Auricle Heating Structure for Stable Wear in Any Posture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ear heating devices face challenges in adjusting the position of the heat generating function based on user posture, and ear canal temperature adjustment devices restrict user posture due to their configuration.
Innovation Solution
An auricle heating device with separate left and right heating devices, each comprising a heating body, holding portion, and fixing portion, which are designed to be worn in the auricle with the fixing portion securing the holding portion to the inner side of the auricle, particularly near the cavum conchae, and including an insertion portion that fits into the external acoustic meatus hole.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the ear heating device covers the entire ear to heat surrounding portions including the base portion, then the heating coverage is improved, but the position adjustment capability deteriorates
Solution Approach 1:
The heating device is divided into a heating body and a fixing portion that can be separately positioned. The fixing portion is inserted into the ear canal while the heating body contacts the auricle surface, allowing independent positioning of each component to achieve both comprehensive heating coverage and adaptability to different user postures.
2Stability of the object's composition
If a connection portion connects a pair of ear canal insertion portions, then the structural stability is improved, but the user posture flexibility deteriorates
Solution Approach 1:
The device separates the heating function (heating body) from the fixing function (fixing portion inserted into ear canal). This segmentation eliminates the need for a connecting portion between ears, allowing each ear to be independently positioned according to user posture while maintaining structural stability through the anchoring effect of the fixing portion in the ear canal.
Solution Approach 2:
The connection portion that links the two ears is completely removed from the design. Each heating device operates independently with its own fixing portion anchored in the ear canal, extracting the constraint that limited user posture flexibility while maintaining sufficient structural stability through the ear canal anchoring mechanism.
3Reliability
If the fixing portion is inserted deep into the ear canal to secure the heating body, then the fixability is improved, but the comfort deteriorates
Solution Approach 1:
The fixing portion utilizes the ear canal space in a different dimensional approach by inserting horizontally into the ear canal rather than deep vertically. This allows the heating body to be secured against the auricle surface while the fixing portion remains in the shallow ear canal portion, achieving reliable fixation without deep insertion that would cause discomfort.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The auricle heating device provides excellent fixability, allowing use in various postures without discomfort, including while lying down, and efficiently heats the auricle while functioning as an ear plug.
Implementation Method 1
the heating body may generate heat using a chemical reaction. the chemical reaction may include a metal oxidation reaction.
