Air emitting device with interspace for hair treatment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing air diffusing devices for hair treatment expose hair to prolonged hot air flows, risking damage during the hair drying and curling process, and often lack ergonomic design for user comfort.
Innovation Solution
A hair treatment device with a casing containing a heating element and an external body surrounding it, featuring an interspace with separate outlets for heated and unheated air flows, where the unheated air is channeled through longitudinal slots or holes around a grid with protuberances to distribute evenly and reduce heat stress on hair.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If hot air flow is used for hair drying and curling, then hair drying efficiency is improved, but hair damage increases due to prolonged exposure to high temperature
Solution Approach 1:
The air outlet is divided into two separate outlets: a first outlet for hot air and a second outlet for cold air. This segmentation allows independent control of heated and unheated air flows, enabling the device to provide efficient hair drying through hot air while simultaneously reducing heat damage through cold air, thus resolving the contradiction between drying efficiency and hair protection
Solution Approach 2:
Different regions of the air outlet are assigned different thermal characteristics: the first outlet provides localized hot air flow for efficient drying, while the second outlet provides localized cold air flow for heat protection. This local quality differentiation allows the device to address both drying efficiency and hair damage prevention in different spatial zones
2Ease of manufacture
If the device structure is simplified, then manufacturing cost is reduced, but user comfort and ergonomics deteriorate
Solution Approach 1:
The external body serves multiple functions: it provides structural support for the device, creates the interspace for cold air circulation, and forms the ergonomic grip area for user comfort. By making the external body multi-functional, the device achieves improved ergonomics and user comfort without adding separate components, thus maintaining manufacturing simplicity

AI summary
The present invention refers to an air emitting device for the hair treatment provided with an interspace interposed between the casing that houses the heating element and the external body. In this way, the air present in the interspace is not heated by the heating element. This allows the user to grab the device without getting burned. In addition, the interspace is provided with at least one outlet for the air not heated by the heating element, so that the hair is not subjected to a too hot air jet. This avoids damaging the hair itself, contrary to what happens in known in the art devices where the interspace has no such outlet for the air not heated by the heating element.
