A portable depilation instrument with a shell containing multiple outlets and inlets forming separate channels for an external cooling medium to dissipate heat from different elements, utilizing a heat conductive component and fan system to facilitate independent cooling of each element.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single heat dissipation channel is used for multiple heat-generating elements, then the device structure is simple, but the heat dissipation efficiency is insufficient and temperature reduction is incomplete
Solution Approach 1:
The patent divides the heat dissipation system into multiple independent channels, with each channel dedicated to cooling a specific heat-generating element. The shell is provided with multiple inlets and outlets that form separate cooling paths, allowing independent heat dissipation for the light-emitting body, circuit board, and battery, thereby resolving the insufficient temperature reduction when using a single channel
2Volume of moving object
If the portable depilation instrument is designed small for portability, then it is easier to hold and use, but heat accumulation is more easily formed
Solution Approach 1:
The patent implements multiple heat dissipation channels within the compact instrument body, allowing efficient heat dissipation without increasing the overall device size. Each channel is optimized for its specific heat-generating component, enabling effective temperature control in a small-form-factor device
Solution Approach 2:
The patent utilizes the internal three-dimensional space of the instrument shell to arrange multiple heat dissipation channels in different spatial dimensions. By strategically positioning inlets, outlets, and cooling paths throughout the instrument's volume, the design achieves enhanced heat dissipation capacity without increasing the instrument's external dimensions
3Device complexity
If multiple heat-generating elements share the same power supply, then the device structure is simplified, but it is difficult to dissipate heat from all elements simultaneously and efficiently
Solution Approach 1:
The patent segments the heat dissipation system into multiple independent channels, with each channel corresponding to a specific heat-generating element powered by the same power supply. This segmentation allows simultaneous and efficient heat dissipation for all elements without requiring separate power supplies, maintaining structural simplicity while achieving complete temperature reduction

Implementation Method 1
after being introduced from the inlet, under guidance of the heat conductive component, an 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
an 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 3
under guidance of the heat conductive component, an external cooling medium separately passes through different channels

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.
