanism. The member can be independently removed from the housing by detaching the rotating mechanism, allowing easy replacement while maintaining optimal heating position during operation.
Solution Approach 2:
The rotating mechanism allows the fragrance emitting member to be dynamically adjusted between an operational position (close to heating element for efficient diffusion) and a maintenance position (accessible for easy removal and replacement).

AI summary
A USB scent diffuser having a first housing rotatably connected to a second housing. Disposed within the first housing is a first circuit board attached to a USB connector, an on/off button, and an indicator light. Disposed within the second housing is a second heat producing, circuit board and a fragrance emitting member. The first and second housing are connected so that the second housing is rotated in relation to the first housing so that the fragrance emitting member is selectively positioned above the second heat producing circuit board.
