Solution Overview
Problem
The nozzles in existing drying apparatuses prone to overheating and damage due to simultaneous exposure to infrared radiation and hot airflow, leading to safety risks and operational failures.
Innovation Solution
An accessory device comprising a mounting portion, an airflow portion, and a guide component, which creates independent airflow and infrared radiation transmission paths, preventing any area from being simultaneously exposed to both, and incorporating connectors that form a heat transfer path to disperse heat and prevent overheating.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the nozzle is designed to only consider heat resistance to hot airflow, then the nozzle structure is simple, but the nozzle absorbs infrared radiation and hot airflow energy simultaneously causing rapid overheating and damage
Solution Approach 1:
The nozzle is divided into multiple independent segments: a first nozzle body for hot airflow passage and a second nozzle body for infrared radiation passage. This segmentation allows each segment to be optimized independently - the first nozzle body handles thermal loading from hot airflow while the second nozzle body handles optical transmission of infrared radiation, preventing simultaneous absorption of both energy forms in a single structure.
Solution Approach 2:
A reflective plate is introduced as an intermediary element to redirect infrared radiation away from the first nozzle body. The reflective plate acts as a mediator that separates the thermal path (hot airflow through first nozzle) from the optical path (infrared radiation reflected by plate), preventing the nozzle material from absorbing both forms of energy simultaneously and causing overheating.
2Productivity
If the nozzle is exposed to both infrared radiation and hot airflow simultaneously, then the drying efficiency is high, but the nozzle deforms and melts after exceeding heat resistance limit
Solution Approach 1:
The nozzle system is segmented into two separate nozzle bodies that operate in parallel - one dedicated to hot airflow delivery and the other to infrared radiation transmission. This allows the system to maintain high drying efficiency by utilizing both heating methods simultaneously while preventing any single nozzle component from being exposed to combined thermal and radiative loading that would cause overheating.
Solution Approach 2:
The reflective plate serves as a mediator that directs infrared radiation along a separate path from the hot airflow path. By positioning the reflective plate to reflect infrared radiation onto a second nozzle body rather than allowing it to strike the first nozzle body directly, the system maintains effective infrared heating while preventing excessive temperature accumulation in any single nozzle component.

Implementation Method 1
a radiation element for emitting infrared radiation
Implementation Method 2
the first connector and the second connector may not only connect and support the airflow portion, the mounting portion and the diversion portion, but also may form a heat transfer path, and may disperse the heat to the whole when the accessory device is overheated locally
