Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a heating device is positioned close to the nose to effectively heat inhaled air, then the heating efficiency is improved, but the device becomes less comfortable for prolonged use and harder to position stably
Solution Approach 1:
The device is divided into separate functional modules: a headband component for stable positioning, a flexible hose for routing, and a heating module with heat sink positioned close to the nose. This segmentation allows each component to optimize its function independently while maintaining overall comfort.
Solution Approach 2:
A flexible hose connects the headband to the heating module, allowing the heating element to be positioned close to the nose for effective heating while the flexible connection maintains comfort and adaptability for prolonged wear.
2Temperature
If a heating device is positioned close to the nose to maximize heating effect, then the temperature control is improved, but the device stability and comfort are reduced
Solution Approach 1:
The device separates the stabilizing function (headband) from the heating function (module with heat sink), allowing independent optimization of both stability and temperature control effectiveness.
Solution Approach 2:
The flexible hose acts as an intermediary element that transmits thermal energy from the stable headband position to the heating module positioned close to the nose, decoupling the stability and heating effectiveness requirements.
3Productivity
If existing heating devices are used, then the basic heating function is provided, but they fail to regulate temperature effectively and cause discomfort for prolonged use
Solution Approach 1:
The device incorporates a temperature sensor that continuously monitors the air temperature near the nose and provides feedback to the control board, which adjusts the heater power accordingly to maintain the desired temperature range, ensuring effective and reliable temperature regulation.
Solution Approach 2:
The control board dynamically adjusts the electrical power supplied to the heater based on temperature sensor feedback, changing operational parameters to maintain optimal heating performance and prevent discomfort during prolonged use.

AI summary
A portable device designed to heat the cold air that is inhaled through a person's nose is revealed, thus protecting respiratory function in adverse climates, especially for those suffering from lung diseases and the like, or for those who are susceptible or at risk of acquiring these diseases due to their age or work and need a protection mechanism. This device is composed of a support system and an energy system, wherein the support system guarantees the stability of the device next to the nose of the user, while the energy system heats the air that the user inhales through the nose and allows the user to regulate the temperature of the heat sink located near the nose by means of a control knob.
