Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If two housings are used to house circuits and components, then component protection is improved, but structural strength deteriorates and volume increases
Solution Approach 1:
The device is segmented into three functional zones using mounting plates: a first accommodating space for batteries, a second accommodating space for circuits, and a third accommodating space for electrodes. This segmentation allows each component to be protected in its dedicated space while maintaining overall structural integrity through the rigid mounting plates that form the framework.
Solution Approach 2:
The mounting plates are nested within the housing structure, with the first and second mounting plates arranged along different directions and connected to form the middle frame. The side housings and front housing assembly are then assembled around this nested framework, creating a compact integrated structure that protects components without excessive volume.
2Reliability
If two housings are used to house circuits and components, then component protection is improved, but device volume increases
Solution Approach 1:
The first and second mounting plates are arranged along different directions (first direction and second direction respectively) and connected to form a three-dimensional middle frame structure. This dimensional arrangement optimizes space utilization by distributing components along multiple axes rather than stacking them linearly, reducing overall device volume while maintaining protection.
Solution Approach 2:
The middle frame formed by the mounting plates is merged with the housing structure, where side housings and front housing assembly are integrated around the frame. This merging eliminates the need for separate protective housings, as the frame itself becomes part of the protective structure, reducing total device volume.
3Volume of moving object
If components are arranged in separate accommodating spaces, then space utilization is improved, but device complexity increases
Solution Approach 1:
The mounting plates serve multiple functions: they form the structural framework of the device, create separate accommodating spaces for different components, provide mounting surfaces for circuits and electrodes, and contribute to the overall housing structure. This multi-functionality reduces the need for additional separate structures, simplifying the overall device despite the segmented component arrangement.
Solution Approach 2:
The device is segmented into three functional zones using mounting plates: a first accommodating space for batteries, a second accommodating space for circuits, and a third accommodating space for electrodes. This segmentation allows each component to be protected in its dedicated space while maintaining overall structural integrity through the rigid mounting plates that form the framework.

AI summary
Disclosed is a portable beauty device. The beauty device includes a middle frame, a rear housing, a front housing assembly, an electrode, and a processing circuit. The middle frame includes a first mounting plate extending along a first direction and a second mounting plate extending along a second direction. The rear housing at least partially surrounds the first mounting plate and defines a second accommodating space cooperatively with the first mounting plate. The front housing assembly is arranged on a side of the second mounting plate away from the rear housing, and defines a third accommodating space cooperatively with the second mounting plate. The electrode is arranged in the third accommodating space and at least partially exposes out of the front housing assembly. The processing circuit is arranged in the second accommodating space and connected with the electrode to drive the electrode to discharge. The middle frame is served as a mounting body of the front housing assembly and the rear housing, and defines different accommodating spaces for receiving the electrodes and the circuits respectively, which can not only improve overall structural strength of the beauty device, but also increase utilization of space inside the beauty device.
