Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional slingshot-wire-type heating wires are manually wound and mounted, then the heating wire can be installed on the heating core, but the density consistency cannot be ensured and thermal expansion causes deformation and short circuits
Solution Approach 1:
The heating wire is segmented into multiple independent wave-shaped sections instead of a continuous manual winding. Each wave section is pre-formed with consistent dimensions, ensuring uniform density and spacing when mounted on the heating core. This segmentation eliminates the variability introduced by manual winding while maintaining the required heating distribution.
Solution Approach 2:
The heating wire is transformed from a straight or simple coiled form into a wave-shaped configuration with specific geometric parameters (amplitude, wavelength, frequency). This parameter change allows the wire to accommodate thermal expansion and contraction while maintaining consistent spacing and density, preventing short circuits and ensuring uniform heating performance.
2Temperature
If heating wires are mounted on heating core without heat dissipation structure, then the heating core can reach maximum temperature at front end, but heat is gathered at front end and heating wire is damaged
Solution Approach 1:
A heat dissipation structure is extracted and added to the front end of the heating core, separating the heating function from the heat accumulation problem. The heat dissipation structure specifically addresses the overheating issue at the front end without affecting the overall heating performance, allowing the heating wire to operate within safe temperature ranges and preventing damage.
3Reliability
If heating wire is buried in ceramic support, then the heating wire is protected and mounted, but heat dissipation efficiency of air channel is reduced
Solution Approach 1:
The ceramic support structure is designed with differentiated local qualities: in some regions it provides protection and mounting for the heating wire, while in other regions it incorporates heat dissipation channels or reduced thickness to allow efficient heat transfer to the air flow. This local differentiation maintains wire protection where needed while maximizing heat dissipation efficiency in the air channel regions.

AI summary
Provided is a heat gun formed by wave-type heating bodies. The heat gun includes a housing assembly and a heating assembly mounted in the housing assembly, where an air supply assembly is fixedly mounted in the housing assembly. The heating wire is wound into a wave-type structure by dedicated equipment. Compared with a traditional slingshot-wire-type structure, the wave-type structure is capable of resisting deformation of the heating wire at a high temperature and in a process from a high temperature to a normal temperature such that defects caused by thermal expansion and contraction when the heating wire operates or stops can be avoided. After the wave-type structure of the heating wire is wound around a mica plate, a direction of the wave-type structure is exactly perpendicular to a direction of an air channel such that wind generated by a fan behind can blow out heat with maximum efficiency.
