Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single inlet and outlet are used for heat dissipation, then the device structure is simple, but heat dissipation is incomplete causing temperature reduction failure
Solution Approach 1:
The patent divides the heat dissipation system into multiple independent channels, each with its own inlet and outlet. The shell is provided with at least two inlets and two outlets, forming separate heat dissipation pathways that allow different cooling media to simultaneously cool different heat-generating components, thereby achieving complete temperature reduction without increasing overall structural complexity.
2Device complexity
If multiple heat-generating elements are cooled through a single channel, then the device structure is simple, but heat dissipation efficiency is insufficient
Solution Approach 1:
The patent implements separate heat dissipation channels for different heat-generating elements. Each element (such as the light-emitting component and other heat-generating components) has its dedicated cooling pathway, allowing simultaneous and independent heat dissipation from multiple sources, thereby significantly improving overall heat dissipation efficiency.
Solution Approach 2:
The patent applies different cooling configurations to different locations based on their specific heat generation characteristics. Each heat-generating element is equipped with appropriately positioned inlets and outlets tailored to its thermal properties and spatial arrangement, optimizing local heat dissipation performance.

Implementation Method 1
the heat conductive component... the external cooling medium separately passes through different channels and is then discharged from a corresponding outlet, and in this process, the external cooling medium brings heat of the separately passing region out of the shell
Implementation Method 2
the external cooling medium separately passes through different channels and is then discharged from a corresponding outlet, and in this process, the external cooling medium brings heat of the separately passing region out of the shell

AI summary
A portable depilation instrument includes a shell, and a depilation mechanism and a heat dissipation mechanism inside the shell. The shell is provided with at least two outlets and one inlet, the shell introduces an external cooling medium from the inlet, the heat dissipation mechanism includes a heat conductive component, the depilation mechanism includes a refrigeration element and an emitter, the heat conductive component isolates the refrigeration element from the emitter in two mutually sealed channels, namely, a first channel and a second channel, the first channel and the second channel are respectively in communication with two outlets, and one of the outlets allows the first channel or the second channel to pass through inside of the entire shell from one end to the other end. Due to complete isolation and a push force, air can be discharged only from a respective corresponding outlet after a heat exchange.
